3.3 Installation recommendation regarding condensation
3.3.1 Condensation inside of the unit
When the unit is installed in a cold attic (close to outdoor temperature) the unit should run continuously. If the unit is in-
tended to be stopped by the user manually or due to calendar function we recommend to install air tight dampers at ex-
tract and supply air ducts. The dampers will ensure that no air circulates from the warm parts of the building through
the unit to outside (chimney effect). If no dampers are installed there is risk of condensation inside the unit and the out-
door ducts during these stop periods. It also might be that cold air from outside could pass the unit and enter into the
building. That could cause condensation outside the supply and extract air ducts and even at the valves in the rooms.
When the unit is not running due to late commissioning in winter time, the supply and extract air ducts should be dis-
connected and closed due to above mentioned effects until commissioning and regular operation.
254496 | v01

6| Delivery, Transport, Storage
3.3.2 Condensation outside of the unit
1. Room temperature 20°C
2. Room temperature 22°C
3. Room temperature 24°C
4. Room temperature 26°C
When the unit is installed in warm humid areas (like laun-
dry) together with low outdoor temperature there is a
certain point where moisture can condense outside of the
casing. The condensation relation to indoor relative hu-
midity, room and outdoor temperature is shown diagram
below. The condensation outside of the unit do not occur
in zones bellow each curve.
Important
Recommendation: If condensation occurs,
increase ventilation in area close to the unit.
Examples when condensation outside of the unit can
occur:
Example A: If the unit is installed in room where tempera-
ture is 22°C, outside temperature is –15°C, then dew will
start accumulating when relative humidity is 46% and
higher.
Example B: If the unit is installed in room where temperature is 20°C, outside temperature is –25°C, then dew will start
accumulating when relative humidity is 34% and higher.
4 Delivery, Transport, Storage
4.1 Transport and storage
The SAVE VTR 250/B should be stored and transported in such a way that it is protected against physical damage. It
should be covered so dust, rain and snow cannot enter and damage the unit and its components.
Important
• Use the packaging exclusively as transport protection and not as a lifting aid.
• Load and unload the air handling unit carefully.
4.2 Delivery/Unloading
The appliance is delivered in one piece containing all necessary components, wrapped in plastic on a pallet for easy
transportation.
Checking delivery
• Check the packaging and the air handling unit for transport damage. Any findings should be noted on the cargo
manifest.
• Check completeness of the delivery.
Verify that all ordered equipment is delivered before starting the installation. Any discrepancies from the ordered
equipment must be reported to the supplier of Systemair products.
Warning
When opening the transport packaging, there is a risk of damage from sharp edges, nails, staples, splinters
etc.
Unpacking
• Check the air handling unit for visible transport damage.
• Only remove the packaging shortly before assembly.
• Beware of sharp edges during mounting and maintenance. Use protective gloves.
5 Prerequisites for Installation
To ensure a proper and fail-free operation, it is important that the unit is installed according to these instructions.
254496 | v01

Installation | 7
5.1 Location and Space Requirements
The SAVE VTR 250/B should preferably be installed in a separate room (e.g. storeroom, laundry room or similar.).
When choosing the location it should be kept in mind that the unit requires maintenance regularly and that the inspec-
tion door should be easily accessible. Leave free space for opening the door and for taking out the main components
(figure 3.1).
5.2 Wall preparation for mounting bracket
The unit should be installed in such a way that there is no vibration noise
coming from the wall on which the unit is installed.
5.3 Outdoor Air Intake Location Recommendation
Recommended installation location for the outdoor air intake is the northern or eastern side of the building and with a
distance to openings for discharge of stale ventilation air, kitchen ventilator, central vacuum system, waste water drain-
age and other pollution sources like exhaust from traffic, etc. Exhaust air should ideally be led via a roof cowl to the out-
side and with a good distance from the outdoor air intake, windows, etc.
5.4 Access to Power supply
The SAVE VTR 250/B is supplied with approximately 1,5 m cable and plug for 230V, single phase earthed connection.
Make sure a power outlet is reachable by the plug.
6 Installation
Important
• The device may only be installed by qualified, instructed and trained personnel. The persons must know
the relevant safety directives in order to recognise and to avoid risks.
254496 | v01

8| Installation
C — concrete/bricks, W — wood block, G — gypsum, M — mineral wool
X* — adaptable height according to needs.
Make sure the mounting bracket is completely level.
254496 | v01

Electrical connections | 9
Follow the ventilation drawing when connecting the unit to the duct system.
6.1 Ventilation Duct Connection and Insulation
Important
• Always cover the ventilation ducts during construction period.
• Make sure there are no loose objects or impurities inside the ducts.
Install the ducts, supply air diffusers and air intake grilles as shown in the ventilation drawing.
• Supply air and extract air ducts must be insulated if located in cold places.
• Outdoor air and exhaust air ducts with cold air must be insulated if located in warm places (inside building’s vapour
barrier).
It is very important to insulate cold ducts and joints tightly without any gaps, otherwise there is a risk of condensation
which may result in moisture damage.
Do not install the ducts directly against structural building elements to avoid sound propagation. Use acoustic insulation
and sound attenuators.
Note:
The type of ventilation ducts and insulation differ for each building and climate zone. If the ventilation
drawing is not provided, please contact your installer or place of purchase for recommendations.
6.2 Installation and Configuration of Accessories
Please follow instructions included with the accessory or consult “Service and Accessories Installation” manual which
can be found in our online catalogue.
