Outdoor Fans Ð Each fan is supported by a formed- wire mount bolted to the fan deck and covered with a wire guard. The exposed end of the motor shaft is covered with a rubber boot. In case a fan motor must be repaired or re- placed, be sure the rubber boot is put back on when the fan is reinstalled and be sure the fan guard is in place before starting the unit. Figure 14 shows the proper position of the mounted fan. Fan motors have permanently lubricated bearings.

Lubrication

FAN MOTORS have sealed bearings. No provisions are made for lubrication.

COMPRESSOR has its own oil supply. Loss of oil due to a leak in the system should be the only reason for adding oil after the system has been in operation. See Oil Charge section.

Cleaning Coils Ð The coils can be cleaned with a vacuum cleaner, washed out with water, blown out with low-pressure compressed air, or brushed (do not use wire brush). Fan mo- tors are drip-proof but not waterproof.

Clean outdoor coil annually or as required by location or outdoor air conditions. Inspect coil monthly, and clean as required. Fins are not continuous through coil sections; dirt and debris may pass through ®rst section, become trapped between the 2 rows of ®ns (38AE012) or 3 rows of ®ns

(38AE014,016, 38AKS024) and restrict outdoor air¯ow. Use a ¯ashlight to determine if dirt or debris has collected be- tween coil sections. Clean coil as follows:

1.Turn off unit power.

2.Remove screws holding rear corner posts and top cover in place. Pivot top cover up 12 to 18 in. (305 to 457 mm) and support with a rigid support. See Fig. 15.

3.Remove clips securing tube sheets together at the return bend end of the coil. Carefully spread the ends of the coil rows apart by moving the outer sections. See Fig. 16.

4.Using a water hose, or other suitable equipment, ¯ush down between the sections of coil to remove dirt and debris.

5.Clean the remaining surfaces in the normal manner.

6.Reposition outer coil sections.

7.Reinstall clips which secure tube sheets.

8.Replace top cover and rear corner posts.
