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. For carpet and upholstery cleaning 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.
2. For flood extraction operations set
temperature control to 50°. This temperature
setting energizes the rotary solenoid to hold
the Exhaust Diverter in muffler position.
3. Close the heat bypass valve by turning the
knob clockwise. DO NOT over-tighten.
The heat bypass valve allows you to decrease
the solution temperature manually. Opening the
valve (counter-clockwise) decreases the
temperature by allowing hot water to bypass to
the waste tank.
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.
4. Turn the ignition switch to the START position
while holding the water pump switch to the left
(override position). The engine will start.
For cleaning operation turn pump switch
clockwise to on position. For flood extraction
operations leave switch in off or straight up
position.
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.
5. 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.
