Fig. 36 Ð Condenser Coil Cleaning

Two-Row Coils (size 072)

NOTE: Save all screws removed in this section. The screws must be used when reinstalling the equipment.

1.To access 2-row coils, remove screws securing condenser- fan grille to condenser coil top cover. Place grille on top of condenser coil top cover as shown in Fig. 36. It is not necessary to remove the top cover.

2.Remove 3 screws on right side of compressor access panel. Remove one screw securing condenser coil top cover to compressor access panel. Remove lower screw secur- ing condenser coil to compressor mounting plate. See Fig. 11.

3.Remove 4 screws securing control box access cover. Re- move 3 screws (located in front of the control box ac- cess cover) securing condenser coil top cover.

4.Remove screws securing low-voltage access panel. Re- move 2 screws inside the 24-v barrier access panel. Tilt sheet metal (located on left side of the 24-v connec- tions) back 45 degrees.

5.Remove screw securing refrigerant service port access panel.

6.Remove 2 U-clips securing 2-row coils together at hair- pin end.

7.Remove screws securing two corner posts. Remove two corner posts.

8.Use right corner post to prop up right side of con- denser coil top cover. Slide condenser coil partially out of condenser fan housing. See Fig. 37.

9.Use left corner post to prop up left side of condenser coil top cover.

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

11.Use a water hose or other suitable equipment to ¯ush down between the 2 coil section to remove dirt and de- bris. Clean the outer surfaces with a stiff brush in the normal manner.

12.Secure inner and outer coil together with U-clip.

13.Reposition the outer and inner coil section.

14.Reverse the procedure outlined above to reinstall equipment.

II. LUBRICATION

A. Compressors

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

B. Fan-Motor Bearings

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

III. CONDENSER-FAN ADJUSTMENT (Fig. 39)

Shut off unit power supply. Remove condenser-fan assembly (grille, motor, and fan) and loosen fan hub setscrews. Adjust fan height as shown in Fig. 39. Tighten setscrews and re- place condenser-fan assembly.
