Brisa Evaporative Window Cooler - Use and Care Manual

MAINTENANCE SCHEDULE

Regular maintenance and periodic inspection is the key to long and

successful service from your Brisa 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:

Check for leaks from pad frames, cabinet, etc.

Any dry spots or streaks on pads when pump is operating?

page 6 i

Are bolts, nuts and set screws still snug?

Are the bearings, etc., making any unusual noises?

Does the blower wheel turn freely?

Is float level set correctly?

Is water in the bottom pan clean?

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).
