Non-intended use

The ventilation unit must not be used in the following situations under any circumstances.

Read all the safety instructions.

Risk of combustion/fire from flammable materials, liquids or gases in the vicinity of the unit.

  1. Do not place any flammable materials, liquids or gases near the unit, which may ignite in the event of heat or sparks and catch fire.

Risk of death if an air-ventilated fireplace is connected to an exhaust gas system, which itself has multiple connections.

The air-ventilated fireplace may result in exhaust fumes being transferred to other living units. Risk of death, for example from carbon monoxide.

  1. Never use the ventilation unit if there are air-ventilated fireplaces in the housing unit that are connected to exhaust gas systems, which themselves have multiple connections.

Explosion hazard due to gases and dust.

Explosive gases and dust may ignite and cause serious explosions or fire.

  1. Never use unit in an explosive atmosphere (risk of explosion).

Explosion hazard due to explosive substances in the lab extraction units.

Explosive substances in lab extraction units may ignite and cause serious explosions or fire.

  1. Aggressive substances may damage the unit. Never use unit in combination with a lab extraction unit.

Risk to health from chemicals or aggressive gases/vapours.

Chemicals or aggressive gases/vapours may harm health, especially if they are distributed throughout the rooms by the unit.

  1. Never use unit to distribute chemicals or aggressive gases/vapours.

Unit damage during the construction phase, caused by soiling of the unit and air ducts.

Unit operation is not permitted during the construction phase.

  1. Do not operate unit during the construction phase.

Damage to unit due to grease and oil vapours from range hoods.

Grease and oil vapours from range hoods may contaminate the unit and air ducts and reduce efficiency.

  1. Never use unit in combination with range hoods, that are connected directly to the controlled domestic ventilation exhaust duct.
  2. In rooms with greasy exhaust air, e.g. kitchens, only use ventilation valves with a grease filter.
  3. Recommendation: In terms of energy consumption, use range hoods in circulating air mode.

Corrosion of metal parts inside the ventilation unit by additional components in the exhaust duct.

  1. Do not use components which affect temperature, humidity or air volumes on the exhaust duct, for example if a drying cabinet is connected to the exhaust duct.
