General information
Receiving the shipment
Inspecting the shipment
Do not accept the delivery until you inspect the shipment
on arrival. This is to ensure that all required parts are
present and free of shipping damage. Unpack all items and
compare them with the shipping lists. Contact your sales
representative to report any missing items.
Signature acceptance of equipment implies that the FPHE
unit and all loose components are complete and free from
defects.
Inspect the following parts:
• Roof curb
• Discharge plenum
• Enclosure plugs for the lifting lug locations
• Transition ducts
• Roof ashing
• Miscellaneous hardware
• Weatherproof membrane
• Trim pieces
In addition, check the motor supports, fan, and fan guard
fasteners for tightness. Some fasteners may have loosened
during transportation.
Checking for a leak
Check the coil to verify that the internal gas holding
charge remains intact (15 psi to 25 psi). Maintain this
charge until connecting the refrigerant piping to the unit.
A coil that does not have a charge may have been dam-
aged during transit.
If the charge is not present when the unit is received, you
must pressure test the coil with dry nitrogen gas to con-
rm that it is free of leaks. To leak check the unit, com-
plete the following steps:
1. Install a pressure gauge with a range of 200 psi to
400 psi.
2. Apply a 100 psi to 150 psi charge of dry nitrogen.
3. Hold the charge for 24 hr and observe any signicant
changes in pressure.
Note: The nitrogen charge may change 1 psi to 2 psi for
each 10°F change in temperature.
Transit damage and shortage claim
The consignee must make all damaged freight claims. This
is an ICC requirement. Request immediate inspection by
the agent of the carrier and ensure that all the correct
documentation is completed. Send a copy of the damage
claim to the Frick Service and Warranty department.
Send shortage claims directly to the Frick sales represen-
tative and the Frick factory sales department.
For either claim, include the FPHE unit model number, the
serial number, and the Frick sales order number. Refer to
the FPHE unit nameplate for all of this information.
Safety
Because penthouse evaporator installation, operation, and
maintenance involves operating at high speed and high
voltage, safety is a top priority.
The customer is responsible for providing qualied and
trained personnel to install and operate the equipment.
Consult all local building, occupational safety, electrical,
gas, and other codes applicable to the installation.
A variety of optional safety features are available from
the manufacturer. It is the responsibility of the owner to
determine if the unit is equipped with all of the safety
devices required for the particular application.
Be aware of the following safety considerations:
• Accessibility of the equipment to non-service
personnel.
• The provision of electrical lockout switches.
• Maintenance procedures.
• Automatic control sequences.
CAUTION
Users and installers of this equipment should be aware
of all recommended safety procedures and information
such as AMCA publication 410-90 Safety Practices.
CAUTION
Never open an access door while air unit is in operation.
CAUTION
A fan, even though locked out electrically, can rotate
in a seemingly insignicant air ow. During mainte-
nance the fan blades should be secured to restrict
rotation. Verify that the restrictive device is removed
before putting the fan back into service.
CAUTION
Equipment wired to automatic control devices may
start without warning, resulting in personal injury or
property damage. In many instances, a unit will have
multiple elec trical connection points. To prevent un-
foreseen start-up before beginning work on an FPHE
unit, always lock out all power supplies.
CAUTION
Always replace any protective covers removed for
servicing.
CAUTION
Always replace bolts or locks on latches of access
doors that provide access to areas with moving
parts. This mechanical protection from moving parts
is required by UL 1995.

CAUTION
A number of additional safety issues are discussed
throughout the manual. Read the complete manual
before installing, operating, or servicing the equipment.
Warranty and technical support
NOTICE
For warranty support with the Frick FPHE unit, con-
tact Frick Service at 717-762-2121 and choose Option
4 for Tech Services, or visit www.frickservice.com.
Pre-installation requirements
Training and safety considerations
The Frick FPHE evaporator design uses the nest materi-
als and corrosion protection to deliver dependable and
consistent cooling for coolers and freezers. To ensure the
longest possible system life and dependable, consistent
performance, follow the instructions and guidelines in this
manual.
CAUTION
Frick suggests that only experienced industrial re-
frigeration contractors, operators, and maintenance
technicians be used to install, operate and maintain
the FPHE unit. Before working on the FPHE unit, it is
further recommended that they be provided formal
training on the FPHE’s design and features that in-
corporates reading and understanding this manual.
Installing, operating, and maintaining the Frick FPHE unit
involves rotating machinery operating at high speed and
high voltage. Normal operations and maintenance pro-
cedures may require working at elevations, entry into
enclosed spaces, and the use of hand and power tools. As
a result, safety is the top priority.
Frick suggests that every site installing an FPHE unit ana-
lyze and develop an installation-specic safety regime that
takes into account specic site and unit features, person-
nel qualications, hazard identication, and other safety-
related considerations.
NOTICE
Congure all power switches and controls to provide
an open, safe circuit before and during maintenance
pro cedures, until the system is cleared by manage-
ment for normal online operations. For extended
shutdowns, it is recommended that a qualied tech-
nician remove fuses from fused-disconnect panels
or otherwise open the circuit in an accepted, secure
manner.
Frick suggests incorporating the following operational-
safety elements into every client's FPHE safety require-
ments and safety program.
Fans: all fan covers, guards, and shaft retainers, if any,
must be in place before applying power to an FPHE unit.
Always disengage and lock out power before allowing
interior inspections. To prevent foreign objects from being
sucked into rotating fan blades, never allow operation with
the doors open.
Enclosed space inspections: the inspection of coils, drain
pans, guards, or other components in an enclosed space,
requires machinery lockout and another colleague to look
out, at a minimum. Consult your internal safety policy and
OSHA requirements for additional safety procedures.
Vibration and noise: discontinue or stop machinery that
emits unusual vibration and noise. Investigate and identify
the source of the disturbance and correct before testing or
placing the system back in operation.
Wet surface precautions: poorly maintained and wetted
machinery requires care to avoid electrical shocks from
inadequate or loose eld wiring and connections. All per-
sonnel must lock out and tag machinery before working on
the unit. Correct safety precautions such as using insulat-
ing soles and gloves and a trained colleague to look out
are indispensable.
Ice formation in cold weather can present slip and fall
hazards around a penthouse unit. Ensure ice-related safety
procedures are mandatory when the daily ambient tem-
perature falls below 40°F.
FPHE units operates in a continuous-duty capacity so it is
important that unit installers correctly locate, install, and
connect the units in the eld. It is also imperative to ad-
equately size and correctly install the electrical power and
control wiring, refrigerant lines, and air duct.
Preliminary site layout considerations
Locate all FPHE units for accessibility on the roof and
adequate air ow in and out of the cold space. The Frick
FPHE enclosure has two access doors, one on either side
of the unit. Ensure there is access for service and mainte-
nance to both of these locations.
Air is drawn into the FPHE unit along one side, enter-
ing upward through the bottom of the unit. Colder air is
discharged downward along the opposite side of the unit.
Adequate free ow area must be available for returning air
to enter the bottom of the FPHE unit. Excessive restriction
reduces air ow and in turn the cooling capacity of the
FPHE unit.
It is the owner’s responsibility to correctly locate the FPHE
unit in consultation with a qualied engineer before laying
out structural supports and installing the penthouse unit.
Ensure Frick FPHE units are uniformly supported around
the perimeter either by roof curb or building structural
steel under roof decking.

Installation - Operation - Maintenance
Preliminary eld piping design considerations
Before nalizing the refrigerant piping plans for the new
FPHE unit, discuss related plans for potential expansion of
the refrigeration system and building with your refrigera-
tion system designer and Frick sales representative. Incor-
porating appropriate pipe and opening sizes now, in light
of existing and future needs, is often the most economical
long-term strategy.
CAUTION
Avoid hydraulic lockup caused by trapped liquid.
When there is an increase in ambient temperature
and liquid refrigerant conned in rooftop piping, the
resulting expansion pressure has the potential to
cause refrigerant lines to burst.
CAUTION
All Frick FPHE units require strongly supported and
properly anchored eld piping. NO eld piping is to
be supported by the FPHE unit enclosure itself. Wind
loading, and temperature variation must be consid-
ered to allow for movement between the rooftop
unit, adjoining building, and eld piping. A qualied
cooling system design engineer should provide nal
eld-piping plans and specications.
Electrical power
Frick FPHE units usually require both 120 V/single-
phase/60 Hz and three-phase electrical power.
• The 3-phase power drives the evaporator fans. Frick
may or may not supply factory-installed switch gear
and disconnects. Consult the specic order details when
designing the electrical power system.
• Separate 120 V single-phase power is required to both
sides of the FPHE unit for internal service light, GFI
convenience outlet, and heated freezer door seals.
• An additional 120 V power circuit may be required to
heat trace the condensate drain pan outlet and p-trap.
• The refrigeration system design engineer must provide
separate electrical controls and instrumentation infor-
mation.
Refrigeration
Frick equips the FPHE unit with a cooling coil based on a
specied refrigerant and a specied type of liquid feed.
Each cooling coil is shipped with a low-pressure nitrogen
charge to prevent moisture from collecting inside the
circuits.
It is the refrigeration design engineer’s responsibility to lay
out the refrigerant piping and control valves to service the
FPHE cooling coil. Do not use the FPHE unit or the cooling
coil pipe stubs to support the refrigerant piping system.
The FPHE insulated enclosure is not designed to support
concentrated roof loads. If the cooling coil is serviced by a
ooded surge drum, unit installers must provide separate
supports to transmit the weight of the vessel and piping to
the foundational structure.
Condensate drain
Each FPHE unit is designed with a condensate drain pan
under the cooling coil. The drain pan is internally sloped
to channel the water to the connection end of the FPHE
unit. A threaded male pipe stub is run to the outside of the
FPHE enclosure. Pipe this stub with a p-trap to prevent air
migration through the drain line. In addition, environmen-
tal conditions may make it necessary to heat trace this
drain line.
When planning the installation of the penthouse unit, the
elevation of this drain connection and the need for a drain
trap are often important when determining the unit sup-
port and the possible benets of a roof curb.

Installation safety guidelines
Electric
Check the unit nameplate to verify that the power be-
ing provided corresponds with the requirements of the
equipment.
Ensure
that only qualied electricians install
the power supply and xtures, and that they conduct all
electrical work in accordance with local codes.
All electrical conduits entering the FPHE enclosure walls
must be non-metalic inside the wall to minimize heat
transfer. After the electrical conductors are run inside
those conduits, thoroughly seal the inside of the conduits
with electrical putty or caulk to prevent moisture migra-
tion. Failure to follow these guidelines may result in the
accumulation of water or ice in the electrical boxes and
conduits inside the FPHE.
It is important to congure all power switches and controls
to provide a safe circuit. Poorly installed, maintained, or
wetted machinery could lead to electrical shocks.
Fans
Ensure all fan covers, guards, and shaft retainers, if any, are
in place before applying power to the unit. Always turn off
electrical power and use lock-out/tag-out procedures be-
fore interior inspections, testing, or starting the FPHE unit.
Vibration and noise
Immediately stop machinery that emits unusual vibra-
tion or noise. Investigate the source and resolve the issue
before placing the unit back in operation.
Support structure information
The Frick FPHE unit consists of the penthouse enclosure
assembly and possibly a roof curb for mounting. You must
anchor these components to a suitable support structure
such as building structural steel or roof decking. Ensure
the structure is capable of supporting the dry shipping
weight of the unit plus any refrigerant within the coil; any
frost or ice that may accumulate on the coil, the weight
of any ancillary items attached to the unit enclosure, such
as electrical panels, and any live loads imposed due to
operating fans and moving air. The weight that the sup-
port structure must support and the associated anchoring
requirements also varies as a result of externally imposed
loads, such as expected snow or ice buildup, seismic, and
wind loading.
Ensure the structure is designed for at least 110% of the
operating weight of the FPHE unit distributed as a uni-
form load around the perimeter of the enclosure support
surface.
Ensure the support structure where you are locating the
FPHE units is rigid and level, and shim if necessary. Place
shims, as required, at intervals no greater than 3 ft apart
and do not use them to compensate for signicant surface
slope. Ensure the sum total of any individual stack of shims
does not exceed 1/2 in. and only use them to compensate
for surface irregularities.
Secure the FPHE unit to the support structure. It is the
installer’s responsibility to ensure the unit is secured in
accordance with applicable building and earthquake codes.
If the support structure is in the form of parallel steel
beams, size the beams in accordance with standard engi-
neering practices.

Roof curb
Preparing the roof curb
Unless specifically indicated on the project drawings, Frick
provides the roof curbs for use with the FPHE unit fully
assembled.
1. Check the roof curb for any damage that may have oc-
curred during shipment: corner welds, bottom resting
surfaces, upper FPHE unit mating surfaces, and anges.
2. Check the roof curb for square by comparing the two
diagonal measurements.
3. Check that the rooftop mounting surface and any
opening in decking and insulation is adequate for ac-
cepting the curb dimensions.
4. Locate the gasket material that is shipped loose with
the curb. Apply this to the curb just before setting the
FPHE unit on the curb.
Rigging the roof curb
The roof curb is provided with an interior perimeter ange
that contains slotted holes for attaching the FPHE unit to
the roof curb, in addition to a number of circular holes
near each corner. Use these circular holes to attach rig-
ging clevises for lifting the curb into place as shown in
Figure 6.

NOTICE
If you are not setting the FPHE on a roof curb, pro-
ceed to Rigging and lifting the FPHE unit.
Setting the roof curb
The roof curb is designed to set directly on support steel.
The load bearing region of the roof curb is the interior
perimeter of the curb as indicated on Figure 7.
The roof curb must be supported uniformly around the
entire interior perimeter. Apply shims as necessary. Space
shim packs no more than 36 in. apart and do not exceed
1/2 in. thickness. Do not use shims and blocking to adapt a
curb to roof pitch.
It is the responsibility of the installing contractor to secure
the roof curb to the supporting structure in accordance
with local building codes. If welding is used, place the
light stitch welds along the outside perimeter of the 11
gauge lip as shown in Figure 7. Welding along the inside
perimeter may result in damage to the thermal barrier and
insulation.

WARNING
When lifting the FPHE unit, weight may not be
evenly distributed causing the unit to be unbalanced
or top heavy. See Figure 10 for recommended lifting
procedure.
Rigging and lifting the FPHE unit
1. Using the lifting lugs provided, attach spreader bars
and rigging as shown in Figure 10. Spreader bars are
required to prevent damage to the cabinet and pro-
truding components during a lift.
2. Cooling coil is not centered inside the enclosure and is
likely offset the center of mass. Adjust the tension in
each line for the correct load distribution.

CAUTION
If you do not rig or lift the unit carefully, you could
damage the unit, hurt yourself or others.
Setting the FPHE unit
1. When setting the FPHE unit on a roof curb, rst apply
two strips of 1 7⁄8 in. wide neoprene gasket material
around the top surface of the roof curb. Position the
inside strip of gasket material a third of the way inside
the load bearing point of the mating surface. Ensure
the outside strip is approximately 1/4 in. from the out-
side edge of the curb nailer. See the following gure.
Figure 12: Applying roof curb gasket
Callout Description
A Two 1 7/8 in. x 1/2 in. neoprene gaskets
B Support structure
C Load bearing point
2. As the FPHE unit is being positioned overhead, it may
be benecial to spray the neoprene gasket with a light
mist of water. This allows slight adjustments while
the FPHE unit is aligned for nal positioning. The use
of drift pins also facilitates positioning the FPHE unit
on the roof curb so that the attachment bolts can be
installed easily.
3. Install the ange bolts around the inside perimeter
ange. Insert the bolts downward with the nuts being
installed on the bottom side of the ange. Space the
attachment bolts uniformly around the inside perim-
eter ange with no more than 14 in. between adjacent
bolts. See Figure 3 and Figure 6.
Setting the FPHE unit without a roof curb
1. When setting the FPHE unit without a roof curb it is
unnecessary to apply a sealing gasket. The FPHE base
structure may be set directly on supporting steel.
2. The FPHE base needs to be supported uniformly around
the entire interior perimeter. Apply shims as necessary.
Space shim packs no more than 36 in. apart and do not
exceed 1/2 in. thickness. Do not use shims and blocking
to adapt the FPHE base to a pitched roof.

Installing the roof membrane
You must protect the FPHE units with a membrane roof
cover, which consists of the following components:
• Membrane roof cover
• Termination trim, plastic
• Black Phillips head metal screws
• 2 in. truss plates
• Caulking
Before you install the membrane, keep the following points
in mind:
CAUTION
The membrane is very slippery when wet.
• Keep sharp objects such as nails or screws off the
roof. Someone stepping on them could puncture the
membrane.
• Do not allow hot objects to touch the membrane.
• You can temporarily repair any punctures or holes that
occur during installation with duct tape or caulking.
However, you need to make any nal repairs using a
heat gun.
For correct weather protection, complete the following
steps:
1. Unpack the membrane roll, being careful not to cut the
membrane.
2. Unroll the membrane over the roof area, ensuring the
tabs are on the underside and that the roof area is free
of debris.
3. Maneuver or shift the membrane so it ts squarely over
the roof area, allowing equal amounts of membrane
to overhang at least 6 in. on the edges of the roof. In
windy conditions, place a heavy object, such as con-
crete blocks or tires, around the perimeter to keep the
wind from lifting the membrane.
4. After centering the membrane on the roof, either fold
or roll the membrane back towards the center of the
roof so the underside tabs are exposed. The roll or fold
must be parallel to the factory seam and tab.
5. Stop rolling or folding when you reach the tab going in
the opposite direction.
6. Begin to roll or fold the membrane back until a tab is
exposed and the tab is at on the roof deck.
7. Install the 2 in. truss plates along the fastening tab us-
ing the Black Philips screws, keeping them spaced 12
in. O.C.
Note: Do not screw directly over a ceiling panel seam.
Stay 6 in. away from any of these seams.
8. Continue to roll the membrane until the next tab is
exposed and in place, ready for fastening.
9. Pull the tab tightly to reduce any wrinkle that may oc-
cur. After pulling the tab, hold it in position until you
can secure it with a couple of fasteners.
10. Install the fasteners along the tab 12 in. O.C.
11. Complete steps 9 and 10 for every tab.
12. Hold the membrane that is overhanging the edge of the
roof tight and install the termination bar at least 5 in.
below the horizontal roof. If the termination bar has a
caulking lip, ensure the lip is on the upside.
13. Fasten the termination bar using the pilot holes with
the Black Philips head screws.
Figure 14: Fastening the termination trim
14. After attaching all termination bars, trim any excess
membrane that is exposed under the termination bar
with a sharp knife, using the bottom edge of the bar as
a cutting guide.
15. Caulk the top edge of the termination bar.

Sealing the FPHE enclosure
The FPHE enclosure insulated panels may have shifted
during transit. It is important to inspect all panel seams
and reset the cam-locks as necessary.
1. Inspect all panel seams to ensure that the sealing gas-
ket is visibly compressed. If it is not, remove the snap
plugs at the cam-lock, use an allen wrench to com-
pletely unlock the cam latch and then reset and relock
it. Reinstall the snap plugs.
2. Inspect all panel corners to be sure that adjacent pan-
els are not racked; loosen the required cams, adjust the
panels then reset and relock the cam-locks.
3. Although the FPHE enclosure is completely sealed
when assembled at the factory, additional caulk may be
required on either interior and exterior panel seams.
Frick suggests the use of a silicone DOW RTV-732 food
grade caulk for any interior seams. Use rainbuster 1200
for resealing any external seams.
4. Use caulking or insulating sealant to nish the exterior
joint between the FPHE enclosure and the roof curb
before the surrounding roong is sealed to the unit
5. Inspect each of the FPHE enclosure freezer door rain
hoods. Tighten any loose attachment screws and caulk
as necessary.
6. Remove all of the lifting lugs by removing the mounting
bolts in each one. Discard the lifting lugs and bolts.
7. Insert the lifting lug plug into the opening. Take care
not to damage the inner and outer seal strips. Attach
the plug into place using the screws provided. Plug all
of the factory-drilled screw holes.
8. Seal the building roof insulation to the FPHE enclo-
sure or the roof curb. Use a cant or radius around the
perimeter of the enclosure or curb.
For installations involving a roof curb, it is necessary to
use roof membrane or ashing to cover the exterior of the
curb including the curb to FPHE enclosure joint. Ensure the
nal nish includes a caulked seal strip as shown in Figure
4.
If you are not using a roof curb, the location of the seal
strip is subject to the discretion of the installer that installs
and seals the roof.

Discharge air plenum
The discharge air plenum and interconnecting circular
ducts components ship separately from the FPHE unit.
It is intended that the FPHE discharge air plenum be sup-
ported independently of the FPHE unit or its supporting
roof curb.
Preparing the discharge plenum
1. Inspect the air discharge plenum for any obvious ship-
ping damage.
2. Install a prefabricated circular duct transition to each
plenum air inlet orice using tapper screws. The FPHE
fans are provided with a transition duct attachment.
See Figure 18.
Figure 17: Fan discharge nozzle integral to module
3. The interconnecting duct material is provided as pieces
of at stock. Take one piece of at stock, roll it into a tube
that is approximately 33 in. in diameter. Secure it with a
strap to prevent it from unrolling. Stand the roll inside one
of the plenum air inlet openings. Repeat this process for
each fan discharge duct.
Installing the discharge plenum
1. Lift the plenum into position taking care that the coiled
duct material does not get damaged. Mount the
plenum using support rods as indicated on the Frick
FPHE plenum drawing. See Figure 19 for an example.
Note that each plenum hanger rod must pass through
the upper alignment bracket and support the assem-
bly by the lower bracket. Use the double nuts jammed
together to secure the nal adjustment.
2. Each fan discharge must be connected to the plenum
using the coiled at stock material. Carefully measure
the distance between the FPHE fan discharge nozzle
and the plenum transition duct inlet. Mark the outside
of the coiled duct at stock so that approximately 50%
of the excess is available for insertion and attachment
into the fan discharge nozzle. Ensure that the remaining
50% is available to extend into the plenum transition
for attachment.
3. Carefully lift the coiled duct material and insert it into
the fan discharge nozzle. Allow it to uncoil and attach
it to the fan nozzle using tapper screws. Install screws
spaced approximately 18 in. apart.
4. Attach the coiled duct material to the lower plenum
duct transition assembly using tapper screws, again
spaced approximately 18 in. apart.
5. Secure the vertical duct seam using tapper screws
spaced a maximum of 12 in. apart.

Electrical
The Frick FPHE as standard does not provide high voltage
power wiring to fan motors.
An optional feature that is provided: Individual motors
wired to the unit exterior and placed in a NEMA 3R or 4
power distribution panel.
Other options are available, please refer to order-specic
wiring diagrams.
See Figure 23 and Figure 24 for standard suggestions
for wiring multiple parallel fans. When power wiring the
fans on the installation site, it is the installing contrac-
tor’s responsibility to ensure that the electrical design and
installation meet the applicable codes.
For FPHE units with factory wired motors, refer to the
order-specic wiring drawings provided.
120 V service power
Each Frick FPHE units is provided with internal lights,
exterior light switches and external convenience outlets
located by each access door. For FPHE units designed to
operate below 32°F, the access door seals are also heat
traced. Each access door and associated components are
internally wired and require 120 V eld supplied power to
an external electrical junction box. See Figure 20.

Refrigeration
The Frick FPHE unit may be provided with a cooling coil
designed for any direct or secondary refrigerant. Refer to
the original order documentation for specic information.
The FPHE cooling coil is provided with a nitrogen charge.
This charge prevents moisture from migrating inside the
refrigerant circuits, collecting and contaminating the future
cooling system.
CAUTION
Care must be taken when initially opening the ends
of the refrigerant pipes to make eld connections
as injury could occur due to the positive nitrogen
charge.
NOTICE
Once the cooling coil refrigerant piping has been
opened, maintain a dry nitrogen charge in the pip-
ing system if the coil is not charged with refriger-
ant immediately. Failure to do so could result in the
collection of moisture inside the coil circuits and
the possible contamination of the future refrigerant
charge.
Refrigerant piping
CAUTION
The unit connections are not designed to support the
weight of piping, valves, or ttings.
The cooling coil refrigerant connections are weldable pipe
stubs, anges, or threaded pipe caps. The project submit-
tal drawings indicate the coil connections for a specic
unit. It is important to correctly size and orientate the
refrigerant lines servicing the cooling coil in order for the
coil to function correctly.
Refrigeration piping design and line size selection are the
responsibility of the unit installers. Conrm that the system
design parameters comply with the coil design parameters
stated on the certied submittal drawings. Before con-
necting the refrigerant lines to the coil, verify that the pip-
ing and control valves on the unit are correctly supported.
Design all piping to minimize the transfer of vibration to
the unit and allow for thermal expansion of piping.
CAUTION
Avoid hydraulic lockup caused by trapped liquid.
When there is an increase in ambient temperature
around conned liquid, the expansion pressure could
cause refrigerant lines to burst.
When the Frick FPHE unit is provided with hot gas drain
pan heat, the pan coils are not factory-piped to the
evaporator refrigeration piping. Design of the refrigerant
control valve group and the interconnecting pan and coil
piping must be done by a qualied refrigeration engineer.
The required refrigeration piping must be done in the eld
by qualied pipe tters.
CAUTION
Use of a refrigerant other than that stamped on the
nameplates may cause damage to the refrigeration
coils. Coils must not be subjected to higher pressure
than the design pressure stamped on the nameplate.
In ammonia systems, be sure to use refrigerant
grade, not agricultural grade ammonia.
Flooded surge vessels support
The FPHE unit is not designed for ooded operation. The
enclosure and pipe stubs are not designed to support a
ooded surge vessel.
Evaporator condensate drain piping
The cooling coil condensate drain pan is provided with a
male pipe thread (MPT) pipe stub out the end of the pan
and extending through the FPHE enclosure.
Although the height may vary slightly from model to
model, in general the bottom of the drain pan connection
is approximately 9.75 in. above the bottom of the FPHE en-
closure panels. If the unit is mounted on a roof curb, this is
approximately 9.75 in. above the top of the roof curb.
Due to static pressures inside the FPHE unit enclosure, it
is necessary to trap the condensate drain. This is generally
done with a P-trap. It is the responsibility of the installing
contractor to be sure that the condensate water is piped
according to applicable codes.
Figure 24: MPT condensate drain
Callout Description
A Drain pan drain connection
NOTICE
When mounting a Frick FPHE unit directly on building
steel, be sure to allow enough elevation to properly
trap the condensate drain pipe. See the project sub-
mittal drawings for available height.
FPHE units are designed for freezer applications and may
be installed in climates that have low outdoor tempera-
tures during the winter. If either of these conditions apply
it is advisable to provide heat trace of the condensate
drain piping. Consult a refrigeration design engineer for
selection and application of the heat trace product.
