HOW TO REMOVE, CLEAN OR INSTALL A NEW INLET AIR FILTER

RP aluminum washable air filters are designed to provide excellent filtering efficiency with a high dust holding 

capacity and a minimum amount of resistance to air flow. Since 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 right side panel. To access the filter, pull from slot on top cover. The filter 

may now be cleaned or a 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.

CONDENSER AND EVAPORATOR AIR MOVERS

Fan motor requires no maintenance. All bearings, shafts, etc. are lubricated for the life of the motor during 

manufacturing.
If the condenser fan motor (ambient fan) should fail, it is not necessary to remove the air conditioner from 

the cabinet or enclosure to replace the fan. The condenser fan is mounted on its own bulkhead and is easily 

accessible by opening the front cover.

Operation of the air conditioner in areas containing airborne 

caustics or chemicals can rapidly deteriorate filters, condenser 

coils, blowers and motors, etc. Contact Pentair Equipment 

Protection for special recommendations.

CAUTION

REFRIGERANT LOSS

Each air conditioner is thoroughly tested prior to leaving the factory to insure against refrigeration leaks. Shipping 

damage or microscopic leaks not found with sensitive electronic refrigerant leak detection equipment during 

manufacture may require repair or recharging of the system. This work should only be performed by qualified 

professionals, generally available through a local, reputable air conditioning repair or service company.
Refer to the data on the nameplate which specifies the type of refrigerant and the charge size in ounces.
Before recharging, make sure there are no leaks and that the system has been properly evacuated into a deep 

vacuum.
