3.
Install new gaskets on both sides of the valve body. Dip
gaskets in compressor oil (use same type of oil that is
used in the system) before installing.
4.
Install a new O-ring on the piston, then place the Teflon
seal over the O-ring.
5.
Install the piston on the stem and attach with spring
clip.
NOTE: The Teflon seal will stretch when it is
installed. To prevent this from becoming permanent
(and possibly malfunction), the top cap must be
installed immediately.
6.
Install the spring and top cap.
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 bolts and tighten in rotating sequence.
9.
Solder condenser line to the condenser inlet.
10. Install pilot solenoid line and pressurize system with
refrigerant to check for leaks.
11. If there are no leaks, evacuate the system and recharge
with refrigerant.
12. Run the unit to check for proper three-way valve
operation.
