Pre-assembly of air distribution panel
The rocker switches and the setpoint potentiometer (if applicable) must be installed in the air distribution
panel, depending on the version and scope of supply concerned.
Installation of the rocker switches:
Locate rocker switches in rectangular cut-outs of air distributor panel so that they engage (Fig. 4.5).
Installation of the setpoint potentiometer:
Insert the setpoint potentiometer in the hole in the air distribution panel as shown in Fig. 4.5.
The wiring harness is prepared for connection to the command value switch potentiometer (mechanical).
Simply pull on connector housing to unplug the connector. By pulling on the cable loom the terminal plug
is arrested (self-locking).
NOTE
The light conductor must make contact with the rotary selector.
Installation of air distribution panel
a)
Prepare the air duct frame (if necessary) so that it creates an effective seal on all sides and the top
of the intake and delivery area between the vehicle roof and the intermediate roof.
b)
Secure the air duct frame to the roof. Ensure that the fitted roof-top air-conditioning system is not
damaged when drilling holes.
c)
Connect cables between the air distribution panel (S1 and S4 in circuit diagram, Fig. 3.1 or 3.2) and
the baseplate.
d)
Position the air distribution panel as shown in Fig. 4.4 and secure it with ten self-tapping screws to
the intermediate roof or to suitable self-made brackets if necessary. If the optional recirculating-air
filter has also been ordered, it must be inserted in the intake area of the air distribution panel.
