can still be heard after stop of running.	The machine stops after running a drain-up mechanism for 3 minutes when air-cooling operation is stopped.

The following symptoms are not air conditioner failures:

•The air blown out from the air conditioner can sometimes give off odors. This is due to cigarette smoke contained in the air of the room, the smell of cosmetics, the walls, furniture, etc., absorbed in the air conditioner.

•A hissing noise can be heard immediately after the air conditioner is started or stopped. This is the sound of the refrigerant flowing inside the air conditioner. The problem is insignificant.

•The air conditioner sometimes snaps or clicks at the beginning or end of cooling/heating operation. This is the sound of friction on the front panel and other sections due to inflation and contraction caused by temperature change. The problem is insignificant.

Range of application

The range of working temperatures for both the indoor and outdoor units of the series Y, R2, Multi-S is as below.

Caution:

The use of your air conditioner outside the range of working temperature and humidity can result in serious failure.

In den folgenden Fällen handelt es sich nicht um eine Störung.

•Die aus der Klimaanlage ausgeblasene Luft kann einen Geruch haben. Der in der Raumluft enthaltene Geruch von Zigaretten, Kosmetika, Wänden, Möbeln usw. haftet in der Klimaanlage an und wird wieder ausgeblasen.

•Bei laufender oder angehaltener Klimaanlage kann das Geräusch von fließendem Kühlmittel zu hören sein. Dies stellt kein Problem dar.

•Nach Start oder Stop von Kühl- oder Heizbetrieb kann sich die Vorderplatte usw. wegen des Temperaturunterschieds hörbar verziehen. Dies stellt kein Problem dar.
