3.3 Installation recommendation regarding condensation
3.3.1 Condensation inside of the unit
The unit should run continuously. If the unit is intended to be stopped by the user manually or due to calendar function
we recommend to install air tight dampers at extract 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 outdoor ducts during these stop periods. It also might be that cold air from out-
side 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.
333565 | v1.1

6| Delivery, Transport, Storage
3.3.2 Condensation outside of the unit
1. Room temperature 26°C
2. Room temperature 24°C
3. Room temperature 22°C
4. Room temperature 20°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 24°C, outside temperature is –15°C, then dew will
start accumulating when relative humidity is 46% and
higher.
4 Delivery, Transport, Storage
4.1 Transport and storage
The SAVE VTR 700 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.
333565 | v1.1

Installation | 7
5.1 Location and Space Requirements
The SAVE VTR 700 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 4).
5.1.1 Required space
In order to be able to remove filters (figure 4) the unit needs to be installed with sufficient space in front as described
below.
Fig. 4 Space required
A 1580 mm
5.2 Condensation drainage
In general no condensation drainage is needed for rotational heat exchangers at dry conditions. However, if a lot of hu-
mid air is present in the residence, a condensation drainage might be needed. Drainage connection is available as an ac-
cessory and can be ordered separately. Installation instructions for the drainage are enclosed in the drainage pipes
delivery.
Note:
The drainage connection is plugged in the bottom of the unit at delivery. To use the drainage: remove the
rubber seal and connect the drainage pipe. Connect the drainage pipe to the sewer. The water can not be
led straight to the sewer without a water trap.
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 700 is supplied with approximately 2 mcable 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.
333565 | v1.1

8| Installation
Fig. 5 Installation position (right hand unit)
The unit must be installed in the following position (figure 5). It is important
that the unit is completely level in order for the condensation drainage to
work properly.
6.1 Installation procedure
1 Prepare the surface where the unit is to be mounted. Make sure that the
surface is flat, levelled and that it supports the weight of the unit. Perform
the installation in accordance with local rules and regulations.
2 Place the unit standing on the floor. Use the enclosed adjustable feet to
level the unit
Caution
Beware of sharp edges during mounting and maintenance.
Use protective gloves
3 Connect the condensate drainage to the drain plug in the bottom of the
unit. Make sure to use correct drain trap. The height (H) must be at least
60 mm. Drain traps are not included on delivery and can not be obtained
from Systemair.
Note:
Remove caps from the drainage holes inside the unit.
4 Connect the unit to the duct system. Make sure that all necessary acces-
sories are used to create a functional ventilation solution.
Important
The installation of the unit and complete ventilation system
must be performed by an authorized installer and in
accordance with local rules and regulations.
5 Connect the unit electrically to a main outlet using the provided plug and
check that it starts up correctly.
6.2 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).
333565 | v1.1

Electrical connections | 9
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.
6.3 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.
