The compact ventilation unit is not a ready-to-use product. It must not be put into operation until it has been properly installed and
connected. Only qualified and instructed personnel may carry out connection and service work on the unit.
B
In order to prevent an uncontrolled formation of condensate in the unit, continuous operation with an extract air
humidity of more than 60 % has to be avoided at outdoor temperatures below 0°C (e.g. private spa area).
B
Persons transporting, installing or working on the unit must have read and understood the operating instructions, in
particular Section 5 "Safety". The end user must also be instructed on potential hazards.
With the ventilation unit LG 100 you can provide a maximum degree of flexibility to your ventilation concept. The used air is extracted
from the living areas, and fresh, filtered outdoor air is supplied again. In this process, the high-quality enthalpy exchanger allows for
ecient heat and moisture recovery and ensures a well-balanced room humidity and a pleasant room climate.
Highly ecient and low noise EC radial fans allow for extremely energy-saving and low-noise operation. In the switched-o state,
the outdoor and exhaust air openings are automatically closed mechanically. The integrated sensors record the VOC and eCO2
concentration of the extract air and, in automatic mode, allow for an operation depending on the room air quality.
The decentralised compact ventilation unit LG 100 is operated easily and intuitively by means of a pushbutton directly on the unit or
via the PICHLER APP. Therefore the unit comes with a WLAN connection as a standard feature. Optionally you can additionally connect
an external control unit via cable connection.
The compact ventilation unit LG 100 is intended for the installation into ventilation and air conditioning systems for the controlled
domestic ventilation in small and medium-sized residential units (approx. 80m²). The purpose of controlled mechanical ventilation
and deaeration of domestic areas is to improve air quality and reduce the heating energy demand through the use of a highly
ecient heat recovery system, and to impact on indoor air humidity. The scope and intended use for the unit are limited to the use
in residential and recreation spaces for the extraction of used air and the supply of fresh, tempered outdoor air at maximum flow
media temperatures of -15 °C to +35 °C. Furthermore, the air conveyed must be free from aggressive vapours and substances
enhancing wear. Any other use shall be deemed contrary to designated use. The manufacturer shall accept no responsibility for
damages or consequential damages arising from improper use. Designated use also includes adherence to our prescribed operating
and installation manual. This unit is not available to the general public and is intended for the installation in residential or industrial
buildings. The unit is used for mechanical aeration and ventilation of indoor air and, when combined with a heater battery, is also
used to preheat air.
This unit can be used by children from an age of 8 years and furthermore by persons with reduced physical, sensory or mental
capabilities or a lack of experience or knowledge, if they are supervised or if they have been instructed on how to use the unit safely
and if they understand the hazards resulting therefrom. Children must not play with the unit. Cleaning and user maintenance must
not be carried out by children without supervision. The unit is not suitable for outdoor installation and may be installed in suitable and
frost-free interior areas only. The ventilation unit is not suitable for drying new buildings.

4.1.1. STIPULATIONS FOR OPERATION WITH FIREPLACES
4.1.2. STIPULATIONS FOR OPERATION WITH EXTRACTOR HOODS
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-o 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-o
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 o from room
air-dependent fireplaces. In the case of exhaust gas systems of fireplaces for solid fuels, it must be ensured that the shut-o device
can only be operated manually. The position of the shut-o device must be identifiable by the setting of the operating handle. This
specification is considered as complied with if a shut-o 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 oces. Proper use requires that combustion air lines and
exhaust systems have the facility to be shut o 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.
