II. Lubrication

B. Outdoor Coils

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

Clean 2-row coils as follows:

1.Turn off unit power and tag disconnect.

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

3.Remove outdoor coil corner post. See Fig. 39. To hold top panel open, place coil corner post between top panel and center post. See Fig. 40.

4.Remove device holding coil sections together at return end of outdoor coil. Carefully separate the outer coil section 3 to 4 in. from the inner coil section. See Fig. 41.

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 coil sec- tions, and remove the coil corner post from between the top panel and center post. Install the coil corner post and coil center post, and replace all screws.

C.Condensate Drain

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

D. Filters

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

E. Outdoor-Air Inlet Screen

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

F. Belts

Adjust belt tension and pulley alignment at least twice a year or more frequently as operating conditions require.

A. Compressors

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

B. Fan Motor Bearings

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