Important Information - Swegon CASA R3 Smart Installation, Commissioning And Maintenance Instructions

!

Important information

Qualified personnel only
Only qualified personnel should carry out in-
stallation, configuration and commissioning.
Standards and requirements
The pertinent national standards and regula-
tions dealing with installation, configuration
and commissioning must be followed if the
equipment is to operate correctly.
At the www.swegonhomesolutions.com ad-
dress (Toolbox > Find PDF) you will find the
document "Project planning instructions for
ventilation", in which power supply, sound,
airflows and duct system requirements are
presented.
Measurement and electrical work
If you carry out voltage tests, measure the
electrical insulation resistance at various
points or perform other remedial meas-
ures that could damage sensitive electronic
equipment, you must first isolate the ventila-
tion unit from the electrical supply grid.
Surge protection
Swegon recommends that all ventilation units
equipped with Smart automatic control be
equipped with a surge protection device.
Earth fault circuit breaker
It is not certain that an earth fault circuit
breaker will operate faultlessly in combi-
nation with the ventilation unit, since the
unit's regulation and control equipment can
cause leakage currents. Comply with local
electrical safety regulations when you install
electrical equipment.
To open the ventilation unit for service
Always ensure that the ventilation unit's
power supply has been isolated before you
open the inspection door! Wait a few min-
utes before you open the inspection door
on the ventilation unit so that the fans have
time to stop and air heaters, if fitted, have
time to cool down.
NOTE! The manual's original language is Finnish.
Swegon reserves the right to alter specifications.
There are no components inside the electri-
cal equipment cabinet that can be serviced
by the user. Leave the servicing or these
components to service personnel. Do not
restart the ventilation unit before you've
identified the cause of the fault and service
personnel have serviced the ventilation unit.
Drying laundry
A tumbler dryer of extract air type or a dry-
ing cabinet must not be connected to the
system due to the high moisture content in
the air it discharges. However, we recom-
mend the use of a condensing tumbler dryer
without duct connection.
Commissioning
Do not commission the ventilation unit until
all carpentry work that produces large quan-
tities of sanding dust or other impurities has
been completed.
The duct connection spigots of the ventila-
tion unit must be covered by lids while the
unit is being transported, kept in storage
and 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 commis-
sion the ventilation system.
Condensation
The surface temperature of the ventilation
unit can drop down to 12 °C during periods
of frost and depending on the moisture con-
tent of the air surrounding the unit, moisture
may condense on the surface. Consequently,
condensation should be taken into account
when choosing furnishings that are to be
installed in the vicinity of the ventilation unit.
