Over and above this operating and instal-
lation manual, local and national regula-
tions and standards shall also apply to the
operation of this unit without limitation.
Take instruction from your installer on
the unit and on its control unit following
installation. The ventilation unit may only
be used subject to the
"Designated use"
section
.
All safety and danger notices attached to
the unit must be observed. In the event
of a malfunction, switch off the unit imme-
diately and secure against accidental
re-activation. Faults must be remedied
immediately. After repairs and mainte-
nance work, qualified personnel must
verify that the unit is safe to operate.
Attachment or installation of additional
parts and components is not permit-
ted. Modifications and alterations to the
LG 250 A compact ventilation unit are
prohibited. Only original spare parts may
be used.
Modifications and alterations to the
ventilation unit are prohibited and absolve
the manufacturer from all warranties and
liability. Ensure that children do not play

SAFETY REGULATIONS
UNIT SET-UP
National and local regulations
must be observed during
installation and setup. The unit
may only be installed in compliance with
national installation regulations.
Installation shall be carried out in ac-
cordance with the general local building,
safety and installation regulations of the
relevant community or the water and
electricity department and other bodies.
The unit may only be installed in frost-free
and dry rooms. The room temperature at
the installation area must consistently
be between a min. of +5 °C and a max. of
+40 °C.
The unit is designed for upright or wall
installation and may only be set up on a
suitable, load-bearing floor. The unit must
not be exposed to vibration of any kind.
Suitable drainage of condensate gener-
ated when operating the unit will be re-
quired, including effective odour blocking
traps (siphon).
Water, heating and condensate connec-
tions may only be installed by a specialist.
The unit must be installed and executed
appropriately so as to ensure seal-tight-
ness and effective condensate drainage in
order to exclude the possibility of building
damage. Effective condensate drainage
must be verified on-site prior to initial
start-up and after servicing the unit. The
maximum permissible load must be ob-
served when transporting the unit.
Components of the ventilation plant, e.g.
air ducts which may need to be installed
in unheated areas, must be suitably insu-
lated to prevent heat loss or condensate
formation (for temperatures under dew-
point). Observe all locally-applicable con-
struction and fire protection guidelines,
regulations and standards. If necessary,
appropriate suitable measures should be
taken when installing the unit e.g. installa-
tion of fire dampers in air ducts, etc.
