When connecting the air lines, ensure
air-tightness and a suitable vibrational
decoupling. The air lines and attach-
ments, such as sound absorbers etc.,
must only be fixed to the ventilation unit
using adequately dimensioned fixing
elements and to suitable, solid walls or
ceiling elements of the building.
The use of flexible hoses for
making the unit connections
has to be avoided.
When making the line connections it has
to be ensured in particular that no tools
and no installation materials fall into the
unit connections or onto the unit itself.
Damage could then occur to the compo-
nents, for example, to the fans blades.
Suitable and sufficient insulation of the
air line components and installation
components has to be made in ac-
cordance with the project specifications.

Warning: hazardous electrical
voltage!
•
Disregarding the hazard may
result in death, injury or mate-
rial damage.
•
Before carrying out any work on live
parts, the unit must always be dis-
connected completely from the power
supply (all poles) and secured against
being switched back on!
Electrical connection and work on electri-
cal components may only be carried out
by authorised electricians only.
The relevant national and local regula-
tions and standards must be complied
with during assembly and electrical
installation.
Final responsibility for the electrical
installation, cabling, etc. lies with the
electrical contractor which performed
them.
The
LG 500 P System VENTECH
compact
ventilation unit is designed for a
230 V/50
Hz
power supply.
•
The electrical connection must accord
with the electrical switching plan!
•
The cable cross-sections indicated are
minimum cross-sections for copper
lines and do not take cable length or site
conditions into account.
•
Cable type, cable cross-section and lay-
ing must be determined by an author-
ised electrician!
•
Low-voltage cables must be laid sepa-
rately from mains cables; alternatively,
screened cables must be used!
•
The inlet fuse on the power supply line
must be an isolation type!
•
Only pulse or AC/DC sensitive residual
current protective devices (type A or B)
are permitted.
•
Potential equalisation must be put in
place between the unit and the air duct
system!
•
All safety measures must be tested
following electrical connection! (Earth
resistance etc.)
The safety directions in
point 3.2 and in particular
in point 3.2.3. Electrical
con-nection work have to
be complied with for all electrical
work.
