Selección del lugar de instalación

Unidad interior

Coloque la unidad sobre una superficie que pueda soportarla correctamente y no
provoque vibraciones.
Asegúrese de que el lugar no se ve afectado por calor o vapor generado en las
cercanías y donde las tomas de entrada y salida no estén obstruidas.
Asegúrese de que el lugar permita un drenaje sencillo y en el que puedan
conectarse los tubos a la unidad exterior.
Asegúrese de que el aire frío pueda distribuirse uniformemente por la sala.
Coloque la unidad interior cerca de una toma de suministro eléctrico con espacio
suficiente alrededor. (Consulte los diagramas).
Coloque la unidad interior de modo que se encuentre a más de 1m de televisiones,
radios, aparatos inalámbricos y lámparas fluorescentes.
En el caso de fijar el control remoto a una pared, colóquelo donde la unidad interior
pueda recibir su señal mientras estén encendidas las lámparas fluorescentes de la
sala.

Unidad exterior

Seleccione el lugar menos afectado por la lluvia o la luz solar directa y
suficientemente ventilado.
Elija un lugar que permita soportar el peso de la unidad y que no amplifique el
ruido y las vibraciones.
Seleccione un lugar en el que los residuos y el viento generado por la unidad no
cause una molestia a los vecinos.
Coloque la unidad en un lugar en el que pueda disponerse de la distancia de
separación marcada
