Keep pressure relief valve clear of obstructions. This may cause
the relief valve to operate prematurely or fail to operate.
If relief valve appears to be damaged remove the appliance it is
installed to from service until the relief valve can be repaired or
replaced.
The relief valve has no field serviceable parts. Never try to repair
this valve unless you are a certified repair person. Improper repair
could result in serious injury and or death.
All working parts are contained inside the body of the relief valve.
The port opening on the relief valve body should be kept clear of
dirt and debris.
The relief valve should be exercised every six months to keep the
internal components clean and to make sure all parts are working
properly.
Adjust the set screw to the lowest available setting, 100 PSI.
Attach a water supply line to the appliance the valve is attached to
and slowly fill the supply line with water and bleed off any trapped
air.
Keep personnel clear of the valve and slowly increase the pressure
to 100 PSI. The relief valve should open and discharge water from
the PRV when set pressure is reached.
If water is not flowing from the relief valve, slowly increase the
pressure to 110 PSI. Check for water flow from the relief valve.
The relief valve should open and discharge water from the PRV.
Allow water to flow freely from the valve to remove dirt and debris.
If no water is flowing from the relief valve, the relief valve will need
service at an AWG Fittings, LLC facility.
