Indoor air outflow
This unit was designed for the use of KR 65 cold air ducts
(10), dia. 65 mm. The ducts must be secured to the device
with screws (11).
The cold air duct must be connected to all three apertures,
with at least one outlet.
Important note
The cold air distribution is designed for each vehicle type
individually, on the modular princible. A wide range of acces-
sories is available (see page 10).
To achieve the best possible performance, we recommend
that:
1. The air outlets be fitted in the upper part of the vehicle
(see installation example on page 2).
2. A maximum of 15 m cold air ducting to be used.
3. Lay the ducts as short as possible and in a straight line to
the air outlets.
4. To avoid condensation water, do not lay the ducts in the
vicinity of sources of heat (e.g. behind refrigerators).
Indoor air return
The indoor air is sucked in again by the unit, either through
an additional grille (12 – special accessory part), for example
in the wall of the stowage compartment or via a number of
smaller apertures.
The unobstructed return air opening must not be less
than a minimum of 300 cm².
Electrical connection 230 V / 240 V
The 230 V / 240 V electrical connection must always be
made by an expert (in accordance with VDE 0100,
part 721 or IEC 60364-7-721, for example, in Germany). The
information given here is not intended as instructions for you
to carry out. It is for assisting the expert assigned to carry out
the job, acting as auxiliary information when connecting the
appliance!
Establish the connection to the mains with the connection ca-
ble, 150 cm long, to a lead in the vehicle, fused to at least 10 A.
Always pay attention to connect carefully with the correct
colours!
For maintenance and repair work a disconnecting device must
be provided on the vehicle for all-pole disconnection from the
power supply, with at least 3.5 mm contact clearance.
Function check
After installation, check all functions of the unit as specified in
the operating instructions.
The operating instructions must be handed to the owner of
the vehicle.
