INSTALLATION OF THE BREATHER LINE
Installing the breather line towards the outside
Mount the silencer at the furthest point of the line
in order to absorb as much noises as possible (see
paragraph “Planning of the breather pipe” on page
8).
It is not advised to use too many sweep ells which
could slow down the expulsion and consequently
reduce the motor performances.
It is advised that the last meters (max. 5 m) of the
breather line have a piping with a larger Ø in
comparison with those of the pipes used for the
vertical column. (see pages 8-9).

Installation scheme of the backup box with
straight fitting.
The backup boxes must be installed flush with the
plaster and it must be positioned perfectly in an
horizontal position.
The chases on the wall change according to the
inlet socket that one intends to install:
•
Disan rectangular backup box code SD101/SD102
minimal depth (p) = 70 mm
minimal width (l) = 125 mm
minimal height (h) = 125 mm
•
Disan square inlet valve code SD501/SD502
minimal depth (p) = 65 mm
minimal width (l) = 85 mm
minimal height (h) = 140 mm
