INSTALL

CAUTION

Do not contaminate the system when preparing refrigeration tubing for

soldering. Contamination may cause restrictions in the refrigeration

system. Failure to comply may result in damage to the equipment.

1. Prepare refrigerant lines for soldering.

2. Prepare the suction pressure regulator by wrapping it with a wet cloth.

3. Solder the joints and allow them to cool.

4. Reinstall the schrader valve core and the LPCO switch.

5. Leak check, evacuate, and return the system to normal operation.

a. Pump down the low side to a vacuum of 15 in.

b. Stop the unit and observe the low side pressure for at least two minutes. The pressure should

remain below 10-in. Hg of vacuum. If the pressure rises:

(1) To zero and stops, this indicates a low side refrigerant leak to the atmosphere.

(2) To above zero, either refrigerant is boiling out of the oil or there is an internal high side to low

side refrigerant leak.

Remove the jumper wire from the LPCO.

d. Reconnect the weather-tight connector.

e. Back-seat (open) the receiver tank outlet valve.

NOTE

Suction pressure regulator is not preset.

6. Adjust the regulator IAW WP 0029 00.

7. Remove the manifold gauge assembly.

8. Perform system operation check IAW WP 0010 00 PMCS, Item 7.

9. Re-insulate the suction line.

10. Reinstall the condenser support bracket.
