4 About this document
This installation manual concerns air handling unit type SAVE VTR 700 manufactured by Systemair UAB.
The manual consists of basic information and recommendations concerning the design, installation, start-up and opera-
tion, to ensure a proper failure-free operation of the unit.
The key to proper and safe operating of the unit is to read this manual thoroughly, use the unit according to given
guidelines and adhere to all safety requirements.
5 Product information
5.1 General
The SAVE VTR 700 is a heat recovery ventilation unit, with a built in rotating heat exchanger. The SAVE VTR 700 is suit-
able for houses with up to 600 m2heated living area.
The SAVE VTR 700 supplies filtered outdoor air to residential areas and extract air from bathroom, kitchen and wet
rooms.
211480 | B003

GB Product information | 7
5.2 Left and Right models
There are two model options, right (R) and left (L) model. The different models are recognized by the placing of the in-
ternal components and the supply air outlet, which is situated on left side of the unit on an (L) unit and on the right hand
side on an (R) unit.
Note:
This document describes a right (R) model. The inside of a left (L) model is mirrored.
5.3 Installation recommendation regarding condensation
5.3.1 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.
5.3.2 Condensation outside of the unit
When the unit is installed in warm humid areas (like laundry) together with low outdoor temperature there is a certain
point where moisture can condense outside of the casing. The condensation relation to indoor relative humidity, 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.
1. Room temperature 20°C
2. Room temperature 22°C
3. Room temperature 24°C
4. Room temperature 26°C
Examples when condensation outside of the unit can occur:
211480 | B003

8| Product information GB
Example A: If the unit is installed in room where temperature 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.
5.4 Transport and storage
The SAVE VTR 700 should be stored and transported in such a way that it is protected against physical damage that can
harm panels etc. It should be covered so dust, rain and snow cannot enter and damage the unit and its components.
The appliance is delivered in one piece containing all necessary components, wrapped in plastic on a pallet for easy
transportation.

5.6 System curves
Every change in the pressure of the ventilation system, will result in a different airflow.
Each curve shows a different airflow level setting:
1. 16% (MINIMUM LEVEL)
2. 20% (LOW LEVEL)
3. 50% (NORMAL LEVEL)
4. 80% (HIGH LEVEL)
5. 100% (MAXIMUM LEVEL)
Airflow level settings can be changed in Service menu.
The pressure is affected by the filter type and differ with each filter combination.

6 Installation
This section describes how to install the unit correctly. To ensure a proper and fail-free operation, it is important that
the unit is installed according to these instructions.
6.1 Unpacking
Verify that all ordered equipment are delivered before starting the installation. Any discrepancies from the ordered
equipment must be reported to the supplier of Systemair products.
6.2 Where/how to install
The SAVE VTR 700 should preferably be installed in a separate room (e.g. storeroom, laundry room or similar.).
When choosing the installation position, consideration must be taken that the unit requires regular maintenance. Leave
free space for opening of the front hatch in order to perform service and maintenance on components inside the unit.
The SAVE VTR 700 is supplied with approximately 2 m of power cable and fitted with a plug for 230V, single phase
earthed connection located at the bottom of the unit.
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. Stale discharge air should ideally be led via a roof unit to
the outside and with a good distance to any outdoor air intake, windows etc.
6.3 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.

GB Installation | 13
6.4 Installing the 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.
Fig. 5 Installation position (right hand unit)
6.4.1 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 installa-
tion 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 ob-
tained from Systemair.
4 Connect the unit to the duct system. Make sure that
all necessary accessories are used to create a func-
tional 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.

er during cold nighttime.
If the temperature is very low and the heater is activated during the nighttime (even with lowered temperature set-
point), then during the upcoming daytime indoor temperature will be increased using the heat exchanger so that accu-
mulated heat could be used during the next cold nighttime, the lowered setpoint for the heater remains.

functions/modes if selected: ECO mode is always activated by the following modes:
•AUTO mode
•MANUAL mode
•AWAY mode
•HOLIDAY mode
•CENTRAL VACUUM CLEANER function
•COOKER HOOD function
