1 GENERAL
1.1 Field of Application
The COMPACT Air and COMPACT Heat units are complete
air handling units that can be installed directly in the room
to be ventilated. The ducts for outdoor air and exhaust air
should be connected to the top of the unit and should be
arranged to lead out through the wall. Other than that,
you need only connect the unit to the mains electric supply.
The installation work can be carried out very quickly and
easily and if the task of cutting openings through the wall
is not complicated, the unit can be operational in just a
few hours. It is also simple to relocate the air handling
unit if the nature of the activities conducted in the room
changes.
The ventilation is very effective thanks to the displacement
air distribution method used. The built-in control equipment has several functions for economic operation.
The COMPACT Air and COMPACT Heat units are designed
for comfort ventilation and can be used in classrooms, day
nurseries, conference halls, smaller offi ces, workrooms,
shops, restaurants and similar public premises.
The difference between the COMPACT Air and the COMPACT Heat units is that the COMPACT Heat units can also
be used for heating.
It is important keep all the special characteristics of the
air handling units in mind when planning them into the
project, installing, adjusting and operating them to fully
obtain all the benefi ts the COMPACT system has to offer.
The unit must be installed indoors.
Important!
Always read the safety precautions in Section 2 that
explain the risks involved in running the unit and
designate who shall be permitted to operate and
service the unit, and carefully follow the installation
instructions provided in each paragraph.
The product identifi cation plates are located inside the
room unit and on the unit’s rear side. See Sections 1.5.1
and 1.5.2 respectively. Refer to the particulars on the
product identifi cation plate when you contact Swegon.
1.2 Mechanical Design
The COMPACT is available in one physical size and for two
airfl ow ranges.
Its sheet steel exterior is painted white, NCS S 0502-G.
The decorative strips and cover plate around the control
display are dark grey, NCS S6010-R90B. The inner skin is
predominantly made of aluminium-zinc plated sheet steel.
The casing has 30 mm thick intervening mineral wool
insulation; the inspection doors have 50 mm thick insulation.
The COMPACT Air and the COMPACT Heat are equipped
with pleated, Class F7 fi lters.
The type RECOnomic rotary heat exchanger is variable
speed controlled and has a peak temperature effi ciency of
85%.
The supply air and extract air fans are direct-driven plug
fans. The fans are equipped with EC motors that provide
high effi ciency across the entire operating range.
1.3 Control System
The IQnomic control system is microprocessor-based and is
integrated into the unit. It controls and regulates the fans,
heat exchanger, temperatures, airfl ows, operating times
and a large number of internal and external functions as
well as alarms.
1.4 Environmental Documentation
Environmental Documentation with the Dismantling
Instructions for recycling and the Environmental Declaration can be downloaded from our home page: wwww.

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 supplied 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 recirculation section’s damper spindle as follows:
1. Remove the damper actuator from the mesh of the extract
air intake. It is advisable to mount the damper
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.
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 Swegon’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 complicated 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.
3.3 Location
To achieve optimal operating economy it is important to
design the duct system with as low a pressure drop as possible. 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/exhaust air are also important. The specially constructed
exterior wall hood for the Compact Air/Heat units is designed 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 enable long throw lengths when the unit is operating in the
BOOSTER mode (fl ow Boost).
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.

3.7 Exterior Wall Hood
The CACZ-1-03 External wall hood accessory is specially
designed for low pressure drop and for preventing shortcircuiting between the outdoor air and the exhaust air.
The standard hood is painted grey black, NCS 8502-B. See
special instructions.
3.8 Existing Ventilation
The existing ventilation in the room for supply air and
extract air should be blanked off or sealed. This is an
important prerequisite for satisfactory ventilation and heat
recovery.
3.9 Serving More than One Room
The COMPACT Air units are designed for installation and
connection according the instructions in Sections 3.3, 3.6
and 3.7.
Swegon recommends this procedure.
Nevertheless it is possible to completely or partially take
extract air from adjacent rooms or also to ventilate a space
other than the room where the air handling unit is standing.
The problems, which one must observe in this case, are
specifi ed below. Always engage the services of a professional in this fi eld.
3.9.1 Extract Air Intake
If the extract air is completely or partially taken from an
adjacent room, note that the duct pressure drop must not
exceed available pressure.
Also note that the supply air temperature is regulated in
relation to the extract air temperature. If the extract air
comes from another room with a different temperature,
the temperature of the supply air may cause short-circuit
airfl ows or give rise to draught problems. Pay special attention to where the extract air sensor is located.
3.9.2 Transfer Air
Transfer air grilles to adjacent rooms have a strong infl uence on the system’s performance.
Air transfer grilles positioned low, cause the transfer of
”unused” air to adjacent rooms and impair the ventilation
performance in the room where the unit is installed.
Air transfer grilles positioned high involve the risk that
”used” air will be transferred to adjacent rooms. Ventilation is however not impaired in the room where the unit is
installed.
Important! If the doors are open, the adjacent room will
also be ventilated due to the displacing air supply.
3.10 Connection to the Electric Power Grid
The COMPACT air handling unit is supplied with a power
cable with mains plug, from the factory.
COMPACT Air
Cable: 3 x 1.5 mm2. Mains plug, 10 AT, single-phase 230V.
COMPACT Heat
Cable: 5 x 2.5 mm2. Mains plug, 5-wire Perilex, 16 AT,
3-phase 400V.
Important! The power supply connection to the COMPACT Heat unit is not of an electrical safety design that
prevents children from inserting objects into the socket. It
is recommended that it be positioned 2 metres above the
fl oor above the air handling unit by the duct connections
for instance.
If the air handling unit is instead to be connected with a
fi xed extension, an external main switch must be fi tted.
3.11 To Connect External Cables
The electrical cubicle in the COMPACT Air and the COMPACT Heat units is located by the heat exchanger. When
access to the control unit is required, the safety guard
in front of the heat exchanger must fi rst be dismantled.
When access to the power unit is required, the cover plate
in the unit’s extract air duct must fi rst be dismantled.
Cables from external sources can be run into the air handling unit through the rubber diaphragm by the extract air
intake, located on the top of the unit.
The external cables can be extended in the existing cable
protection together with the power supply cable in the
extract air duct of the unit. Insert the cable in the opening
in the end of the cable protection or press it in between
the cable protection and the insulation.
Cables can be run in to the electric cubicle according to
appropriate hole instructions in the rubber diaphragm.
N.B.! Cables for external communication outside the air
handling unit must be arranged at a minimum distance of
100 mm from any current-carrying (live) cable.

3.12 To Adjust the Supply Air Discs
The positions of the supply air discs can be adjusted after
dismantling the front grille of the lower section of the
unit. Use a 6 mm Allen key. The screws are located within
the outer holes in the corners.
When the front grille has been removed, the air discharge
direction of the front discs can be adjusted from the
backside of the front grille. Turn the discs by hand to the
appropriate setting.
The side discs can now also be adjusted without any further dismantling. The discs are accessible by putting your
hand inside the air handling unit.
Air handling unit viewed from above.
The front discs and side discs are
shown from this view below.
The factory-preset supply air distribution pattern and two
examples of possible modifi ed distribution patterns are
shown below.
Since each disc is individually adjustable, the possibilities
for modifying the air distribution pattern are practically
endless.
The arrows shown above
indicate the position of
each disc.

8.3 Switch clock
Basic functions for the switch clock can be preset
at INSTALLATION LEVEL under FUNCTIONS/OPERATION and the values can be read and set at USER
LEVEL.
TIME/DATE
The current date and time can be set and adjusted whenever
required.
The switch clock automatically takes leap years into consideration.
Automatic changeover between summer time/winter time to EU
Standard has been preset.
This changeover function can be blocked at INSTALLATION LEVEL
under FUNCTIONS/OPERATION
.
TIME CHANNEL
Times and days can be set when the unit is to run at high speed,
low speed or be stopped.
Eight different time channels can be set. If the same in-operation
times are to apply every day of the week (Mon-Sun), you need
only program one time channel. Different operation times for
each day of the week can be programmed by programming a
time channel for each day (Mon-Fri, Sat-Sun or Mon, Tues, Wed,
etc)
The time can be set as 00:00-00:00 if the deviating in-operation
period is desirable for the entire 24 hours period.
YEAR CHANNEL
The year channels make it possible to set deviating in-service
times for parts of the day during certain parts of the year. Eight
different year channels (yearly time schedules) can be set. The
year channels over-modulate the time channel during the hours
of the day and the days that the year channel is active. The year
channel dates indicate the dates between which the year channel shall apply and the year channel hours indicate the hours of
the day between which the year channel will steer the controller
to operate the rotary heat exchanger at a specifi ed speed. Other
times within the year channel still apply to that time channel.
The time can be set as 00:00-00:00 if the deviating in-operation
period is desirable for the entire 24 hours period.
Functions for summer night cooling, prolonged operation, etc.,
operate also when the year channel is active.
8.4 Filters
(and anti-frosting function of rotary heat exchanger)
There are two types of fi lter monitoring:
Calculated fi lter monitoring (preset at factory) monitors the fan’s
speed increase conditional on the degree of fouling in the fi lter.
The calibration involves taking airfl ow and fan speed readings.
An alarm is initiated when the fan speed has increased by 10%
above the preset alarm limit.
Filter monitoring with a pressure sensor (accessory) measures
the pressure drop across the fi lter. The alarm limit is preset in Pa.
8.4.1 Readings
When reading the fi lter status, the fi rst value shows current value
and the second value shows current alarm limit.
8.4.2 To Calibrate the Filters
The fi lters must be calibrated for the fi rst time during commissioning, when the duct system has been installed and adjusted.
After that every time fi lters are replaced.
Calibration should be activated for both the supply air and the
extract air if both fi lters are changed or for only for one airfl ow
direction if only one fi lter has been changed.
When fi lter calibration has been activated, the unit runs at high
speed for about 3 minutes.
After the fi lter has been calibrated, a speed increase of 10%, or
a pressure rise (= fouling of the fi lters) of 100 Pa is permissible,
after which an alarm is initiated indicating a fouled fi lter.
The alarm limit can be changed at INSTALLATION LEVEL under
ALARM SETTINGS.
8.4.3 Calibration - Rotary Heat Exchanger
If the anti-frosting function accessory for heat exchanger is installed (see 10.6.1.1) calibration can be selected from this menu.
When calibration R-HX is activated the fans are accelerated to
high speed for about 3 minutes.
