Truma Combi D 4 Operating Instructions Manual page 12

Safe operation
– During heater operation, do not allow the
fuel display in the fuel tank to drop to the
"low fuel" mark.
If the vehicle fuel tank runs empty, the open-
ing of the fuel removal duct is roughly at the
same height as the surface of the fuel. In
this state, particularly when the fuel in the
vehicle fuel tank is slopping around due to
vehicle movement, a large amount of air is
sucked in. This leads to an irregular supply
of fuel to the heater. The heater burner is
unable to maintain clean combustion in this
condition, leading to the formation of smoke
and odours.
– Ensure that the inside of the vehicle is suf-
ficiently ventilated. When the unit is started
up, there may be some smoke and/or smell
due to dust or dirt. Especially if it has not
been used for a long time.
– The appliance can be used by children aged
8 and over, as well as by persons with re-
duced physical, sensory or mental capabili-
ties or with a lack of experience and knowl-
edge, provided that they are supervised or
have been instructed on how to use the ap-
pliance safely and that they understand the
resulting risks. Children must not be allowed
to play with the appliance.
– The exhaust double duct (exhaust gas sound
muffler and extraction duct) must be in-
spected regularly, particularly following long
journeys, to check for any damage and to
ensure that the connection is sound. The
same applies to the mounting of the heater
and the cowl.
Operation while driving
– The heater must not be used during refuelling
or in enclosed car parks, in garages, or on
ferries.
– To prevent damage to the appliance from
spray water, such as when cleaning the ve-
hicle, do not spray water directly into the
wall cowl.
