General safety instructions

• Use the ventilation unit only as intended → above-mentioned instructions.
• Have the ventilation unit installed, adjusted, commissioned, cleaned, maintained or repaired by qualified personnel only → Qualified personnel can carry out this work safely, recognise dangers and avoid them.
• Personal protective equipment: Use personal protective equipment (protective clothing, hard hat, protective goggles, etc.) for your own protection in the event of possible hazards. Pay attention to the applicable safety and accident prevention regulations.
• Safety devices are designed for your safety. Never bypass or tamper with the safety devices.

DANGER

• Do not deposit combustible materials, liquids or gases near the ventilation unit → In case of ignition or fire, hazardous substances may enter the rooms through the ventilation system.
• Ventilation units must not be installed if there are air-ventilated fireplaces in the housing unit that are connected to exhaust gas systems, which themselves have multiple connections. → Danger to life due to transfer of waste gases (carbon monoxide) to other residential units.
• Never operate the ventilation unit in an explosive atmosphere or in combination with a lab extraction unit → Risk of explosion due to explosive gases and dusts.
• In the case of subsequent additions or modifications (range hood, air-ventilated fireplace, etc.), have the system compatibility of the ventilation system determined/ensured by a planning office → Risk of injury and risk to health in the event of improper operation. If using an exhaust air range hood or air-ventilated fireplace, this must be accepted by a regional master chimney sweep.
• Risk of suffocation when handling packaging materials. Keep foil materials and small parts away from children.

WARNING

• Install the ventilation unit only in accordance with the planning specifications → Improper operation with incorrect or improperly installed ventilation unit.
• Note the insulation of the ventilation channels.

• Note the sound absorption. Use tubular sound absorbers to reduce noise emissions or for acoustic insulation. Recommendation: Insulate the channels sufficiently to prevent diffusion.

• Never use the ventilation unit to convey chemicals or aggressive gases/vapours → Risk to health if these substances are spread throughout the rooms.
• Before removing the front cover and installing the electrics, switch off all supply circuits and secure them against being accidentally switched back on. Position a visible warning sign.

NOTICE

• Never operate the ventilation unit during the construction phase → Damage to unit caused by contamination of the ventilation unit and ducts.
• Never use the ventilation unit with range hoods with exhaust air mode on → Grease and oil vapours contaminate the ventilation unit and ventilation ducts and can reduce efficiency. In exhaust air rooms with greasy air (kitchens) only use ventilation valves with grease filters. In terms of energy consumption, use range hoods in circulating air mode.
• Never operate a ventilation unit with an enthalpy heat exchanger for long periods at an air humidity > 70 %, for example in swimming pools or to dry out new buildings (permissible for a short period of time, with up to approx. 80 % r.h.). For ventilation units without a condensate drain, damage to the unit or the environment if excessive condensate cannot be removed.
• Do not use any components in the exhaust duct that influence temperature, humidity or air volume, for example a drying cabinet → Possible damage to the unit if metal parts inside the ventilation unit corrode.
• Electrical defect of the ventilation unit when liquid enters the unit openings. → Protect the unit from external moisture during installation, maintenance, cleaning and dismantling. Insulate ducts sufficiently to prevent diffusion.
