Important information
This document is intended for everyone involved in the installation work for or the use of a Swegon CASA ven-
tilation unit. Read this Instructions for Use before you use the ventilation unit. Save the Instructions for Use for
future use. This document is available in our website.
The ventilation unit is not designed to be used by children (below 8 years old) or by persons whose senses, physi-
cal or mental capacity or a lack of knowledge and experience limits safe use of the ventilation unit. Such persons
may use the ventilation unit if supervised by a person who is responsible for their safety, or according to the
instructions.
Installation and commissioning
Only qualified personnel should carry out installation,
configuration and commissioning. Only a qualified
electrician is allowed to make electrical installations in
accordance with national regulations.
The national standards and regulations dealing with
unit installation, configuration and commissioning
must be followed.
Do not use the ventilation unit until all work that
produces large quantities of dust or other impurities
has been completed.
The duct connections of the ventilation unit must be
covered by lids until it is mounted at its final location.
Make sure that the ventilation unit, filters and ducts
are clean and that there are no loose objects in them
before you commission the ventilation system.
Electrical work and connections
If you carry out voltage tests, measure the electri-
cal insulation resistance at various points or perform
other remedial measures that could damage sensitive
electronic equipment, you must first isolate the venti-
lation unit from the electrical supply grid.
It is recommended that all Smart ventilation units
should be equipped with a surge protection device.
It is recommended that all Smart ventilation units
should be equipped with a residual current circuit
breaker. Comply with local electrical safety regula-
tions when you install electrical equipment.
Drying laundry
A tumbler dryer of extract air type or a drying cabinet
must not be connected to the system due to the high
moisture content in the air it discharges.
Models with water-based air heater
When there is a water-based post heater in the ven-
tilation system the system should be equipped with
damper in outdoor air duct so that the air heater
cannot freeze during a power failure and unit freez-
ing protection works correctly.
Condensation
The surface temperature of the ventilation unit can
drop down to 12 °C during periods of low outdoor
temperature and depending on the moisture content
of the air surrounding the unit, moisture may con-
dense on the surface. Condensation should be taken
into account when choosing furnishings that are to
be installed in the vicinity of the ventilation unit.
Balancing functions
It is recommended to use external preheater when
balancing functions are used at temperatures below
-10 °C.
To open the ventilation unit for service
Always isolate the ventilation unit's power supply cable
before you open the inspection door! Wait a few min-
utes before you open the inspection door so that the
fans are stopped and electrical heaters are cooled.
There are no components inside the electrical box
that can be serviced by the user. In case of malfunc-
tion, do not restart the ventilation unit before the cause
of the fault is identified and fixed.
Filters
The ventilation unit must not be operated without
filters! Use only original Swegon filters. Find the cor-
rect filter in the section "Technical data".
Warranty conditions
Warranty conditions are included in delivery of the
unit as a separate document.
