4.Clean coil using a commercial coil cleaner or dishwasher detergent in a pressurized spray canister. Wash both sides of coil and flush with clean water. For best results, back-flush toward return-air section to remove foreign material. Flush condensate pan after completion.

5.Reinstall economizer and filters.

6.Reconnect wiring.

7.Replace access panels.

Condenser Coil

Inspect coil monthly. Clean condenser coil annually, and as required by location and outdoor air conditions.

One-Row Coil

Wash coil with commercial coil cleaner. It is not necessary to remove top panel.

2-Row Coils

Clean coil as follows:

1.Turn off unit power and tag disconnect.

2.Remove top panel screws on condenser end of unit.

3.Remove condenser coil corner post. (See Fig. 45.) To hold top panel open, place coil corner post between top panel and center post. (See Fig. 46.)

4.Remove device holding coil sections together at return end of condenser coil. Carefully separate the outer coil section 3 to 4 in. from the inner coil section. (See Fig. 47.)

5.Use a water hose or other suitable equipment to flush down between the 2 coil sections to remove dirt and debris. Clean the outer surfaces with a stiff brush in the normal manner.

6.Secure the sections together. Reposition the outer coil section and remove the coil corner post from between the top panel and center post. Install the coil corner and center posts. Replace all screws.

Condensate Drain

Check and clean each year at the start of the cooling season. In winter, keep the drain dry or protect it against freeze-up.

Filters

Clean or replace at the start of each heating and cooling season, or more often if operating conditions require it. Replacement filters must be the same dimensions as the original filters.

Outdoor-Air Inlet Screen

Clean the screen with steam or hot water and a mild detergent. Do not use disposable filters in place of screens.

Step 2 —Lubrication

Compressor

The compressor is charged with the correct amount of oil at the factory.

Fan Motor Bearings

Fan motor bearings are permanently lubricated. No further lubrication is required. No lubrication of condenser-fan or evaporator-fan motors is required.

Evaporator Fan Belt Adjustment

Inspect evaporator fan belt for wear, proper belt tension, and pulley alignment as conditions require or at the beginning of each heating and air conditioning season. Refer to Step 7 - Adjust Evaporator Fan Speed for adjustment and alignment procedures.
