OPERATING THE MACHINE
1 Follow the instructions in the Preparing the Machine for Use section of this manual.
2 Turn off all the switches. Plug the power cords into properly grounded outlets. Do not connect both cords to the same outlet; the green,
Circuit Indicator Light (D) on the switch plate should light up. If the indicator light does not come on, try different outlets until it does. "Do not
connect both cords to the same outlet."
3 Attach the priming hose to the machine and place the open end into the solution tank.
4 Turn ON the solution pump (A) and let it run until the pump is fully primed (approximately 30 seconds to 1 minute). Once the pump is primed,
turn off the pump and remove the priming hose.
5 Connect a solution line to the Solution Hose Quick Disconnect (1). Attach the other end of the solution line to the cleaning tool.
NOTE: If there is pressure built up in the solution lines, it may be diffi cult to connect a solution line to the Quick Disconnect (1). If this
is the case place the Pump Switch (A) into the OFF (O) position. Momentarily turn the Pressure Relief Valve (16) from the green "checkmark"
position to the red "X" position and back again to the green "checkmark" position, this will relieve the pressure to allow a solution line to be
connected to the quick disconnect port.
CAUTION!
Always operate the machine with the Pressure Relief Valve set to the Green "checkmark" position to avoid possible
damage.
6 Connect a vacuum hose to the Vacuum Hose Barb (3). Attach the other end of the vacuum hose to the cleaning tool.
7 To use heated water for cleaning, press the Heat Switch (E) into either the Low Temperature position (I) or the High Temperature position
(II). Wait two minutes for the heat exchanger to reach temperature.
8 Press the Pump Switch (A) to ON (I).
9 Press the Vacuum Switches (B & C) to ON (I). The machine can be used with only one vacuum motor running for less suction i.e.
cleaning upholstery.
10 Spray through your tool a few times to fi ll the lines with solution. Begin cleaning.
11 To adjust the solution spray pressure; rotate the Pressure Adjustment Knob (14) clockwise to increase pressure and counterclockwise to
decrease pressure. The pump spraying pressure will be observable at the Pressure Gauge (15) while spraying. Make sure the cleaning tool
is spraying when adjusting the pressure, otherwise the pressure reading will be inaccurate.
12 Watch the fl uid entering the Recovery Tank Lid (11). If there is a large amount of suds in the recovery tank, add a defoamer chemical to
the recovery tank.
CAUTION!
• Empty the recovery tank before the fl uid or foam enters the vacuum motor.
• If foam or liquid escapes from the machine, switch off immediately.
CAUTION!
Always make sure the fl oat is clean and travels freely before turning on the machine. A fl oat that is stuck will cause the
vacuum motor to suck in water, resulting in vac motor damage.
13 The recovery tank has a Recovery Tank Shutoff Float (10) to block the vacuum system when the recovery tank is full. You can tell when
the fl oat closes by the sudden change in the sound of the vacuum motor. When the fl oat closes, the recovery tank must be emptied. The machine
can continue to dispense solution, but will not pick up water with the fl oat closed.
14 Monitor the water level in the solution tank. Do not let the pump run dry. When the solution tank gets low, turn off the pump and the
vacuum motor(s), refi ll the solution tank with water and the proper ratio of cleaning detergent. Empty the recovery tank and continue cleaning.
15 When the operator has completed the job; vacuum all unused solution from the solution tank into the recovery tank, turn off the pump,
vacuum motor(s) and heat exchanger. Unplug the machine.
16 Push the machine to a designated waste water "DISPOSAL SITE" and empty the recovery tank. To empty, loosen the Velcro strap
retaining the Recovery Tank Drain Hose (4) into its side storage location, then remove the plug (hold the end of the hose above the water level in
the tank to avoid sudden, uncontrolled fl ow of waste water).
17 Follow the instructions in the After Using the Machine section of this manual.
