A normal installation can be carried
out when the connecting duct is below
the ceiling. Rear connection.

 

 

A high connection or a low ceiling means
that the connecting duct is above the ceiling
height. If you have access to the space above
the ceiling you can use a standard unit, if not
you must use a cleanable adjusting damper.

When you connect an LKB from the front you
normally have a false ceiling or duct cover.
In this case it is recommended to use a cleanable
adjusting damper in the duct system.
