Aerocool Evaporative Window Cooler - Use and Care Manual 5
Cleaning Water Pump & Hose
CAUTION:
Disconnect all electrical power to the cooler
before attempting to install, open, or service your cooler.
CAUTION
: Do not allow pump to fall over and become
submerged; water will damage pump motor.
Clean water pump and hose assembly as follows:
Unplug pump cord, remove
mounting bracket screw and
remove pump from cooler. Shake
gently to remove water.
To prevent breakage, carefully
release the snap-out impeller
cover plate and remove cover
plate from the pump body.
Using a mild detergent solution and a
soft cloth clean deposits from screen,
around impeller and cover plate. Spin
impeller to dislodge any remaining
foreign material.
Remove any foreign material in the hose adapter
(between the pump and hose), or between the hose
and the water distributor assembly.
Rinse and reinstall impeller cover plate.
Reinstall pump and reconnect pump cord.
Draining
Drain the cooler for cleaning or at the end of the season as follows:
Unplug cooler power supply cord from wall receptacle.
Turn off water supply and remove pad frames.
Connect a drain hose to the drain fitting on the bottom of the
reservoir, if not already connected to drain line.
Remove overflow standpipe from the drain fitting.
Drain and clean reservoir. Remove any remaining water with
a rag or sponge.
Touch-Up
The hardness, adhesion and smoothness of the internal and external
finish on your cooler makes it extremely unlikely that scratches or
chipping will occur. In the event that finish damage does occur it
should be promptly repaired by the following procedures:
1.
Sand the area around bare metal spots.
2.
Prime and paint with a quality paint.
Do not use asphalt type cooler undercoat material in water
reservoir.
Undercoat will break free, clogging the pump and
water distributor.
Lubrication
Motor Bearings
Some motors used in Aerocool coolers have ports for lubricating the
motor and are oiled at the factory. If the need for oiling is indicated, see
individual motor nameplate for specific instructions on re-lubricating
the motor. Under normal use, these motors require oiling about every
12 months of operation.
Do Not Over-Oil
.
Blower Shaft Bearings
Blower shaft bearings need periodic lubrication. They should be
checked 20-30 days after initial start-up of operation. The oil cups on
the bearings should be filled with a good grade of SAE 20W or 30W
non-detergent oil when necessary. Under normal use, oiling is
required every three months of operation.
Do Not Over- Oil.
Pump Motor Bearings
The pump motor does not require lubrication.
Changing Cooler Pads
CAUTION:
Disconnect all electrical power to the cooler
before attempting to install, open, or service your cooler.
The condition of your cooler pad should be checked at least once a
year; at the beginning of the season is best. However, your pad may
need to be checked more frequently, depending on local air and water
conditions. For instance, in areas where mineral content of the water
is high or the air is dusty, deposits may build up in the cooler pad,
restricting airflow. Clean or replace pad as follows:
Remove pad assembly from cabinet.
Lay pad frame on smooth, flat surface with pad retainer up.
Observe the location / placement of the pad retainer. Remove
retainer by sliding it out from under the pad frame flange. Carefully
remove and discard old pad.
Using a mild detergent wash dirt and scale from pad frame and
rinse with fresh water. Check slots at top of pad frame to be sure
they are open and clear. Wire brushing is not recommended. If
finish is damaged or rusting is noted, repair area as noted in the
“Touch-Up” section.
Place the slot in the end of the new pad over the bottom flange of
the pad frame and push the pad down against the flange until it
stops. Gently push the top of the pad into the pad frame. Slide the
1” thick pad on top of the large pad already in place. Replace the
pad retainer by sliding the retainer under the pad frame flanges .
Pre-soak pad (this will help with the wetting of the pad on start-up) .
Reinstall pad frame assembly into unit.
Winter Shut Down:
-
Always
drain all of the water out of the cooler and water supply line
when not in use for prolonged periods, and particularly at the end of
the season. Keep the water line disconnected from both the cooler
and the water supply so it does not freeze.
- Disconnect
power from cooler during extended periods of non-use.
REPLACEMENT PARTS
When ordering replacement parts, always refer to the serial and
model number of your cooler. Use the part numbers listed in the
accompanying parts list, as illustrated in the diagrams for your model.
