Proper use
Operation of the unit
The unit may only be operated if it has been installed correctly and according to the
specifications and directives of the installation manual of the unit.
The unit may be operated by the following groups of people: children from age 8,
persons with limited physical, sensory or mental abilities, or persons with insufficient
experience and specialised knowledge, provided they are supervised or instructed in
the safe handling of the unit and understand the associated hazards.
Children must not play with the unit.
Children must not carry out cleaning and maintenance without supervision.
Intended use
The FOCUS unit can be used for controlled ventilation in homes and offices (and
also in industrial buildings subject to certain restrictions). Any other use or any use
beyond this is considered improper use.
The ventilation unit is not suitable for smoke extraction or drying buildings, for
ventilation of rooms with aggressive and corrosive gases or for rooms with extreme
dust levels.
The unit must not be used for extracting combustible or explosive gases.
Intended use also includes observing all instructions in the instruction manual.
In the event of improper use, the Zehnder Group accepts no liability for any damage that may occur and no warranty
for the proper and functional operation of the ventilation unit.
Provisions for operation with fireplaces
Local requirements must be taken into account through appropriate standards, laws and guidelines. The FOCUS unit
may only be installed in rooms, apartments or utilisation units of comparable size in which open flue fireplaces are
installed if:
•
safety features prevent simultaneous operation of open flue fireplaces and the air extracting system or
•
the flue gas discharge of the open flue fireplace is monitored by special safety features. In case of open flue
fireplaces for liquid or gaseous fuels, the fireplace or the ventilation system must be switched off if the safety
feature is triggered. In case of open flue fireplaces for solid fuels, the ventilation system must be switched off if the
safety feature is triggered.
The ventilation units for controlled ventilation of an apartment or comparable utilisation unit must not be installed if
open flue fireplaces are connected to multiple-occupancy flue systems in the utilisation unit.
For proper operation, it must be possible to shut off any combustion ventilation lines and flue gas systems of open
flue fireplaces. In case of flue gas systems of fireplaces for solid fuels, it must only be possible to operate the cut-off
device manually. The position of the cut-off device must be recognisable from the setting of the operating handle.
This is considered to be fulfilled if a cut-off device against soot (soot blocker) is used. Fire protection requirements
with regard to the fire protection installation regulations for the construction of the ventilation system, and federal
state regulations, in particular the building authority guideline on the fire protection requirements for ventilation
systems in the currently valid version, must be observed.
