Fluorescent lights
. When installing a wireless user interface in a room with
fluorescent lights, mind the following to avoid interference:
-
Install the wireless user interface as close as possible to the indoor unit.
-
Install the indoor unit as far as possible from the fluorescent lights.
It is NOT recommended to install the unit in the following places because it may
shorten the life of the unit:
▪

In places where a mineral oil mist, spray or vapour may be present in the
atmosphere. Plastic parts may deteriorate and fall off or cause water leakage.
▪
In places where the unit would be in the path of direct sunlight.
▪
In bathrooms.
▪
Sound sensitive areas (e.g. near a bedroom), so that the operation noise will
cause no trouble.

Otherwise condensation on the unit or refrigerant pipes, air filter dirt or drain
blockage may cause dripping, and objects under the unit may get dirty or damaged.
