Procedure
1 Strip the insulation from the wire (20 mm).
2 Connect the connection wires between the indoor and outdoor
units so that the terminal numbers match (see wiring diagram
below). Tighten the terminal screws securely. We recommend a
flathead screwdriver to tighten the screws.
See also caution 2 under "Notes to observe" on page 9 for
wiring guidelines.

Use the specified wire type and connect it securely (A).
Firmly secure the wire clamp so that wire terminations do not
receive external stress (B).
Shape wires so that the service cover and stop valve cover fit
securely (C).
CAUTION
1. In case the use of stranded conductor wires is
unavoidable for one reason or another, make sure to
install round crimp-style terminals on the tip.
Place the round crimp-style terminal on the wire up to
the covered part and fasten the terminal with the
appropriate tool.

2. When connecting the connection wires to the terminal
board using a single core wire, be sure to perform
curling.
Not executing the connections properly may cause
heat and fire.
Strip the wire at terminal block:
1 Strip wire end to this point
2 Excessive strip length may cause electrical shock
or leakage.
