OPERATION

1  Inspect the machine, hoses, and cleaning tools for cleanliness and completeness.
2  Fill the solution tank with water.  Using warm water may be a bene

fi

 t in cleaning effectiveness, but do not use hot water 

above (130 °F/54 °C) in the tank.

3  Plug in the power cords.  Do not connect both cords to the same outlet; the green, circuit locator light 

(4)

 on the switch 

plate should light up.  If the locator light does not come on, try different outlets with one of the cords until it does.  If 
you are certain the cords are on separate circuits, but the green light still does light up, turn the Bypass switch 

(3)

 on.  

CAUTION

: using the Bypass switch when the cords are on the same circuit may cause the circuit breaker in the wall to 

trip.  

NOTE

: the receptacle on the left (viewed from behind the machine) powers the heater.

4  Add liquid cleaning solution, with a pH of between 6 and 9, to the solution tank.
5  Attach the spray hose to the solution quick disconnect and the vacuum hose to the hose barb on the recovery tank.  Pull 

the hoses off the real to the desired length.  Attach the other ends of the hoses to the cleaning tool.

6  Allow the heat exchanger two minutes to reach operating temperature.
7  Turn on the pump 

(2)

.  Turn on the vacuum 

(1)

.

8  Begin cleaning using the correct hoses and tool.
9  Use defoamer in the recovery tank any time foaming occurs.
10  Monitor the water level in the solution tank.  Do not let the pump run dry.
11  When the solution tank gets low, turn both the pump and the vacuum off, 

fi

 ll the solution tank, empty and clean the 

recovery tank.

12 When 

fi

 nished with the job, remove any unused solution from the solution tank, and run a few gallons of clean water 

through the system.  Drain the recovery tank.

DUAL CORD SENSOR CIRCUIT: 

This unique, patented system is operated by a solid state circuit.  It will inform the operator when the two cords are plugged into separate 
circuits by turning on the green, circuit locator light.  This helps to prevent tripping circuit breakers.

NOTE

:  if the circuit locator light does not illuminate when the cords are plugged in, then both cords are on the same circuit.  Try other 

outlets with one of the cords until you get the locator light to come on.   

NOTE:

 if the bypass, or heat, switch is turned on when both cords are on the same circuit, the breaker may trip.

BYPASS SWITCH:

The bypass switch completely bypasses the circuit locator.  Use this feature when you cannot get the green light to come on and you 
believe that the two cords are on separate circuits.

 CAUTION!

If the bypass switch is on and the two cords are plugged into the same circuit, the breaker may blow.

BALL FLOAT VACUUM SHUT-OFF

Prior to using the machine, always check that the 

fl

 oat 

fi

 lter is clean and the ball can travel freely. When the recovery tank is full, the ball 

fl

 oat will rise and will shut off the vacuum 

fl

 ow to prevent any more water from entering the tank.  When this occurs, turn off the vacuum 

and empty the recovery tank.   

NOTE

:  if foam is present, or if the ball 

fl

 oat is prevented from rising, the 

fl

 oat will not be able to stop the air 

fl

 ow, and the tank may over 

fi

 ll.  

Water damage to the vacuum motors is not covered by warranty.

 CAUTION!

To avoid vacuum motor damage, always use a defoamer any time foam is present.
