6. INSTALLATION
DO NOT MISS!
•
The connected pipes must be of the same diameter as the ex-
haust and suction necks. If pipes of a smaller diameter will be
used, the unit performance could drop and in some cases the
lifespan of the ventilators could also decrease.
•
Any joints between the air distribution pipes and the unit
must be sealed using a sealant or a sealing tape.
•
The minimum distance of the bent air pipes or adapting pie-
ces from the unit neck should be 500 mm.
6.3-2 Protective grid
In the event that some of the necks of the unit will not be used
for connecting pipes, it is necessary to fix the opening with a
grid for protection from touching the rotating parts of ventilator,
heater bars etc..
