4.1.3. LIABILITY
Local requirements must be taken into consideration by compliance with corresponding standards, laws and directives. The
decentralised compact ventilation unit LG 100 may only be installed in rooms, flats or utilisation units of a comparable size in which
fireplaces dependent on room air are installed, if:
• simultaneous operation of room air-dependent fireplaces and the air extraction unit is prevented by safety devices, or
• the flue gas evacuation of the room air-dependent fireplace is monitored by special safety devices. In the case of room-air
dependent fireplaces for liquid or gaseous fuels, activation of the safety device must lead to the switch-off of the fireplace or
ventilation unit. In the case of room-air dependent fireplaces for solid fuels, activation of the safety device must lead to the switch-off
of the ventilation unit.
The ventilation units for the controlled aeration and ventilation of a flat or a comparable living unit must not be installed if room air-
dependent fireplaces in the living unit are connected to exhaust gas systems, which themselves have multiple connections. Normal
operation requires the possibility of shutting potentially available combustion air ducts as well as exhaust gas systems off from room
air-dependent fireplaces. In the case of exhaust gas systems of fireplaces for solid fuels, it must be ensured that the shut-off device
can only be operated manually. The position of the shut-off device must be identifiable by the setting of the operating handle. This
specification is considered as complied with if a shut-off device against soot is used. With regard to the fire protection installation
regulations for the set-up of the ventilation unit, the provisions of national law, in particular the building regulation concerning the
fire protection requirements with regard to ventilation systems in the relevant latest version must be observed.
Due to the heavy load as well as the irregular operation, the extract air of an existing kitchen extractor hood must not be integrated
into the dwelling's ventilation system. Extract air from such extractor hoods must be conducted separately by means of an exhaust
air pipe over the roof. The supply air must be provided for separately (e.g. by window ventilation).
If an extractor hood without the separate provision of supply air is operated, the balance of the air volume in the dwelling is no longer
kept and the proper function of the dwelling's ventilation system is no longer ensured (odour diversion, etc.). Another option is to
operate the extractor hood in recirculation mode.
The compact ventilation unit LG 100 has been developed and manufactured for controlled mechanical ventilation and deaeration of
spaces with purposes similar, for example, to seminar rooms and small offices. Proper use requires that combustion air lines and
exhaust systems have the facility to be shut off from fireplaces dependent on ambient air.
Any other use than that described in Section 4 shall be deemed improper and may cause personal injury or damage to the ventilation
unit, for which the manufacturer shall accept no liability.
The manufacturer accepts no responsibility for any damage due to:
• non-compliance with the safety, operating and servicing instructions given in this operating and installation manual.
• the installation of spare parts that have not been supplied by the manufacturer, the responsibility for the use of such spare parts
being fully borne by the system builder/installer.
• Normal wear and tear.
4.1.4. WARRANTY
The warranty period shall commence after the unit is put into operation, but no later than one month after delivery. Warranty
details can be found in our “General terms and conditions” in their latest version as well as the merchant conditions of your
respective country. The warranty shall be subject to proof of services performed as per our instructions and executed by a licensed
installer/specialised company. Warranty claims shall be limited to material and/or constructional defects occurring during the
warranty period. In the event of a warranty claim, the compact ventilation unit LG 100 must not be dismantled without prior written
authorisation from the manufacturer. The manufacturer's liability shall be limited to spare parts installed by an installation company
approved by the manufacturer. The warranty shall automatically lapse at the end of the warranty period, following improper operation
such as operation without a filter, if parts other than original manufacturer-supplied parts are installed, or if unauthorised changes
are made to the unit. Furthermore, the warranty is automatically rendered void by failure to comply with the information in this
operating and installation manual.
