Important information
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 electrical
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
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
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 freezing pro-
tection works correctly.
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.
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.
