5. 1750W 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 hoses before turning heater ON.
While the heater allows for maximum operating temperature of approximately 190ºF or 88°C, 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.
The water temperature in the solution tank cannot exceed 130 °°°° F or 54°C.
• 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 MX500HE. 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 MX500HE. 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 MX500HE
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.
