5 Product information
5.1 General
The SAVE VSR 300/500 is a heat recovery ventilation unit, with a built in rotary heat exchanger. The SAVE VSR 300/
500 is suitable for houses with up to 240/360 m
The SAVE VSR 300/500 supplies filtered outdoor air to residential areas and extract air from bathroom, kitchen and wet
rooms.

5.2 Installation recommendation regarding condensation
5.2.1 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 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 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 disconnected and closed due to above mentioned effects until commissioning and regular operation.
5.2.2 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.
3
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:
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.
5.3 Transport and storage
The SAVE VSR 300/500 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.

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 VSR 300/500 should preferably be installed in a separate room (e.g. storeroom, laundry room or similar.), but
can also be installed in the loft space.
When choosing the installation position, consideration must be taken that the unit requires regular maintenance. Flooring boards must be mounted up to and under the unit. Light and mains supply should be installed. Leave free space for
removing of inspection doors and for taking out main components inside the unit.
The SAVE VSR 300/500 are supplied with approximately 1 m cable and plug for 230V, single phase earthed connection.
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, waist water drainage 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.
Note:
If the passage to the installation location is narrow, remove the side covers and the side cover support
brackets.
6.3 Installation procedure
A. Upright installation on the floor. Left and right connections are possible.
The enclosed self adhesive vibration dampers must be used.
B. Ceiling installation. Left and right connections are possible.
A ceiling mounting kit is required. Not delivered with the unit. Needs to be ordered separately.

C. Upside down installation is NOT allowed.
1. Make sure that the surface is flat and horizontal and that it supports the weight of the unit. Perform the installation in
accordance with local rules and regulations.
2. Fit the enclosed self adhesive vibration dampers on the unit.
Mount according to the enclosed Vibration Damper Quick Guide.
3. Lift the unit in place
Warning
Beware of sharp edges during mounting and maintenance. Use protective gloves.
Consider the unit weight when mounting!
7
4. Connect the unit to the duct system. Make sure that all necessary accessories are used to create a functional ventilation solution.
Warning
The installation of the unit and complete ventilation system must be performed by an authorized installer
and in accordance with local rules and regulations.
Note:
The unit may not be installed with the electrical connection box facing downward due to the fact that the
heat from the re-heater is rising in the unit!
6.4 Condensation drainage
In general no condensation drainage is needed for rotational heat exchangers at dry conditions. However, if a lot of humid air is present in the residence, a condensation drainage might be needed. Drainage connection is available as an accessory and can be ordered separately.
Note:
The drainage connection is plugged in the bottom of the unit at delivery. To use the drainage: elevate the
unit from the floor, remove the rubber seal and connect the water hose. Connect the water hose to the
sewer. The water can not be led straight to the sewer without a water trap.
7 Electrical connections
The SAVE VSR 300/500 is wired internally from factory.
The electrical connection box is on top of the unit behind a cover plate.
