Selecting A Location For The Roof Cowl; Electrical Connection; Warm Air Distribution; Miscellaneous - Truma S 3004 Instructions De Montage

Selecting a location for the roof cowl

The heater must always be operated with a roof cowl.
This must always be installed vertically or with a maxi-
mum incline of 15 degrees!
The location of the roof cowl must be chosen so that it is in
the air flow at all times during heater operation. Roof struc-
tures may interfere with the function of the heater.
If the heater goes out regularly while driving, the cowl
tops T-2 and T-3 are available in order to influence the
flow conditions. Test runs must be carried out if necessary.
The cowl top T-3 is essential for motor caravans.
If necessary, a cowl extension AKV must also be installed.
This must be secured with a screw.
An open roof window / lifting roof in the vicinity of the
roof cowl may allow exhaust gas to penetrate the interi-
or of the vehicle. The cowl must therefore never be positioned
near this opening. If this is not completely possible, the heater
must not be used when the roof window / lifting roof is open.
In order to make this clear, the installer must also affix a stick-
er (part no. 30090-37100) to the roof window / lifting roof in a
clearly visible location.

Electrical connection

12 V connection
If a Truma TEB-3 fan or lighting for the control panels is in-
stalled, a 12 V mains supply is required (alternating current
ripple is < 1.2 Vss). The heater must be connected to the
fuse-protected on-board power supply (5 A).
230 V connection ~, 50 Hz
When using a Truma TN-3 fan, a connection to the 230 V AC
supply and an external control panel are needed.
Safety instructions
The appliance must only be installed and repaired by an
expert.
Make sure that the power supply is disconnected! Pull out the
mains plug!
In-vehicle installations must comply with the technical and
administrative regulations of the respective country of use
(e.g. EN 1648, VDE 0100-721). National regulations and rules
must be followed.

Warm air distribution

Fire hazard or risk of malfunction if installed incorrectly
or if parts other than original Truma parts are used for
the warm air distribution.
– Use only original Truma parts for the warm air distribu-
tion. The heater is only tested and approved with these
components.
– Follow the installation instructions when installing the
warm air distribution.
The warm air system for the heater is designed individually for
each vehicle type using the modular design principle. A wide
range of accessories is available from Truma for this purpose.
In order to achieve even and quick warm air distribution
and to minimise the surface temperatures at the warm
air outlet grille, we recommend installing a Truma TEB-3 or
TN-3 fan. The heater S 5004 can be fitted with two fans. A
special installation box is available for this.

The fans are available as accessories for the heater –
operating and installation instructions are enclosed with
the fan.
If a water supply is being installed in the vehicle, it must
be ensured that sufficient room is left between the water
hoses and the heat source (e.g. heater, warm air duct).
A water hose may only be routed at a distance of 1.5 m from the
heater at the warm air duct. With lead-through, a spacer (e.g. in-
sulation) must be fitted in order to avoid contact. The Truma hose
clip SC can be used for distances greater than 1.5 m.

Miscellaneous

If a perforated drawer is installed over the heater that is used
for drying objects, for example, an intermediate shelf made
from non-coated wood must be installed (minimum depth
280 mm or 380 mm for S 5004). The covers of the installation
compartment must be made from temperature-resistant ma-
terial (not PVC or the like).

If the vehicle floor is being coated with underfloor protection,
all heater parts located beneath the vehicle must be covered
so that the resulting spray mist does not cause heater sys-
tem malfunctions. Remove covers again when the work is
complete.
