facturer) is responsible for
providing instructions for use
for the user as well as for
identification printing on the
control panels!
Provide space for the control
panel at an easily visible lo-
cation. Length of the connec-
tion cable 3 m. If required, a
5 m extension cable is avail-
able (8 m in combination;
Part no. 34300-01).
If it is not possible to install
the control panels flush
with the surface, Truma can
provide a surface-mounting
frame (45) on request, as a
special accessory (Part no.
40000-52600).
1. Fig. L:
The control panel
for gas operation (46) and
(if provided) the control panel
for electrical operation (47)
should be fitted next to one
another if at all possible
(distance between centres
of holes 66 mm).
2. In each case, drill a hole
with diameter 55 mm
(distance between centres
of holes 66 mm).
3. Plug the control panel ca-
ble (48) to the control panel
for gas operation (46) and
then fit on the rear cover cap
(49) as a stress-relieving
device.
4. Push the cables through
to the rear and lay the con-
nection cable (48 + 50) to the
heating unit.
5. Secure both control panels
with 4 screws (51) each and
fit the cover frame (52) on
them.
To round off the appear-
ance of the cover frame,
Truma can provide side piec-
es (53) as special accessories
in 8 different colours (please
ask your dealer).
Connecting the
room temperature
sensor and control
panel to the system
Fig. N:
Take off the top cover
of the electronic control unit
(54) and plug in the connec-
tion cable from the room
temperature sensor (55 – no
need to be concerned about
polarity), the control panel
(48), and, if appropriate, the
timer switch (56). Slide the
cover back on.
Electrical
connection 12 V
Electric cables, switching
units and control units for
heaters must be arranged in
the vehicle in such a way that
their satisfactory operation
cannot be adversely affected
under normal operating con-
ditions. 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. Swit ching
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.
Fig. N:
To guarantee op-
timum power supply, the
heating system
must
be
connected to the fused on-
board network (central elec-
tronics unit 10 A)
with a 2 x
2.5 mm² cable
(for lengths
over 6 m with 2 x 4 mm² ca-
ble). If relevant, voltage drops
in the supply cable must be
taken into account. Connect
the negative lead to the cen-
tral earth. If connected di-
rectly to the battery, the posi-
tive and negative leads must
be fused. Use fully-insulated
6.3 mm push-on receptacles
(57) for the connection.
Do not connect any other
consumers to the supply line!
When power supplies
are being used, it must
be noted that the output volt-
age is between 11 V and 15 V
and the alternating current
ripple is < 1.2 Vpp.
The Truma battery
charger NT 12/ 3-18
(Part no. 39901-01) is rec-
ommended for connecting
multiple 12 V devices. This
charger (with a charging cur-
rent of 18 A) is suitable for
charging lead-acid or lead-
gel batteries. Other charg-
ers must only be used with
a 12 V battery as a buffer.
Mains power supplies and
other power supply equip-
ment must have a controlled
12 V output (AC component
less than 1 Vpp).
For saving the battery
we recommend using
solar collectors. Please ask
for information from your
dealer.
Electrical connection
of the safety/drain
valve
Fig. G:
Connect the valve
with the red continuous cur-
rent cable (+) to the fused
vehicle power supply (1 A).
Connect the 2-pin cable with
double connector (58) to the
control panel. Truma supplies
a 50 cm long extension cable
(Part no. 70070-08500) as a
special accessory.
It must be ensured that the
cable is not routed over the
air distribution pipes and/or
any hot parts of the equip-
ment such as the base!
The brown cable (59) is pro-
vided for the remote control
of the safety/drain valve (refer
to operating instructions –
accessories).
Electrical
connection 230 V
(special version)
The electrical con-
nection is only to be
carried out by an expert (in
Germany, acc. to VDE 0100,
Section 721). The information
given here is not intended as
instructions for you to carry
out. It is for assisting the
expert assigned to carry out
the job, acting as auxiliary
information when connecting
the appliance!
Connection to the mains sup-
ply is effected by means of
cables 3 x 1.5 mm² (e.g. hose
line H05VV-F) to a distribu-
tor box (not included in the
scope of supply).
Always make sure to con nect
carefully, observing the cor-
rect colours!
For maintenance and repair
work a disconnecting device
must be provided on the ve-
hicle for all- pole disconnec-
tion from the power supply,
with at least 3.5 mm contact
clearance.
Mount splitting box near
to the appliance – on the
vehicle floor or on the wall
(length of cable: 90 cm).
Connect operating unit cable,
feed lead 230 V, and heat
sleeve cable as shown in the
illustration.
1 = control panel cable
2 = supply 3 x 1.5 mm²
3 = heating collar cable
4 = brown
5 = green
6 = blue
7 = yellow
8 = white
9 = yellow/green
All cables must be secured
with cable clips.
Function check
After installation, the gas
feed line must be tested
for tightness by the pres-
sure-drop method. A test
certificate (in Germany, for
example, in accordance with
DVGW Worksheet G 607 for
motor vehicles or G 608 for
boats) is to be issued.
Then check all functions of
the appliance, as specified in
the operating instructions, in
particular the water content
draining function.
There
shall be no guarantee
claims for damage caused
by frost!
The operating instructions
and completed guarantee
card are to be given to the
owner of the vehicle.
Warning
information
The installer or vehicle owner
must apply the yel low sticker
with the war ning informa-
tion, which is enclosed with
the applian ce, to a place in
the vehicle where it is clearly
visible to all users (e.g. on
the wardrobe door)! Ask
Truma to send you stickers,
if neces sary.
