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.

WARNING:Do not use water that is hotter
than 120°F (48°C).
To clean an area of carpet, follow this procedure:
1. Start the pump for the solution and the motor for the
vacuum on the extractor.
2. Begin at the right-hand corner of the carpet.
3. Hold the floor tool at the angle that gives the best
vacuum seal between the tool and the carpet.
4. Apply pressure to the lever for solution release. Pull
the tool toward you at a slow, steady speed. To
remove as much solution as possible, release the
lever before you stop moving backward. Push tool
away over the same area while moving tool to next
position. (Repeat process)
5. To clean the edge of a room, move the tool along the
baseboard until the edge of all the carpet is cleaned.
6. To clean a small area of carpet, clean the carpet in
sections three feet square. As you make more
passes, repeat one inch of the area already cleaned.
7. To remove more liquid from the carpet, make passes
over the area already cleaned, but do not apply
pressure to the lever for the solution.
Figure 8B
How To Clean A Larger Area Of Carpet See Fig. 8B

1. Begin at the right-hand corner of the carpet.
2. Make a pass halfway along the edge of the carpet.
Pull the tool backward at a steady speed.
3. Move to the edge of the carpet. Make another pass
next to your first pass.
4. As you make more passes, repeat one inch of the
area already cleaned. If you use a power brush tool,
repeat one inch of the area already cleaned by the
brush. Make each pass four inches different in length
to prevent making a line in the center of the carpet.
5. Make more passes until half of the carpet is cleaned.
To remove more liquid from the carpet, make passes
over the area already cleaned, but do not apply
pressure to the lever for the solution.
6. Move to the right-hand corner of the part of the carpet
not yet cleaned.
7. Make a pass halfway along the edge of the carpet.
