Chapter 5  Maintenance

5.1  Scheduled Maintenance

Industrial Climate Engineering strongly recommends that the air conditioner be serviced a minimum 

of twice a year – once prior to the heating season and once prior to the cooling season.  At this time 

the filters, evaporator coil, condenser coil, the cabinet, and condensate drains should be serviced as 

described below.  Also at this time, the air conditioner should be operated in the cooling and heating 

cycles as described in Chapter 3, Start-Up.  In addition to this seasonal check-out, the air conditioner 

should be maintained as follows:

Air Filter

Replace the air filter whenever it is visibly dirty. Never operate the unit without the filter in place. 

Evaporator

If the evaporator becomes clogged or dirty, it may be cleaned by careful vacuuming or with a com-

mercial evaporator cleaning spray.  DO NOT use a solvent containing bleach, acetone, or flammable 

substances.  Turn off power before cleaning.  Be careful not to wet any of the electrical components.  

Be sure the unit has dried before restarting.

Condenser

Periodically inspect the outdoor condenser coil and the cabinet air reliefs for dirt or obstructions.  Remove  

foreign objects such as leaves, paper, etc. 
If the condenser coil is dirty, it may be washed off with a commercial solvent intended for this purpose.  

TURN OFF POWER BEFORE CLEANING! Be sure that all electrical components are thoroughly dry 

before restoring power. Use a fin comb of the correct spacing to straighten mashed or bent fins.

Cabinet

The cabinet may be cleaned with a sponge and warm, soapy water or a mild detergent.  Do not use 

bleach, abrasive chemicals or harmful solvents. 

Drains

Regularly check the primary and secondary condensate drains. The secondary drain has a stand pipe. An 

obstruction will force water to dump into the middle of the unit and drain out the sides of the CFA1012A 

unit, causing discoloration of the side panels. If discoloration is noted, service the drains.
If a commercial drain solvent is used, flush out the drain pan and system with plenty of fresh water to 

prevent corrosion.

Lubrication

Oiling of the condenser fan motor or the evaporator blower motor is not required.
