Installing the Hot Gas Valve:
1. Bend hot gas valve tubing similar to the one being replaced. DO NOT KINK TUBING OR OVERSTRESS TUBING AT VALVE JOINTS.
2. Braze in the new drier assembly and then the capillary tube.
3. APPLY A HEAT SINK OR A DAMP CLOTH ON THE VALVE BODY TO KEEP HEAT AWAY. Be sure to keep heat sink or water from
entering the tubing. Failure to keep the valve body cool will result in a leaky valve.
4. Braze the hot gas valve tube (from the side of the valve) into the tee on the drier assembly.
5. Braze the hot gas valve tube (from the bottom of the valve) into the evaporator bypass tube.
6. Cool the brazed joints with a damp cloth.
7. Remove the heat sink or damp cloth from the valve body.
8. Check for leaks using dry nitrogen gas and a leak detection system.
9. Flush the system and re-charge.
10. Reassemble reversing steps 1 through 9.
