Only qualified personnel
Only qualified personnel should carry out
installation, configuration and commissioning.
Observe the following during
installation
The air heater for preheating is installed in the
outdoor air duct before the ventilation unit.
The air heater must be accessible without
obstruction. The air cooler must not be installed
in the immediate vicinity of the ventilation unit or
duct bends, as this will prevent an even air flow
across the cooler resulting in impaired output.

capped during transport, storage and installation.
