Important Information regarding Pressure Relief
2
Valve 16C807.
1
◆ Pressure Relief Valve 16C807 can only be used on
the G3, G1, or G-Mini Pumps. It is not intended for use
1
with any other products.
1
The pressure relief valve uses a
pressure adjustment screw (a) to
1
set the pressure release point. It
1
is not intended as a way to
relieve pressure during normal
1
operation, but as a protective
measure in the event there is an
1
unintended pressure increase in
the system. Do not use this pres-
1
sure relief valve a means of
relieving pressure in day-to-day,
1
normal cycle operation.
1
The pressure adjustment screw
1
may require periodic adjust-
ments. Whenever the valve is set/adjusted (after the set
point is found) it is important to ensure that the valve is
1
not bottomed out and there is at least 1/2 turn of
adjustment remaining. This is determined by turning the
1
screw (a) 1/2 turn and then back turning it out again.
NOTE: Turning adjustment screw (a) clockwise
1
increases pressure.
NOTE: Each pressure relief valve requires banjo kit p/n
1
571058. (Except 16C807 because the banjo is already
included in Kit 571028.)
