The LG 250 A compact ventilation unit is
suitable for installation in air conditioning
systems for controlled mechanical venti-
lation and deaeration of spaces and dwell-
ings with purposes similar, for example,
to seminar rooms and small offices at an
adjustable air flow volume of up to
250 m³/h.
Installation of a mechanical, controlled
domestic ventilation system provides
supply air and exhaust air ventilation for
the entire living area. Controlled air supply
with purified and filtered outdoor air is
provided in supply air areas. Odours and
damp ambient extract air are conducted
away in the extract air area.
The purpose of controlled mechanical
ventilation and deaeration of domestic
areas is to improve air quality, reduce
heating energy demand through use of a
highly efficient heat recovery system, and
to influence indoor air humidity.
The field of application and intended use
of the unit are restricted to use in air
conditioning systems for the extraction of
used air and the supply of fresh, temper-
ature-controlled outdoor air at maximum
temperatures between -15 °C and +35 °C.
In addition, the air supply must be free
from aggressive vapours and substances
which are conducive to wear.
Any other use shall be deemed contrary
to designated use. The manufacturer shall
accept no responsibility for damages or
consequential damages arising from im-
proper use. Designated use also includes
adherence to our prescribed operating
and installation manual.
This unit is available to the general public
and is intended for installation in residen-
tial or industrial buildings. The unit is used
for mechanical aeration and ventilation of
ambient air and, when combined with a
heater battery, is also used to reheat air.
This unit is not intended for use by
persons, including children, with limited
physical, sensory or mental capacities
or lacking experience and/or knowledge,
unless under supervision or instruction of
a person responsible for their safety.
The unit is not suitable for outdoor instal-
lation and may be installed in suitable
and temperature-controlled interior areas
only. The ventilation unit is not suitable for
drying new buildings. The LG 250 A com-
pact ventilation unit is not a ready-to-use
product. It must not be put into operation
until it has been properly installed and
connected to the ventilation system. Only
qualified and instructed personnel may
work on and with the unit.
Personnel transporting, install-
ing or working on the unit must
have read and understood the
operating instructions, in particular
Sec-
tion 4: "Safety"
. The end user must also be
instructed on potential hazards.
