MAINTENANCE
COMPRESSOR
The compressor requires no maintenance. It is hermetically sealed, properly lubricated at the factory and should
provide years of satisfactory operating service.
Should the refrigerant charge be lost, recharging ports (access fittings) on the suction and discharge sides of the
compressor are provided for recharging and/or checking suction and discharge pressures.
Under no circumstances should the access fitting covers be loosened, removed or tampered with.
Breaking of seals on compressor access fittings during warranty period will void warranty on hermetic system.
Recharging ports are provided for the ease and convenience of reputable refrigeration repair service personnel for
recharging the air conditioner.
INLET AIR FILTER
Proper maintenance of the inlet air filter, located behind the front cover, will assure normal operation of the air
conditioner. If filter maintenance is delayed or ignored, the maximum ambient temperatures under which the unit
is designed to operate will be decreased.
If the compressor’s operating temperature increases above designed conditions due to a dirty or clogged
filter (or plugged condenser coil), the air conditioner’s compressor will stop operating due to actuation of the
thermal overload cut-out switch located on the compressor housing. As soon as the compressor temperature
has dropped to within the switch’s cut-in setting, the compressor will restart automatically. However, the above
condition will continue to take place until the filter or coil has been cleaned. It is recommended that power to
the air conditioner be interrupted intentionally when abnormally high compressor operating temperature causes
automatic shut-down of the unit. The above described shutdown is symptomatic of a clogged or dirty filter, thus
causing a reduction in cooling air flow across the surface of the compressor and condenser coil.
Do not run the air conditioner for extended periods of time with the filter removed. Particles of dust, lint, etc., can
plug the fins of the condenser coil which will give the same reaction as a plugged filter. The condenser coil is not
visible through the filter opening, so protect it with a filter.
Continued operation under the above conditions can and will damage and shorten compressor life. The air
conditioner is available with an easily removable inlet filter to facilitate necessary cleaning. There should be no
reason to neglect this necessary maintenance.
HOW TO REMOVE, CLEAN OR INSTALL A NEW INLET AIR FILTER
RP aluminum washable air filters are designed to provide excellent filtering e
翿
ciency with a high dust holding
capacity and a minimum amount of resistance to air flow. Because they are constructed entirely of aluminum
they are lightweight and easy to service. Optimum filter performance is maintained by recoating the filters
after washing with RP Super Filter Coat adhesive. To achieve maximum performance from your air handling
equipment, air filters should be cleaned on a regular basis.
The inlet air filter is located behind the front cover. To access filter, pull ring protruding from slot in bottom of front
cover. The filter may now be cleaned or new filter installed.
Cleaning Instructions:
1. Flush the filter with warm water from the exhaust side to the intake side. DO NOT USE CAUSTICS.
2. After flushing, allow filter to drain. Placing it with a corner down will assure complete drainage.
3. Recoat the filters with RP Super Filter Coat adhesive. When spraying filter do so from both sides
for maximum concentration of adhesive.
