Caution
• If the unit is installed in a cold place make sure that all joints are covered with insulation, and tape well
• Duct connections/duct ends should be covered during storage and installation
• Do not connect tumble dryers to the ventilation system
4.7.1.3 Silencers
To avoid fan noise being transferred via the duct system, silencers should be installed both on supply and extract air.
To avoid noise being transferred between rooms via the duct system and also to reduce noise from the duct system it-
self, installation of silencers before every inlet diffuser is recommended.
4.7.2 Electrical connections
All electrical connections are made in the electrical connection box which can be found on the long side of the unit. The
electrical box can be tilted for easy access by loosening the grip screw (figure 9, pos 1). The hatch is removed by un-
screwing four screws (figure 9).
The unit must not be put into operation before all the electrical safety precautions have been read and understood. See
the enclosed wiring diagram for internal and external wiring.
All external connections to possible accessories are made to terminals inside the electrical connection box (table 3).
