d. Prepare Flange Surfaces
Scrape and clean flange surface on
control body and control head.
IMPORTANT: Care must be taken not to
damage flange surfaces. Nicks, scrapes
or gouges may cause the flange to leak
when in service.
e. Replace Head Assembly
• Slide flange gasket over float ball.
• Insert head assembly by carefully guiding
float ball into control body.
• Align Gasket and install head bolts.
• Using a torque wrench, tighten head bolts
in an alternating star pattern. Tighten to
14-20 ft•lbs.
• Reconnect wiring to terminal
panels in exactly the same position
as removed.
• Replace switch cover and fasten
with screws. On Model #65, cover and
housing surfaces must be free of grit and
debris for proper seal. On Model #165,
replace the cover gasket.
