INSTALLATION
NOTE:
Before you install the ventilation unit,
make sure that there are no foreign objects in
the ventilation unit and duct system.
• Refer to the model-specific dimensional drawings
in the back of this manual for your specific
ventilation unit type.
• Inspect the order of duct connections to avoid
cross connections.
• Do not start the ventilation unit when it is installed
until the building is taken into use.
•
If the ventilation unit is started too early, the
ventilation system can be contaminated by
building dust.
• Make sure that the ventilation unit duct
connections are the same size as the duct.
•
Use a circular duct fitting to connect the unit
to the duct.
• Insulate the duct all the way to the unit casing.
