2. Installation
2.1 Ventilation unit installation site
The temperature in the space where the unit will be
installed must be more than +10 °C. The ventilation unit
can be installed in a machine room, store room, etc.
where there is a drain.
The ventilation unit should not be secured to a wall that
borders to a living room or a bedroom due to the risk of
noise.
During installation, arrange electric and control cables to
make them easily accessible.
The ventilation unit is mounted on the floor, on the base
included in the delivery.
2.1.1 Mounting on a base
The ventilation unit’s base is mounted horizontally by
using the adjuster feet. In order to facilitate lifting the
ventilation unit onto the base, the heat exchanger can
first be dismantled from the from the ventilation unit.
When the ventilation unit stands on the base, you
can, in order to fasten the condensate discharge hose,
loosen the front edge screws.
2.2 Condensate discharge
Connect the discharge hose to the ventilation unit’s
condensate discharge connection (3/8” male threads).
There are two condensate discharge connections on
the ventilation unit, as the ventilation unit is available
in both right and left designs. On delivery, one of the
condensate discharge connections is plugged inside the
unit. The condensate discharge hose is connected to the
open connection.
The condensate discharge water must be channelled
to a floor drain or the like using a hose or tube with 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.
Hose to lead off the condensate is included in the deliv-
ery of the ventilation unit. The hose has a ready-made
loop that serves as a water trap.
There is a metal water trap available as an accessory
(UVLL).
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.
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 con-
densing 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.
2.4 To seal around duct penetration collars
It is advisable to use a mounting frame for sealing the
moisture barrier in the attic tie beams.
It is important to the preserve the tightness of the
vapour barrier at the duct penetration collars. A building
element penetration seal (accessory) will facilitate this.
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”.
