[. . . ] When the outdoor unit is to be installed in an elevated position, be sure to secure its feet. An allowable length of the connecting pipe is up 15 m. An allowable height level is up to 10 m. A place where the drain water does not raise any problem. 9-3-2. Refrigerant piping connection <Flaring> 1. Cut the pipe with a pipe cutter. Obliquity Roughness Warp 90 Fig. Insert a flare nut into the pipe, and flare the pipe. Projection margin in flaring : A (Unit : mm) A Die Pipe Fig. Install the outdoor unit without anything blocking the air discharging. 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 place where high-frequency waves are likely to be generated as from audio equipment, welders, and medical equipment.
