the side panels with holes at the back are interchangeable.
5.6.2
Connection of the ducts
Correct installation of the channels should comply with the following recommendations:
- the size of the ducting must be at least the size of the supply outlet and suction inlet on the unit. It is preferable to
enlarge the ducts near the machine made in accordance with the rules of good practice;
- the ducting must be connected to the unit by interposition of an anti-vibration coupling in order to reduce
transmission of vibrations from the unit to the ducting;
- always seal the joints so as to prevent air escaping from the channels;
- avoid making the ducts make sharp bends or branches in the immediate vicinity of the unit, in particular as
regards the air delivery duct where two coupled fans are installed.
- if the noise transmitted by the machine through the channels needs to be considerably reduced, these must be
fitted with special silencers. The pressure drops along them must be considered when calculating the required
available external head pressure.
- if the unit is equipped with a direct exchange heat generator, the supply channel must be provided with a special
fire damper as laid down by current regulations.
We reserve the right to make changes without any prior notice.
