CONTROLS:
D. Unloader Valve - Controls the system pressure. The
unloader is pre-set at the factory to a maximum system
pressure. DO NOT adjust this maximum pressure setting.
Turning the unloader knob clockwise past the factory
setting could damage the pump or system components.
If a lower working pressure is required, turn unloader knob
counter-clockwise. The unloader also provides a bypass
for water flow when the gun trigger is released and water
stops spraying.
E. Injector Valve - Allows the operator to add soap, detergent
or chemical to the water only in the low-pressure mode,
i.e. less than 500 PSI. Turn knob clockwise into the body
to lower the flow of detergent. Turn the knob counter-
clockwise to increase the flow of detergent. Do not turn
more than one and a half turns.
F. Thermal Relief - Provides high water temperature
protection for the pump to prevent premature failure of
seals, packings and cups without interruption of flow.
NOZZLE SELECTION
To select the correct nozzle size, determine the pressure (PSI) and
flow (GPM) rating of your pressure washer. This can be found on the
manufacturer’s serial plate or literature. Using the chart for nozzle
requirements below, read across the top to the PSI of your pressure
washer then read down the column to the GPM of your pressure washer.
The correct orifice size is the number in the far left column. Most
manufacturers will imprint an identification code that will tell you the
spray angle and the orifice size. For example, “25040” means the nozzle
has a spray angle of 25° and has a 4.0 size orifice.
