4 Aerocool Evaporative Window Cooler - Use and Care Manual
GENERAL INSPECTION
Initial Start-up or Annual Inspection
CAUTION:
Disconnect all electrical power to the cooler
before attempting to install, open, or service your cooler.
Before start-up of the cooler for the first time, or at the beginning of
each cooling season, make sure that all required connections,
adjustments, etc. have been made. Verify that:
P
Cooler mounting is level; window and duct are sealed.
P
Power supply cord is correctly routed, safe and secure.
P
Motor, pump, drain, bleed-off, float valve, air outlet grille etc.
are correctly installed and fully functional.
P
Water line securely connected, turned on, & no leaks noted.
P
Float adjusted for proper water level.
P
Pump impeller turns freely and smoothly. If in doubt, remove
impeller cover (see “Cleaning Pump”) and check rotation.
P
Blower wheel, shaft, pulley and motor sheave bolts /
setscrews are tight.
P
Motor sheave / blower pulley alignment is okay; the belt is
correctly tensioned, & blower wheel turns freely.
Start-up Check List
CAUTION
: Never operate cooler with pad frame(s)
and/or air outlet grille removed. This will result in an
overloaded condition and may damage the motor.
To verify and check out the cooler installation on initial or annual start-
up, the following procedure should be followed.
P
Open building exhaust / relief vents (windows, doors, etc.)
P
Plug supply cord into wall receptacle. Switch cooler “ON”.
P
Verify that pump starts and pads are evenly wet.
P
Observe that motor starts and runs.
In case of trouble on any of these steps, refer to the Troubleshooting
Chart on
Cabinet Inspection Checklist
After initial start-up and for a few weeks afterwards, check for and/or
observe the following: Refer to the Troubleshooting Chart on
f
necessary.
P
Leaks from water lines, pad frames, cabinet, etc.
P
Cooler pads: even wetting, no dry streaks.
P
Confirm water level depth setting is correct.
P
Verify full, even flow in water distribution system.
P
Blower wheel / motor rotates freely, no unusual noises.
P
Belt condition / tension / alignment OK.
P
Check motor mounting, cabinet hardware, setscrews on
pulleys, blower wheel are tight

MAINTENANCE SCHEDULE
Regular maintenance and periodic inspection is the key to long and
successful service from your Aerocool cooler. The cooler should
receive major servicing at least once a year, more often if conditions
require (dusty environment, constant use, poor water quality, etc.) For
maximum cooling efficiency, long life and appearance, every two
months during operation the cooler should be inspected and cleaned.
NOTE: Do Not Undercoat the Water Reservoir
Your cooler's water reservoir is finished with our Peblar XT®
appliance-type finish. It is so hard that asphalt-type cooler water pan
under-coatings will not stick to it. Undercoating will break free,
clogging the pump and water distribution system.
NOTE: Do not use cooler cleaners, cooler treatments, anodes or other
chemical additives in this evaporative cooler. Use of any additives or
water treatment other than the furnished bleed-off will void your
warranty and may impair the life of the cooler.
Before starting any maintenance operation, thoroughly read all
operating and maintenance instructions and observe all
cautions and warnings.
Cleaning
CAUTION:
Never wash your cooler cabinet with a
garden hose; water may harm motor and pump or seep
into ductwork. Motors damaged by water are NOT covered
under warranty.
All foreign materials, mineral scale, hard water deposits, dirt, etc.
should be removed from pad frames, water pan and other
components. Your cooler's long lasting finish can be brought to like-
new condition by using warm water and a soft cloth.
NOTE: Avoid using scouring pads, steel wool or wire brushes as these
will damage the finish and encourage corrosion.
Maintenance & Inspection
IMPORTANT:
Before operating cooler at the beginning
of each cooling season, turn blower wheel, cooler motor
and pump motor shafts by hand to make sure they turn
freely. Failure to do so may result in burning out motor.
Periodic inspection of your cooler will enhance the chance for long,
trouble-free service life. For maximum efficiency, every two months
during operation, or any time the cooler is opened, the cooler should
be inspected. Some suggested items to look for:
P
Check for leaks from pad frames, cabinet, etc.
P
Any dry spots or streaks on pads when pump is operating?
P
Are bolts, nuts and set screws still snug?
P
Are the bearings, etc., making any unusual noises?
P
Does the blower wheel turn freely?
P
Is float level set correctly?
P
Is water in the bottom pan clean?
P
Belt condition / tension / alignment OK?
Adjust Belt Tension
Each time you inspect your cooler, be sure to check belt tension on
motor and blower assembly. Check belt condition and replace it if
frays or cracks appear. Check alignment of blower pulley with motor
pulley
(see page 3 for detailed steps).
