II.2.
Space required for maintenance
Generally speaking, it is desirable to provide access space of at least the width of the unit on the access side for maintenance.
More specifically for the Pyrostar range, an extra 200 mm free space is needed on the opposite side to service side.

II.3 Installation
The unit must be laid on a sufficiently rigid and flat surface (use vibration mounts if necessary).
Install the unit such that bad weather or ambient temperature cannot damage the internal items of the unit during installation as well as when
used later (possibly provide a protective cap).
F400-120 fans should be installed outdoor or, when installed indoor, separated from other volumes by a 1 hour fire-resistant wall. The door of the
technical room should be ½ hour fire resistant. Ventilation of this technical room should comply with the installed materials.
F400-120 fans should be wired to a converter only in Comfort mode and run at full speed when extracting smoke.
If the motor is equipped with overheat protection, they should be wired to the converter so it can protect the motor during Comfort mode.
