2. Install the fan inlet ring (27) and secure with three screws (25) and flat washers (26).

3. Carefully place the condenser fan housing (20) in the unit by rotating the housing 90 degrees counterclockwise and

slide into place.

4. Secure the condenser fan housing (20) to the unit with five attaching screws (24).

CAUTION

Refrigeration tubing is delicate and may break if not handled properly. Use caution when

handling the refrigeration tubing.

5. Secure the clamp and tubing (23) to the fan housing (20) with the screw (21) and lock washer (22).

6. Secure two charging valves (18) and pressure relief valves (19) to the condenser fan housing (20) with three loop

clamps (17), screws (14), flat washers (16), and lock washers (15).

7. Slide the motor shaft extension (5) into the hub of the fan impeller (6) and secure it with the setscrew (8).

NOTE

When motor mounting bulbs are up snug, tighten one full turn on each of the four bolts to

compress the grommets.

8. Insert four bushings (12) and grommets (13) into four motor mounting holes and attach the motor (7) to the

mounting plate (3). Secure in place with eight flat washers (11), four lock washers (10), and four cap screws (9).

9. Carefully place the motor (7) and mounting plate (3) down into the unit and align the holes in the mounting plate

with those in the unit.

11. Slide the shaft motor extension (5) onto the motor shaft and secure with two setscrews (4).

12. Spin the fan by hand and check for equal clearance between the fan inlet ring (27) and the outer edges of the fan (6).

Adjust the mounting plate as necessary.

13. Tighten the cap screws (1) in the motor mounting plate (3). Ensure the fan (6) rotates freely and has adequate

clearance to the fan inlet ring (27).

14. Connect the P4, P5, P6, P8, and P9 connector plugs.

15. Secure the cable and harness with new plastic tie-down straps or lacing cords.
