Safety

Risk to health if filters are not replaced or if there are no air filters.

Heavily soiled or moist air filters can accumulate harmful substances (mould, germs, etc.). This may also happen if the unit is shut down for an extended period. If the air filter is missing, the unit and air ducts become soiled.

  1. Never operate the unit without air filters.
  2. Only use original filters.
  3. Regularly change air filter when a filter change is indicated (LED or TimeStrip).
  4. If the unit has not been used for a long time, always replace the air filters.

Unit damage during conveying of solid particles which may stick to the exhaust air element.

The air filter clogs → Exhaust air element no longer functions.

  1. Do not use the exhaust air element to convey solid particles.

Damage to the unit when conveying greasy air.

The air filter clogs → Exhaust air element no longer functions.

  1. Do not use the exhaust air element for conveying greasy air.

Operation with a soiled air filter is not permitted.

Dirty filters generate higher resistance (pressure) → greater operating noise, higher consumption.

  1. Check the air filter regularly for dirt.
  2. Replace the air filter regularly (every 3 to 6 months), depending on the degree of soiling.
  3. Use only original air filters.
