DANGER
Do not ground units to water pipes, telephone wires or
•
lightning rods because incomplete grounding could cause a
severe shock hazard resulting in severe injury or death, and
to gas pipes because a gas leak could result in an explosion
which could lead to severe injury or death.

NOTES
If the wiring is in a place where people it can be easily
1.
touched by people, install a ground-fault circuit interrupter
to prevent electric shock.
When using a ground-fault circuit interrupter, make sure to
2.
select one useful also to protection against overcurrent and
short-circuit.
When using a ground-fault circuit interrupter only for
grounding device, make sure to use a wiring interrupter
together.
The length of the transmission wiring and remote controller
•
wiring are as follows.
Length of the transmission wiring and remote controller wiring
Outdoor unit – Indoor unit
Max. 3280 ft.
(Total wiring length: 6560 ft.)
Indoor unit – Remote controller
Max. 1640 ft.

HOW TO CONNECT WIRINGS
9-1
Remove the front panel (upper).
(1)
High-voltage hole
Low-voltage hole
Terminal block
box cover
Top panel
Remove the terminal block box cover and the high-
(2)
voltage cap.
High-voltage cap
Pass the power supply wiring and the ground wire
(3)
through the top panel’s high-voltage hole (requires
use of conduit) and pass the remote controller wiring
and transmission wiring through the top panel’s
low-voltage hole.
Pass the included insulation tube (2) through the hole in
•
the panel before connecting the electric wires and the
ground wire to the terminal block (3P) shown in the
following diagram.
Then secure them in place with the included clamp
•
material (1) as shown in the following diagram to protect
them from external force from outside the unit.
Pass the included insulation tube (2) through the hole in
•
the panel before connecting the remote controller wiring
and transmission wires to the terminal block (6P) shown
in the following diagram.
Then secure them in place with the included clamp
•
material (1) as shown in the following diagram to protect
them from external force from outside the unit.
