ACTIONS
E-2
Over-voltage
or
Under-voltage
Supply voltage is detected outside range (9-16V).
• Check battery charge level and condition
• Check fuse condition and connection
• Check cable condition and for excessive voltage drop.
E-3
Glow plug failure
• Contact service support to arrange inspection or replacement
of the glow plug.
E-4
Fuel pump failure
• Contact service support to arrange inspection or replacement
of the fuel pump.
E-5
Overheating
Inlet air above 50°C or Internal heat exchanger above 230°C.
• Allow heater to cool down, then check intake and hot air ducts
for any blockage, crushing or restriction and clear and retry operation.
• Contact service support to arrange inspection or replacement
of the fan or temperature sensor.
E-6
Fan failure
• With the heater off and power disconnected, check if the impellor
can rotate freely.
- Remove anything blocking or interfering with the rotation
of the fan impellor and retry operation.
• Contact service support to arrange inspection or replacement of fan
E-8
Fail to start
• Check the current capacity of the power source is at least 15A (for
example the heater will not start when powered off a regular car cigarette
socket or an outlet rated under 15A)
• Check the fuel level in the tank and refill if needed
• Check the fuel condition, if it is old or degraded then drain the tank
and replace the fuel with fresh diesel
• If at low temperatures, check that correct winter or alpine diesel is used
otherwise the fuel may wax up and block the pump
• Check the combustion intake and exhaust openings are not blocked
or damaged
• Contact service support to arrange inspection or replacement of fuel
system, combustion ducting and temperature sensors
Flameout
• If the heater had been recently used, the temperature of the heat
exchanger can be too high. Allow the heater to fully cool then retry
starting the heater
• If during attempted start, there is allot of white smoke:
- Contact service support to arrange inspection or replacement
of the glow plug and screen and operation or the fuel pump
• If during attempted start, there is little or no white smoke:
- Check the combustion intake and exhaust openings
are not blocked or damaged
- Check the fuel level in the tank and refill if needed
- Check the fuel condition, if it is old or degraded then drain
the tank and replace the fuel with fresh diesel
- If at low temperatures, check that correct winter or alpine diesel
is used otherwise the fuel may wax up and block the pump
- Contact service support to arrange inspection or replacement
of the glow plug and screen and operation or the fuel pump
• Contact service support to arrange inspection or replacement
of temperature sensor
E-9
Temperature
sensor failure
• Contact service support to arrange inspection or replacement
of temperature sensor
