[. . . ] When the outdoor unit is installed in a place exposed 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 wind shield. In particularly windy areas, install the unit such as to avoid admission of wind. Installation in the following places may result in trouble. · A saline-place such as the coast. · A place where high-frequency waves are likely to be generated as from audio equipment, welders, and medical equipment. Drain hose Inside the room Extension drain hose Fig. 8-4-23 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. Wall Drain guide Strong wind Space for pipes Fig. Cut the pipe with a pipe cutter.
