IDSC2 EVAPORATIVE CONDENSERS
INSTALLATION - OPERATION - MAINTENANCE
General information IDSC2 units are designed to provide optimum efciency
and an extended life when properly installed, operated
and maintained. As a result, it is highly recommended that
a comprehensive maintenance schedule be developed
and undertaken on a regular pre-determined basis. This
manual assists the owner – operator in developing such a
schedule.
This equipment is relatively complicated and the instal-
lation, operation, maintenance, and servicing must only
be carried out by suitable individuals who are qualied to
carry out these functions. These individuals must also be
familiar with and comply with all applicable governmental
standards and regulations pertaining to the function(s).
NOTICE
The type of refrigerant must comply with what is
indicated on the submittal drawings and/or unit’s
nameplate. Design operating pressures, as indicated
on the nameplate, must never be exceeded.
NOTICE
Evaporative condensers and uid coolers and all
piping systems must be correctly evacuated before
charging the system with refrigerant, to ensure the
complete removal of moisture and non – condens-
ables from the entire refrigerant circuit.
NOTICE
For evaporative condenser and uid coolers instal-
lations that are installed at or near coastal areas,
speak to your Frick representative to conrm the
material combination compatibility.
NOTICE
In locations where the uid within the evaporative
uid cooler could possibly freeze due to ambient
temperatures dropping below freezing, drain the uid
from the coil when the ambient temperature is at or
below 40˚F.
WARNING
Failure to comply with any of these requirements could
result in serious damage to the equipment and/or
the property where it is installed, as well as personal
injury and/or death to themselves and/or people at the
specic location.
Warranty statement
Frick warrants the product to be free from defects in
workmanship and materials under normal usage for a peri-
od of 24 months from the date of purchase (the “Warranty
Period”), provided that the product is correctly installed
and operated within the recommended limits of Frick’s
technical documentation. This warranty is only valid if the
product is given normal and proper use and complies with
Frick‘s installation and maintenance instructions.
Safety instructions
• Only qualied personnel who are familiar with this type
of equipment must carry out installation and mainte-
nance.
• Always wear safety glasses, gloves, and head protec-
tion when working on the equipment.
• Avoid contact with sharp edges as these can cause
painful lacerations.
• All units must be properly evacuated before charging
the system.
• Before undertaking any work, verify that the power is
switched off and that the unit is properly disconnected,
locked out, and tagged out.
• Never apply heat to a sealed refrigeration system.
• Keep hands away from fans when the unit is running.
• Ensure all mounting bolts are tight and are the correct
length for the specic application.
• Do not remove any of the safety labels from the unit.
• Maintain all safety labels on the unit in good condition.
If required replace with new.
WARNING
Although halocarbon refrigerants are classied as safe
refrigerants, certain precautions must be observed
when handling them. Refrigerants can be harmful if
inhaled. When released to the atmosphere in the liquid
state, refrigerants evaporate rapidly, freezing anything
they contact. Use and recover refrigerants responsibly.
Failure to follow this warning may result in personal
injury or death.
DANGER
Anhydrous Ammonia (NH3):
Specic precaution must be adhered to when people
are working with or are exposed to Anhydrous Am-
monia.
Ammonia is considered a high health hazard because
it is corrosive to the skin, eyes, and lungs. Exposure to
300 parts per million (ppm) is life threatening. Am-
monia is also ammable at concentrations of approxi-
mately 15% to 28% by volume in air. When mixed with
lubricating oils, its ammable concentration range is
increased. It can explode if released in an enclosed
space with a source of ignition present, or if a vessel
containing anhydrous ammonia is exposed to re.
Personal protective equipment must be worn at all
times when working with Ammonia. For systems that
have an operating charge greater than 10,000 lb a pro-
cess safety management program is mandatory. More
information on this topic is available from OSHA.
Failure to follow this warning may result in personal
injury or death

Terminology
The following descriptions are provided to ensure all per-
sons working with the IDSC2 equipment are familiar with
the terminologies used.
Basin: An assembly located at the base of the unit de-
signed to hold a volume of recirculated water while pro-
viding connections for the water recirculation pump, drain,
and overow. It is also known as a pan or sump.
Water recirculation pump: Closed-coupled, centrifugal
type impeller, with mechanical seal required to circulate a
specied ow rate of water over the heat exchange coil(s).
Basin section (induced draft unit): An assembly com-
prised of the basin, support columns, air inlet louvers,
make-up water connection, and other small parts required
for proper unit operation in the eld. The basin section is
usually shipped separate from the rest of the unit.
Basin section (forced draft unit): An assembly comprised
of the basin, support columns, axial motors/fans, enclosure
panels, make-up water connection, and other small parts
required for proper unit operation in the eld. The basin
section is usually shipped separate from the rest of the
evaporative unit.
Inlet louvers: Enables ambient air to enter the unit at the
basin section, while preventing water from splashing out
and direct line of sight into the basin during unit operation.
There are many different proles, sizes, and materials of
construction.
Sump/strainer connection: Appropriately sized cross-sec-
tional area, box or pipe, that is greater than or equal to the
suction connection size of the water recirculation pump.
140.020-IOM (OCT 2020)

IDSC2 EVAPORATIVE CONDENSERS
INSTALLATION - OPERATION - MAINTENANCE
Strainer: An assembly used to catch large suspended par-
ticles in the recirculating water before entering the water
recirculation pump. Periodic maintenance is required to
keep the strainer clean.
Drain connection: Appropriate sized pipe, usually MPT,
extending from the lowest point of the basin to facilitate
basin drainage.
Overow connection: Appropriate sized pipe, usually
MPT, extending from the highest point of the basin, con-
nection end to prevent spill out from the air inlet louver
section and bleed off.
Casing: Perimeter panels of the fan and/or coil section of
the unit which house all interior components.
Coil section: An assembly comprised of the heat exchange
coil(s), tube sheets (IDSC2 only), casing, and any other
structural members required.
Condensing coil: An assembly comprised of tubes, head-
ers, connections, and framing, in a specic serpentine
arrangement such that circulating refrigerant is condensed
when operating with other unit components. It is also
known as the heat transfer coil.
Axial fan section: An assembly comprised of the fan(s),
fan motor(s), fan nozzle(s), fan motor mount(s), framing,
casing, drift eliminators, and water distribution system.
Fan motor mount: An assembly comprised of heavy
gauge sheet metal, or structure, to rigidly support a single
motor and fan coupled together.
Drift eliminators: Located above the water distribution
system to remove entrained water droplets in the leaving
air stream.
Water distribution system: An assembly comprised of
a water distribution box (or header), water distribution
branches (or pipes), water spray nozzles and other minor
parts to fasten, seal, and secure all parts in place.
Riser pipe: Water pipe which connects the discharge side
of the water recirculation pump to the water distribution
box (header) entrance.
Bleed valve: Located on the lower portion of the riser pipe
where the discharge side of the valve connects to the top
of the overow drain connection (basin). It is necessary to
set the appropriate amount of water “bleed” from the unit
to maintain the appropriate cycles of concentration. Also
known as a blowdown valve.
Lifting lug: Heavy gauge or multiple heavy gauge plates,
joined together, with a large hole to accommodate the
attachment of an industrial lifting connection, for example,
screw pin shackle. Also called a lifting ear.
Mechanical oat make-up assembly: Make-up water
valve with armature and circular or pancake type oat for
basin water level adjustment.
Make-up water connection: Appropriate sized pipe,
usually MPT, extending from the vertical louver support
at the connection end. This connects to the mechanical
oat make-up assembly located inside the basin section to
facilitate make-up water feed.
The following are possible accessories available for IDSC2
units.
External service walkway package: OSHA approved, self
–supporting, external walkway assembly, which includes a
vertical access ladder, connected to the unit. This enables
access to the unit fan section, eliminators, and water
nozzles.
Remote sump: A separate basin, or water tank, located
inside a structure that must be kept above freezing tem-
peratures. It is used to hold/circulate the water used by
the unit instead of the standard basin with pump supplied.
A remote sump connection in the unit basin is provided for
this option.
Electric heaters: Electric immersion heaters to ensure
the basin water does not freeze. Basin water temperature
maintained is approximately +40°F.
Electronic water level control: External stand pipe with
level sensor elements to control a separate solenoid valve
to provide make-up water to the basin.
Motor davit: An assembly connected to the unit used to
facilitate lifting the fan and/or motor from the fan motor
mount.
Water silencers: Located in the basin above the operating
water level. This option reduces the overall noise level of
the unit.

Installation • Ensure that there is sufcient space for maintenance.
• Ensure that all liquid-carrying components, connec-
tions, lines, and all electrical connections and lines are
easy to access.
• Ensure that the pipe connection points are visible.
NOTICE
Lightning protection rods beside the unit are recom-
mended.
If you intend to put the units into a dual or quad position,
increase the height of the louver section in the single box
sizes to ensure sufcient air intake. See Figure 1 to Figure
4 and Table 1.
WARNING
Refer to the submittal package for specic unit infor-
mation.
Equipment layout
Location layout
Ensuring optimum performance of the unit with unobstruct-
ed airow is the responsibility of the installing contractor. In
order not to compromise the performance of the unit, loca-
tions on open rooftops or at ground level with no obstruc-
tions such as walls or adjacent buildings are optimal.
When optimal locations are not possible, position units so
that the discharge air is either level or higher than these
adjacent obstacles. It is imperative that the location allows
for unrestricted airow into each unit and that there is no
recirculation of the saturated discharge air. It is also advis-
able that the discharge air is not in the direction of, or in
close proximity to, any air intake location for the building’s
ventilation system.
Other points to consider when selecting the installation
location include the following:
• Place the unit so you can monitor and control it from
all sides at all times.

IDSC2 EVAPORATIVE CONDENSERS
INSTALLATION
The IDSC2 is an induced-draft, counter-ow, evaporative-
cooled product line consisting of a four-sided air entry
conguration. Properly evaluating equipment location
leads to a successful installation, and subsequently, proper
operation. This manual provides suggestions for vari-
ous layout scenarios including placing equipment in close
proximity to an obstruction, such as a wall. In addition,
Frick offers both dual and quad unit congurations which
increase the air inlet openings appropriately, in com-
parison to a single unit, to enable the absolute minimum
clearance between units. See Figure 5 to Figure 10 for
details.
The list of minimum clearances between an obstruction
and the air inlet side or end is a guideline only. There
are always circumstances, for example prevailing winds,
coupled with eld experience, which lead to alternate lay-
outs that would increase a minimum clearance presented
in this manual to achieve proper operation.
It is best practice to place the equipment in a free-eld
environment when possible, to ensure the required ambi-
ent airow and prevent recirculation of the saturated
discharge air. Units on open rooftops or at ground level
with no obstructions, such as walls or adjacent buildings,
are the optimum location. However, in many instances this
is not possible. Positioning in wells, next to high walls,
adjacent buildings, occupied areas, or specic enclosures
all pose a risk of recirculating the saturated discharge air.
This increases the wet bulb temperature of the intake
air and compromises the performance of the condenser,
which can result in higher condensing temperatures. Use
discharge hoods or duct extensions in such instances.
Single/multiple unit layouts
All minimum clearance values indicated are for IDSC2
induced draft units only. In addition, overall nominal unit
lengths are also indicated. A unit is a specic model num-
ber which consists of a single nominal box size or multiple,
single boxes arranged in very close proximity. See Table
1 for model dimensions. There are three different unit
congurations available: single, dual, and quad. A dual
unit, for example, can be two, 12 ft x 12 ft single boxes
positioned end-to-end which is designated as one model
number and is considered one unit. Figure 5 to Figure 10
highlight different potential layouts in which you can prop-
erly locate a unit or units on-site.

NOTICE
Refer to the submittal package for specic unit infor-
mation.
Use Neoprene gasketing between the I-beams and the
base of the unit.
NOTICE
If Neoprene gasketing is not used, corrosion may oc-
cur between the dissimilar materials.
I-beams must be level, with no deviance greater than 1/8
in. over a 6 ft span. Do not use shims to level the unit as
this compromises the load bearing surface.
Use the mounting holes of 13/16 in. diameter at the base
of the basin section, in the side panel anges, for securing
each unit to the support structure using 3/4 in. diameter
bolts. Refer to the Frick unit certied drawing for the bolt
hole locations.
The installing contractor, the building contractor, or some
other relevant party must provide all support beams and
anchoring bolts, which you must select in accordance with
sound structural engineering standards. When select-
ing the support beams, calculate deection by using 55%
of the unit’s operating weight as a uniform load on each
beam.
NOTICE
The support beams must be level at the top and meet
industry acceptable tolerance related to the overall
length of the unit installed. Do not level any unit with
shims.

INSTALLATION
Ofoading and assembly
Compare the data on the nameplate of the unit with the
submittal information to verify you received the correct
unit. Verify model nomenclature and electrical data with
the original order.
NOTICE
Remove any loose parts which were shipped in the
basin section of the unit before installation, when
applicable.
Installing the basin
1. See Rigging and Hardware for instructions on rigging
the basin.
2. Slowly lift the basin section from the shipping support
structure, move to the installation location, and set on
the support structure.
NOTICE
Take care when lifting the basin section so that it is
lifted level with little or no tilt. This ensures the drain
connection pipe does not come in contact with the
ground or any objects in order to prevent damage.
3. Check the position of the basin on the support struc-
ture to ensure proper positioning and that it conforms
to the information provided in Support Structure.
4. Secure the basin section of unit to the support struc-
ture with suitable 3/4 in. diameter bolts (not provided).
• Use all of the bolt holes to secure the unit to the
support structure. For bolt hole locations, refer to
the Frick unit certied drawing.
5. Prevent stresses on the unit:
• Check that all mounting bolts are tightened equally
to ensure balanced load distribution.
See Riser Pipe Coupling Installation before rigging the up-
per casing section.
Fitting the upper casing section
1. See Rigging and Hardware for instructions on rigging
the upper section.
2. Slowly lift the upper section and move to the installa-
tion location to t the upper section on top of the basin
section.
Figure 32: Lifting the top section of the unit
3. Align the upper casing section with the basin section.
Figure 33: Aligning top and bottom sections
4. Appropriately guide the upper section safely into the
recess and ensure it is free from pinch points.

NOTICE
There is already a clearance “gap” designed between
the polyvinyl chloride (PVC) riser pipe in the basin
section and upper section. Take care when lifting the
upper section such that it is lifted level (with little or
no tilt) to ensure the PVC riser pipe does not come in
contact with the ground, any objects, or the basin sec-
tion in order to prevent damage.
Connection joint
Bolt the upper casing section and the basin section to-
gether using the connection joint.
Installing the riser pipe coupling
1. Align the casing to the basin then proceed with tight-
ening the union nut.
Figure 35: Casing
2. Install the cover with M6 x 20 (10x) screws and wash-
ers.

instructions.
Inlet louvers
• The narrower inlet louvers t into the inlet louver
openings on the front and back of the unit.
• The wider inlet louvers t into the inlet louver openings
on the sides of the unit.
• Position inlet louvers so that the louver pattern points
downward into the basin section. See Figure 37.
Figure 37: Positioning louver
• After installing the inlet louvers, the top is held in place
by the inlet louver front supports. See Figure 38.
