Grounding Instructions

THIS PRODUCT IS FOR COMMERCIAL USE ONLY.

Electrical:

In the USA this machine operates on a standard 15 amp 115V, 60 Hz, A.C. power circuit. The amp, hertz, and voltage are listed on the data label found on each machine. Using voltages above or below those indicated on the data label will cause serious damage to the motors.

Extension Cords:

If an extension cord is used, the wire size must be at least one size larger than the power cord on the machine, and must be limited to 50 feet (15.5m) in length.

Grounding Instructions:

This appliance must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This appliance is equipped with a cord having an equipment-grounding conductor and grounding plug. The plug must be inserted into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

This appliance is for use on a nominal 120-volt circuit, and has a grounded plug that looks like the plug in "Fig. A". A temporary adaptor that looks like the adaptor in "Fig. C" may be used to connect this plug to a 2-pole receptacle as shown in "Fig. B", if a properly grounded outlet is not available. The temporary adaptor should be used only until a properly grounded outlet (Fig. A) can be installed by a qualified electrician. The green colored rigid ear, lug, or wire extending from the adaptor must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adaptor is used, it must be held in place by a metal screw.

Grounding Pin Grounded Outlet FIGURE A GROUNDING CONNECTION USING AN ADAPTOR Adaptor Metal Screw FIGURE B Adaptor Tab for Grounding Screw FIGURE C Note: Adaptors are not allowed in Canada.

WARNING:

Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a qualified electrician or service person if you are in doubt as to whether the outlet is properly grounded. Do not modify the plug provided with the appliance - if it will not fit the outlet, have a proper outlet installed by a qualified electrician.

AVERTISSEMENT:

Set-up and Operation

1. Upon removing your new mini-extractor from the box, loosen the latch at back end of the machine that secures the recovery tank to the solution tank. Remove the recovery tank from the solution tank.
2. Pour clean, hot water to the indicated fill line of the solution tank. To avoid possible tank distortion, water temperature must not exceed 140 F (60C).
3. Add a non-foaming cleaning solution concentrate, for use in hot water extractors at the proportions noted on the container (See list below), into solution tank.
4. Place the recovery tank back onto the solution tank and refasten the latch.
5. Plug the power cord into grounded outlet (See GROUNDING INSTRUCTIONS).
6. Connect the vacuum and cleaning tool hoses to the extractor. This unit is equipped with an 1/8" male quick connect for solution hose attachment and a 1" ID vacuum hose hookup. Insure that the female solution hose coupler is securely locked onto the male coupler on the extractor.
7. Turn switch ON. This switch operates both the vacuum motor and the water pump. NOTE: The pump is an oscillating pump and should not be run dry for extended periods of time. This may cause damage to your pump, therefore voiding your warranty.
8. Squeeze the solution lever on the cleaning tool to spray cleaning solution and place the vacuum head on the surface to be cleaned. Normally, chemical is applied on the push stroke while vacuuming is done on the pull stroke. For heavily soiled carpets the hand tool may be used in the scrubbing manner, applying chemical in both the push and pull stroke. Always finish up an area with a vacuum pull stroke.
9. When cleaning, be sure to monitor the level of recovered solution in the recovery tank. When the solution reaches the FULL mark, shut off the extractor, loosen the latches and empty the recovery tank.

NOTE: Dispose of waste in a proper manner which would not violate any Local, State or Federal law.

CAUTION:

Operating vacuum with solution above the FULL mark could draw water directly into the vac motor. This will cause damage to the motor, therefore voiding your warranty.

ATTENTION:

Always Test Upholstery/carpet For Color Fastness In An Inconspicuous Place. Also, To Avoid Prolonged Drying Times, Do Not Spray Too Much Solution In Any One Area.

ATTENTION:

Always use defoamer if foaming occurs. Foam will suspend large particles which may damage vacuum as well as allow liquid into the vacuum motor without activating the float shutoff.

ATTENTION:

To prevent possible disease hazard, before attempting to clean bodily fluids spills, you must kill any viruses, germs or bacteria present in the bodily fluid.

ATTENTION:

*Registered Trademark

Daily Maintenance

Follow same procedure for Shut Down and Storage.

Periodic Maintenance

1. Twice a month, flush a white vinegar solution (one quart vinegar to two gallons water) or anti-browning solution (mixed as directed) through the extractor. This will prevent build-up of alkaline residue in the system.
2. If spray jet becomes clogged, remove the spray tip, wash it thoroughly, and blow dry.

NOTE: Do Not Use Pins, Wire, Etc. To Clean Nozzle As This Could Destroy The Spray Pattern.

1. Apply silicone lubricant to solution nipple.
2. Periodically inspect all hoses, electrical cable and connections on your machine. Frayed or cracked hoses should be repaired or replaced to eliminate vacuum or solution pressure loss. If the cable insulation on the power cord is broken or frayed, repair or replace immediately. Don't take chances with electrical fire or shock.

WARNING:

Before making any adjustments or performing any maintenance to your machine, disconnect the power cord from the electrical source.

▲ AVERTISSEMENT:

Shut Down and Storage

1. Turn Switch OFF. Empty recovery tank completely and rinse several times to remove any dirt or debris that may be left behind.
2. Tip the solution tank over a sink to drain any unused cleaning solution and rinse with clean water to remove any suds left behind by the cleaning chemicals.

NOTE: Dispose of waste in a proper manner which would not violate any Local, State or Federal law

1. Run a small amount of clean water through pump if chemicals were used. This will help insure the life of your pump.
2. Check the spray jet on the cleaning tool for full spray pattern and inspect vac head for any obstructions. Also make sure to clean the filter cap attached to portal cover of any debris that may have been trapped during cleaning.
3. Remove as much moisture from system before storing in cold climates. Excess water may freeze during storage and crack internal components, causing damage to the unit.

WARNING:

Only qualified maintenance personnel are to perform repairs.

AVERTISSEMENT:

1. Turn off all switches and unplug the machine.
2. Unlatch and remove recovery tank.
3. Unfasten screws holding vacuum motor housing to solution tank.
4. Unfasten screws holding pump plate to bottom of solution tank.
5. Remove solution hoses from fittings on pump.
6. Remove pump from brackets and remove fittings and grounding wire.
7. Reverse process to install new replacement pump.

Vacuum Motor Replacement

1. Turn off all switches and unplug machine.
2. Unlatch and remove recovery tank.
3. Unfasten screws holding vacuum motor retainer to vacuum motor housing
4. Lift vacuum motor from vacuum motor housing. Locate the vacuum motor wires and disconnect at the connector.
5. Remove vacuum motor.
6. Reverse process to install vacuum motor replacement.

WARNING: The green ground wire must be attached for safe operation. See wiring diagram.

If armature commutator is grooved, extremely pitted or not concentric, the motor will need to be replaced or sent to a qualified service center.

Important:

These brushes wear quicker as the length shortens due to increased heat. Spring inside brush housing will damage motor if brushes are allowed to wear away completely.

Periodically check the length of the carbon brushes. Replace both carbon brushes when either is less than 3/8" (9.5mm) long.

Troubleshooting

PROBLEM CAUSE SOLUTION
Little or no solution flow C	Clogged spray jet on cleaning tool Remove and clean jets
	Faulty pump Check and replace pump
	Incorrectly attached solution hose Ensure solution hose coupler is securely attached to the coupler on the solution tank
Loss of vacuum/Solution recovery	Incorrectly attached vacuum hose Ensure Vacuum hose is pushed completely onto the recovery tank inlet.
	Obstruction in cleaning tool Inspect for and remove any debris.
	Recovery tank is not securely mounted on the solution tank	Tighten latch on either end of the machine
