SAFETY
Safe and appropriate handling requires knowledge of the basic
safety regulations, and of the intended use of the ventilation
system. Read this manual before operating the ventilation unit.
Please keep the manual for later reference. If you lose the manual,
it can be downloaded from our website.
This user manual contains all the information necessary for safe
operation of the system. All persons who operate and maintain
the ventilation system must follow the instructions provided in this
manual. Furthermore, all local accident prevention regulations must
be observed.
Installation
Installation and setup should only be carried out by a qualified
specialist. Electrical installations and connections must be carried
out only by an electrician and in compliance with local regulations.
WARRANTY
The guarantee and liability exclude damage resulting from:
• Inappropriate use of the ventilation system or the control unit
• Incorrect or inappropriate installation, setup or use
• Neglect of instructions concerning transportation, installation,
use, or maintenance
• Structural or electronic modifications or changes made to the
software
INTENDED USE
All Vallox air handling units have been designed to provide
appropriate and continuous ventilation so as to present no threat to
the health of people and to maintain structures in good condition.
IMPORTANT
In order to ensure that the indoor air presents no harm to
health and remains optimal also for the structures of the
building, ventilation must be kept on without disruptions. It is
recommended that ventilation be left turned on during long
holidays also. This keeps the indoor air fresh and prevents
humidity from condensing in the ventilation ducts and
structures. It also reduces the risk of moisture damage.
WARNING
The unit is not intended
for use by children
under 8 or by persons
with reduced sensory,
physical or mental
capabilities, or whose
lack of knowledge
and experience do not
ensure safe operation
of the unit.
Such persons can
use the unit under
supervision, or
by following the
instructions of someone
who is responsible for
their safety.
Children must be
supervised and not be
allowed to play with the
device.
