We recommend to independently conduct the following services:
For optimum performance, the heater should be taken to a specialized service center
for inspection and maintenance at least once a year.
If the heater is not in use, it is necessary to operate it once a month for 5-10 minutes,
including the warm season, to ensure reliable operation of the heater .
Regularly check the battery charge.
Before the start of the heating season, check the fuel tank. If the tank stored fuel for a
long time (for example from the past heating season), it is necessary to drain it! Rinse
the tank with gasoline or kerosene and fill it with fresh diesel fuel. This procedure is
designed to remove sediment formed in the fuel during prolonged storage. Failure to
follow this procedure can lead to clogging or failure of the fuel pump and increased
sooting in the combustion chamber.
In case of a long parking or storing the vehicle, disconnect the heater from the power
source (battery) to prevent it from discharging (current consumption of the heater out
of service is (30 ÷ 40) mA).
Reliable operation of the heater depends on the grade of fuel used. F uel grade is
selected depending on ambient temperature.
Malfunctions
.
Actions in the event of a malfunction.
check for the presence of fuel in the tank and the fuel line downstream of the fuel
pump;
check the 25A fuses;
check for loose connections in connectors and fuse holders (possible oxidation of
contacts);
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.
Check intake and output of the heating unit for free passage of heated air.
