PREPARING THE MACHINE FOR USE
See the diagrams in the “Know Your Machine” section.
1 Inspect the machine, hoses, and cleaning tools for cleanliness and completeness.
2 Screw the Recovery Tank Lid (11) closed. Ensure the drain cap is closed tightly.
3 Pre-spray spots and heavy traffic areas before extracting with the detergent of your choice. Mix the pre-spray according to
the detergent manufacturer’s directions.
4 Fill the solution tank with clear water (12 gal. / 45.5 L capacity). If desired, add a detergent or rinse of your choice (we
recommend a CRI approved detergent). If you choose to add a detergent to the solution tank, be sure to mix well, and
always follow the use & dilution instructions on the detergent label. Only use a detergent with a pH between 5 and
10. Although this machine is designed to supply instant hot water, the addition of warm water to the solution tank would
increase heater efficiency. Never use water above 130º F/54º C in the solution tank.
CAUTION!
Use low-sudsing, liquid detergents designed for carpet extraction.
OPERATING THE MACHINE
See the diagrams on page A-14.
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 difficult 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 fill 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 fluid entering the Recovery Tank Lid (11) . If there is a large amount of suds in the recovery tank, add a
defoamer chemical (SERVPRO Defoamer item #151) to the recovery tank.
CAUTION!
• Empty the recovery tank before the fluid or foam enters the vacuum motor.
• If foam or liquid escapes from the machine, switch off immediately.
