After cleaning and inspecting all parts, reassemble the
valve.
1.
Install the screen in the bottom cap.
2.
Install the new stem in the bottom cap.
3.
Install new gaskets on both sides of the seat. Oil the
gaskets in compressor oil before installing.
4.
Use the three-way valve seal installation tool P/N 204-
1008 to install a new seal on the piston. This prevents
the seal from being stretched and damaged.

Place the piston slot on the stem and secure with spring
clip. The open part of the clip should be on the opposite
side of the piston slot.

7.
Line up the passageways in the cap and body. Failure to
line up the holes will result in improper operation of the
valve.
8.
Install the bolts and tighten in rotating sequence.
9.
Install the pilot line and pressurize the system with
refrigerant to check for leaks.
10. If there are no leaks, evacuate the system and recharge
with the proper refrigerant.
11. Run the unit to check for proper three-way valve
operation.
