Early model units used
o-rings in the pressure
switch assembly. Make
sure to recover them
during disassembly.
When installing the valve
body make sure ALL of
the screws have been
installed in the valve body
(finger tight) BEFORE
beginning to tighten and
torque the bolts.
Your Valve Body installation may appear slightly different than this one.
Reinstall the components as they were originally on your unit.
