F-GAS label
This product contains fluorinated greenhouse gases covered by the Kyoto Protocol
• Chemical Name of Gas
R410A
• Global Warming Potential (GWP) of Gas
1975
CAUTION
1. Stick the enclosed refrigerant label adjacent to the charging and / or recovering location.
2. Clearly write the charged refrigerant quantity on the refrigerant label using indelible ink. Then, place the included
transparent protective sheet over the label to prevent the writing from rubbing off.
3. Prevent emission of the contained fluorinated greenhouse gas. Ensure that the fluorinated greenhouse gas is
never vented to the atmosphere during installation, service or disposal. When any leakage of the contained
fluorinated greenhouse gas is detected, the leak shall be stopped and repaired as soon as possible.
4. Only qualified service personnel are allowed to access and service this product.
5. Any handling of the fluorinated greenhouse gas in this product, such as when moving the product or recharging
the gas, shall comply under (EC) Regulation No. 842/2006 on certain fluorinated greenhouse gases and any
relevant local legislation.
6. Periodical inspections for refrigerant leaks may be required depending on European or local legislation.
7. Contact dealers, installers, etc., for any questions.
Heat insulation for pipe
• Apply the heat insulation to the pipework separately. (liquid, suction and discharge).
• Use thermal heat insulation which can withstand temperatures of 120°C or more.
CAUTION
• Upon completion of the pipework connections fit the piping / wiring panel and the pipe cover.
Gaps between the pipes and the cover are to be filled using a suitable putty or silicone.
• If the pipework is fitted in the downward or sideways position, ensure that the base plate and side plate are closed
and sealed.
• If an opening is left unsealed there is a risk of a fault due to the entering of water or dust.

Electric wiring
WARNING
•
Electrical work must be performed by a qualified electrician in accordance with the installation manual.
•
Ensure the air conditioner uses a designated power supply.
An insufficient power supply capacity or inappropriate installation may cause a fire.
•
When connecting the installation wiring, be sure that all fixing terminal are securely fixed.
•
Ensure earthling practice is correctly performed.
Grounding is necessary, if earthling practice is incomplete an electric shock maybe caused.
CAUTION
•
The installation fuse must be used for the power supply line of this outdoor unit.
•
Incorrect / incomplete wiring might cause an electrical fire or smoke.
•
Prepare the exclusive power supply for the outdoor unit.
•
Ensure an electrical leakage breaker is fitted. This is to prevent the risk of electric shock.
To Disconnect the Appliance from Main Power Supply.
This appliance must be connected to a main power supply by means of a switch with a contact separation of at least 3 mm.
REQUIREMENT
• Perform wiring of the power supply in conformance with the regulations of the local authorities.
• For wiring of the power supply in the indoor unit, refer to the Installation Manual of the relevant indoor unit.
• Never connect 220 V-240 V to the terminal block (U1, U2, U3, U4). (Fault will be caused.)
• Arrange the electrical wiring so that they do not come into contact with high-temperature parts of the pipework;
this is to prevent the risk of insulation melting and causing a possible accident.
• After connecting wires to the terminal block, secure wiring with cable clamp.
• Install control wiring and refrigerant piping within the same line.
• Do not turn on power of the indoor unit until vacuuming of the refrigerant pipe has finished.
• For cabling of the power supply of the indoor units cabling between indoor and outdoor units, refer to the
Installation Manual of the indoor unit.
Connection of power supply wire with control wire
Insert power supply wire and control wire after
removing knockout of the piping / wiring panel at front
side of the outdoor unit.
The knockout piping and the wiring hole are also
provided to the front surface, the right side, and the
rear side.
NOTE
• Be sure to separate the power supply wires and each control wire.
• Arrange the power supply wires and each control wire so that they do not contact with the bottom surface of the
outdoor unit.
• A terminal block (U3, U4 terminal blocks) for connecting an optional part “Central remote controller etc.” is
provided on the inverter unit, so be careful to miswiring.
