How to wire
1. Remove the mounting screws (2 pieces), open the
electrical control box cover.
2. Connect the power supply wires and system
interconnection wires to the terminal block of the
electrical control box.
3. Tighten the screws of the terminal block, connect
the wires matching the terminal numbers (Do not
apply tension to the connecting section of the
terminal block.)
4. Close the electrical control box cover, attach the
mounting screws.

* Use 2-core shield wire (MVVS 0.5 to 2.0 mm² or
more) for the remote controller wiring in the
simultaneous twin system to prevent noise
problems. Be sure to connect both ends of the shield
wire to earth leads.
* Connect earth wires for each indoor unit in the
simultaneous twin system.

WARNING
Be sure to connect the earth wire. (grounding work)
Incomplete grounding may cause an electric shock.
Connect the earth wire properly following applicable technical standards.
Connecting the earth wire is essential to preventing electric shock and to reducing noise and electrical charges on

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 system interconnection wires off the valve on the gas side or pipes that have no heat
insulator.

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 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.
• That the valve is open.

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.

Annual maintenance
ndoor
power
inter-unit
For an air conditioning system that is operated on a regular basis, cleaning and maintenance of the indoor / outdoor
wiring
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.
