IDSC2 EVAPORATIVE CONDENSERS

INSTALLATION - OPERATION - MAINTENANCE

General information IDSC2 units are designed to provide optimum efciency

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 qualied 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 conrm 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

specic 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 qualied 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 specic 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 classied 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):

Specic 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 overow. It is also known as a pan or sump.

Water recirculation pump: Closed-coupled, centrifugal

type impeller, with mechanical seal required to circulate a

specied 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 proles, 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.

Overow 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 specic 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 overow 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 sufcient 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 sufcient air intake. See Figure 1 to Figure

4 and Table 1.

WARNING

Refer to the submittal package for specic unit infor-

mation.

Equipment layout

Location layout

Ensuring optimum performance of the unit with unobstruct-

ed airow 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 airow 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

conguration. 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 congurations 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 airow 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 specic 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 specic 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

congurations 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.

Support structure

Use two parallel I-beams traversing the entire length of the

unit to structurally support the units. See Figure 11.

Figure 11: IDSC2 steel support dimensions

A1 A2 A3 A4

NOTICE

Refer to the submittal package for specic 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 certied 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 deection 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

Ofoading 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 certied 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.

INSTALLATION

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.

Figure 36: Casing installed

NOTICE

Refer to the submittal package for specic installation

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.

Figure 38: Louvers and supports

Installing inlet louvers

1. Pick up the inlet louver by holding the louver pattern.

2. Angle the inlet louver to place the top end into the

inlet louver space and slide it all the way up under the

squared inlet louver front supports.

Figure 39: Angling the louver

3. While the inlet louver is slid as far up as it can go into

the inlet louver opening, put the bottom of the inlet

louver into place.

4. Set the inlet louver down so that it rests in the bottom

of the inlet louver opening.

Figure 40: Setting the louver

Removing inlet louvers

1. Grab the inlet louver pattern.

2. Slide the inlet louver straight up to release the bottom

of the inlet louver from the inlet louver opening.

Figure 41: Detaching the louver

3. Pull the bottom of the inlet louver out to remove it.

4. Slide the inlet louver down to release the top of the

inlet louver from the inlet louver front supports.
