Refrigerant Piping
Piping kit used for the conventional refrigerant cannot be used.
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
Be careful to the following items before installation.
Air purge
For air purge, use a vacuum pump.
Do not use refrigerant charged in the outdoor unit for air purge.
(The refrigerant for air purge is not contained in the outdoor unit.)
Electrical cabling
Be sure to fix the power cables and indoor/outdoor connecting
cables with clamps so that they do not contact with the cabinet, etc.
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
sure it's four feet securely installed.
There must be sufficient space for carrying in the unit.
A place where the drain water does not make any problem.

When installing the outdoor unit in a place that is constantly
exposed to a strong wind such as the upper stairs or rooftop of a
building, apply the windproof measures referring to the following
examples.
Install the unit so that its discharge port faces to the wall of the
building. Keep a distance of 2000mm or more between the unit
and the wall surface.
CAUTION
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.
