I MPORTAN T NOTI CES :
• Heat recovery DUPLEXVENT ventilation units are intended for comfort ventilation in a basic environment with
relative humidity up to 90%. Should the appliance be used for other purposes or not operated properly in
compliance with instructions specified in the User’s Manual, the manufacturer has no liability for resulting damage.
• The appliance may only be operated by adults who have made themselves familiar with the User’s Manual.“
• The user must not tamper with or modify any part of the appliance, particularly its electrical wiring!!
• Only professional service technicians with relevant qualifications may perform equipment repairs. Unprofessional
repairs are very risky and may result in a loss of warranty.
• Before opening the door of the appliance for cleaning, filter replacement or general maintenance, always make sure
that it is disconnected from power supply and cannot be re-connected by another person.
• To prevent injury caused by the fan wheel, ductwork at least 2 metres long must always be connected to the fan
discharge side. The ductwork must be fastened in such a way so that it cannot be removed without using tools.
• The appliance may only be installed in areas with temperatures above 15°C with relative humidity 60% at 20°C.
• If the appliance has been out of operation for a long period of time, extra care must be taken during its re-
commissioning.
• The appliance designed for a basic environment may be operated within the temperature range of ventilation air
between -25°C and 45°C and relative air humidity up to 90%, in an environment where there is no risk of fire or an
explosion of flammable gases and fumes containing organic solvents or aggressive substances that might damage
the mechanical parts of the unit. If there is a danger of such gases and fumes temporarily entering the duct (e.g.
floor bonding, painting), the appliance must be switched off sufficiently in advance.
• Electrical installation, commissioning and adjustment of the appliance may only be carried out by persons with
appropriate electrotechnical qualifications.
• Before installing the appliance and putting it into operation, carefully read the User’s Manual!!
• The appliance and all accessories must be installed and used in compliance with the project, the manufacturer’s
technical conditions and applicable legal regulations and technical standards in effect.
• The appliance may not be installed or operated in an aggressive environment that could adversely affect external
and internal mechanical components.
• Before putting the appliance into permanent operation, an initial inspection report of the power supply for the
appliance must be provided.
• In the event of a failure, the appliance must be disconnected from power supply as soon as possible!
• During the handling and installation of the appliance comply with all principles of safe work (including the safety of
work at height and work with suspended loads) and use appropriate work and protective equipment.
• During installation avoid damaging or deforming the appliance’s case.
• An appliance fitted with a hot water air heater (optional accessory) must be permanently connected to power supply
to provide for the anti-freeze protection of the hot water air heater. In case of a prolonged power outage the heating
medium must be drained from the hot water air heater. We recommend draining the heating medium from the
heater by pressurized air instead of gravity flow!!
The manufacturer cannot be held liable for damages resulting from the unprofessional
installation of the appliance in disagreement with the installation manual and common
practices in installing HVAC units and control systems
