Important information
!
This document is intended for everyone involved in the installation work for or the use of a Swegon CASA venti-
lation unit. Read Instructions for Use before you use the ventilation unit. Save the Instructions for Use for future
use. This document is available in our website.
This appliance can be used by children aged from 8 years and above and persons with reduced physical, sensory
or mental capabilities ar lack of experience and knowledge if they have been given supervision or instruction con-
cerning use of the appliance in a safe way and understand the hazards involved. Children shall not play with the
appliance. Cleaning and user maintenance shall not be made by children without supervision.
Installation and commissioning
Only qualified personnel should carry out installation, con-
figuration 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 produc-
es large quantities of dust or other impurities has been
completed.
The duct connections of the ventilation unit must be cov-
ered 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 electrical insula-
tion resistance at various points or perform other remedial
measures that could damage sensitive electronic equip-
ment, you must first isolate the ventilation unit from the
electrical supply grid.
It is recommended that all CASA ventilation units should
be equipped with a surge protection device and a residual
current circuit breaker. Comply with local electrical safety
regulations.
If the supply cord is damaged, it must be replaced by the
manufacturer or its service agent or a similarly qualified
person in order to avoid a hazard.
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 heater in the ventilation sys-
tem the system should be equipped with damper in out-
door air duct so that the air heater cannot freeze during a
power failure and unit freezing protection works correctly.
Separate extract air
The separate extract air duct runs past the heat
exchanger. The extract air from the kitchen should be
conducted to the ventilation unit's extract air duct.
Note that separate extract air flow affects the ventila-
tion unit's annual efficiency.

Condensation
The surface temperature of the ventilation unit can drop
down to low during periods of extremely low outdoor
temperature and depending on the moisture content of the
air surrounding the unit, moisture may condense 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
To take advantage of the versatile functions of the ventila-
tion unit, use an external duct battery. Especially when the
outside temperature is below -10 ° C.
To open the ventilation unit
Always isolate the ventilation unit's power supply cable
before you open the inspection door! Wait a few minutes
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 malfunction, 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.
Product warranty
The warranty is applicable only when the service of the unit
is performed in accordance with the device manufacturer's
recommendations. The unit must be maintained with original
