KOMFORT Ultra D105-A
MOUNTING
Due to the compact casing size the unit is designed for horizontal mounting
behind false ceiling and connection to Ø 125 mm air ducts.
The unit is suitable for mounting in engineering and service premises as well
as living and lounge areas.
The installation place must have connection to the sewage drain system.
While planning the ductwork layout avoid too long air duct sections,
numerous bends and reducers because it may reduce air flow.
The mounted air ducts must not be deformed.
Provide airtight connection of the air ducts to the unit spigots and fittings.
While mounting consider the need to ensure sufficient service access to the
unit.
The minimum distance between the unit and a surface on servicing side is
shown in fig. 3.
The unit is suspended to the mounting surface using a threaded rod fixed
inside of the threaded dowel.
The unit mounting position must provide condensate drainage and access to
the terminal box for electric connection and access to the service panel for
maintenance and filter replacement.
While mounting install a ventilation grille, an outer hood, a disk valve or any
other protecting device at outlet from the air duct with a mesh width not
exceeding 12.5 mm.

Safety precautions:
The unit must be mounted to a rigid and stable structure.
The unit must be suspended using anchor bolts. Before starting mounting check that the mounting structure has sufficient
loading capacity for the unit weight, otherwise reinforce it with beams, etc.
If the fixing rods are too short it may result in resonating with ceiling. To prevent resonance problem use fixing rods with a
sufficient length.
If the spiral air duct connection point is supposed to be the source of noise generation replace the spiral air duct with a
flexible one. The flexible connectors are also recommended for noise absorption.
