CHECK-LIST AT SERVICE FAILURES
The fuel is not moving:
The movement can
be checked by lifting the suction hose out of
the tank for a few seconds; there will be an air
bubble moving with the fuel.
- Check the tightness of the joint: if necessary,
make the joint tighter.
- Check the hose: replace a leaking hose with
a new one.
- Make sure that the pump receives voltage;
the pumping sound or voltage variation when
measuring the voltage.
No voltage is received:
the yellow light is not
on.
- Check the charging of the battery.
- Check the connections of the battery or po-
wer-supply unit.
- Check if the automatic fuse has tripped and
come up, press it down if necessary. Check
the main fuse connected to the electric con-
ductor and replace it if necessary.
Under-voltage:
the yellow light is blinking.
- Charge the battery or replace it with a more
powerful one.
- Replace the electric conductors with thicker
ones; see installation instructions.
Too much fuel is received:
the heater is over-
heated and cuts off its function by itself.
- Check that the fuel surface of the tank is be-
low the lower surface of the heater
- The exhaust gas or fire ventilation hose is
blocked.
- Remove obstacles and blockages
Fuel and voltage is received normally, but
the device will not start:
- Check through the inspection port whether
the glow plug is glowing at start-up, change
it if necessary.
- Check the fuel composition and if there is any
suspicion that water may have condensed
into the tank, remove the water; see mainte-
nance instructions.

red and yellow signal lights have gone out.
If necessary, contact the nearest Wallas servi-
