HOW TO PREPARE THE MACHINE FOR OPERA-
TION
To prepare the machine for operation, follow this procedure:
1.
Connect the vacuum hose to the hose connector on the extractor and to the end of the vacuum tube on the floor tool. See Figure 1 D, E
2. Connect the solution hose to the extractor and the floor tool. To fasten the quick disconnect fitting, slide the knurled collar on the female coupling away from the opening. Push the male coupling into the female coupling. See figure 3 A & B
WARNING: Do not use water that is hotter than
120°F (48°C).
3. Before moving the extractor onto the carpet, put clean hot water into the solution tank.
4. Add a cleaning chemical, such as Clarkare ® Extractor Concentrate, to the hot water. For the correct amount, follow the directions shown on the container.
Set-Up
WARNING: We recommend that you use liquid cleaning chemicals. Powder can damage machine. Powders can cause build-up in the lines, heater, pump, quick disconnects, etc., all of which would void the warranty on those items. A pH of 7-9 is strongly recommended to avoid damage and premature wear to the pump, which would void the warranty.
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 or hot water to the holding tank is beneficial and will reduce pre-heat times.
A. Plug in cord #1 (vac and pump), identified by the red "H" on the end of the cord. Attach the priming hose to the machine (on 300 HV only). Turn the pump on and set the switch to the upholstery setting. Run until the pump is fully primed, then turn off the pump. Remove the priming hose and attach the cleaning hoses and tool.
B. Turn on the pump and spray through the cleaning tool for a few seconds to fill the lines with solution.
B EXT ® 100H, 150H & 300HV
C. Plug in cord #2. The "Locator" light will illuminate when the cords are plugged into separate circuits. Turn the
"Heat" switch on; wait two minutes for the heat exchanger to reach operating temperature. You may now begin cleaning. It will take about 10 seconds for the initial heat to reach the wand. The "Mode" light will turn on when the heat exchanger is actively heating. (See
Figures 5, 6 and 7)
NOTE: If the "Locator" indicator light does not illuminate when cord #2 is plugged in, then both cords are on the same line. Try other outlets until the light comes on.
CAUTION: If both cords are plugged into the same circuit breaker, the breaker may blow when operating with the heater on.
Clarke ® B EXT ® -100, 100H 150H, 300HV Operator's Manual
Page 16
5. If the extractor removes an excess amount of foam from the carpet, add a de-foamer such as Clarkare ®
De-foamer Concentrate to the recovery tank. The amount needed will vary according to the amount of detergent already in the carpet.
CAUTION: To prevent damage, use a water-based defoamer rather than an oil-based de-foamer.
CAUTION: Do not leave the extractor or other cleaning machines or tools on the carpet when not in use. Cleaning solution in the machines and tools can leak onto the carpet and cause light spots or stains.
NOTE: To order Clarkare ® Extractor Concentrate, order part no. 398421. To order Clarkare ® Defoamer, order part no. 398420.
