After cleaning and inspecting all parts, reassemble the valve.
1. Install the screen into the bottom cap.
2. Install new stem into the center section.
3. Install new gaskets on both sides of the valve body. Dip gaskets in compressor oil before installing.
4. Install new PTFE seal on the piston.
NOTE: The open side of the seal must face the stem and seat. The closed side of the seal must face the top cap.
5. Install the spring and top cap.
6. Line up the passageways in the cap and body. Failure to line up the holes will result in incorrect operation of the valve.
7. Install bolts and tighten in rotating sequence.
NOTE: Make sure that the stem assembly is located correctly into the hole in the bottom cap.
8. Solder pilot solenoid line and pressurise system with refrigerant to check for leaks.
9. Replace Drier
10. If there are no leaks, evacuate the system and recharge with refrigerant.
11. Operate the unit to check for correct three-way valve operation.
