3.3 Location

To achieve optimal operating economy it is important to
design the duct system with as low a pressure drop as pos-
sible. Therefore the designer should focus on arranging
the duct runs as short as possible so that there will not be
more duct bends than necessary. The duct connections on
the Compact Air/Heat units are arranged to enable ducts
to be run in any direction without being in the way of one
another.
The design of the hoods, grilles, etc. for outdoor air/ex-
haust air are also important. The specially constructed
exterior wall hood for the Compact Air/Heat units is de-
signed in such a way that minimizes pressure losses.
Examples of alternative locations of the Compact Air/Heat
unit in a room are shown below.
Important! The air handling unit should be located
at least 400 mm on either side from a wall to avoid
acoustic problems. See the illustration below.
For the sake of comfort, the nearest workplace should be
1 metre from the unit. However note that at least 1,200
mm open space is required in order to be able to open the
inspection door.
In the case of a COMPACT Heat unit, make sure that you
provide open space in front of the air handling unit to en-
able long throw lengths when the unit is operating in the
BOOSTER mode (fl ow Boost).

400 mm

3.4 To Fit the Kick-protection Base

Secure the 6 screws supplied halfway into the tapped
holes on the base beam of the air handling unit.
Then fi t the side plates of the kick protection base (the
two short plates) by pushing the keyhole fasteners over
the screws from the front side of the unit. Now the side
plate should hang loosely on the screws.
Fit the front side of the kick protection plate (the long
plate) on the two screws on the front side. Now the front
plate should hang loosely on the screws.
Adjust the position of the plates and tighten the screws.
Fasten the cover plugs, supplied, in the holes over the
screws.
Important! If the unit is to be installed with its right-hand
or left-hand side near a wall (min. of 400 mm), the base
plate that is to face this way should be fi tted before the
unit is positioned at its fi nal location.

3.5 To Install the Air Recirculation Section/
Louvre Damper (applies to COMPACT Heat only)
The room temperature sensor supplied with the unit must
be mounted, see special instructions for the TBLZ-1-24-2
room sensor.
The air recirculation section and louvre damper are sup-
plied loose.
The damper actuator for the air recirculation section is
supplied resting on the extract air intake mesh on top of
the unit. This part must be mounted on the air recircula-
tion section's damper spindle as follows:
1. Remove the damper actuator from the mesh of the extract
air intake.
actuator while the air recirculation section is at fl oor level
before the former is mounted.
2. Disconnect the electric quick connector on the damper
actuator.
3. Secure the mounting rail by means of the screws provided,
in the redrilled holes on the air recirculation section. See
illustration.
3. Mount the damper actuator with the damper blade in the
outdoor air position, that is: the damper blade must be
located against the grille. See illustration.
4. Tighten the screws holding the damper actuator with the
clamp on the damper spindle. Set the actuating direction
according to the direction arrow towards 0. See illustration.
5. Mount the air recirculation section on the top side of the air
handling unit for outdoor air and connect the electric quick
connector.
6. Fit the louvre damper on the top side of the air handling
unit for exhaust air.
Clamp for the damper spindle must be in this position
Actuating direction in Position 0
Damper blade must be in the outdoor air position (grey-shaded)

3.6 Duct Connection

Connect 250 mm dia. spiral ducts to the outdoor air and
exhaust air connections on the top side of the air handling
unit.
Run the ducts through the external wall and have the duct
end edge-to-edge with the façade of the building if Sw-
egon's external wall hood is used.
The ducts can also be run through the ceiling (the ducts
for the COMPACT Heat cannot be run straight up from
the air handling unit. However this makes more compli-
cated modifi cations necessary and among others places
greater demands on sealing around the arrangement to
achieve air tightness.
The ducts must be insulated with at least 30 mm thick
insulation and be provided with a damp-proof outer layer.
