Connection 12 V; Connecting Room Temperature Sensor To The Unit; Connecting Control Panel To The Unit; Connecting Metering Pump - Truma Combi D 6 Einbauanweisung

All cables must be securely attached and must not become
loose or disconnected due to vibration - risk of fire!

Connection 12 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. 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.
The unit is equipped with reverse polarity protection. If
the unit is connected with incorrect polarity, there will be
no display on the LED. The unit can be used after establishing
proper polarity and replacing the fuse (64).
In order to guarantee an optimum electricity supply, the heat-
ing must be connected to a fused onboard network (20 A
fuse in the main electrics). If relevant, voltage drops in the
supply cable must be taken into account.
Cable length
– 5.0 m
5.0 m – 7.5 m
Connect the negative lead to the central earth. If connected
directly to the battery, the positive and negative leads must be
fused. For the connections (61, 62), we recommend 6.3 mm
fully insulated flat connectors.
Do not connect any other consumers to the supply line!
When power packs or power supply units are being used,
note that the output voltage is between 11 V and 15 V
and the alternating current ripple is < 1.2 Vpp. We recom-
mend the automatic chargers from Truma for the different
applications. Please ask your dealer. All chargers may be used
only with a 12 V battery as a buffer.

Connecting room temperature sensor to the unit

Plug the connection cable's plug onto connection (67)
(no need to observe polarity).

Connecting control panel to the unit

Insert the plug (52) of the connection cable (51) into one of
the connections (68 or 69). Make sure that the plug engages.

Connecting metering pump

If an automatic filling unit is used to fill the fuel lines,
make electrical connection to metering pump after filling.
Diameter
2 x 4.0 mm²
2 x 6.0 mm²
Attach connector (74) of connecting cable to metering pump
and connector (75) to connection (70) of unit. Please ensure
that connectors engage properly.
Wind up excess cable and secure in a suitable location using
cable binders.

Extraction fan connection

Attach connector (11) of extraction fan cable to unit connec-
tion (72). Ensure that the plug engages. Roll up excess cable
(9) and fix with cable binders at a suitable point.

Initial start-up

During the initial operation of a brand new appliance a slight
amount of fumes and smell may be noticed for a short while.

Filling the fuel lines

The heater normally has to be started up several times to fill
the fuel lines if an automatic filling unit is not being used (part
no. 34020-44700).
Connect unit to control panel to do this. The unit automatically
performs 2 start attempts (initial start and repeat) per switch-
on procedure with a run time of 2 minutes in each case. If no
flame is detected after the repeat start, the unit switches to
fault and has to be switched off and on again at the control
panel.
After a total of 15 unsuccessful starting attempts (initial
and repeat start) without forming a flame, the equipment
is blocked. To remove the block, please contact the Truma
Service Centre (see Service Booklet or www.truma.com).
Check fuel lines and connections for leaks after filling the fuel
lines.

Function check

Check all of the device functions according to the instructions
of use; particularly emptying the water contents. There shall
be no guarantee claims for damage caused by frost!
The operating instructions must be handed to the owner of
the vehicle.

Warning information

The installer or vehicle owner must apply the yel low sticker
with the war ning information, 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.
