This equipment is to be used by trained firefighting personnel only. Failure to
obtain proper training may result in severe injury or death.
Do not exceed maximum operating pressure. Exceeding the maximum rated
pressure for this appliance may cause malfunction, or failure resulting in severe
injury or death.
Failure of fittings and hoses can result in injury. Use caution not to exceed hose
pressures as stated in NFPA 1961 for the type of hose being used.
Make sure all connections are secure and complete. Failure to ensure proper
connection may result in leaks or cause the devices to become disconnected
under pressure resulting in injury or death.
Open and close all valves slowly. Failure to operate valves slowly may cause
water hammer, which may result in damage or failure of hose, coupling devices,
and appliances leading to injury or death.

Setting the PRV.
Incorrectly setting the pressure relief valve may result in the valve
opening to soon and creating inadequate water flow or to late resulting
in over pressurizing the hose line or appliance. Be sure to test your
setting before placing the unit in service.
If the relief valve operates continually, fails to operate or water leaks
slowly through the relief valve during use, remove from service until
valve can be cleaned, repaired, and the pressure reset.
Inspect for damage or malfunctioning parts. If appliance is damaged
or not functioning remove from service until repairs can be made.
Altering of this device may reduce its operating effectiveness or safety.

The relief valve has 3 settings, 100 PSI, 150 PSI, and 200
PSI.
When the adjustment screw is set flush with the top cover,
the highest vertical setting, the relief valve is set to open at
100 PSI.
When the adjustment screw is set in its middle position, the
top of the screw will be flush with the height of the slot cut in
the top cover. The relief valve will be set to open at 150
PSI.
When the adjustment screw is set all the way down to its
lowest vertical position, where the screw will not go any
lower, the relief valve will be set to 200 PSI
