120VAC GROUNDING INSTRUCTIONS

This appliance must be grounded. If it should electrically malfunction, 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 plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

DANGER!

• Improper connection of the equipment-grounding conductor can result in a risk of electric shock. Check with a qualifi ed 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 fi t the outlet, have a proper outlet installed by a qualifi ed electrician.
• This appliance is for use on a nominal 120-volt circuit, and has a grounding plug that looks like the plug illustrated in Figure 1 below. A temporary adapter illustrated in Figures 2 and 3 may be used to connect this plug to a 2-pole receptacle as shown in Figure 2 if a properly grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet (Figure 1) can be installed by a qualifi ed electrician. The green-colored rigid ear, tab, or the like extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adapter is used, it must be held in place by a metal screw. Grounding adapters are not approved for use in Canada.
• Replace the plug if the grounding pin is damaged or broken.
• The Green (or Green/Yellow) wire in the cord is the grounding wire. When replacing a plug, this wire must be attached to the grounding pin only.
• Extension cords connected to this machine should be 12 gauge, three-wire cords with three-prong plugs and outlets. DO NOT use extension cords more than 50 feet (15 m) long.

KNOW YOUR MACHINE DESCRIPTIONS

1. Operator Handle Operator holds onto this handle to move the machine from one location to another.
2. Solution Tank Lid This lid screws off so the tank can be fi lled. The solution fi ll hose is tethered to the lid, and hangs inside the arm of the Operator Handle.
3. Tools & Accessories Various accessories can be stored on the machine.
4. Basket This lift-off carrying basket sits on top of the round lid on the Recovery tank.
5. Recovery Hose Waste water is picked-up through this hose.
6. Chemical Container Holders Two molded-in bottle holders for chemical jugs.
7. Spray Hose This hose delivers water from the machine to the cleaning tool.
8. Drain Hose This hose is used to empty the recovery tank. NOTE: hold the end of the hose above the water level in the tank to avoid sudden, uncontrolled fl ow of waste water when you remove the cap, then lower the hose slowly to control the rate of discharge.
9. Switch Plate The machine’s on/off switches for the vacuum and for the pump are located here and this is where the valve to change chemical feeds is located.
10. Castors and Wheels Castors pivot for ease of steering, and large back wheels make it easy to roll the machine from location to location. Power Cord (11): The 25 ft. power cord connects to a power cord pigtail on the rear of the machine.

KNOW YOUR SWITCH PLATE

• Vacuum Switch (A): turns on the vacuum motor.
• Chemical Valve (B): switches between the two chemical containers. When the selector is pointed straight down, the valve is off and neither chemical is selected. When the selector is pointed directly towards one or the other symbols, that chemical is selected.
• Solution Pump Switch (C): turns on the solution pump.
• Quick Connect (D ): this is where solution comes out of the machine and the attachment point for the solution hose.

METERING TIPS

The chemical metering tips allow you to select the ratio of chemical to water, as the water fl ows out of the machine. Insert the correct metering tip for the desired mixture into the chemical siphon tube.

OPERATION

1. Insert the appropriate metering tips into the chemical feed lines (see illustration, page 5).

2. Fill the holding tank with warm water (not exceeding 120 °F). Do not add any chemical to the tank.

3. Prepare the area for cleaning by emptying waste receptacles, clearing debris, removing paper products, blowing out vents, and sweeping fl oors.

4. Connect the 25 ft power cord (11) to the pig-tail on the rear of the machine. Test the GFCI on the power cord before each use. Plug the GFCI protected power cord into an outlet.

5. PRIME THE PUMP: Attach the priming hose to the outlet quick disconnect (D) and place the open end of the hose into the recovery tank. Turn on the pump and let it run until the pump is completely primed (no visible air in the water stream). Turn the pump off.
   NOTE: prime the machine before you place the chemical feed tubes into chemical containers.

6. Disconnect the priming hose and attach the solution hose (7) to the quick disconnect (D).

7. Attach the spray gun to the other end of the solution line.

8. Place chemicals in the molded-in chemical bottle containers (6) on the rear of the machine. Insert one of the feed lines into one of the chemical containers. Secure the line by screwing on the cap. The chemical will feed from which ever container the selector valve (B) on the switch plate is turned towards and when the gun is used in the low pressure setting. Use chemicals with a pH of between 4 and 12. Never add chemicals to the clean water tank.

9. Set the spray gun (E) to low pressure by sliding the pressure selector forward (low pressure = forward; high pressure = back).

10. Turn on the pump switch (C) (push button) and spray through the gun for a few seconds to fi ll the line with solution.

11. Apply the chemical to the walls and fi xtures from the bottom up. Spray the fl oor last as you work your way out of the room.

12. Allow the chemical to work for the proper amount of dwell time, according to the chemical manufacturer’s directions. Agitate heavily soiled areas with a scrub brush.

13. Turn off the chemical injector valve by turning the selector (B) to the down position.

14. Set the spray gun (E) to high pressure and rinse the area from the top down.

15. Connect the recovery hose (5), attach the squeegee (F), and turn on the vacuum (A) (rocker switch).

16. Squeegee off the mirrors, pick up the liquid off the fl oor with the fl oor tool. If you have the optional blow dry hose, use it to dry the fi xtures.

17. Drain the recovered water into a utility sink or toilet. NOTE: Keep the top of the drain hose (8) higher than the water level in the tank to avoid uncontrolled discharge of water when you open the cap on the hose.

    • CAUTION
    • To avoid vacuum motor damage, always use a defoamer any time foam is present.
    • Before you turn on the vacuum always make sure the fi lter screen on the ball fl oat is clean and that the ball can travel freely.
    • RE-PRIMING THE PUMP
      If the pump looses prime between jobs, follow the instructions to PRIME THE PUMP, above. If that doesn’t get water fl owing, put the priming hose into the vacuum inlet hose barb and cover the rest of the space around the priming hose with your hand. Turn on the vacuum (with the pump also running) and let the suction of the vacuum assist in getting water into the pump.

MAINTENANCE

1. Use only approved chemicals at the recommended mix ratios. All chemicals should be added through the feed system and NOT added directly to the water in the solution tank to prevent possible damage to the pump, seals, or other components.
2. For optimum performance, fl ush the Chemical Feed lines after every job by replacing the chemical containers with containers of clear water and spraying through the gun until the fl uid stream is clear. See the Maintenance Schedule, below.
3. The pump seals and/or valves in the high pressure pumps may need to be replaced after about 1000 hours of use, if the pump begins to loose performance or to leak. The pressure regulator valve may need to be when a drop in the spraying pressure at the tool is apparent.
4. If the 4”, clear lid is removed from the top of the base (solution tank), you will need to apply a silicone sealant to the threads when you reinstall the lid to seal for vacuum leaks.

MAINTENANCE SCHEDULE

• Have Clarke check the carbon brushes once a year or after about 500 hours of operation.
