IMPORTANT SAFETY INSTRUCTIONS
This machine is only suitable for commercial use, for example in hotels, schools, hospitals,
factories, shops and offices other than normal residential housekeeping purposes.
When using any electrical appliance, basic precautions should always be followed, including
the following:
NOTE: Read all instructions before using this machine.
WARNING!
To reduce the risk of fire, electric shock, or injury:
•Do not leave the machine unattended when it is plugged in. Unplug the unit from the
outlet when not in use and before servicing.
•To avoid electric shock, do not expose to rain or snow. Store, and use, indoors.
•Do not allow to be used as a toy. Close attention is necessary when used near
children.
•Use only as described in this manual. Use only the manufacturer’s recommended
attachments.
•Never add water over 130º F/54º C to the solution tank.
•Do not use with damaged cord or plug. If the machine is not working as it should,
has been dropped, damaged, left outdoors or dropped into water, return it to a
service center.
•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. To unplug, grasp the plug, not the cord.
•Do not handle the plug, the cord or the machine with wet hands.
•Extension cords must be 12/3 and no longer than 50 feet. Replace the cord or
unplug immediately if the ground prong becomes damaged.
•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 pick up anything that is burning or smoking, such as cigarettes, matches, or
hot ashes, or any health endangering dusts. Do not use to pick up flammable or
combustible liquids such as gasoline or use in areas where they may be present.
•Turn off all controls before unplugging.
•Use extra care when cleaning on stairs.
•Connect to a properly grounded outlet only.
•Liquid ejected at the spray nozzle could be dangerous as a result of its temperature,
pressure,or chemical content.

INSPECTION:
Carefully unpack and inspect your HHP-310 for shipping damage. Each machine is tested and
inspected before shipping. Any shipping damage incurred is the responsibility of the carrier. You
should notify the carrier immediately if you notice damage to the box or to the machine or parts.
CLEANING SOLUTIONS:
We recommend liquid cleaning chemicals, such as our Magic Fabric Cleaner. Powder chemicals
may be used, but unless mixed very thoroughly they could cause a build-up in the pump, lines,
heat exchanger and/or quick disconnects. Any problem caused by a chemical build-up is not
covered by warranty. Use a neutral cleaner with a pH between 6 and 9 to avoid premature wear
of the pump, seals, and/or other components. Damage caused by the use of strong chemicals is
not covered by the warranty.
MAINTENANCE:
For optimum performance flush the machine with clear water at the end of each working day.
Once a month, minimum, run a flushing compound through the machine to break up any mineral
or chemical build-up that may have formed. U.S. Products’ “X-1500” is recommended. The
vacuum motor, pump motor, and the pump do not require any scheduled maintenance; however,
the motors may require replacement brushes after 1000 - 1500 hours, and the pump and bypass
valve may require rebuild kits after 1000 - 1500 hours, typically (refer to machine part list for
numbers). Clean the body with an all-purpose detergent, and protect it with an automobile
interior polish. Lubricate the wheels, castors, and quick disconnects with an all purpose silicone
spray.
PARTS AND SERVICE:
Repairs, when required, should be performed by your authorized distributor who maintains an
inventory of original replacement parts and accessories. Call the distributor from whom you
purchased this machine if you need parts and service. Be sure to specify the machine model.
Have your serial number handy.
(and be sure to mail your warranty card)

VAC (1) & PUMP (2) SWITCHES:
These switches are powered by cord #1. Switches are on when illuminated.
CARPET/UPHOLSTERY SWITCH (3):
This switch is also powered by cord #1. The carpet setting (down position) is high pressure
(approximately 300 PSI). The upholstery setting (up position) is low pressure (approximately
50 PSI with a K1 or V2 spray tip). NOTE: Switch does not illuminate.
BYPASS SWITCH (4):
Turning on this switch (switch illuminates when on) bypasses the circuit locator.
GREEN CIRCUIT LOCATOR LIGHT (5):
When this light is illuminated, it confirms that the machine is on two separate circuits.
HEAT MODE LIGHT (6):
This light will only illuminate when the heater is heating and will turn off when it reaches
operating temperature. Note: this light will be on most of the time during normal operation.
CAUTION:
THE CIRCUIT BREAKER CAN TRIP IF BOTH CORDS ARE ON THE SAME CIRCUIT AND
THE BYPASS SWITCH IS TURNED ON.

SET-UP:
Fill the holding tank with clear water and the detergent of your choice. Mix well. Although this
machine is designed to supply instant hot water, the addition of warm water (not above
130º F/54º C) to the holding tank would increase heater efficiency.
1. Plug in cord #1 (vac and pump.) Attach the priming hose to the machine (see illustration).
Turn the pump on and set the switch to the upholstery setting. Run until the pump is fully
primed, then turn off the pump. Remove the priming hose and attach the cleaning hoses
and tool.
2. Turn on the pump and spray through the cleaning tool for a few seconds to fill the lines with
solution.
3. Plug in cord #2 (identified by the red “H” on the back of te extractor). IF THE GREEN LIGHT
ILLUMINATES, THE HEAT EXCHANGER WILL TURN ON AUTOMATICALLY (SEE NOTE
BELOW). Wait 2 minutes for the heat exchanger to reach operating temperature. You may
now begin cleaning. It will take about 10 seconds for the initial heat to reach the wand.
NOTE: If the green circuit indicator light does not illuminate when cord #2 is plugged
in, then both cords are on the same circuit. Try other outlets until the light comes on.
See bypass switch section (below) if you are unable to get a green light.
ELECTRIC CIRCUIT LOCATOR:
This unique, patented “smart system”, operated by a solid state circuit, will inform the operator
when the two cords are plugged into separate lines by illuminating the green indicator light. This
helps prevent tripping circuit breakers.
BYPASS SWITCH:
The bypass switch completely bypasses the circuit locator system. Use this feature when you
cannot get the green light to come on and you believe that the two cords are on separate circuits.
CAUTION: If the bypass switch is on and the two cords are plugged into the same
circuit, the breaker may trip.
BALL FLOAT VAC SHUTOFF:
When the recovery tank is full, the float system will shut off the incoming air flow and prevent
water from entering the vacuum motors. The float may not work properly if the float ball cage is
clogged or if there is foam in the tank. Foam may not lift the ball float.
CAUTION: To avoid vac motor damage, always make sure the float cage is clean and
the ball travels freely before turning on the machine, and use a defoamer whenever
foam is present.

TROUBLE SHOOTING:
IF THIS OCCURS CHECK THIS
NO SPRAY
PUMP DOSEN’T RUN
Solution tank is empty.
Clogged spray tip.
Pump not running or not primed.
Valve on wand not operating.
Check the brushes in the pump motor. Replace if necessary. No power to pump.
Test the Motor Speed Control Circuit Board.
Debris plugging cleaning tool or vacuum hose.
Drain gate is not completely closed, or seals are damaged.
Vacuum dome is not seated or is damaged.
No power to motor. Test the switch. Test the Electronic Float. Test the vacuum
motor. Test the Vacuum Circuit Board.
Spraying too long. Try spraying for 12-15 seconds per cycle.
Heat exchanger needs to be flushed.
Wrong tool being used. Too much water passing through. Longer hose or larger
diameter hose, than standard
Heat is not turned on. Either the green light must be on or the bypass switch
must be turned on.
No power in the wall outlet - check to see if the breaker has tripped.
No power to the bypass switch - check wiring for ‘opens.”
No power out of bypass switch, follow troubleshooting steps to isolate the
problem.
