Installing The Air Conditioning Unit - Truma Saphir vario Instrucciones De Uso

The air conditioning unit is attached to the floor, which must
be level and smooth. The air inlet (LE), the air outlet (LA) and
the muff (3) may need to be fitted with additional gaskets if
the unit is attached to a grooved floor. The room air which is
to be cooled is drawn in directly by the device via an addi-
tional air grille in the stowage box wall (1 – Accessory part no.
40040-29200) or via other apertures with a total surface area
of at least 300 cm².
The circulated air will be purified and dried while the
unit is in operation. Accordingly, if the unit is installed
in external stowage containers (e.g. double bottoms) suit-
able steps must be taken to ensure that the air which is to be
cooled is extracted from the interior of the vehicle. The suction
intake of air from the outside can severely impair the effect of
the air-conditioning system.
If possible, position the unit so that the frame of the vehicle is
between the air inlet (LE) and the air outlet (LA).
Place the installation template into the stowage box that is
intended for installation and check the space situation for the
floor openings. The air conditioning unit must have minimum
clearance of 25 mm from the walls at all sides in order to
avoid noise transmission during operation.
The openings in the floor of the vehicle must be freely
accessible, and must not be blocked by frame sections
behind them or the like! The openings must not be within the
range of the wheel spray. Spray guards must be fitted if
necessary.

Installing the air conditioning unit

Decide whether the air outlet channels are to exit from the
side or the front. Position the air outlets on the air conditioning
unit accordingly.
Place installation template in stowage compartment and fix in
position. Mark mounting holes for the 4 front, rear and side
retaining brackets (2).

The legs of the side retaining brackets (2) should point out-
wards in order to make the unit easier to detach from the false
floor (if necessary)!
Mark floor opening "LE" for the air supply, "LA" for the
outgoing air and "KO" for the condensation drain.
Remove template and cut out the marked floor openings.
Before drilling, always check for underlying / concealed
cables, gas lines, frame sections and the like!
Then seal the edges of the openings in the floor of the vehicle
with underbody protection.
Screw down the 4 retaining brackets (2) using 3 screws per
bracket.
Insert muff (3) for condensation drain (KO) from above.
Place air conditioning unit in stowage compartment (between
the 4 retaining brackets).
When installing the unit, please ensure that the
muff (3) 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 provide
good air circulation, the openings in the bottom of the
unit and the floor must align exactly. Correct operation
of the unit cannot be guaranteed unless this is the case!

Hook the two clamping straps onto the 2 side retaining brack-
ets (2) and route the clamping straps around the air condition-
ing unit as securely as possible and secure with the Velcro
fastener.
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).
Seal muff (3) for condensation drain all round from below
using body sealant.
Attach the two floor grilles (4) for LE and LA to the floor of
the vehicle from below with suitable screws or clips (not
provided).
