Mounting and set-up
Make sure that the installation location provides for suffi
cient space as required for the unit
maintenance.
The units are suspended to the ceiling by means of belts rigidly fastened to a horizontal surface (Fig.
3) or threaded rods screwed into dowels which are buried into the ceiling. Prior to the installation check
the unit casing for any left-over foreign objects such as plastic fi lm or paper.
For best operation effi
ciency the unit should be preceded and followed by straight duct sections at
least 1 m in length.

Condensate drainage
The condensate drain pan located in the heat exchanger section is equipped with condensate
drain pipes which lead the water away from the unit.
Connect the drain pipe (1), the U-trap (3) (not included in the standard delivery set) and the
sewerage system (5) with metal, plastic or rubber pipes (2) and (4). The pipes must be installed at
the minimum gradient of 3°. Prior to connecting the unit to the power mains prime the system with
water! The U-trap must be fi lled with water at all times! Check for any obstructions to the free fl ow of
water into the sewerage system to prevent condensate accumulation inside the unit during the heat
exchanger operation which, in turn, may cause equipment failure and water ingress into the premises.
