OPERATING AND INSTALLATION INSTRUCTIONS SYSTEM VENTECH LG 150 PAGE 5
The LG 150 System VENTECH range of
compact ventilation units is suitable for
installation in air-conditioning systems
for controlled mechanical ventilation and
deaeration of spaces and dwellings with
purposes similar, for example, to seminar
rooms and small oces at an adjustable
air flow volume of up to 150 m³/h (LG 150
A) or approx. 200 m³/h for up to 160 m²
(LG 150 B with high air capacity).
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 ecient heat recovery system, and
to influence indoor air humidity.
The unit’s scope and designated use
is limited to use in ventilation and air
conditioning systems for the extraction of
used air and the supply of fresh, temper-
ature-controlled outdoor air at maximum
conveyed media temperatures of -15°C
to + 35°C. In addition, the air conveyed
must be free of aggressive vapours and
abrasive material. Any other use shall be
deemed contrary to designated use. The
manufacturer shall accept no responsibil-
ity for damages or consequential damag-
es arising from improper use.
Designated use also includes adherence
to our prescribed operating and installa-
tion 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
an external 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 compact
ventilation unit from the LG 150 System
VENTECH range 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,
installing or working on the
unit must have read and
understood the operating instructions,
in particular Section 4: “Safety”. The end
user must also be instructed on potential
hazards.
