It is imperative that this unit is installed and operated with the designed airflow and electrical supply in

WARNING: DO NOT RAISE VENTILATOR BY THE INTAKE HOOD, FILTER
TRACKS, OR PIPING – USE LIFTING LUGS PROVIDED OR A SLING

Site Preparation

1. Provide clearance around installation site to safely rig and lift equipment into its final position.
Supports must adequately support equipment. Refer to manufacturer’s estimated weights.

2. Consider general service and installation space when locating unit.

3. Do not allow air intake to face prevailing winds. Support unit above ground or at roof level high
enough to prevent precipitation from being drawn into its inlet. The inlet must also be located at
least 10 feet away from any exhaust vents.

Assembly

There are several items shipped
loose with the evaporative coolers.
These items include the drain trap
components, sheet metal screws,
nuts and bolts, screen intakes (for
outdoor installations), equipment
legs (for outdoor installations), and
hanging cradles (option for indoor
applications). Upon unit arrival,
follow the following procedure to
assemble the evaporative cooler:

1. Attach the evaporative
cooler to the ventilator or
duct using the sheet metal
screws and nuts and bolts
included. Ensure that there is a liquid tight seal formed between the evaporative cooler and the
ventilator.

2. Screw the flanges of the intake screen to the unit with the supplied sheet metal screws. (Outdoor
installations only)

3. Fans designed for outdoor installation are provided with adjustable equipment legs. The
adjustable legs should be used to support and level the front end of the evaporative cooler.

Plumbing Connections

There are two field plumbing connections required for proper
evaporative cooler operation. It is recommended that all
plumbing connections be sealed with Teflon tape or pipe
dope. Use care not to contaminate the interior surfaces of
the water lines when plumbing the unit, as small particulate
can clog the orifices of the spray nozzles.

1. The P-Trap drain should be attached underneath the
cooler (hardware is provided and drain is installed).
The trap is important for two reasons. First, it can be
piped to drain in the most convenient area. Second,
it keeps air from being drawn through the drain hole
in the bottom of the pan, impeding drainage.

2. Pipe the main water supply line (50 psi. max.) to
quick seal on the bottom of the unit. Install a strainer
with sediment trap on the water inlet. It is highly

recommended that a water-softener be installed
up-stream of the unit to extend cooling media life
and prevent scale build-up in unit.
