PREVENTIVE MAINTENANCE
AirBoss Spot Coolers are designed to last a long time and to give
maximum performance and reliability with minimum maintenance. To
prolong the life of the unit, regular maintenance must be performed
as specified below:
BLOWER MOTORS
The motors on all units have permanently lubricated bearings. No
oiling is necessary
FILTERS
A clogged filter will cause the unit to operate at greatly reduced
efficiencies. We recommend that the filter be inspected on a regular
bases every six weeks or more often depending on the environment.
The evaporator filter is located behind the return air grille and can be
easily removed and cleaned. The condenser filter is located in the
lower backside of the unit. Remove by loosening one screw holding
retaining clip and pull out. The filters must be washed periodically as
needed by placing them in a dishwasher or soaking them in a
solution of warm water and detergent for 10 minutes. Then rinsing
them clean with hot water and shaking excess moisture from filter.
CONDENSATE PUMP
Condensate pumps come standard on all Size 60 models, and may
be installed as options on size 12, 18, 24 and 36 models. When
servicing pump follow these steps;
1. Make certain that the unit is disconnected from the power source
before attempting to service or remove any component.
2. Be sure the floats move freely. Clean as necessary.
3. Remove the volute and check for obstructions. Clean as needed.
4. Clean the tank with warm water and mild soap when mineral
deposits are visible.
5. Check the inlet and outlet piping. Clean as necessary. Be sure
there are no kinks in the lines that would inhibit flow.
GENERAL

air conditioner will provide long and reliable service. The refrigeration
and electrical circuits of the system should only be serviced by a fully
qualified service technician.
