2.1.4 Swegon CASA cooker hood separated from
the ventilation unit
The compatible Swegon CASA cooker hood can be
mounted separately from the ventilation unit, and in
that case the extract air is conveyed from the cooker
hood to an extra duct connection on the upper side of
the unit. The duct between 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.

Important
The 100 mm duct connection from the ven-
tilation unit should be fitted with a taper
piece for transition to 125 mm as near to
the unit as possible.

2.2 Condensate discharge

As a rule, no condensate discharge connection is
needed under dry ambient conditions and in combina-
tion with a rotary heat exchanger. A certain humidity
load exists in homes and a condensate discharge line
should be connected to the ventilation unit, if consider-
able moisture is produced in the home.
Connect the discharge hose to the ventilation unit's
condensate discharge connection (3/8" male threads).
The condensate must be channelled to a floor drain,
the water trap of a sink or the equivalent by means of
a tube or a pipe having an inner diameter of at least 12
mm. The tube must not be connected directly to the
sewer. The tube must not have a second water trap or
be run horizontally. The damming height of the water
trap should be at least 100 mm.
The condensate discharge connection is plugged
from the outside of the ventilation unit.Remove the
plug when you begin using the condensate discharge
connection. Check that the condensate discharge outlet
is not clogged and check its outflow by pouring water

on the bottom of the ventilation unit. The condensate
discharge connection is located on the rear of the unit
under the rotary heat exchanger.
The hose for removing condensed water is available
as an accessory (part number 502103). The hose has a
ready-made loop that serves as a water trap.
There is a metal water trap available as an accessory
(UVL).

2.3 Ducts

Install the ventilation ducts, sound attenuators, sup-
ply air diffusers, air intake grilles and exhaust air ducts
as shown in the ventilation drawings. To prevent the
propagation of sound, do not install the ducts directly
against structural building elements.
Insulate the ventilation ducts in order to reduce loss
of heat or cooling energy and to prevent water from
condensing on surfaces. In addition, it is advisable to
insulate the ducts to prevent the spread of fire. It is of
greatest importance to insulate cold ducts without
gaps in the insulation, so that moisture cannot
condense.
! Important
Check whether the ventilation unit has
been supplied in the right-hand or left-
hand version to make certain that you are
connecting the ventilation ducts to the
correct duct connection spigots on the unit.
Check the ventilation plans to make sure
that the duct connections are correctly in-
stalled. See also the dimensional drawings
in the Section entitled: "Technical data".

2.3.1 Commissioning the bypass for the kitchen

The ventilation unit has extra duct connections for
extract air from the cooker hood on its top and bottom
sides. The extract air from the cooker hood flows di-
rectly out through the unit's extract air fan and does not
