3.5.2 Condensation and heat insulation
on ducts connected to the unit is especially important. All ducts installed in cold rooms/areas must be well insulated.
Use insulating covering (minimum 100 mm mineral wool) with plastic diusion barrier. In areas with extremely low
outdoor temperatures during the winter, additional insulation must be installed. Total insulation thickness must be at
least 150 mm.
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
3.5.3 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
itself, installation of silencers before every inlet diuser is recommended.
3.5.4 Electrical connections, components
All electrical connections are made in the electrical connection box which can be found on the long side of the unit.
The hatch is removed by unscrewing one screw (gure 7).
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 (chapter
3.5.5).
Danger
• Make sure that the mains power supply to the unit is disconnected before performing any
maintenance or electrical work!
• All electrical connections must be carried out by an authorized installer and in accordance
with local rules and regulations.
Warning
• The units electrical connection to the mains power supply must be preceded by an all pole
circuit breaker with a minimum 3 mm gap.
