High Pressure Wash; Thermal Relief Valve (Trv) - Champion Power Equipment 75520 Owner's Manual & Operating Instructions

OPERATION

High Pressure Wash

CAUTION
Always engage the trigger safety latch when the unit
is not in use .
The trigger safety latch prevents the gun from being
triggered accidentally . Push the latch fully down to
engage it .
CAUTION
The narrow high impact spray can damage some
surfaces .
A wide fan pattern distributes the impact of the water
over a larger area resulting in excellent cleaning action
with reduced risk of surface damage . Clean large surface
areas quickly using a wide fan pattern .

Thermal Relief Valve (TRV)

This pressure washer uses a pump that is equipped
with an automatic thermal relief valve . The thermal
relief valve will automatically open after approximately 2
minutes passing, without the pulling of the gun trigger,
while the engine is running . Running the engine and not
pulling the trigger causes the water temperature inside
the pump to heat up . When the temperature exceeds
140º F (60º C), or after approximately 2 minutes of non-
gun use, the thermal relief valve automatically activates .
When the valve is activated, it opens to allow fresh/cool
water flow into the pump and hot water to escape . As a
result of the valve opening, hot water inside the pump
will spray out through the Thermal Relief Valve . When
the pump cools, the valve automatically closes .
CAUTION
Water leaving the valve and/or gun after the valve
has become activated may be hot . Make sure the
pressure washer is in a location that is not sensitive
to hot water, and has a clearance space around it
of a minimum distance of 3 feet . DO NOT point
the gun at any animal, human, or surface to avoid
any damage and/or injury caused by hot and/or
pressurized water
NOTE
It is recommended that the inlet water temperature
not exceed 104º F (40º C) .
