Operating and Care
Description
The cooling unit is a part of the air handling unit and
should be installed as a module in the EU air handling
unit.
The cooling unit operates independently and has its
own cubicle; however cooling capacity must be swit-
ched in according to signals from the air handling unit.
The cooling unit is designed for cooling the supply air in
the temperature range of b20 – +32 °C. It is
possible to lower the supply air temperature by 9 – 16 °C
depending on the selected capacity variant, air tempe-
ratures and air volume ratio: supply air/extract air.

An electric equipment cubicle is installed in the service
section of the cooling unit. The cubicle contains mainly
the following items of equipment:
– Main switch
– Control circuit fuse
– Protective motor switch
– Control unit with display
