Ventilation units

INTRODUCTION
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.
Retain 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 be carried out only by qualified
experts. Electrical installations and connections must be carried
out only by an electrician and in compliance with local regulations.
GUARANTEE
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
NOTE
For further information,

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.
INTENDED USE
All Vallox ventilation units have been designed to provide
appropriate and continuous ventilation so as to present no threat to
health 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.
DISPOSAL OF THE VENTILATION UNIT
Do not dispose of electronic devices with household waste. Follow
local laws and regulations on safe and ecological disposal of the
product.

INSTALLATION
GENERAL INSTALLATION INSTRUCTIONS
INSTALLATION SITE
The Vallox ventilation unit must be installed in a
location where the temperature remains above
+10°C. When the unit is installed without a protective
enclosure, the location must be chosen so that its
noise does not cause any disturbance (e.g. storage
premises, technical spaces, and false ceilings).
CONDENSING WATER
The unit is delivered with a water seal that has an air
lock and a more compact elbow. When the elbow is
used, an air lock must be installed somewhere else
between the extraction pipes (the parts needed are
included in the accessory bag). The air lock ensures
the removal of condensing water and mues any
noise.
WARNING
Water must at all times be kept
out of the electrical system.
50

INSTALLATION SITE
Vallox TSK Multi 50 MV and Vallox TSK Multi 80 MV
must be mounted on the ceiling. Use the mounting
hooks (4 pcs) delivered with the unit to mount the
ventilation unit on the ceiling. Observe the weight of
the unit (45 kg / 58.5 kg) when mounting.
IMPORTANT
The unit must be installed straight so that the
condensing water that collects in the bottom pool
drains through the condensing water outlet.
NOTE
Reserve a space equal to the depth of the unit in front
of the unit for servicing purposes.
INSTALLATION
NOTE
The whole length of the outdoor air duct to the unit
and exhaust air duct from the unit must be insulated
using closed cell insulation.
MEASURING TUBES
The accessories delivered with the unit include four
air flow measuring tubes. These can be inserted in the
ducts to allow for easier ventilation adjustment.
