CAUTION CAUTION
This Air Conditioner has adopted a refrigerant HFC (R32) which
does not destroy the ozone layer.
• As the R32 refrigerant is easily affected by impurities such us
moisture, oxidized film, oil, etc., due to the high pressure, be
careful not to allow the moisture, dirt, existing refrigerant,
refrigerating machine oil, etc., to get mixed up in the refrigeration
cycle during the installation work.
• A special tool for the R32 refrigerant is required for installation.
• Use a new and clean piping materials for the connecting pipe so
that moisture and dirt are not mixed together during the installation
work.
To Disconnect the Appliance from Main Power Supply.
• This appliance must be connected to the main power supply by
means of a switch with a contact separation of at least 3 mm.
 Precautions for using R32 refrigerant
The basic installation work procedures are the same as conventional
refrigerant (R410A, R22) models.
However, Please read through this manual after understanding the
contents below;
These safety cautions describe important matters concerning safety
to prevent injury to users or other people and damages to property.
Please read through this manual after understanding the contents
below (meanings of indications), and be sure to follow the description;
WARNING
• Models that use refrigerant R32 have a different charging port
thread diameter to prevent erroneous charging with refrigerant R22
and for safety.

• Do not use means to accelerate the defrosting process or to clean,
other than those recommended by the manufacturer.
• The appliance shall be stored in a room without continuously
operating ignition sources (for example: open flames, an operating
gas appliance or an operating electric heater.)
• Do not pierce or burn.
• Be aware that refrigerants may not contain an odor.
• The manufacturer may provide other suitable examples or may
provide additional information about the refrigerant odor.
CAUTION CAUTION
When a flammable refrigerant is used, all appliances shall be
charged with refrigerant at the manufacturing location or charged on
site as recommended by the manufacturer.
A part of an appliance that is charged on site, which requires brazing
or welding in the installation shall not be shipped with a flammable
refrigerant charge. Joints made in the installation between parts of
the refrigerating system, with at least one part charged, shall be
made in accordance with the following.
• A brazed, welded, or mechanical connection shall be made before
opening the valves to permit refrigerant to flow between the
refrigerating system parts. A vacuum valve shall be provided to
evacuate the interconnecting pipe and/or any uncharged
refrigerating system part.
• Mechanical connectors used indoors shall comply with ISO 14903.
When mechanical connectors are reused indoors, sealing parts
shall be renewed. When flared joints are reused indoors, the flare
part shall be re-fabricated.
• Refrigerant tubing shall be protected or enclosed to avoid damage.
Flexible refrigerant connectors (such as connecting lines between
the indoor and outdoor unit) that may be displaced during normal
operations shall be protected against mechanical damage.
