5 Recommendations
If the heater does not start after switching on, make sure there is fuel in the tank, check
the charge of the battery, check if all connectors are properly connected and if the 25A fuses
are viable.
If you are unable to find the primary cause of a fault, contact your nearest dealer or
service centre, or check the website www.autoterm.com.
WARNING!
When starting the heater for the first time after installation, it is preferable
to fill the main fuel line up to the input nozzle of the heater using a priming
device. If there is no priming device, start the heater several times until the
main fuel line is filled.
It is important to remember that if the heater has not started after activation,
the control unit will restart the heater in automatic mode. If the heater does
not start after two attempts, a fault code will be displayed on the control
panel. (Look for fault codes table in “Section 6 – Malfunctions” in this
manual)
For correct operation, the heater needs regular (annual) maintenance. Stop the heater
and let all system parts cool down before any maintenance or repair work:
- check for corrosion on electrical plugs and contacts (with the battery disconnected);
- check the fuel and coolant hose seals;
- check the exhaust gas system for corrosion and sealing;
- check if the air intake pipes and air ducts are clean;
- check all air ducts for damage;
- run a computer diagnostic of the heater.
Periodic, preventative maintenance is important and must be carried out to
ensure reliable operation of the heater. See the table of periodic maintenance
in “Annex 5”.
To ensure the reliable operation of the heater, switch it on at least once a month
for 20 minutes, including during the warm seasons of the year when the heater is out
of operation. This action is necessary to remove any viscous film sediments on the
moving parts of the fuel pump. Failure to do so may lead to premature failure of the
heater.
For diesel heaters. If separate a fuel tank is used, fuel in the system has to be
changed at least once a season. 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 extended parking or vessel/vehicle storage, disconnect the heater from the
power source (battery) to prevent it from discharging (current out of season heater
consumption is (30 ÷ 40) mA).
