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 -300 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. 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 5 and 10 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. 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.

PUMP DIAL (1):
This dial controls motor speed and pump pressure. Adjust the dial clockwise to increase
pressure and counterclockwise to decrease pressure or turn off pump. The pump runs off of
cord #1.
VACUUM SWITCH (2):
This switch will illuminate when the vacuum motor is on. The vacuum motor runs off of cord
#1.
HEAT CONTROL (3):
This dial controls the water temperature. Turn it clockwise to increase water temperature
and counterclockwise to decrease temperature. The heater will operate only if the circuit
locator light (#7) or the bypass switch (#5) is on.
HEAT MODE LIGHT (4):
This light will only illuminate when the heater is heating and will turn off when it reaches
operating temperature. During normal operation, the “MODE” light will be on most of the
time.
BYPASS SWITCH (5):
The bypass switch will illuminate when it is activated and will completely bypass the circuit
locator system. Use this system only when the circuit locator light will not turn on and you
know each cord is on a separate circuit.
CAUTION: WHEN THE BYPASS SWITCH IS ON, THE CIRCUIT BREAKER CAN TRIP IF BOTH
CORDS ARE ON THE SAME CIRCUIT AND THE BYPASS SWITCH IS TURNED ON.
PRESSURE GAUGE (6):
Indicates pump spraying pressure (the air bubble inside the gauge is normal). Do not
operate the machine if the with the needle goes above 325 psi.
CIRCUIT LOCATOR (7):
When this light is on, it indicates that cord #2 (Identified by the red “H” on the back of the
extractor.) is on a separate line from cord #1. Cord #2 supplies voltage to the heater
allowing it to heat to the temperature range indicated by the Heat Control dial (#3) on the
switch plate.

SET-UP and OPERATION:
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 to the holding tank would increase heater
efficiency. Never use water above 130º F/54º C in the solution tank.
1. Plug in cord #1. (This cord runs the pump and vacuum). Attach the priming hose to the machine and place
the open end into the tank (see Fig. #1)
2. Turn on the pump (turn pump pressure dial all the way clockwise) and let it run until the pump is fully
primed (approximately 30 seconds to 1 minute - older pumps may take longer). Turn off the pump and
disconnect the priming hose. Attach the cleaning hose and tool.
3. Turn on the pump and spray through the cleaning tool for a few seconds to fill the lines with solution.
4. Plug in cord #2 (indicated by the red “H” on the back of the machine). IF THE GREEN LIGHT ILLUMINATES,
THE HEAT EXCHANGER WILL TURN ON AUTOMATICALLY (SEE NOTE BELOW). Wait until the red mode
light goes out (approximatley 2 minutes) for the heat exchanger to reach operating temperature. You may
now begin cleaning. NOTE: During normal operation, the red light will be on most of the time.
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 (#5) completely bypasses the circuit locator system. Use this feature when you cannot get
the green Locator light (#7) to come on and you believe that the two cords are on separate circuits.
CAUTION: If the bypass switch is on when the two cords are plugged into the same circuit, the
breaker may trip.
AUTO VACUUM SHUTOFF:
When the recovery tank is full, the float system will shut off the vacuum motor and prevent the machine from
overflowing. The float may not work in foam. Always use a defoamer to prevent overflow. Once the vacuum
motor shuts off, the vac switch (#2) must be turned off, the recovery tank emptied, and then the vacuum swtich
turned back on (up position) to get the vacuum motor started again.
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.
PUMP PRESSURE:
Make sure the cleaning tool is spraying when adjusting the pressure, otherwise the pressure reading will be
inaccurate.
FIGURE #1
Priming Hose Float Filter
FIGURE #2: Shows the float and inlet filter. Each
time the recovery tank is emptied, the float should
be checked for hair and dirt that may effect float
operation (float must travel freely). The filter is
removable and must be kept clean.
