Grounding

WARNING
Be sure to connect the ground wire. (grounding work)
Incomplete grounding may cause an electric shock.
Connect the ground wire properly following applicable technical standards.
Connecting the ground wire 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 a ground wire, you may experience an electric shock.

Finishing

After the refrigerant pipe, inter-unit wires, and drain pipe have been connected, make sure they are supported and
fixed in place for the entire length.
Keep the power wires and system interconnection wires away from all factory wiring and piping.

Test run

•
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 208-230 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 specifi ed in the Owner's Manual.

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.
