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-310R 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 RECIRCULATION SWITCH (1):
This switch will energize a solenoid that will pump heated
water back into the holding tank in order to pre-heat the
cleaning solution -- up to 125 °F.
NOTE: this switch must be turned off to prime the
pump or to begin the cleaning operation.
CIRCUIT LOCATOR (2):
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 (3):
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.
HEAT INDICATOR LIGHT (4):
When this light is on, it indicates that the heater is turned
on. Once the heater reaches temperature, this light will
go out. Expect this light to be lit most of the time as you
clean.
CARPET UPHOLSTERY SWITCH (5):
This rocker switch activates a solenoid valve - when it is
turned to Upholstery - that allows most of the pump
pressure to recirculate back to the Holding tank This
allows you to clean delicate material at low psi (about 75
psi) When the switch is set to Carpet, the pump operates
without the solenoid and provides about 300 psi to the
cleaning tool. The pump runs off of cord #1. The pump
spraying pressure will be observable at the pressure
gauge. This switch does not light up.
PUMP ON/OFF SWITCH (6):
This switch turns the pump on and off. It will light up
when it is turned on.
VACUUM ON/OFF SWITCH (7):
This switch will illuminate when the vacuum motors are
on. The vacuum motors run off of cord #1.

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 o 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 on, 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.
IF YOU WANT TO PRE-HEAT THE SOLUTION IN THE HOLDING TANK
6. Turn on both the pump and heat recirculation switches. NOTE: this switch will recirculate heated
water back to the holding tank, untili it reaches 125 °F. At that point, the recirculation will
automatically stop. If the temperature of the water in the tank drops below 125 °F, and if the
recirculation switch is still turned ON, the system will begin to recirculate the the water again until
it gets back up to 125 °F. You can choose to let the solution in your holding tank reach 125° or
you can choose to begin cleaning sooner than that.
NOTE: the time that it will take for your solution to reach 125 °F will vary with the temperature of
the solution that you put into the tank, the ambient temperature, the amount of solution in your
tank, etc.
YOU MUST TURN THE HEAT RECIRCULATION SWITCH OFF BEFORE YOU BEGIN
CLEANING, otherwise your pump pressure will be very low.
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. Do NOT freeze.
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 preventoverflow. 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.
