CAUTION
Arrange the drain pipe for proper drainage from the unit.
Improper drainage can result in dew-dropping.
This air conditioner has the structure designed
to drain water collected from dew, which forms
on the back of the indoor unit, to the drain pan.
Therefore, do not store the power cord and other
parts at a height above the drain guide.
CAUTION
1. Install the outdoor unit without anything blocking the air discharging.
2. When the outdoor unit is installed in a place always exposed to strong
wind like a coast or on a high storey of a building, secure the normal fan
operation using a duct or a windshield.
3. In particularly windy areas, install the unit such as to avoid admission of
wind.
4. Installation in the following places may result in trouble.
Do not install the unit in such places.
• A place full of machine oil
• A saline-place such as the coast
• A place full of sulfi de gas
• A place where high-frequency
waves are likely to be generated
as from audio equipment, welders,
and medical equipment
