5. 2000W Heater Operation:
To prevent damage to the heater, the heater must have water in it before it is
turned ON. Fill solution tank, prime the pump and connect solution hose and tool before turning
heater ON.
The 2000W heater has two circuits. For maximum heat both circuits must be on. In situations where there is
only one available 20amp circuit, the heater can be operated using only one 1000W circuit so that the second
cord can safely be used on a 15amp circuit.
• The rocker switch on the Left is Heater Circuit #1, drawing power from Cord #1
• The rocker switch on the Right is Heater Circuit #2, drawing power from Cord #2
While the heater allows for maximum operating temperature of approximately 190ºF, the temperature of the
cleaning water delivered to the tool is dependent on two factors:
• The starting temperature of the water: Starting with hotter water will require a smaller temperature
increase from the heater to reach the maximum temperature.
• Flow rate: The lower the flow rate of the water through the heater, the more time the water will be inside
the heater. The water will have more time to be heated and can reach a higher temperature. High water
usage and flow rate will not allow the water enough time to be heated and the temperature of the water
delivered to the tool will be much lower.
The flow rate can be lowered by putting smaller jets in the
cleaning tool and by reducing the amount of time the wand is
sprayed. Taking additional drying stokes without spraying water
between spraying strokes will help increase the potential
temperature rise.
6. Connection of Vacuum Hoses:
The vacuum connection port on the machine can be either a 2" hose
barb or 2" male Flash Cuff. Both are included with your MX3-200H.
The desired connector can be threaded into the vacuum port on the
front of the machine.
A 2" female Flash Cuff 1-1/2" hose adapter is also included to
connect the 1-1/2" vacuum hose to the 2" male Flash Cuff on the
machine.
A 2" hose cuff for 1-1/2" vacuum hose is included to connect the 1-
1/2" vacuum hose to the 2" hose barb on the machine.
With the proper cuff attached to the 25' Vacuum Hose, the 25'
vacuum hose is then connected to the vacuum connection port on
the MX3-200H. The other end with the 1-1/2" cuff is connected to
the cleaning tool.
When ready to begin cleaning, turn both vacuum switches to the ON
position. If connected in series, the MX3-200H can be operated with
only one vacuum for cleaning delicate fabrics. (See Vacuum
Connection instructions on Page 8) In most situations you will turn both vacuum switches ON.
The water temperature in the solution tank cannot exceed 130° ° ° ° F.
