For R32 model, use pipes, flare nut and tools which is specified for R32 refrigerant. Using of existing (R22)
piping, flare nut and tools may cause abnormally high pressure in the refrigerant cycle (piping), and possibly
result in explosion and injury.
•
Thickness of copper pipes used R32 must be more than 0.8mm. Never use copper pipes thinner than 0.8mm.
•
Do not perform flare connection inside a building or dwelling or room, when joining the heat exchanger of
indoor unit with interconnection piping. Refrigerant connection inside a building or dwelling or room must be
made by brazing or welding. Joint connection of indoor unit by flaring method can only be made at outdoor or
at outside of building or dwelling or room. Flare connection may cause gas leak and flammable atmosphere.
•
After completion of installation or service, confi rm there is no leakage of refrigerant gas. It may generate toxic
gas when the refrigerant contacts with fire.

units recommend installation height 2.5 m.).
•
Comply with national gas regulations.
CAUTION
•
Exposure of unit to water or other moisture before installation could result in electric shock. Do not store it
in a wet basement or expose to rain or water.
•
After unpacking the unit, examine it carefully for possible damage.
•
Do not install the unit at place where leakage of flammable gas may occur. In case gas leaks and
accumulates at surrounding of the unit, it may cause of fire.
•
Do not install in a place that can increase the vibration of the unit. Do not install in a place that can amplify
the noise level of the unit or where noise and discharged air might disturb neighbors.

The manufacturer shall not assume any liability for the damage caused by not observing the description of
this manual.
For Reference:
If a heating operation would be continuously performed for a long time under the condition that the outdoor
temperature is 0°C or lower, drainage of defrosted water may be difficult due to freezing of the bottom
plate,
resulting in a trouble of the cabinet or fan.
It is recommended to procure an antifreeze heater locally for a safe installation of the air conditioner.
For details, contact the dealer.
