Fig. 5-19: Control Element Knob Range
Once the installation has been inspected, insert the main power fuse and
set the control element knob to the full heat position (see figure 5-19).
Allow the heater to run through 2 start-up attempts. Watch the clear fuel
line for indications of air bubbles and fuel. Depending on length of fuel
line, it may take a few start attempts before the fuel reaches the heater. If
the fuel line does not prime right away, switch heater off and back on to
reinitiate the start-up cycle.
Once the heater starts, allow it to run until all trapped air bubbles have
escaped and heater operation sounds smooth and consistent.
After the heater is in operation, all fuel connections must be checked for
leakage and all lines/wiring for secure fastening.
Using the information from the heater identification plate, complete the warranty card and send to Webasto
Thermosystems for warranty registration.
