Gas leak check
Check with a leak detector or soap water whether gas leaks
or not, from the pipe connecting section or cap of the valve.
REQUIREMENT
Use a leak detector manufactured exclusively for HFC
refrigerant (R410A, R134a, etc.).
Heat insulation process
Apply heat insulation for the pipes separately at liquid side
and gas side.
• For the heat insulation to the pipes at gas side, use the
material with heat-resisting temperature 120 °C or higher.
• To use the attached heat insulation pipe, apply the heat
insulation to the pipe connecting section of the indoor unit
securely without gap.
REQUIREMENT
• Apply the heat insulation to the pipe connecting section
of the indoor unit securely up to the root without exposure
of the pipe. (The pipe exposed to the outside causes
water leak.)
• Wrap heat insulator with its slits facing up (ceiling side).

Electrical connection
WARNING
1. Using the specified wires, ensure to connect the wires, and fix wires securely so that the external tension to the
wires do not affect the connecting part of the terminals.
Incomplete connection or fixation may cause a fire, etc.
2. Be sure to connect earth wire. (grounding work)
Incomplete grounding cause an electric shock.
Do not connect ground wires to gas pipes, water pipes, lightning rods or ground wires for telephone wires.
3. Appliance shall be installed in accordance with national wiring regulations.
Capacity shortage of power circuit or incomplete installation may cause an electric shock or a fire.
CAUTION
• This indoor unit has no power cord.
• If incorrect/incomplete wiring is carried out, it will cause an electrical fire or smoke.
• Be sure to install an earth leakage breaker that is not tripped by shock waves.
If an earth leakage breaker is not installed, an electric shock may be caused.
• Be sure to use the cord clamps attached to the product.
• Do not damage or scratch the conductive core and inner insulator of power and interconnecting wires when peeling them.
• Use the power cord and Interconnecting wire of specified thickness, type, and protective devices required.
REQUIREMENT
• For power supply wiring, strictly conform to the Local Regulation in each country.
• For wiring of power supply of the outdoor units, follow the Installation Manual of each outdoor unit.
• Never connect 220 – 240 V power to the terminal blocks (
,
, etc.) for control wiring.
(Otherwise, the system will fail.)
• Perform the electric wiring so that it does not come to contact with the high-temperature part of the pipe.
The coating may melt resulting in an accident.
• After connecting wires to the terminal blocks, provide a trap and fix wires with the cord clamp.
• Run the refrigerant piping line and control wiring line in the same line.
• Do not turn on the power of the indoor unit until vacuuming of the refrigerant pipes completes.

Remote controller wiring
2-core non polarity wire is used for the remote controller wiring.
1
Connect the connecting wire to the terminal as identified with their respective numbers on the terminal block of
indoor and outdoor unit.
H07 RN-F or 60245 IEC 66 (1.5 mm
2
or more)
2
Insulate the unsheathed redundant cords (conductors) with electrical insulation tape.
Process them so that they do not touch any electrical or metal parts.
