The fan runs on for approx.3 minutes to cool down then restart again.
Switching off
Press the button which the corresponding indicator light is on.
Indicator light extinguished and fuel pump stop working after switching off the heater. The
fan running and cooling down continuously about 3 minutes in the switch off process.
Control and safety devices
If the heater does not ignite within 90 seconds after starting the fuel pump, the start is
repeated. If the heater still does not ignite after another 90 seconds of pumping fuel, the
heater is switched off, i.e. the fuel supply is off an the fan runs on for approx.3 minutes.
If the flame goes off by itself during operation, the heater is restarted. If the heater does not
ignite within 90 seconds after the fuel pump has started or ignites and goes off again
within 15 minutes, the heater is switched off, i.e. .the fuel supply is off and the fan runs on
for approx.3 minutes. This status can be remedied by briefly switching off and on again.
Do not repeat the switching off/on routine more than twice.
In the case of overheating, the combined sensor (flame sensor/overheating sensor) triggers,
the fuel supply is interrupted and the heater switched off. Once the cause of the
overheating has been switching off and on again.
If the lower or upper voltage limit is reached, the heater is switched off after 20 seconds.
The heater does not start up when the glow plug is defect of when the electric lead to the
dosing pump is interrupted.
If the combined sensor (flame sensor/overheating sensor) is defect or the electric lead
interrupted, the heater starts up and is then switched off again during the start phase.
The speed of the fan motor is monitored continuously. If the fan motor dose not start up or
if the speed deviates by more than 10%, the heater is switched off after 30 seconds.
When the heater is switched off, the glow plug is switched on for 40 seconds
(after-glowing)while the fan runs on to clean off any combustion residues.
Emergency shutdown
If an emergency shutdown is necessary during operation, proceed as follows:
Switch the heater off with the control or
Pull the fuse out of
Disconnect the heater from the battery
Note
Do not switch the heater off and on again more than twice.
6. Troubleshooting
Circuit troubles may be caused by different reasons, such as corrosion of connectors, poor
contact of connectors, wrong connection of wires, corrosion of wires or fuse, corrosion
and looseness of battery poles, etc. Users need to check and prevent such troubles and
offer good maintenance.
The reasons for the troubles to the heater can be indicated by the green LED on the control
switch. In trouble status, indicator light will flash circularly, each circulation include 2
seconds extinguishing and a few 0.5 seconds times of slow flashes appear alternately.
During the period between two long extinguishing, the times of slow flashes represent the
types of troubles.
During use, the heater may become unable to start normally or die out after start. Such
