HEATING WATER
CAUTION
Circulate only clean water through the water heater. Do not circulate slurry or any other mixture through
the water heater. Do not use the heater when metering fluids into the pump from the prime-detergent tank.
The updated heater unit burns JP-8 or diesel fuel only. This fuel is drawn from fuel tank on pump unit.
Using the wrong fuel could damage the equipment.
To prevent damage to water heater, be sure that water is flowing through heater unit prior to turning on the
heater controls. Be sure that VALVE NO. 1 is closed (turned fully clockwise). This ensures that the boiler
is filled with water and that all air is out of the lines prior to heating water.
One end of the power cable passes through the strain relief and is connected inside the control box. Do not
disconnect this end of the power cable. Be careful not to drop electrical connector on power cable or
quick-disconnect on fuel hoses in mud.
NOTE
An operator must be in attendance at all times during operation of the water heater.
Two procedures may be used for heating water depending on if water is to be drawn from a natural source,
heated, and discharged or if water in the tank is to be heated. Generally if water is heated in the tank,
higher water temperatures can be reached since the water can pass through the water heater more than once.
The heater operating instruction plate provides additional heater operating instructions.
