Use copper pipe with 0.8 mm or more thickness for φ9.5.
Use copper pipe with 1.0 mm or more thickness for φ15.9.
Use copper pipe with 1.0 mm or more thickness for φ19.0.
Flare nut and flare works are also different form those of the
conventional refrigerant.take out the flare nut attached to the main
unit of the air conditioner, and use it.
Before installation

Installation Place
A place which provides a specified space around the outdoor unit.
A place were the operation noise and discharged air are not given
to your neighbors.
A place that is not exposed to a strong wind.
A place that does not block a passage.
When the outdoor unit is installed in an elevated position, make

Install the outdoor unit at a place where discharge air is not blocked.
When an outdoor unit is installed in a place that is always exposed
to a strong wind like a coast or on a high storey of a building, secure
a normal fan operation by using a duct or a wind shield.
Supposing the wind direction during the operation season of the
discharge port is set at right angle to the wind direction.
