Installation Instructions For Vehicles; Selecting A Location - Truma Combi Einbauanweisung

Installation instructions for vehicles

The installation of the device in vehicles must comply with
the technical and administrative regulations of the respective
country of use (e.g. EN 1949). The national legislation and
regulations (e.g. DVGW Work Sheet G 607 for vehicles in Ger-
many) must be observed.
The relevant employer's liability insurance association accident
prevention regulations must be observed in Germany for ve-
hicles used for commercial purposes (DGUV regulation 79 –
formerly BGV D 34).
In other countries, the relevant regulations must be observed.
More information about the regulations in the relevant des-
tination countries can be requested from our foreign rep-
resentatives (see www.truma.com).

Selecting a location

The unit and its exhaust duct must always be installed so that
they are easy to access at all times for service work (e.g. gas
and water connection via a service flap, furniture doors etc.)
and are easy to remove and install.
The distance between the unit and surrounding furniture items
or vehicle components must be at least 10 mm at all sides.
The scope of delivery includes a second type plate (duplicate)
with removable bar code.
If the type plate on the heater is not visible after the heater
has been installed, the second type plate (duplicate) must be
affixed to the unit in a clearly visible location.
The duplicate must only be used in conjunction with the
original.
Figure 1
In order to heat the vehicle evenly throughout, the heater
must be installed in a location in the vehicle that is as central
as possible in a wardrobe, stowage compartment or the like
with an adequate height, so that the air distribution ducts
can be routed with equal lengths. Appropriate openings must
be present in the installation compartment so that air can be
drawn in – see relevant sections concerning circulated air in-
take and warm air distribution.
In order to reduce the potential danger caused by a
heater becoming loose in the event of an accident, the
upper covering plate (17) of the installation cabinet can be
screwed to other pieces of furniture in a position that makes it
flush with the heater. Depending on the installation situation,
it may be necessary (especially with rear-mounted fixtures) to
install a stable furniture console (18) in front of (next to) the
heater, perpendicular to the direction of travel. For this pur-
pose, a solid spacer (minimum cross section 30 x 50 mm) can
be attached at a height of approx. 180 mm above the floor, or
a board (18a) for sliding in on a stable furniture console.
There must not be any heat-sensitive materials beneath the
unit (e.g. floor coverings such as PVC, cables etc.), since high
temperatures can occur at the base of the unit.
In order to prevent damage to components inside the equip-
ment, no cables or water lines of any kind may be attached to
the equipment's insulation.
The operation of important vehicle components must not be
adversely affected.

Cowls must be positioned such that exhaust cannot be drawn
into the interior.
The cowl must be in the form of a wall or roof cowl.

The wall or roof cowl must be attached such that there is
no fuel tank filler neck or fuel tank breather opening within
500 mm (R). There must also be no living area ventilation
openings or window openings within 300 mm.

If the cowl is being installed directly underneath a win-
dow that will be opened, an electric window switch
(part no. 34000-85800) must be installed.
