Preventive Maintenance
No preventive maintenance is required other than adhering to the Cleaning Procedure instructions.
Under normal operating conditions a "try lever test" should be performed every two months. Under severe
service conditions, or if corrosion and/or deposits are noticed within the valve body, testing must be
performed more often. A "try lever test" should also be performed at the end of any non-service period.
Hot, high pressure fluid may be discharged from body drain and vent during "try lever" test. Care must be
taken to avoid any bodily contact.
High sound levels may be experienced during "try lever" test. Wear proper safety equipment and exercise
extreme care! Test at, or near, half of the operating pressure by holding the test lever fully open for at least
two seconds to flush the valve seat free of sediment and debris. Then release lever and permit the valve
to snap shut.
If lift lever does not activate, or there is no evidence of discharge, turn off equipment immediately and
contact a licensed contractor or qualified service personnel.
