HOME VENTILATION
Installation
Suitable installation locations are a laundry room, storage
space, attic etc. If the ventilation unit is located in a cold
space, it should be have thermal insulation, if required.
Secure the ventilation unit vertically to the wall using the
wall mounting bracket supplied with the unit. The wall
structure must be able to support the weight of a 78
kg ventilation unit. It is also possible to mount the unit
against the ceiling with a ceiling mounting frame, avail-
able as optional equipment.
The unit has an extra duct connection for extract air on
its upper side. The extract air from the cooker hood flows
directly out via the extract air fan of the unit and does
not pass the heat exchanger. The connection not used
should be blanked off by a cover or an end piece for spi-
ral ducts (not included in the supply). The extract air from
the kitchen should not be extracted via the cooker hood,
since this airflow bypasses the heat exchanger.

Installation alternatives

1. The Premium cooker hood connected via duct to
the ventilation unit
The extract air from the Premium cooker hood is con-
veyed via a duct to an extra duct connection on the
top of the ventilation unit. The ventilation unit can be
controlled from the control panel of the cooker hood or,
if required, also from a separate control panel.
2. Separate controllable cooker hood
The extract air from the controllable cooker hood should
be connected to a separate power roof ventilator. The
ventilation unit is controlled from a separate control
panel. The best way to control the power roof ventilator
is from the cooker hood control panel.
