Refrigerant Piping
Piping kit used for the conventional refrigerant cannot be used.
Use copper pipe with 0.8 mm or more thickness for φ9.5mm.
Use copper pipe with 1.0 mm or more thickness for φ15.9mm.
Use copper pipe with 1.0 mm or more thickness for φ19.0mm.
Use copper pipe with 1.0 mm or more thickness for φ22.0mm.
Use copper pipe with 1.0 mm or more thickness for φ25.0mm.
Use copper pipe with 1.0 mm or more thickness for φ28.0mm.
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
