SET-UP:

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 exceeding 54º C/130º 

F) to the holding tank will increase the effi ciency of the heater.

2. 

Plug in cord #1. Attach the priming hose to the machine (see illustration on previous page). Turn the 

pump on and set the switch to the upholstery setting.  Run the pump until the pump is fully primed, 

then turn off the pump.  Remove the priming hose, and attach the cleaning hoses and tool.

3. 

Turn on the pump, and spray through the cleaning tool for a few seconds to fi ll the lines with solution.

4. 

Plug in cord #2 (identifi ed by a red “H” on the back of the extractor).  Wait 2 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.

BALL FLOAT VAC SHUTOFF:

When the recovery tank is full, the fl oat system will shut off the incoming air fl ow and prevent water from 

entering the vacuum motors.  The fl oat may not work properly if the fl oat fi lter is clogged or if there is foam in 

the tank.

CAUTION:  To avoid vac motor damage, always make sure the fl oat fi lter is clean and the ball 

travels freely before turning on the machine, and use a defoamer whenever foam is present.
