3 SPEED EVAPORATIVE COOLER
5. Prior to putting your cooler away for winter, always:
a. Drain the tank and wipe it clean.
b. Clean the filter.
c. Re-assemble and run on FAN ONLY for
30 minutes to dry out the filter.
6. Having completed assembly of your cooler, position the
unit with its back to an open window or door. This will allow
fresh air to be drawn through the cooler and exhausted
from the room. Constant air change is essential and part of
the fresh air benefit from evaporative air cooling.
7.
Remember: your cooler has been designed to operate
even if it runs out of water. No damage will be caused
to the pump if cooler runs out of water.
FILLING COOLER OR CONNECTING TO
WATER SUPPLY
Move the cooler to an area where it can be filled.
MANUAL FILL
The cooler can be filled via the front fill door by hose or
bucket. Using the water fill window to monitor water level,
simply depress the fill door and the spring lock will release
and open it. To close, simply push it closed and locked.
AUTO FILL CONNECTIONS
Connect to a water supply using a garden hose or coil hose
(supplied by customer), or a direct water line. (Parts for
direct connection can be obtained at any hardware store.)
Simply attach hose adapter (supplied with cooler) to the
float valve nipple protruding from cooler. Verify water tight
connections by visually examining the hose connection.
CAUTION:
Water inlet pressure should be limited to a maximum 50 PSI.
If valve is overcome, install a pressure reducer (25 PSI) on
nipple first. (It can be obtained at hardware stores in the
Irrigation section.) Hose bib needs only be cracked open
slightly to supply water to float valve, and the cooler only
needs to be about half filled when in auto fill configuration.
The float is already set to that level.

MAINTENANCE
WARNING
: DO NOT remove the back panel with the
cooler running.
NOTE
:
For best operation and long useful life, the
following maintenance and cleaning procedures should
be followed.
CLEANING COOLER AND PADS
At regular intervals, the cooler should be shut down and
disconnected from power supply. The water tank should
be drained of dirty water and sprayed out with fresh
water and refilled. The more you do this, the better it will
work and less calcium will develop on pads and/or other
surfaces. You may spray through the cooling pads to
wash them out and allow water to deposit in the tank to
be drained away. The removable panel and media pad
can be sprayed out on the ground to clean pad. Use light
pressure when spraying pads. NEVER spray pads with
water while cooler is operating and fan is running. This
can cause damage to motor and will void the warranty.
