Connection of wiring between units, earth wire and for the remote controller cord (Refer to Fig. 27)
•
Wiring the units and earth wire Remove the control box lid and connect wires of matching number to the
control block for wiring the units (4P) inside. And connect the earth wire to the earth terminal. In doing
this, pull the wires inside through the hole and fix the wires securely with the included clamp (4).
•
Remote controller cords Remove the control box lid and pull the wires inside through the hole and con-
nect to the terminal block for remote controller (P1, P2). (no polarity) Securely fix the remote controller
cord with the included clamp (4).

•
Protect the wire and the wiring through hole area for
wirings of the transmission, earth and the remote
controller in order to prevent the intrusion of water
and small animals into the air conditioner after the
system is wired.
• Halve the sealing pad - small (13), then wind round
each one to the respective wiring lines.
• After all the wiring connections are done, fill in any
gaps in the through holes with putty or insulation
(procured locally) to prevent small animals and in
-
sects from entering the unit from outside. (If any do
get in, they could cause short circuits in the control
box.)
•
Outside the machine, separate the weak wiring
(remote controller cord) and strong wiring (interunit,
earth, and other power wiring) at least 50 mm so
that they do not pass through the same place to-
gether. Proximity may cause electrical interference,
malfunctions, and breakage.
