•Keep ignition sources away (heat, sparks, open flames, hot surfaces).
•Use a damp cloth or sponge to remove condensation water and for cleaning. Do
not use dry clothes or sponges to dry the unit. (Risk of electrostatic charge and
sparking)
•Before starting-up and restarting, fill the drain with approx. 2 litres of water.
Prevents carry-over of refrigerant into drains.
•It is prohibited to cover any ventilation opening of the unit. Safe minimum
distance must be kept (between units) to ensure sufficient air access
•Do not use any mechanical devices or other means (e.g., ice scrapers) to
accelerate the defrosting.
•Do not use steam or high-pressure cleaners for basic cleaning.
•Only install the units in well-ventilated rooms.
•Do not install the units in cellars or lowered rooms.
