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 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.
