OPERATING INSTRUCTIONS
Once your unit has been installed by a qualified serviceman and you have
completed the PRE-OPERATION CHECKLIST, you are ready for operation.
The following steps will help you operate your machine safely.
FLUSHING THE SYSTEM:
1. This unit has a steel coil which, after setting, will cause the water remaining
in the coil from the previous usage to turn brown or black. This water
must be flushed from the system before start-up. This procedure should
be performed without a gun and lance installed.
a. Attach garden hose to machine.
b. Turn on water supply.
c. Run the water for 3-5 minutes.
d. Turn off water supply when clear water is discharged from coil.
CAUTION RISK OF UNIT DAMAGE! BE CERTAIN THE GUN & LANCE
ASSEMBLY ARE NOT CONNECTED TO THE UNIT WHILE
FLUSHING THE SYSTEM.
DEPOSITS TO BE RELEASED FROM THE SYSTEM WHICH
WOULD OBSTRUCT OR DAMAGE THE GUN AND NOZZLE
ASSEMBLY RESULTING IN COSTLY REPAIRS.
HOT WATER OPERATION:
WARNING RISK OF BURN! THE WATER TEMPERATURE COULD
BECOME VERY HOT DURING HOT WATER OPERATION.
CAUTIOUS WHEN ADJUSTING PRESSURE OR CONTROLLING
THE TRIGGER GUN/LANCE ASSEMBLY.
1. Push in the burner switch to turn on the burner. On initial start-up, water
will begin turning hot in approximately 60 seconds and will reach maximum
temperature in approximately 3 minutes, provided the trigger remains
squeezed. The burner will stop firing when the trigger is released.
2. Set thermostat to the desired setting.
At this point, the unit is operating as a hot water heater module. Be certain
to be extremely cautious when adjusting the pressure and controlling the
trigger gun/lance assembly to avoid the possibility of burns.
SHUTDOWN:
1. If the burner switch is still on, turn it off.
2. Squeeze the trigger and discharge the water for a period of three minutes
to cool the heat exchanger and high pressure hose. (Insufficient cool down
period of the high pressure hose will cause excessive wear and eventual
rupturing of the hose.)
3. Turn off the water supply to the heater module.
4. Trigger the gun momentarily to relieve trapped pressure.
IMPORTANT WHEN COLD WATER IS BEING PUMPED INTO THE
HEAT EXCHANGER AND THE BURNER IS ON, CONDENSATION
MAY FORM ON THE COIL AND DRIP.
APPEARANCE OF A LEAKING COIL PARTICULARLY IN COLD
HUMID WEATHER.
