OPERATION

PRESSURE WASHER TERMINOLOGY

PSI: 

 Pounds per Square Inch.  The unit of measure for

water pressure.  Also used for air pressure, hydraulic
pressure, etc.

GPM: 

 Gallons Per Minute.  The unit of measure for the

flow rate of water through the pressure washer.

CU:

  Cleaning Units.  GPM multiplied by PSI.

Bypass Mode:

  In Bypass Mode, the pump is recircu-

lating water because the trigger of the spray gun is not
pulled.

Chemical Injection: 

 Feeds cleaning agents into the

pump to mix with the pressurized water and help in
cleaning.

Water Supply:  

 All pressure washers must have a

source of water.  The minimum requirements for a
water supply are 20 PSI and 5 gallons per minute.

NOTE: 

 Any supply pressure or delivery rate less than

this will not allow the pressure washer to operate at its
full potential.

OPERATING FEATURES OF YOUR
PRESSURE WASHER

BYPASS MODE

During normal operation water supply is turned on,
engine is running, spray gun trigger is depressed, and
the cold water supply circulates inside the pressure
washer pump allowing pump to maintain a safe
operating temperature.  When you release spray gun
trigger and engine is still running, you are in bypass
mode.

When unit is in bypass mode, water circulating inside
the pump begins to heat up.  If unit is left in bypass
mode for more than two (2) minutes, the water tem-
perature will rise to a dangerous level and damage
internal components of the pump.

If pressure washer is operated without an adequate
water supply or operated for more than two (2) min-
utes without depressing the spray gun trigger, the
pump will overheat and be seriously damaged. Any
damage to pump due to these causes 

will not be

covered under warranty.

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 output of the DAPC pump on your
pressure washer is preset at the factory to achieve
optimum pressure and cleaning.  It is not adjustable.  If
you need to lower the pressure, there are two meth-
ods.

The first method is to back away from the surface
being cleaned.  The farther away you are, the less
pressure is delivered to the surface being cleaned.

The second method is to reduce the speed of the
gasoline engine (RPM).  Slow the engine down and the
water pressure will go down with it.

DO NOT attempt to increase pump pres-
sure.  A higher pressure setting than the
factory set pressure will damage pump.
