Malfunctions .
Actions in the event of a malfunction.
x check for the presence of fuel in the tank and the fuel line downstream of the fuel
pump;
x check the 25A fuses;
x check for loose connections in connectors and fuse holders (possible oxidation of
contacts);
x disconnect the power connector for 1-2 minutes and re-connect it again.
All other problems can be identified by the fault code, which is displayed on the
Controller.
*Attention! If, during start-up and operation of the heater the error message
"Overheating" is repeated 3 times in a row, the heater will be locked. Locking is made
upon actual overheating, regardless of input from the sensors that produced errors. In case
of locking, the controller display will show code 33. To unlock the heater you need to
contact a service center.
We recommend not to wait for the lock of the heater, and immediately after the first
overheating start troubleshooting causes of failure.
x Check intake and output of the heating unit for free passage of heated air.
x Check the Overheating Sensor on the heat exchanger and replace if necessary.
* - only for the heaters of the PLANAR-8D type.
