Do not obstruct air passages to the appliance!
If the storage compartment is to remain in full use, the return
air can be drawn in through a swivel nozzle SCW 2 and a duct
piece VR 80. For this purpose screw a connection fitting over
the opening (U). Overall length up to the appliance max. 2 m!
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 pertaining
to this will lead to the cancellation of the guarantee and to the
exclusion of any claims for liability. The installer (manufacturer)
is responsible 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 (Accessories).

If there is no installation section present, the control
panel can be fitted with the flush-fitting installation frame
provided.
If flush mounting is not possible, Truma will supply an on-
surface frame (part no. 39050-11600) as an accessory on
request.
Fitting the electronic control unit
Unscrew the cover of the control unit.
The plug on the electronic control unit should only be
withdrawn or plugged in if the supply voltage had been
disconnected beforehand. Pull the plug out straight!
Insert the plug on the control 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 (Accessories).
Secure the lower part with two screws at an easily accessible
location, protected against moisture (must not be heated to
above 65° C).
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 damage.
Drill an opening of 25 mm diameter in the floor or wall, dis-
connect connector (2) of 20-pin cable form the control unit
and pass through the opening. Seal with cable grommet. Re-
insert connector.
In special cases, the electronic control unit can be assembled
on the outside of the vehicle, in a protective box, for the elec-
tronics on the outside (Accessories, part no. 39950-00).
Electrical connection 12 V / 24 V
Electric cables, switching units and control units for heaters
must be arranged in the vehicle in such a way that their satis-
factory operation cannot be adversely affected under normal
operating conditions. All cables leading to the outside must be
splash proof at the leadthrough opening.
Prior to working on electric components the appliance
must be disconnected from the power supply. Switch-
ing off at the control panel is not sufficient!
When carrying out electric welding work on the body the
appliance connection must be disconnected from the vehicle
electrical system.
If the connections are transposed there is a risk of cable
burning. This also rules out any guarantee or liability
claims!
The red cable is positive, the blue cable is negative!
Connect the appliance to the fused vehicle electrical system
(central electrical system 5 – 10 A) using the 2 x 1.5 mm
cable, for lengths over 6 m use 2 x 2.5 mm
cable to central ground. For direct connection to the battery
the positive and negative cable must be fused. Connections in
Faston terminals, fully insulated (motor vehicle flat connector
system, 6.3 mm).
