SERVICING INSTRUCTIONS

Maintenance on evaporative coolers is minimal,
but very important to the proper operation and
effectiveness of your cooler. Periodic inspection
of the cooler's interior will reduce the potential for
substandard cooling due to insuf cient or uneven
water distribution.
NOTE: For general maintenance purposes, the unit
may be rapidly drained of water by removing the
over ow tting from the bottom of the unit. This is not
adequate draining for winterization (see procedures
under Winterization section.)

Annual Maintenance

(May be Needed More Often in Areas with Hard Water)
Cleaning
WARNING: Disconnect from electrical power and turn
unit off during all maintenance. Turn water supply off
before removing back for cleaning or maintenance.
CAUTION: In order to maintain UV resistance, do not
use abrasive cleaners on the exterior of the cooler
body.

2. Inspect pads in place. Remove media pads from back
guard by unscrewing the media peg clips. Be careful not
to chip or damage the media while removing. Visually
inspect both sides of media pads. Look for blockage,
mineral build-up or mildew growth, breakage or other
anomalies.
3. Wash pads with a garden hose. Do not use a pressure
washer.
4. Check water distributor for blockage or excessive buildup
of dust.
5. Set media in a safe place until all maintenance is complete.
6. Wash out reservoir thoroughly using a soft bristle brush.
Use plenty of water to remove algae growth. Clean areas
around pump, strainer and oat to ensure no algae
growth remains.
CAUTION: Do not use harsh chemicals (like chlorine
bleach) to clean the interior portions of the cooler.
7. Rinse thoroughly after using any cleaning solutions on
the interior or exterior of the unit.
