2.
Do not use unspecified cord, modified cord, joint cord or extension cord for power supply cord. Do not share the single outlet with
other electrical appliances. Poor contact, poor insulation or over current will cause electrical shock or fire.
other electrical appliances. Poor contact, poor insulation or over current will cause electrical shock or fire.
3. Do not tie up the power supply cord into a bundle by band. Abnormal temperature rise on power supply cord may happen.
4. Do not insert your fingers or other objects into the unit, high speed rotating fan may cause injury.
5. Do not sit or step on the unit, you may fall down accidentally.
6. Keep plastic bag (packaging material) away from small children, it may cling to nose and mouth and prevent breathing.
7.
When installing or relocating air conditioner, do not let any substance other than the specified refrigerant, eg. air etc mix into
refrigeration cycle (piping). Mixing of air etc. will cause abnormal high pressure in refrigeration cycle and result in explosion, injury etc.

8. Do not add or replace refrigerant other than specified type. It may cause product damage, burst and injury etc.
9.
• For R410A model, use piping, flare nut and tools which is specified for R410A 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 or copper pipes used with R410A must be more than 0.8 mm. Never use copper pipes thinner than 0.8 mm.
• It is desirable that the amount of residual oil less than 40 mg/10 m.

Do not use joint cable for indoor / outdoor connection cable. Use the specified indoor/outdoor connection cable, refer to installation
instruction CONNECT THE CABLE TO THE INDOOR UNIT and connect tightly for indoor/outdoor connection. Clamp the cable so that no
external force will have impact on the terminal. If connection or fixing is not perfect, it will cause heat up or fire at the connection.

18.
During installation, install the refrigerant piping properly before running the compressor. Operation of compressor without fixing refrigeration
piping and valves at opened position will cause suck-in of air, abnormal high pressure in refrigeration cycle and result in explosion, injury etc.
