NOTE:
Necessary parts like control panel, supply air sensor, handles, drainage pipe with drain trap are placed
loosely inside the unit. The unit must not be put into operation before the enclosed parts are removed and
installed properly.
Warning
• The unit is heavy. Be careful during transport and mounting. Risk of injury through pinching. Use protective
clothing.
• Be careful so the unit don‘t tip over.
3 Installation

Fig. 2
3.1 Unpacking
Verify that all ordered equipment are delivered before starting the installation. Any deviation from the ordered equipment must be reported to the supplier of Systemair products.
3.2 Where/how to install
VSC are meant for indoor installation. The electronic components should not be exposed to lower temperature
than 0° C and higher than +50° C.
VSC must always be installed horizontally with the inspection doors downwards.
When choosing the location it should be kept in mind that the unit requires maintenance regularly and that the inspec-
tion doors should be easily accessible. Leave free space for opening the doors and for taking out the main components (chapter 2.2.2.)
NOTE:
If there is not sucient space to open the inspection doors, it is possible to mount rails and use existing doors as
sliding doors (accessory) chapter 4.6.
The outdoor air intake of the building should if possible be put in the northern or eastern side of the building and away
from other exhaust outlets like kitchen fan outcasts or laundry room outlets.
Warning
• The unit must be duct connected or in some other way provided with protection so that it is not possible to come
in contact with the fans through the duct connections

3.3 Condensation drain
The unit must be connected to the condensation drain.
See table 1 how the height “H” corresponds to dierent maximum negative pressures.
If the unit is mounted in a tight area that makes it dicult to have the appropriate height, a pump is available as an
accessory.
Note:
When installed in a non heated place the drain pipe and trap needs to be insulated well to prevent the water from
freezing.

3.4.1 Installation procedure
The units are designed for ceiling installation
Warning
• Beware of sharp edges during mounting and maintenance. Make sure that a proper lifting
device is used. Use protective clothing.
Warning
• The units electrical connection to the mains power supply must be preceded by an all pole
circuit breaker with a minimum 3 mm gap.
Danger
• Make sure that the mains power supply to the unit is disconnected before performing any
maintenance or electrical work!
• All electrical connections must be carried out by an authorized installer and in accordance
with local rules and regulations.
1)
Prepare the surface where the unit is to be mounted. Make sure that the surface is at, levelled and that it
carries the weight of the unit. Perform the installation in accordance with local rules and regulations.
Install the unit with 0-3° lean towards drainage connections.
2)
Li the unit in place.
3)
Connect the unit electrically to the mains power supply through the all pole circuit breaker (safety switch).
Led the wiring directly to the electrical connection box. Be careful not to cut the wiring.

3.5.2 Condensation and heat insulation
on ducts connected to the unit is especially important. All ducts installed in cold rooms/areas must be well insulated.
Use insulating covering (minimum 100 mm mineral wool) with plastic diusion barrier. In areas with extremely low
outdoor temperatures during the winter, additional insulation must be installed. Total insulation thickness must be at
least 150 mm.
Caution
• If the unit is installed in a cold place make sure that all joints are covered with insulation, and
tape well
• Duct connections/duct ends should be covered during storage and installation
• Do not connect tumble dryers to the ventilation system
3.5.3 Silencers
To avoid fan noise being transferred via the duct system, silencers should be installed both on supply and extract air.
To avoid noise being transferred between rooms via the duct system and also to reduce noise from the duct system
itself, installation of silencers before every inlet diuser is recommended.
3.5.4 Electrical connections, components
Danger
• Make sure that the mains power supply to the unit is disconnected before performing any
maintenance or electrical work!
• All electrical connections must be carried out by an authorized installer and in accordance
with local rules and regulations.
Warning
• The units electrical connection to the mains power supply must be preceded by an all pole
circuit breaker with a minimum 3 mm gap.
All electrical connections are made in the electrical connection box which can be found on the long side of the unit.
The hatch is removed by unscrewing one screw (gure 7).
The unit must not be put into operation before all the electrical safety precautions have been read and understood.
See the enclosed wiring diagram for internal and external wiring.
All external connections to possible accessories are made to terminals inside the electrical connection box (chapter
3.5.5).
