Operating the Optional Lock Release Valve
Use only under conditions in which no water hammer will occur.
The impact of water hammer may damage the product, leading to fluid discharge,
which may cause burns or other injury.
Use on equipment where steam-locking/air binding, which slows the discharge of
condensate and reduces equipment efficiency, tends to occur (cylindrical dryers, air fin
heater, etc.).
1. When the product is shipped from the factory, the element retainer is raised in the
maximum, valve-closed position.
2. Before operating the lock release valve, examine the trap outlet and confirm that the
trap is functioning properly.
3. Operate the lock release valve as follows:
Tools required: flat-head screwdriver
- Open Valve
Insert the screwdriver into the slot on the top of the element retainer and
slowly turn clockwise.
(Do not continue turning the element retainer past the point at which it stops.)
See charts below for steam discharge/air discharge. (Maximums are shown.)
- Close Valve
Insert the screwdriver into the slot on the top of the element retainer and close
by turning counterclockwise.
Raise the element retainer until the snap ring contacts the bottom of the gland
case.
(Do not continue turning the element retainer past the point at which it stops.)
4. If steam should leak from the gland retainer nut or gland case, it can be stopped by
further tightening the gland retainer nut.
(Do not over tighten, otherwise element retainer may seize and become
unworkable.)
