Circulating air return
Fig. F: The circulating air (U)
is sucked directly back into
the appliance.
If the heating appliance is
installed in a stowage com-
partment or similar, make an
appropriately sized opening
2
(approx, 200 cm ) for circu-
lating air feedback.
Do not block air ducts
to heating appliance!
Warm air supply
and circulating air
return with outside
assembly
Refer to installation variants
Fig. 4 + 5 (Page B).
The warm air duct and re-
circulating air duct between
the heater and the vehicle
– especially in the area prone
to stone demage – must be
made from flexible LF air
ducting or, in the protection
zone, from LI air ducting
(106 mm in diameter)
A protective casing over the
entire heater system protects
it against damage and wea-
ther conditions and simulta-
neously serves as insulation.
Fig. G1: Drill two openings
with a diameter of 100 mm.
Apply sealing agent to flange
of both connector fittings
(41) and bolt to the openings
on the outside. Place the
grid (47) in the recirculating
air duct between the suc-
tion connection fitting and
the vehicle wall. Thread LFS
wire clamps (42) onto the air
ducts (43). Slide the air ducts
over the heater connection
fittings (44) and the connec-
tor fittings (41) and fasten
them with the LFS wire
clamps (42). Seal the joints
with silicon paste.
Fig. G2: Seal hollow double
walls around the air duct
by putting two rolled sheet
metal strips (45) or lengths
of pipe between 97 an
100 mm in diameter into
the openings.
Fig. G3: The warm air can be
extended inside the vehicle
using LI air duct (diameter
106 mm). To connect the air
duct, fasten another conec-
tion fitting (41) into the open-
ing. The two connector fit-
tings can be bolted together
through the wall.
Fig. G1: If you wish the
warm air to be diffused
inside the vehicle, an air dif-
fuser (46) can be fitted over
the warm air duct (W) with
4 bolts.
Do not close off or re-
strict the opening for
the recirculating air duct!
The air diffuser (46) has
2 connections for VR duct
(72 mm diameter), neither
of which must be closed off.
The protective metal sheet
supplied (48) acts as a heat
shield and must be securely
fastened over the air diffuser
(46). Stowage protection
can be provided in the form
of another protective metal
sheet (49) fastened over the
opening for the recirculating
air duct (special accessory
Part no. 39010-11500).
The warm air system is de-
signed for each type of vehi-
cle individually, on a modular
basis. There is an extensive
accessories program avail-
able (refer to brochure). You
can obtain sketch diagrams
free of charge from the
Truma Service Centre,
showing optimal installation
suggestions for warm air
systems in all current-type
caravans and mobile homes.
Fitting the
control panel
When using control
panels which are
specific to the vehicle or
manufacturer, the electrical
connection must be effected
in accordance with Truma
interface specifications. Any
modification made to the
Truma components pertain-
ing to this will lead to the
cancellation of the guarantee
and to the exclusion of any
claims for liability. The install-
er (manufacturer) is respon-
sible for providing operating
instructions for the user as
well as for the labelling of the
control panels!
When selecting the location,
take note that the control
panels must not be subjected
to any direct radiant heat.
Length of the connection
cable 4 m or 10 m.
If installation is only possible
behind curtains or in similar
locations with temperature
fluctuations, a remote sensor
for the ambient temperature
must be used (special
accessory).
Installing the flush-
fitted control panel
If it is not possible to
instal the control panel
in a location flush with the
surface, Truma can provide,
on request, a surface-mount-
ing frame (1 – Part no.
40000-52600) as a special
accessory.
1. Fig. H1: Drill a hole
55 mm in diameter.
2. Plug the control panel ca-
ble (2) into the control panel
(3) and then fit the rear cover
cap (4) as a stress-relieving
device.
3. Push the cable through to
the rear and lay it to the elec-
tronic control unit.
4. Secure the control panel
with four screws (5) and fit
the cover frame (6) in place.
For the connection to
the cover frame, Truma
can provide a set of side ele-
ments (7) as a special acces-
sory, Part no. 34000-61200.
Installing the special
control panel
Fig. H2: For existing installa-
tion sections.
1. Remove the cover screen
from the installation section.
2. Plug the control panel ca-
ble (10) into the control panel
(8), feed it to the rear through
the installation section, and
lay it to the electronic control
unit.
3. Push the control panel (8)
in until the front face is flush
with the surface.
If there is no installation
section present, the
control panel can be fitted
with the flush-fitting installa-
tion frame provided.
If installation flush with
the surface is not possible,
Truma can provide a surface
mounting frame (Part no.
39050-11600) as a special
accessory.
Fitting the
electronic
control unit
1. Fig. H3: Unscrew the
cover of the control unit.
The plug on the elec-
tronic control unit
should only be withdrawn or
plugged in if the supply volt-
age had been disconnected
beforehand. Pull the plug out
straight!
2. Insert the plug on the con-
trol panel cable (1) as shown
in the diagram onto the red
terminal strip of the control
unit.
If a timer switch or a
fine sensor is fitted, its
plug is to be inserted on the
red terminal strip. If several
accessory components are
being used at the same time,
connection is effected via the
multiple socket (Fig. H5: 6).
3. Secure the lower part with
two screws at an easily ac-
cessible location, protected
against moisture (must not
be heated to above 65°C).
4. Screw the cover of the
control unit into place.
If the appliance is assembled
on the outside of the vehicle,
the electronic control unit
must be installed inside the
vehicle, where it is protected
against moisture and dam-
age. Drill an opening of
25 mm diameter in the floor
or wall, disconnect connec-
tor (Fig. H3: 2) of 20-pin ca-
ble form the control unit and
pass through the opening.
Seal with cable grommet.
Re-insert connector.
In special cases, the elec-
tronic control unit can be
assembled on the outside
of the vehicle, in a protective
box, for the electronics on
the outside (special acces-
sory Part no. 39950-00).
