OPERATING INSTRUCTIONS
HOT WATER OPERATION:
1. Follow the steps outlined for "COLD WATER OPERATION AND LIGHTING
PILOT VALVE." on page 21.
2. Move the control switch to the "BURNER" position. 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 ring when the trigger
is released.
At this point, the unit is operating as a hot water pressure washer. Be certain
to be extremely cautious when adjusting the pressure and controlling the
trigger gun and lance assembly to avoid the possibility of burns.
NOTE: While spraying, it is normal for the burner to re intermittently. The high
limit switch will cause combustion to cease when the temperature of
the discharged water exceeds the temperature setting of the switch.
Combustion will begin again when the water temperature drops
below the minimum setting.
