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 tension straps and remove the 4 fastening brackets.
1. Fig. C
Place installation template in stowage compartment and fix in
position. Mark mounting holes for the 4 side fastening brack-
ets (3) and the 2 front and rear retaining brackets (2 – leg must
be on the outside!).
2. Mark floor opening „LE" for the air supply, „LA" for the out-
going air 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 underfloor protection.
Before drilling, always check for underlying / concealed
cables, gas lines, frame sections and the like!
4. Screw down each of the 4 side fastening brackets (3) with
2 screws and each of the 2 retaining brackets (2 – leg must be
on the outside) with 3 screws.
The air conditioning unit must be attached at all sides
using the brackets provided in order to prevent unin-
tentional movement if vigorous movements occur (e.g. hard
braking).
5. Insert muff (11) for condensation drain (KO) from above.
6. Guide the two tension straps (4) through the 4 fastening
brackets (3) as shown in the illustration (lettering on tension
strap should be facing the floor). Insert air conditioning unit
in stowage compartment and secure with the two tension
straps (4). Ensure that the tension straps are positioned in
the recesses provided on the unit. Guide tension straps (4)
through the clasp (6) as shown in the illustration and tighten.
When installing the unit, please ensure that the
muff (11) of the condensation drain is located in
the recess in the floor of the vehicle. Otherwise there is
a risk of water penetrating the interior! In order to pro-
vide good air circulation, the openings in the bottom of
the unit and the floor must align exactly. Correct opera-
tion of the unit cannot be guaranteed unless this is the
case!
7. Seal muff (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 circulating air
return feed

Cold air distribution

A KR 65 Ø 65 mm (10) cold air duct with at least one outlet
must be connected to each of the three cold air emitters of
the unit (7, 8 and 9).
Slide the cold air ducts (10) into the cold air emitters of the
unit and route to the air outlet nozzles. Truma can supply a
muffler for installing in the cold air system (part no. 40040-
60100) as a accessory for reducing the amount of noise.
The SCW 2 swivel air outlet (black – part no. 39971-01 or
beige, part no. 39971-02), end piece EN-O (part no. 40171-07)
with lamella inset LA (part no. 40721-01/02/03/04/05) or the
RL rectangular air outlet (part no. 40280-01) with the ANH
connecting piece (part no. 40290-02) have proven to be suit-
able for emitting the cooled air into the interior of the vehicle.
Important notes
The cold air distribution system is individually designed for
each vehicle model using a modular principle. A wide range of
accessories is available for this purpose.
In order to achieve the best possible cooling power, we
recommend:
–
Route cold air pipes to air vents 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 pipe (max. 8 m) to the
right-hand cold air outlet (9), since this has the most air
throughput.
– To prevent condensation in the cold air ducts, do not route
pipes anywhere near heat sources (e.g. power supplies or
behind the refrigerator).

Circulating air return

The circulating air is sucked in again by the device, either
through an additional air grille (1 – accessory, part no. 40040-
29200), for example in the wall of the stowage compartment,
or via a number of smaller apertures with a total surface area
of at least 300 cm².
Important note
To ensure trouble-free air exchange, the air infeed from the in-
terior of the vehicle to the installation location must be located
in the immediate vicinity of the device. If appropriate, covers
are to be fitted, in order to avoid the circulating air return be-
ing impeded by stowed objects.
If the equipment cannot be installed in close proximity,
Truma can provide a flexible air intake (part no. 40090-
59100) as an accessory.
