U S E R A N D S A F E T Y I N S T R U C T I O N S User and safety instructions Thank you for purchasing this high quality product from inVENTer! This section provides an overview of the basic safety precautions for safe and proper operation of your ventilation unit.
• The volume of supply air should match the volume of extract air. We recommend an external air supply for inVENTer PAX. This may be realised by appropriate overflow measures: an air gap of about 10 mm below the door, unscrew the hinges by 5 mm, use a ventilation grille or similar.

Qualified personnel The inVENTer PAX complies with the applicable technical safety requirements and standards for household and similar electrical appliances. It may only be installed, set up and operated in conjunction with this documentation. Installation, electrical connection and set up of the equip- ment may only be performed by qualified personnel.
Real values may be evaluated based on the airflow-pressure curve. Under certain conditions the inVENTer PAX can be installed over the roof. This must be realised on site.
SYS T E M OV E R V I E W Function The inVENTer PAX ventilation system is equipped with an integral cross-flow heat exchanger. It stores the thermal energy from the indoor air (extract air) inside the main module and uses it to warm up the incoming outdoor air.

(percentage indoor air humidity) should be increased. Operating modes The ventilation unit inVENTer PAX provides four operating modes. Functional scope within the operating modes depends on the outside temperature.The following list provides an overview of the possible operating modes and the ventilation unit’s functionality at different temperatures.
Figure 5: Front view: Infrared remote control for inVENTer PAX The remote control is a handheld electronic unit for controlling the core functions of the inVENTer PAX ventilation unit. It is based on infrared technology and depends on optical connection with the main module.
3 Interior wall side 4 Exterior wall side • The inVENTer PAX ventilation system can be installed over several rooms.If the main module is connected to an duct system, the air flow is reduced. Real values may be evaluated based on the airflow-pressure curve (page 39).
