DO NOT OPERATE THE MACHINE UNTIL YOU HAVE READ THIS SECTION.
IMPROPER USE WILL VOID THE WARRANTY.

•Always use a defoamer when foaming occurs to prevent vacuum motor damage.
•Never use water above 130°F (54°C).
•Do not use outdoors or where temperature is below freezing. Protect your machine
from any extremes in temperatures.
•Do not let the pump run dry. Turn the pump off and refill the tank when cleaning solution
gets low.
•Flush the machine with an acid de-scaler regularly (monthly or more often) to prevent
a build-up of minerals or chemicals in the pump and heat systems. Follow the flush
with a clear water rinse to remove any particles and to rinse the acid from the machine.
•Use approved chemicals only. All chemicals should be mixed thoroughly. Liquid
chemicals are recommended to prevent powder buildups.ApH between 6 and 9 is
recommended. The use of high alkaline detergents or strong acids will accelerate the
wear of the pump and seals, and will void the warranty.
•All extension cords must have a rating of at least 12/3 (#12 cord). Extension cords
should be no longer than 50 feet. Replace the plug immediately if the ground prong
becomes damaged or is broken off.

•Do not pull by the cord, use the cord as a handle, close a door on the cord, or pull the cord around sharp
edges or corners. Do not run the machine over the cord. Keep the cord away from heated surfaces.
•Do not unplug by pulling on the cord. To unplug, grasp the plug, not the cord.
•Do not handle the plug, the cord or the machine with wet hands.
•Do not put any object into openings. Do not use with any opening blocked; keep free of dust, lint, hair, and
anything that may reduce air flow.
•Keep loose clothing, hair, fingers, and all parts of body away from openings and moving parts.

•Do not use to pick up flammable or combustible liquids such as gasoline or use in areas where they may
be present.
•Connect to a properly grounded outlet only. See Grounding Instructions.
•Liquid ejected at the spray nozzle could be dangerous as a result of its temperature, pressure or chemical
content.

120VAC GROUNDING INSTRUCTIONS
This machine 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
havinganequipment-groundingconductorandgroundingplug.Theplugmustbepluggedintoanappropriate
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

OPERATION
1Inspect the machine, hoses, and cleaning tools for cleanliness and completeness.
2Fill the Solution Tank with warm water. Using warm water may be a benefit in cleaning
effectiveness, but do not use hot water (above 130°F+/ 54°C) in the tank. Add liquid cleaning
solution with a pH value of between 6 and 9. High pH detergents and/or acid rinses will
accelerate the wear of the seals and will void the warranty.
3Plug in the power cords. Do not connect both cords to the same outlet. If you are certain the
cords are on separate circuits, turn the Heat switch on. CAUTION: using the Heat switch
when the cords are on the same circuit may cause the circuit breaker in the wall to trip.
NOTE: the cord with the red label “H” at the cord retainer supplies power to the heater. The
other cord powers the vacuum, pump, and cooling fan.
4Attach the spray hose to the solution quick disconnect on the front of the machine and attach
the vacuum hose to the hose barb on the recovery tank. Attach the other ends of the hoses to
the cleaningtool.
5Allow the heat exchanger two minutes to reach operating temperature.
6Turn the pump on. Turn the vacuum on. NOTE: the pump has a built in pressure switch; the
pump runs only when you are spraying.
7Begin cleaning using the correct hoses and tool.
8Use defoamer in the recovery tank any time foaming occurs.
9Monitor the water level in the solution tank. Do not let the pump run dry.
10 When the solution tank gets low, turn off the pump, fill the solution tank, empty and clean the
recovery tank.
11 When finished with the job, remove any unused solution from the solution tank, and run a few
gallons of clean water through the system to rinse out any detergent.
BALL FLOAT VACUUM SHUT-OFF
Prior to using the machine, always check that the float filter is clean and the ball can travel freely.
When the recovery tank is full, the ball float will rise and will shut off the vacuum flow to prevent any
more water from entering the tank. Turn off the vacuum, and empty the recovery tank.
NOTE: if foam is present or if the ball float is prevented from rising, the float will not be able to stop
the air flow, and the tank may over fill.
CAUTION!
To avoid vacuum motor damage, always make sure the float filter is clean and the ball can travel
freely prior to using the machine. And always use a defoamer when foaming occurs.
