HOT GAS SOLENOID VALVE
NOTE: Valves that have nylon seats must be disassembled
before soldering.
Removal
1. Remove the refrigerant charge.
2. Remove the coil and disassemble the valve.
3. Unsolder the hot gas lines from the valve, and remove
the valve from the unit.
CAUTION: Use a heat sink to prevent
damaging the valve.
