DO NOT OPERATE MACHINE UNTIL YOU HAVE READ
ALL SECTIONS OF THESE INSTRUCTIONS
IMPROPER USE OF THE MACHINE WILL VOID THE WARRANTY
1. Always use a defoamer when foaming occurs to prevent vacuum motor damage.
2. Keep machine from rain and snow, extremes in temperatures, and store in a
heated location. Use the machine indoors. Do not use outdoors.
3. Do not let the pump run dry.
4. Use approved chemicals only. NO SOLVENTS.
5. Wear gloves or use rags when removing quick disconnects to prevent burns.
6. Never use water above 54º C/130º F n the solution tank.

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 MIRAI 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.
(and be sure to resister your purchase to activate your warranty)

SET-UP and OPERATION:
1. 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 54º C/130º F) to the holding tank would increase heater efficiency.
2. Turn off all switches. Plug in cord #1 (vac and pump).
3. Attach the priming hose to the machine (see illustration on previous page). Turn on the pump and
select the 200 psi setting. Let the pump run until the pump is fully primed, then turn off the pump.
Remove the priming hose.
4. Connect the solution hose and vacuum recovery hose to the machine. Connect the hoses to the
cleaning tool.
2. Select either 200 or 300 psi. Turn on the pump and spray through the cleaning tool for only a few
seconds to fill the lines with solution. Turn the pump off.
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.
4. Begin cleaning.
5. When the job is finished, remove all unused solution, empty and clean the recovery tank, and clean
and dry the hoses and tools.
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 dirty or if there is
foam in the tank. Foam will 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.
