and a remote control. The interior air distributor
is another component of the air conditioner, de-
pending on the installation.
4.1.1 External unit
The air conditioner’s external unit (Fig. 2-1) is in-
stalled on the vehicle’s roof (Fig. 2-2).

Fig. 3
4.2 Function
Compressor air conditioners function like a re-
frigerator: A refrigerant circulates in a closed
circulatory system. The gaseous refrigerant is
liquefied in a heat exchanger under the pressure
of a compressor. In the evaporator heat and
moisture are removed from the supplied room
air and then dissipated outside.
A fan distributes the cooled and dehumidified
air via the air distribution system into the vehi-
cle. The roof-mounted air conditioner ensures
cool air inside the vehicle.
4.3 Condensation
4.3.1 External condensation drain
Condensation is drained via the vehicle’s roof.
Holes are provided in the bottom of the external
unit for this, through which the condensation
drains.
With longer air conditioner operation, pools
of water can form under or beside the
vehicle.
Fig. 4
In most cases the condensation would run to
the front or rear of the vehicle.

4.3.2 Internal condensation drain*
The condensation is drained via an internal hose
system. The tube system is configured different-
ly depending on the vehicle manufacturer.
Fig. 5
4.4 Clearance
4.4.1 External unit clearance
The air conditioner draws in cooling air at both
sides and, after it passes the heat exchanger,
blows it out to the rear. For safe operation, the
air inlets and air outlets must not be obstructed
or misaligned.

4.6 Air distribution in the interior
4.6.1 Air distribution via the air distributor*
The warm room air is drawn in via the air dis-
tributor, through filters. The warm room air is
cooled by the air conditioner and flows directly
via the air distributor into the interior. The air
distributor is below the ceiling.
Fig. 11
The air distributor has four individually adjust-
able outlets. The air flow can therefore be dis-
pensed evenly and draft-free and distributed in
the vehicle.
(See: “6.13 Set air flow” on page23).
An integrated filter system in the air distributor
cleans the interior air. As the air distributor is
very flat, almost complete freedom of move-
ment is maintained.
The IR receiver for communication with the re-
mote control is on the air distributor (See: “4.8
IR receiver” on page13).

system in the ceiling. The cooled air flows from
the air conditioner via the ducted system into
the interior. The ducted system is between the
vehicle roof and the ceiling. It is installed by the
vehicle manufacturer and varies from model to
model.
See: Vehicle manufacturer’s operating
instructions.

6 Operation
6.1 Information on using air
conditioning systems
6.1.1 Check current consumption
The air conditioning system is configured for
current consumption up to 20 A.
Before switching on, check that the campsite
has adequate fuse protection (20 A).
6.1.2 Operation with generator or power
inverter
The air conditioner can be operated with a pow-
er inverter or generator. The following specifica-
tions are recommended:
• Power inverter type: Pure sine-wave voltage
• Nominal voltage: 110V - 130V AC
• Phase: 1
• Frequency: 60Hz. +/- 5%
• Inrush current capability: 250 ms with 115V /
60ARMS.
• Loads: ohmic and inductive
• Recommended power: min. 3000 W
Truma does not define the size of the gener-
ator in recreational vehicles. When sizing the
generator, the total power consumption of
your RV must be considered. Generators will

17EN
lose power at high altitudes and if they are
not maintained regularly.
NOTICE
The wrong power supply can cause
damage to and malfunctions in the
air conditioner.
With regard to the power supply, use
only sources with a pure sine wave
(e.g. voltage transformer, generator)
and without voltage spikes.
6.1.3 Incline
To prevent the compressor running dry, which
will result in premature wear and tear, the air
conditioner must not be operated at a side an-
gle of more than 8% (4.5°).
NOTICE
Damage caused by parking the vehi-
cle at an angle.
It cannot be ensured that the condensate
will drain. The service life and functions of
the compressor will be adversely aect-
ed.
Park the vehicle at a maximum lateral
and longitudinal angle of 8%.
6.1.4 Reduce heat radiation
To save power and cool the living area quicker:
Park the vehicle in the shade.
Close blinds or curtains.
Clean the vehicle roof regularly, as dirty roofs
heat up more.
6.1.5 Optimize interior climate
To ensure a healthy interior climate the differ-
ence between the inside temperature and the
outside temperature should not be set too high.
The circulated air is cleaned and dried during
operation. A pleasant interior climate is gener-
ated by drying the high-humidity air, even with
low differences in temperature.
Ventilate the vehicle thoroughly before oper-
ating the air conditioner, to remove accumu-
lated hot air from the vehicle.
Keep all doors and windows closed during
cooling mode, so condensation does not
form on the air distributor.
Direct the air flow in the room so it keeps the
air in the room moving.
6.1.6 Settings for fast cooling
• Set fan level to high
• Set front/rear air distribution to medium
• Set floor/ceiling air distribution to ceiling
(See: “6.13 Set air flow” on page23)
