Installing the air conditioning system
when space is restricted
Preparation
Fig. B
Remove installation materials and remote control from stow-
age compartments (a and b) of the unit.
Fig. C
Open clamping straps and remove the 4 fastening brackets.
1. Fig. C
Place installation template in stowage compartment and fix
in position. Mark the mounting holes for the 4 side fastening
brackets (3) and the 2 front and rear brackets (2) (leg must be
pointing towards the outside!).
2. Mark floor opening "LE" for the supply air intake, "LA" for
the supply air outlet and "KO" for the condensation drain.
3. Remove installation template and drill or cut out the "LE",
"LA" and "KO" openings. Then seal the edges of the openings
in the floor of the vehicle with underbody protection.
Before drilling, always check for underlying / concealed
cables, gas lines, frame sections and the like!
4. Screw on the 4 side fastening brackets (3) with 2 screws
per bracket and the 2 brackets (2 – leg must be pointing to-
wards the outside!) with 3 screws per bracket.
The air conditioning system must be attached at all
sides using the brackets provided in order to prevent
unintentional movement if vigorous movements occur (e.g.
hard braking).
5. Insert connection (11) for condensation drain (KO) from
above.
6. Lead the two clamping straps (4) through the 4 fastening
brackets (3), as shown in the illustration (lettering on clamping
strap should be facing the floor). Insert air conditioning sys-
tem into the stowage compartment and secure with the two
clamping straps (4). Ensure that the clamping straps are in the
provided recesses on the device. Guide clamping straps (4)
through buckle (6) as shown in illustration and tighten.
When installing the unit, please ensure that the
connection (11) of the condensation drain is lo-
cated in the recess in the floor of the vehicle. Otherwise
there is a risk of water penetrating the interior! In order
to provide perfect air circulation the apertures in the
base of the equipment and the floor must be exactly
aligned. If this is not the case the equipment is not
guaranteed to operate correctly!
7. Seal connection (11) for condensation drain all round from
below using body sealant.
8. Attach the two floor grilles (5) for LE and LA to the floor
of the vehicle from below with suitable screws or clips (not
provided).
Cold air distribution and circulated air
return

Cold air distribution

A KR 65 Ø 65 mm cold air duct (10) with at least one outlet
must be connected to each of the three cold air outlets of the
device (7, 8 + 9).
Slide the cold air ducts (10) into the cold air outlets of the
device and route to the air outlet nozzles. For noise reduction
purposes, Truma can supply a sound muffler for installing in
the cold air system (part no. 40040-60100).
The swivel air outlet SCW 2 (black – part no. 39971-01 or beige
– part no. 39971-02), the end outlet EN-O (part no. 40171-07)
with lamella inset LA (part no. 40721-01/02/03/04/05) or the
rectangular air outlet RL (part no. 40280-01) with connector
piece ANH (part no. 40290-02) would be suitable as an outlet
for the cooled air into the vehicle interior.
Important notes
The cold air distribution is designed individually using the
modular principle for each vehicle model. A wide range of
accessories is available for this purpose.
In order achieve the maximum cooling power we recommend:
– Route cold air ducts to air outlet nozzles as short and
straight as possible.
– The total accumulated length of cold air duct that may be
used is 15 m.
– Connect the longest cold air duct (max. 8m) to the right-
hand cold air outlet (9), since this has the highest air
throughput.
– In order to avoid condensation, do not route the cold air
ducts in the vicinity of heat sources (e.g. power supplies or
behind the refrigerator).

Circulated air return

The circulated air is drawn in again by the device, either via
an additional air grille (1 – accessories, part no. 40040-29200),
e. g. in the stowage box wall, or via several small openings
with a total area of at least 300 cm
Important note
The ventilation from the vehicle interior to the installation
area must be in the immediate vicinity of the equipment to
provide perfect air exchange. Covers must be fitted if neces-
sary to prevent the circulated air return from being affected by
stowed objects.
If installation in close proximity is not possible, Truma
can provide a flexible air conditioning intake as an acces-
sory (part no. 40090-59100).
