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.
• Apply the attached 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
• Use the specified wires for wiring connect the terminals. Securely fix them to prevent external forces applied
to the terminals from affecting the terminals.
Incomplete connection or fixation may cause a fire or other trouble.
• Connect earth wire. (grounding work)
Incomplete earthing cause an electric shock.
Do not connect earth wires to gas pipes, water pipes, lightning conductor or telephone earth wires.
• 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.
• Under no circumstances, the power supply wire or the indoor and outdoor connecting wire must not be
connected in the middle (Connection using a solderless terminal etc.)
Connection trouble in the places where the wire is connected in the middle may give rise to smoking and/or a fire.
CAUTION CAUTION
• For power supply specifications, follow the Installation Manual of outdoor unit.
• Do not connect 220 – 240 V power to the terminal blocks (
, ) for control wiring.
Otherwise, the system will fail.
• Do not damage or scratch the conductive core and inner insulator of power and system interconnection wires during
peeling them.
• 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.
• Do not turn on the power of the indoor unit until vacuuming of the refrigerant pipes completes.

Indoor unit power supplied from outdoor unit
• The outdoor unit power supply patterns vary on models.
*Number of wire × wire size
*Including earth line
Remote controller wiring
* The remote controller wiring length differs depending on the remote controller used. For details, refer to the Installation
Manual attached to the remote controller.
CAUTION CAUTION
The remote controller wire and Indoor / Outdoor connecting wires cannot be parallel to contact each other and cannot
be stored in the same conduits. If doing so, a trouble may be caused on the control system due to noise or other factor.
