Connect the earth line properly following applicable technical standards.
Power supply wire
Connecting the earth line is essential to preventing electric shock and to reducing noise and electrical charges on the
outdoor unit surface due to the high-frequency wave generated by the frequency converter (inverter) in the outdoor
unit.
If you touch the charged outdoor unit without an earth line, you may experience an electric shock.

FINISHING

After the refrigerant pipe, inter-unit wires, and drain pipe have been connected, cover them with finishing tape and
clamp them to the wall with off-the-shelf support brackets or their equivalent.
Keep the power wires and indoor/outdoor connecting wires off the valve on the gas side or pipes that have no heat
insulator.

TEST RUN

• Turn on the circuit breaker at least 12 hours before starting a test run to protect the compressor during
startup.
To protect the compressor, power is supplied from the 220-240 VAC input to the unit to preheat the compressor.
• Check the following before starting a test run:
• That all pipes are connected securely without leaks.
• That the valve is open.
If the compressor is operated with the valve closed, the outdoor unit will become overpressurized, which may
damage the compressor or other components.
If there is a leak at a connection, air can be sucked in and the internal pressure further increases, which may cause
a burst or injury.
• Operate the air conditioner in the correct procedure as specified in the Owner's Manual.
