4.3 Condensation drain
The unit must be connected to the condensation drain. A transition, tube and drain trap are enclosed upon delivery.
Connect the drainage on the units exhaust side (pos 2, figure 4). The drainage on the supply side (pos 1) must be con-
nected if the unit will be used with cooling equipment or if it will run extensively where the outdoor climate is very hu-
mid. On left hand units the positions of the connection are reversed.
See table 1 how the height “H” corresponds to different maximum negative pressures.
If the unit is mounted in a tight area that makes it difficult to have the appropriate height, a pump is available as an
accessory.
Note:
When installed in a non heated place the drain pipe and trap needs to be insulated well to prevent the water
from freezing.
Note:
If drainage is used on supply air side the stickers most be removed, figure 3. On left hand unit the stickers
are on the opposite side.

4.7.2 Condensation and heat insulation
Outdoor air duct and exhaust ducts must always be well insulated against condensation. Correct insulation installation
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 diffusion barrier. In areas with extremely low out-
door 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
4.7.3 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.
4.7.4 Electrical connections, components
