2. Test the unit for proper functioning
a. To test the switch assembly, set the head assembly in a vise and make sure that
the switch housing is on the same 45 degree angle as if it were mounted on the
boiler piping.
b. Attach an ohm meter to the common and normally open switch contact and
manually move the float up and down and verify the switch operates on both
directions. The meter should indicate continuity only when the switch is operated
in the closed position.
c. Then, move the ohm meter terminal from the normally open terminal to the
normally closed terminal and repeat the test. The meter should indicate an open
circuit only when the switch is in the open position.
3. If the unit fails to test properly, contact Clark-Reliance for further instructions to adjust
the switch mechanism or to obtain authorization to return the unit for factory inspection.
If the switch tests OK, return unit to service.
4. Reassemble the unit. Reinstall the Switch head assembly onto the body with a new C1-
3 gasket and apply a Teflon based sealant to both sides of the gasket. Lubricate the
bolts with a Nickel based high temperature lubricant and torque the 4 or 6 bolts to 70
FT-LB, in 1/3 increments.
