Operation & Maintenance
Cartridge Removal & Replacement
Before removing a used cartridge for cleaning, have
new casing gasket and sleeve o-rings on hand.
Shut off supplies at stop checks by turning clockwise.
Remove 4 bolts on cartridge bolt flange.
With 2 large bladed screwdrivers, pry evenly on two
opposite sides of bolt flange until cartridge is free to be
removed by hand. Pull out cartridge with a twisting and
turning action, always keeping cartridge on center line.
Leave compensating spring in position at bottom center
of valve body.
Clean cartridge as described in maintenance instruc-
tions.
Replace sleeve o-rings and grease same.
With a twisting and pushing action, replace cartridge
in valve body until bolt flange is firmly against housing
gasket.
While holding cartridge in place, replace bolts and tight-
en. Do not attempt to pull cartridge into position with
bolts—it will damage the valve control mechanism.
Open stops and adjust temperature.
Seasonal Use
When a TempControl is used seasonally (schools, camp-
grounds, golf clubs, etc.) the cartridge must be removed
and thoroughly drained of all water to prevent freeze
damage. The check stops should also be removed to
drain all water from the supply lines and valve body (see
"Cartridge Removal & Replacement"). This will prohibit
damage caused by freezing water.
