EVAP COOLER PUMP INSTALLATION INSTRUCTIONS
WARNING
• DISCONNECT ELECTRICAL POWER TO COOLER BEFORE INSTALLING OR SERVICING PUMP.
• PUMP INSTALLATION MUST COMPLY WITH COOLER MANUFACTURER’S SPECIFICATIONS AND
APPLICABLE ELECTRICAL AND BUILDING CODES.
• USE ONLY IN UPRIGHT POSITION.
• DO NOT USE WITH COOLER WATER RESERVOIRS OVER 4 INCHES IN DEPTH.
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
DISCONNECT POWER TO COOLER AND UNPLUG
COOLER PUMP
1. Rotate pump shaft by hand before the start of
each season to loosen motor rotor.
2. Clean pump cavity when clogged by removing
bottom of baseplate. Do not use screwdriver to
remove baseplate snaps. Reattach baseplate by
following sequence numbers on baseplate
bottom.
3. Discontinue use of pump when motor stops and
starts due to overheating. If pump does not
operate, inspect for faulty cooler switch,
thermostat or for faulty wiring.
4. To winterize cooler pump, remove from cooler
and store in dry place. Do not winterize cooler
using a “plastic” cooler cover.
