11.Purge system at least 10-minutes with dry nitrogen prior to brazing.

12.Adjust nitrogen flow until a very small amount (less than 1-psi) of nitrogen is flowing through refrigeration system.

13.While nitrogen is slowly flowing through refrigeration system, solder in lower part of suction line assembly into system. STRAINER DRYER, DUAL INLET (item 8) must be installed during soldering operation.

14.Disconnect dry nitrogen from refrigeration system, then clean all flux from brazed joints with cold water.

LEAK CHECK

Leak check system including newly brazed joints. If joint is suspected of a leak, tape envelope made of poly over joint to trap leaking refrigerant. Wait 10-minutes, then use leak detector to check air inside envelope for traces of refrigerant.

DO NOT VENT REFRIGERANT TO ATMOSPHERE

CHARGING

1.Pressurize refrigeration system to saturation with clean dry R-12 refrigerant gas.

2.Exhaust refrigerant and evacuate. If high-vacuum pump is used, evacuate to at least 200-microns (prefer- ably 100-microns) prior to charging.

3.Charge refrigeration system with 10-ounces of clean dry R-12 refrigerant.

ASSEMBLY
