Installation recommendation regarding condensation

4.3.1

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.
4.3.2

Condensation outside of the unit

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.
5 Delivery, Transport, Storage
5.1

Transport and storage

The SAVE VSR 300/500 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.
5.2

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.
