Porter-Cable D22885-011-0, PCV2021 How To Use Wand, Thermal Relief Valve, Pressure Adjustment

Thermal Relief Valve

In an effort to prevent damage, pumps are equipped with a thermal relief valve. This valve will open when the temperature inside the pump rises too high. This valve will then release a gush of water in an effort to lower the temperature inside the pump. Immediately after this occurs, the valve will close.

DO NOT

allow your unit to operate

in bypass mode for more than two minutes at any time. Overheating of pump will cause damage to pump.

Pressure Adjustment

The pressure setting is preset at the factory to achieve optimum pressure and cleaning. If you need to lower the pressure, it can be accomplished by these methods.

1.Back away from the surface to be cleaned. The further away you are, the less the pressure will be on the surface to be cleaned.

2.Reduce the speed of the gasoline engine (RPM). Slow the engine down and the water pressure will go down with it.

Step 3 is for models PCH2627, PCH3030 and PCH3540HR.

3.Adjust the pressure regulator on the pump. Turn the pressure regulator knob counterclockwise to lower pres- sure. Refer to the illustrations to identify your pressure regulator.

Once you have finished using your pressure washer, re- turn the pressure regulator to its original position by turning it clockwise.

DO NOT attempt to increase pump pres-

sure. A higher pressure setting than the factory set pressure may damage pump.

DO NOT try to turn pressure regulator knob

past the built-in stop or damage to pump will result.

HOW TO USE WAND

For Multi-Reg Wands (PCV2021):

Your pressure washer is equipped with a multi-reg wand with both high and low pressure settings. The high pressure setting is for cleaning and rinsing, the low pressure setting is for applying chemicals or cleaning solutions to surfaces.

RISK OF INJECTION OR INJURY TO PERSON.

DO NOT DIRECT DISCHARGE STREAM TOWARD PERSONS.

WHEN USING THE HIGH PRESSURE SETTING,

DO NOT ALLOW THE JET-LIKE SPRAY TO COME IN CONTACT WITH UNPROTECTED SKIN, EYES, OR WITH ANY PETS OR ANI- MALS. SERIOUS INJURY CAN OCCUR.

For high pressure operation, pull back the nozzle of the multi-reg wand as shown.

The nozzle at the end of the multi-reg wand can be rotated to change the high pressure spray pattern from a narrow jet to a 40º fan shape, as shown. Markings have been placed on the nozzle to help you select the spray pattern.

40º fan spray

narrow jet stream

For low pressure operation, extend the nozzle of the multi-reg wand as shown.
