EARTHING

WARNING

•

Be sure to connect the earth wire. (grounding work)

Incomplete grounding may cause an electric shock.

Connect the earth line properly following applicable technical standards.

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.

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.

•

Turn on the leakage 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.
