(main power switches, circuit breakers, wires, conduit
connectors and wire terminals) have been properly selected
according to the electrical data given in “Technical Catalog”.
Make sure that the components comply with National
Electrical Code (NEC).
2
Use the shielded twist pair cable for the control cable
between the outdoor unit and the indoor unit, the control
cable between indoor units and the remote control switch
cable of PC-ARF(PE).
3
Check to ensure that the power supply voltage is within
RIWKHUDWHGYROWDJH
4
Check the capacity of the electrical wires. If the power
source capacity is too low, the system cannot be started due
to the voltage drop.
5
Check to ensure that the earth wire is connected.

• Do not operate the system until all the check points have been cleared.
a.
Check to ensure that the electrical resistance is more than 1 megohm, by measuring the resistance between ground and the
terminal of the electrical parts. If not, do not operate the system until the electrical leakage is found and repaired. Check to
ensure that the stop valves of the outdoor unit are fully opened, and then start the system.
b.
Check to ensure that the switch on the main power source has been ON for more than 12 hours, to warm the compressor oil
by the crankcase heater.
• Do not touch any of the parts by hand at the discharge gas side, since the compressor chamber and the pipes at the discharge
side are heated higher than 90ºC.
