<Method of wiring for the wiring between indoor unit
and outdoor unit, the earth wiring and the power supply
wiring>
(1) Remove the front panel (lower).
(2) Fix the each wire on the control box with the attached
clamp.
(3)
For wiring specifications, refer to the [DETAILS OF
STANDARD DEVICES].
CAUTION
Apply putty or insulation material (Field supply) without
any clearance on the wiring intake section to prevent small
animals from entering the unit.
(If small animals such as insects enter the inside of the unit, it
may cause short circuit in the control box.)
Connect the wire securely using designated wire and fix it
with attached clamp without applying external pressure on
the terminal parts.
Make sure the wiring and the control box lid do not stick up
above the structure, and close the control box lid firmly.
