9. Clean the parts to be reused.
Reassembly
1. Install new bellows with O-ring into the
housing.
2. Center the spring on bellows shoulder.
3. Oil the gasket (same type of oil that is used in
the system), install on the body, and place
shims in end cap (use same number as
removed). Tighten end cap in place with vent
hole closest to outlet opening of the valve
body.
4. Install the piston, spring and tighten the castle
nut until firmly seated against the bottom of
the piston.
5. Back off the castle nut, one full turn only.
6. Insert the cotter pin.
.
7. Oil the gasket and install the end cap.
8. Throttling valve will have to be recalibrated
on operating unit. (Refer to “Specifications”
chapter for setting.)
9. Adjust by adding or removing shims under the
spring.
Installation
1. Install the throttling valve using new o-ring
soaked in compressor oil (same type of oil that
is used in the system). Bolt the throttling valve
to the compressor.
2. Connect the suction hose from the throttling
valve to the accumulator tank. Install line
from the compound gauge.
3. Pressurize the system and check for leaks. If
no leaks are found, evacuate the system.
4. Open the refrigeration valves and place the
unit in operation.
