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.
