the indoor. Install the units securely so that they do not topple or fall.
• Do not install the unit in the following areas:
• Area with high salt content, such as at the seaside. It will deterio-
rate metal parts, causing the parts to fail or the unit to leak water.
• Area ¿ lled with mineral oil or containing a large amount of splashed
oil or steam, such as a kitchen.
It will deteriorate plastic parts, causing the parts to fail or the unit to
leak water.
• Area that generates substances that adversely affect the equip-
ment, such as sulfuric gas, chlorine gas, acid, or alkali.
