OPERATING AND INSTALLATION MANUAL SURFACE-MOUNTED UNIT LG 100 AP
PAGE 10
Changes reserved
Installation shall be carried out in accordance 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 place of installation must be consistently b5 °C min. and +35 °C max. The unit is designed for
upright installation or wall installation and may only be set up on a suitable, load-bearing construction. The unit must not be exposed
to vibration of any kind.
Components of the ventilation unit, e.g. air ducts which may need to be installed in unheated areas, must be suitably insulated to
prevent heat loss or condensate formation (for temperatures under dewpoint). Observe all locally-applicable construction and fire
protection guidelines, regulations and standards. If necessary, appropriate suitable measures should be taken when installing the
unit, e.g. installation of fire dampers in air ducts, etc.
5.3. Setting up the unit
B
The national and local regulations must be heeded when installing and setting up the unit. The unit may only be
installed in compliance with national installation regulations.
B
Any work practices that could potentially impair the safety of the unit are prohibited!
To ensure safe operation, safety devices must not be removed or bypassed.
Electrical equipment and the unit's warning and protective devices must be inspected regularly to ensure that they are in perfect
working order. In the event of faults in the electrical power supply or identification of defects, e.g. loose connections or burnt cables,
the unit must be switched off immediately. Damaged or faulty power supply cables to the unit must be repaired immediately to avoid
hazards. The unit may not be operated until safe operational conditions are restored. Fault finding and immediate remediation of
electrical defects and malfunctions shall be carried out by authorised electricians only. All protective measures must be inspected
(e.g. earth resistance, etc.) after completion of electrical work on the unit.
Warning: hazardous electrical voltage! Ignoring the danger may result in death, injuries or material damage.
Before carrying out any work on live parts, the unit must always be disconnected completely from the power
supply (all poles) and secured against being switched back on.
5.4. Electrical connections
B
Electrical connection work and work on the system's electrical components may be carried out by authorised
electricians only, in compliance with national and local regulations.

Before opening the unit and when carrying out work on the unit e.g. maintenance work and repairs, the unit must
be isolated from the mains (all poles disconnected) and secured against being switched back on for the duration of
the work. The compact ventilation unit must be connected to a 230 V / 50 Hz voltage supply and with correct phase
polarity. The mains supply line must be provided with a strain relief.
To the external interfaces exclusively fittings may be connected for which it is proven that there is an electrically
protective separation between the interface and those active parts of the fitting, which are not operated with safety
extra-low voltage (SELV/PELV), in compliance with DIN EN 61140, e.g. by double or reinforced insulation complying
with DIN EN 60335-1 or DIN EN 60730-1.
