Bypass For Kitchen - Swegon CASA W4 Smart Installation, Operation And Maintenance Instructions

be connected to an electric socket at an easily acces-
sible spot. For power required, see the Section entitled:
"Technical data".
On top of the ventilation unit are two modular cables
for control of the unit. The maximum connected length
of the modular cable in the system is 40 metres. If you
lengthen the modular cable within some building ele-
ment (e.g. in a wall), you should lengthen the cable in a
∅ 20 mm conduit, anticipating a possible later change
of cabling.
When installing the unit, make sure that you provide
adequate access to the connector of at least one cable,
e.g. for servicing and adjusting the unit, if and when the
need arises.
In multi-storey buildings, a control panel can be used as
a so-called hand-held micro terminal in conjunction with
service and installation work.
The connection of possible accessories is described in the
wiring diagram in the Section entitled: "Technical data".
The cables for accessories are not included in the supply.
! Important
If any further electrical wiring is required,
only a qualified electrician shall be allowed
to carry out this work.
The electric and control cables are located
on the upper side of the ventilation unit.
Make sure that the electric cable can be con-
nected to a wall outlet without obstruction.

2.6 Bypass for kitchen

The cooker hood is usually connected to the ordinary
extract air duct. However the cooker hood can be
connected to the ventilation unit's separate extract air
connection, in order to meet national regulations or for
achieving a more effective than normal extract airflow.
The extract air from a compatible Swegon CASA cooker
hood can be conveyed via a duct to an extra duct con-
nection on the top of the ventilation unit. The duct be-
tween the cooker hood and the ventilation unit must be
installed in such a way that makes it possible to clean it.
The ventilation unit can be controlled from the cooker
hood control panel.
Swegon reserves the right to alter specifications.
!
The bypass for a kitchen is intended for use
when the airflows from the cooker hood/
kitchen are boosted. The kitchen's general
ventilation must take place via the extract
air duct. If the general ventilation takes
place continuously via the cooker hood, the
supply air and extract air flows through the
heat exchanger will be out of balance, and
this will lower the efficiency and impair
the ventilation unit's anti-freeze protection
functions during the winter.
