top panel and center post. See Fig. 37.
4. Remove screws securing coil to compressor plate and
compressor access panel.
5. Remove fastener holding coil sections together at re-

outer coil section 3 to 4 in. from the inner coil section.
See Fig. 38.

debris. Clean the outer surfaces with a stiff brush in
the normal manner.

supplied fastener.
8. Reposition the outer coil section and remove the coil
corner post from between the top panel and center

C. Condensate Drain
Check and clean each year at start of cooling season. In win-

or more often if operating conditions require it. Replacement
filters must be same dimensions as original filters.

Fan motor bearings are of the permanently lubricated type.
No further lubrication is required. No lubrication of con-
denser or evaporator fan motors is required.
III. BLOWER BELT ADJUSTMENT
Inspect blower 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 9 — Adjust Evaporator-Fan Speed on page 22
for adjustment and alignment procedures.
Check belt tension at least once each heating or cooling sea-
son or as conditions require. Adjust as required.
