NOTICE
Precautions when laying power wiring:
▪ Do not connect wiring of different thicknesses to the
power terminal block (slack in the power wiring may
cause abnormal heat).
▪ When connecting wiring which is the same thickness,
do as shown in the figure below.
▪ For wiring, use the designated power wire and connect
firmly, then secure to prevent outside pressure being
exerted on the terminal board.
▪ Use an appropriate screwdriver for tightening the
terminal screws. A screwdriver with a small head will
damage the head and make proper tightening
impossible.
▪ Overtightening the terminal screws may break them.

To connect the electrical wiring on the
outdoor unit
NOTICE
▪ Follow the wiring diagram (delivered with the unit,
located at the inside of the service cover).
▪ Fix the earth wire to the stop valve attachment plate so
that it does not slide.
▪ Make sure the electrical wiring does NOT obstruct
proper reattachment of the service cover.
