PRESSURE WASHER TERMINOLOGY
PSI: Pounds per Square Inch. The unit of measure for water pressure. Also used
for air pressure, hydraulic pressure, etc. Operating at pressures exceeding the
maximum rating could result in damage to the unit and/or severe personalinjury.
GPM: Gallons per Minute. The unit of measure for the flow rate of water.
CU: Cleaning Units. GPM multiplied by PSI equalsCU.
Pressure Wand Assembly: This refers to the gun, wand andnozzle.
Pump: The pump moves the water through the system and delivers it to the
pressure wand assembly. The nozzle creates thepressure.
Bypass Mode: Allows water to re-circulate within the pump when the gun trigger is
not pulled. This feature allows the operator to release the trigger gun and reposition
themselves without having to turn the engine off in between cleaningactions.
NOTICE: Allowing the unit to run for more than two minutes without the gun trigger
being pulled could cause overheating and damage to the pump. Do not let the
pressure washer run for more than two minutes in Bypass Mode. Turn off the engine
and relieve the pressure in the gun during these extendedsituations.

Thermal Relief Valve: When the temperature inside the pump rises too high, this
valve will open and release a gush of water in an effort to lower the temperature
inside the pump. The valve will thenclose.
Pressure Relief Valve: The water heater coils are designed to operate safely
at normal working pressure. The safety pressure relief valve prevents over
pressurization of the high pressure system. Do not modify the pressure relief valve
inanyway.
High Pressure Pump Oil: The preferred oil is SIMPSON®Premium Pump
Crankcase Oil. If this oil is not available, an SAE 15W-40 oil may be used. Change
the pump oil after the first 50hours of operation and every 100 hours thereafter, or
every 3months.
Gasoline Engine Oil (if equipped):
Check engine oil level before each use. Refer to
the
Engine Owner's Manual for correctprocedure.
12V DC Battery (if equipped): The 12V DC battery operates the engine's electrical
start system, after the engine is started the system will charge the battery and operate
the burner. The 12V battery will need to be replaced regularly to ensure consistent
performance.
Recommended battery size: Colbalt, Streamliner use Group 24 battery
/Patriot use U 1battery.
Burner Assembly: A device used to change fuel to heat energy. It is used to heat
the water in the coil assembly and is designed to use a NO. #2 dieselfuel.
BTU (British Thermal Unit): The amount of work or energy it takes to raise the
temperature of one pound of water by one degreeFahrenheit.
Temperature Control: The burner system is equipped with an adjustable
temperature control. Do not set thermostat above 195°F. The burner will shut off
if insufficient water flow through the burner's heater coil causes the outlet water
temperature to be excessive.
Back Flow Preventer: Prevents backflow into a potable watersystem.
WARNING: To reduce the possibility of contamination always protect
against backflow when connected to a potable water system
Pressure Switch: A switch which uses a pressure activated plunger to activate a
microswitch, used to control the fuel solenoid in the burnersystem.
Flow Switch: A switch which responds to changes in water flow, water flow
moves a magnet which ativates a reed or microswitch to control voltage to the fuel
solenoid in the burnersystem.
Chemical Injection System: Mixes cleaners or cleaning solvents with the water to
improve cleaning effectiveness.
High Pressure Hose: Only use a wire braid hose rated for the output pressure and
temperature of the high pressure pump. Additional hose lengths can be added with
quick twist couplers with a minimal loss in pressure of about .5 PSI per foot. Always
inspect hoses for wear and replace if necessary. Avoid kinking or running over the
hose to extend the hoselife.
Hour meter (if equipped): The analog hour meter operates whenever the engine is
running and keeps track of how many hours the unit has beenused.
