INSTALLING PUMP

1. Install a filter screen or basket around pump

base to prevent clogging of pump and water
distribution system, especially in aspen coolers.

2. Mount pump inside cooler using cooler

manufacturer’s original pump mounting bracket.
Secure separate bracket to blower housing or to
blower mounting bar. A pump mounting screw is
provided on top of pump.

3. Securely attach pump hose to pump nozzle and

to water distributor adapter at top of cooler.

4. Connect pump to electrical source:

A. For coolers with a pump receptacle, plug in

pump. CAUTION: Risk of electric shock

—

This pump is supplied with a grounding-type
attachment plug. Be certain it is connected
only to a grounding-type receptacle.

B. For coolers without a pump receptacle,

connect leads to electrical source, in
accordance with cooler manufacturer’s
specifications and all applicable electrical
codes. Leads of replacement pump shall be
terminated at the same point of connection
and in the same manner as the existing
pump.

a. CAUTION

— Risk of fire, electric

shock,

or

injury

to

persons.

Installation requires knowledge of
electrical systems. If not qualified,
do not attempt installation.

b. CAUTION

— Risk of electric shock.

Make grounding connection as
shown in wiring diagram.

5. Secure excess pump cord inside cooler to

prevent cord from touching: a) water in reservoir
or on pads, and b) moving parts such as blower
wheel. CAUTION

— Route pump cord in the

same manner as was done in the original
installation (for example, through clip on blower
mounting bar). Otherwise, if pump cord remains
loose (not taut), then additional cord securing
must be performed.

6. Fill water reservoir to depth recommended by

cooler manufacturer, usually between 2-1/4 to 3
inches deep (or approximately 1/2 inch below
the top of the overflow pipe). Adjust float valve

to shut off at recommended water depth.
Important: Reservoir depth must not exceed 4
inches.

PUMP MAINTENANCE
