120VAC GROUNDING INSTRUCTIONS
This appliance must be grounded. If it should electrically malfunction, grounding provides a path of least resistance for electric current to reduce
the risk of electric shock. This appliance is equipped with a cord having an equipment-grounding conductor and grounding plug. The plug must be
plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
DANGER!
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a qualified
electrician or service person if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug
provided with the appliance. If it will not fit the outlet, have a proper outlet installed by a qualified electrician.
This appliance is for use on a nominal 120-volt circuit, and has a grounding plug that looks like the plug illustrated in Figure 1 below. A temporary
adapter illustrated in Figures 2 and 3 may be used to connect this plug to a 2-pole receptacle as shown in Figure 2 if a properly grounded outlet is
not available. The temporary adapter should be used only until a properly grounded outlet (Figure 1) can be installed by a qualified electrician. The
green-colored rigid ear, tab, or the like extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box
cover. Whenever the adapter is used, it must be held in place by a metal screw. Grounding adapters are not approved for use in Canada.
Replace the plug if the grounding pin is damaged or broken.
The Green (or Green/Yellow) wire in the cord is the grounding wire. When replacing a plug, this wire must be attached to the grounding pin only.
Extension cords connected to this machine should be 12 gauge, three-wire cords with three-prong plugs and outlets. DO NOT use extension cords
more than 50 feet (15 m) long.
WARNING!
• If an extension cord is used, the plug and socket must be of watertight construction.
• Inadequate extension cords can be dangerous.
PLEASE NOTE: FOR NORTH AMERICA ONLY

PREPARING THE MACHINE FOR USE
1Inspect the machine, hoses, and cleaning tools for cleanliness and completeness.
2 Screw the Recovery Tank Lid (1) closed. Ensure the Recovery Tank Drain (3) 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.
4Fill the solution tank (8) with clear water (13 gal. / 49 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
1 Follow the instructions in the Preparing the Machine for Use section of this manual.
2Turn 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 (E) 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.”
3Attach the priming hose to the machine and place the open end into the solution tank.
4Turn ON the solution pump (C) 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. NOTE: If priming is difficult, place the open end of the priming hose into the Vacuum inlet
hose barb, and turn the vacuum on. Use your hand to block the open area in the hose barb. This will allow the pump and the vacuum to work
together to get the water moving.
5 Connect a solution line to the Solution Hose Quick Disconnect (5). Attach the other end of the solution line to the cleaning tool.
6Connect a vacuum hose to the Vacuum Hose Barb (2). Attach the other end of the vacuum hose to the cleaning tool.
7To use heated water for cleaning, press the Heat Switch (D) on. Wait two minutes for the heat exchanger to reach temperature.
8 Press the Pump Switch (C) to ON (I).
9 Press the Vacuum Switch (B) to ON (I).
10 Spray through your tool a few times to fill the lines with solution. Begin cleaning.
11 Note for 400H models only: To adjust the solution spray pressure; rotate the Pressure Adjustment Knob (13) 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 (1). 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 fluid or foam enters the vacuum motor.
• If foam or liquid escapes from the machine, switch off immediately.
CAUTION!
Always make sure the float is clean and travels freely before turning on the machine. A float 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 (7) to block the vacuum system when the recovery tank is full. You can tell when the float
closes by the sudden change in the sound of the vacuum motor. When the float closes, the recovery tank must be emptied. The machine can
continue to dispense solution, but will not pick up water with the float 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, refill 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 and heat exchanger. Unplug the machine.
16 Push the machine to a designated waste water “DISPOSAL SITE” and empty the recovery tank. Drain the recovery tank by opening the drain
gate (3) over a drain or a bucket.
17 Follow the instructions in the After Using the Machine section of this manual.
