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.

Connecting wire Power supply wire

•	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 380-415 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.

WARNING

Be sure to attach the provided clamp filter to the power supply wire in order to conform to EMC standards.

–106 – 8 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.

• 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.

11 ANNUAL MAINTENANCE

•For an air conditioning system that is operated on a regular basis, cleaning and maintenance of the indoor/outdoor units are strongly recommended.

As a general rule, if an indoor unit is operated for about 8 hours daily, the indoor/outdoor units will need to be cleaned at least once every 3 months. This cleaning and maintenance should be carried out by a qualified service person.

Failure to clean the indoor/outdoor units regularly will result in poor performance, icing, water leaking and even compressor failure.

12 AIR CONDITIONER OPERATING CONDITIONS

For proper performance, operate the air conditioner under the following temperature conditions:

Cooling operation	Dry valve temp.	–15°C to 46°C
Heating operation	Wet valve temp.	–20°C to 15°C

If air conditioner is used outside of the above conditions, safety protection may work.
