VACUUM HOSE
Connect the vacuum hose to the vacuum inlet
connection at the front of the unit. Connect the other
end of the vacuum hose to the cleaning tool.
STARTING THE UNIT
1. Set the temperature control on the control
panel to the desired cleaning temperature. The
thermostatic temperature control will allow you
to increase or decrease the solution temperature
automatically. Simply turn the control knob to
the desired temperature setting.
Before proceeding, be certain that the control
panel indicators are at the following settings:
Engine – IDLE (Throttle Control In)
Engine Choke – PULL OUT
NOTE: It will not be necessary to pull the choke out
if the engine is already warmed up.
2. Turn the ignition switch to the START position.
The engine will start
NOTE: If your unit fails to build water pressure after
15 seconds, check for adequate water supply. If
necessary, see “Loss of Water Pump Pressure” in
the “Troubleshooting” section of this manual.
3. After starting the engine, push the choke in.
After the engine has warmed up, pull the
throttle all the way out and lock it in the full
throttle position.
Allow adequate time for the unit to warm up
before beginning the cleaning operation,
approximately 5-15 minutes.
PRIMING THE CHEMICAL PUMP
NOTE: It is recommended that the chemical pump
be primed whenever the water pump is ON. This will
eliminate possible pressure fluctuations and water
pump pulsations related to a dry chemical pump.
1. Place the chemical inlet tube and the chemical
prime tube into the chemical container.
NOTE: When placing the chemical inlet tube into
the chemical container, make certain that it stays
fully submerged since the chemical pump will not
function if air is allowed to enter the inlet line. DO
NOT operate the chemical pump without the inlet
strainer properly installed.
a. Turn the chemical selector valve on the control
panel to the PRIME position. The chemical will
then flow from the chemical container through
the chemical prime tube Put the chemical
prime tube into the vacuum inlet on the unit
and seal off the vacuum inlet. The vacuum will
quickly pull chemical from the chemical
container. When the chemical starts to flow,
turn the chemical selector valve to OFF, place
the chemical prime tube back into the
container, and turn the chemical selector valve
back to PRIME to continue the procedure.
b. Once continuous chemical flow without
air bubbles has been achieved, turn the
chemical selector valve from PRIME to
METER. With the cleaning tool open, observe
the flow meter and adjust the chemical
metering valve until the desired rate of
chemical flow is obtained.
