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 SOLUS-500 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.

HEAT CONTROL (1):
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 (#5) or the bypass switch (#6) is on.
HEAT MODE LIGHT (2):
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.
PUMP CONTROL (3):
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. The pump spraying
pressure will be observable at the pressure gauge.
VACUUM SWITCH (4):
This switch will illuminate when the vacuum motors are on.
The vacuum motors run off of cord #1.
CIRCUIT LOCATOR (5):
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 (#1) on the switch plate.
BYPASS SWITCH (6):
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.
NEVER LET YOUR MACHINE OR YOUR WAND FREEZE
CAUTION: THE CIRCUIT BREAKER CAN TRIP IF BOTH
CORDS ARE ON THE SAME CIRCUIT AND THE BYPASS
(heat) SWITCH IS TURNED ON.

SET-UP:
1. Fill the holding tank with clear water and prespray with the detergent of your choice (we recommend a CRI
approved chemical). 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.
2. Turn off all the switches. Plug in cord #1. (This cord runs the pump and vacuum).
3. Attach the priming hose to the machine and place the open end into the tank.
4. 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). Once the pump is primed, turn off the pump and disconnect the priming
hose. Attach the cleaning hose and tool.
IF YOU WANT HEATED SOLUTION:
5. Plug in the the heater cord (identified by “H” on the back of the machine). NOTE: If the green circuit indicator
light does not illuminate when the heater cord 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.
6. Turn the heat knob clockwise to the desired temperature.
7. Turn on the pump and spray through your tool a few times to fill the lines with solution. Begin cleaning.
8. Refill and empty the tanks as necessary.
9. When finished with the job, vacuum all unused solution into the recovery tank, and dump the tank. Clean the
tanks and filters. Clean the tool and hoses. Store the machine in a heated location.
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 (#6) completely bypasses the circuit locator system. Use this feature when you cannot get the green
Locator light (#5) 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 to 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 (#7) 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.
