GENERAL DESCRIPTION

The Fluid Cooler units are designed for cooling fluids such as 40%
Ethylene Glycol. These units are for remote use and use direct
drive, permanently lubricated fan motors. Each module is sepa­rated by a baffle to prevent air bypass. The basic unit is completely
factory wired to its electrical junction panel. Provisions are pro­vided for terminal block wiring of main power, as well as, optional
accessories. Please read the instructions carefully before starting
the installation.

INSPECTION

Inspect the unit to make sure there is no shipping damage before
beginning the installation. If damages are found it should be
reported to the carrier.

FIGURE 1

MOUNTING

Models 005 through 026, can be mounted for either horizontal or
vertical air flow. Refer to Figure 1 for leg assembly mounting for
horizontal and vertical air flow units respectively. The unit should
be mounted onto a level base or frame that is strong enough to
sustain the unit's weight plus its operating charge. The base or
frame and necessary hardware for securing the unit is the
responsibility of the installing contractor. All mounting holes
provided must be used. Unrestricted air flow and unit accessibility
for service are prime concerns in locating these fluid coolers.

LEG ASSEMBLY FOR VERTICAL AIR FLOW

INSTALLATION

1. Remove bolts securing condenser skid.

2. Remove leg extensions (#1) by removing four 5/16" x
3-1/2" bolts.

3. Install as shown in dotted lines with same four bolts.

4. Install mounting angle (#2) as shown (dotted lines) with
four 1-20 x 3/4" bolts provided.

5. Condenser can be hoisted by the 1-1/2" holes in leg
assemblies.

LEG ASSEMBLY FOR HORIZONTAL AIR

FLOW INSTALLATION

1. Remove bolts securing condenser skid.

2. Remove piece (#1) and attach to rear of bottom leg at
"A" to complete mounting base. Piece (#2) is not
required in the horizontal discharge application and
may be discarded.

3. Condenser can be hoisted by the 1-1/2" holes in leg
assemblies.

4. Attach unit to base using mounting holes on leg exten­sions at "B".

6. Attach condenser to base using 7/8" diameter holes in
the base angle.

SPACE & LOCATION REQUIREMENTS

Walls or Obstructions

The unit should be located so that air may circulate
freely and not be recirculated. For proper air flow and
access all sides of the unit should be a minimum of “W”
away from any wall or obstruction. It is preferred that
this distance be increased whenever possible. Care
should be taken to see that ample room is left for
maintenance work through access doors and panels.
Overhead obstructions are not permitted. When the unit
is in an area where it is enclosed by three walls the unit
must be installed as indicated for units in a pit.

Multiple Units

Units in Pits

The top of the unit should be level with the top of
the pit, and side distance increased to “2W”.

If the top of the unit is not level with the top of pit,
discharge cones or stacks must be used to raise
discharge air to the top of the pit. This is a minimum
requirement.

For units placed side by side, the minimum
distance between units is the width of the largest unit. If
units are placed end to end, the minimum distance
between units is 4 feet.

Decorative Fences

* “W” = Total width of the fluid cooler.

HEATCRAFT REFRIGERATION PRODUCTS

Fences must have 50% free area, with 1 foot
undercut, a “W” minimum clearance, and must not
exceed the top of unit. If these requirements are not
met, unit must be installed as indicated for “Units in
pits”.
