Pressure Relief Valves
Important Information regarding Pressure Relief Valve
16C807.
◆
Pressure Relief Valve 16C807 can only be used on
the G3 pump. It is not intended for use with any other
products.
The pressure relief valve uses a
pressure adjustment screw (a) to
set the pressure release point. It
is not intended as a way to
relieve pressure during normal
operation, but as a protective
measure in the event there is an
unintended pressure increase in
the system. Do not use this pres
-
sure relief valve as a means of
relieving pressure in day-to-day,
normal cycle operation.
The pressure adjustment screw
will require periodic adjustments.
Whenever the valve is set/adjusted (after the set point is
found) it is important to ensure that the valve is not bot
-
tomed out and there is at least 1/2 turn of adjustment
remaining. This is determined by turning the screw (a)
1/2 turn and then back turning it out again.
NOTE:
Turning adjustment screw (a) clockwise
increases pressure.
