BASIC INSTALLATION RULES
There are three versions of PRANA 340S ventilation
systems:
• Internal version;
• Wall version;
• Combined version (the system is mounted in the plane
of the wall on the other side can have round or flat ducts for
connecting ducts).
In the internal version of the ventilation system it is
mounted under the cealing on in a wall.
In the wall and combined version, the ventilation system is
mounted in a wall opening of the appropriate diameter.
There are restrictions on the length of the operating
module, so you must specify the thickness of the wall
(required for installation) when making an order.
The mounting of the system in the internal version is made
to a solid and stable surface.
The fixing of the PRANA 340S system to the wall must be
made through vibration absorbers to avoid transmitting any
minor vibrations to the ceiling or the wall.
The connection of the ducts to the ventilation system must
be made through vibration-absorbing inserts to eliminate
the transmission of vibration to the ducts.
