Working on the appliance, in the
installation compartment
Possible danger from electric shock or
explosion as a result of escaping gas!
– Before starting any work:
1. Switch off the appliance
2. Close off the gas supply
3. Disconnect the appliance from the power
supply and mains (230 V ) at all poles
Possible risk of cut injuries from sharp
edges!
– Wear suitable protective gloves and goggles
when carrying out all work.
A safe operating environment
– The appliance may be operated only with
appropriate Truma control panels and
accessories.
– It is not permissible to operate the appliance
without a warm air duct.
– Danger of toxic exhaust fumes. The heater’s
exhaust can be toxic in enclosed spaces (e.g.
garages, workshops, awnings). If the vehicle
is parked in closed rooms:
– Shut off the fuel supply to the heater
– Deactivate the time switch
– Switch off the heater at the control panel.
– Switch off the heater via the Truma App if a
Truma iNet Box is installed.
– If the cowl has been placed near or directly
beneath a window that can be opened, the
appliance must be equipped with an auto-
matic shut-off device in order to prevent op-
eration with the window open.
– Possible fire hazard from higher temperatures!
• Never use heat-sensitive items (e.g. spray
cans, candles) or flammable materials,
liquids gaseous substances or vapours
near to the appliance, in the installation
compartment or in the appliance itself
• Never block the warm air vents of the
warm air distributor or bring heat-sensitive
objects or flammable materials, liquids,
gaseous substances or vapours into or into
the vicinity of the warm air distributor
• The openings for the circulated air intake,
the installation compartment and the in-
stallation compartment itself must be kept
free of obstacles so that the appliance does
not overheat
– It is prohibited to use products containing
chlorine on and in the appliance.
– The cowl for the exhaust gas system and the
combustion air infeed must be kept free of
contamination (slush, ice, leaves etc.) at all
times.
– Danger from hot surfaces and exhaust gas.
Do not touch the area around the wall cowl
and do not lean any objects against the
wall cowl or the vehicle.
Obligations of the operator / vehicle owner
– The operator is responsible for the water
with which the Combi boiler is filled, and for
its quality.
– Maximum feed water pressure, see “Safety
instructions” on page 3.
– The vehicle owner is responsible for correct
operation of the appliance.
– The Combi has no built-in frost protection func-
tion. Freezing water can cause serious damage
to the appliance. The operator is responsible
for protecting the Combi against frost damage,
e.g. by using the Truma FrostControl. In
appliances without FrostControl (e.g. the
UKversion) or when the appliance is not in op-
eration, it is essential to drain off the water
content if there is a risk of frost. No claims may
be made under the warranty for damage
caused by frost.
– The installer or vehicle owner must affix the
supplied yellow sticker with the warning
information in a location in the vehicle
where it is clearly visible to all users (e.g.
the wardrobe door). Missing stickers can be
requested from Truma.
– Liquid gas systems must comply with the
technical and administrative regulations of the
respective country of use (e.g. EN 1949 for ve-
hicles in Europe). The national legislation and
regulations (e.g. DVGW Work Sheet G 607 for
vehicles in Germany) must be observed.
– The vehicle owner must arrange for the gas
system to be tested in accordance with the
relevant national regulations (in Germany
every 2 years) by a liquid gas expert (DVFG,
TÜV, DEKRA). The test must be confirmed
on the respective test certificate (G 607).
