OPERATE VEHICLE COMPARTMENT AND CARGO HEATER Continued
Hold the RUN-OFF-START switch until the indicator light comes on. Then move the switch straight to RUN without
stopping in OFF position.
When using DF-2 fuel, set the HI-LO switch on HI only, and run for 1-3 minutes before
switching to LO.
Select the high or low heat with the HI-LO switch. The heater will always start on low heat no matter how the HI-LO
switch is set, and will go to high after it starts if the switch is at HI.
If the heater doesnt start, try again. If it doesnt start in three tries, troubleshoot heater (WP 0055 00).
Move the RUN-OFF-START switch to OFF to turn the heater OFF. The heater will stop burning right away, but the
blower will run until the heater cools off.
