Wiring
[Wiring procedure]
1) Strip the insulation from the wire (3/4 inch (20mm)).
2)
Connect the inter-unit wires between the indoor and
outdoor units so that the terminal numbers match.
Tighten the terminal screws securely. It is recommended
that a slot-head screwdriver be used to tighten the screws.
3) Be sure to match the symbols for wiring and piping.
4)
Pull the wire lightly to make sure that it does not
disconnect.
5) After completing the work, reattach the shield cover and
right side plate to their original positions.
• Attach so that the shield cover hooks (2 locations) are
securely engaged.

Note: Take care to ensure that all wiring
between indoor unit and outdoor unit has a
consistent connection. Any splices can cause
communication errors.
: The Room A and Room B terminal
blocks, as well as the Room C and Room D
terminal blocks, are actually integrated.
Recommend using AWG14, stranded and insulated wire for connections
between indoor and outdoor units.
Local code always supersedes recommendation.

no lifting of the shield cover or
other structural parts.
