To open the valve turn the hand wheel until the valve position says "OPEN". To close the
valve turn the hand wheel the opposite way until the valve position indicator says "CLOSED".
This valve is equipped with an Air Vent/Drain which will allow the air to escape from the valve when the hose is charged.
The Air Vent/Drain is opened by turning the knob counter clockwise and closed by turning it clockwise.
To drain the water out of the valve after use open the Air Vent/Drain. A 1/2” diameter plastic tube may be used to run the
drain behind the pump panel.
To set the relief valve pressure turn the adjusting screw on the relief valve housing until the surface of the screw is even
with the desired pressure. Do not cap or plug discharge opening.

There is a pressure relief valve on the bottom side of the valve. It may be set to any pressure between 50 and 200 p.s.i.. Its
function is to protect the pump and the supply hose from excess pressure. The relief valve may be mounted with its
opening facing the front, back, right or left. A piece of hose or tubing may be mounted on the round spout to direct the
water coming out of the relief valve away from the pump panel. To change the orientation of the relief valve, remove the
four 7/16 bolts on the corners of the relief valve flange, orient the valve the way you want it, and replace the bolts. Use a
drop of thread locking compound on the threads of the bolt to prevent them from coming loose.
PRESSURE RELIEF VALVE PERFORMANCE
The intake elbow swivels 360 degrees to help prevent hose kinks, and make connection of suction lines easier. The intake
can be turned forward or backward to help make connections in tight places if the water supply is in front of or behind the
truck. To turn the elbow, pull the shot pin knob on top of the elbow. The elbow will lock into a detent every 45 degrees.
There is a hole on the side of the elbow that can be used to attach the lanyard or chain of a cap by use of
. The
elbow may be swivelled to any of eight positions by pulling the shot pin knob.
