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.

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 275/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.

281769 | v01

6| Prerequisites for Installation

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.

5.1 Location and Space Requirements

The SAVE VTR 275/B should preferably be installed in a separate room (e.g. storeroom, laundry room or similar.).

Fig. 4

The SAVE VTR 275/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 in-

spection door should be easily accessible. Leave free

space for opening the door and for taking out the main

components (figure 4).
