•
Install the remote control unit with a distance of 5 m between the re-
mote control unit and the grille photocell as the criteria.
However, when installing the remote control unit, check that it operates
positively.
CAUTION

POWER
WARNING
(1) The rated voltage of this product is 230 V A.C. 50 Hz.
(2) Before turning on the verify that the voltage is within
the 198 V to 264 V range.
(3) Always use a special branch circuit and install a spe-
cial breaker to supply power to the air conditioner.
(4) Use a circuit breaker matched to the capacity of the air
conditioner. (Install in accordance with standard)
(5) The circuit breaker is installed in the permanent wir-
ing. Always use a circuit that can trip all the poles of
the wiring and has an isolation distance of at least 3
mm between the contacts of each pole.
(6) Perform wiring work in accordance with standards so
that the air conditioner can be operated safely and posi-
tively.
(7) Install a leakage circuit breaker in accordance with the
related laws and regulations and electric company
standards.
CAUTION
(1) The power source capacity must be the sum of the air
conditioner current and the current of other electrical
appliances. When the current contracted capacity is in-
sufficient, change the contracted capacity.
(2) When the voltage is low and the air conditioner is diffi-
cult to start, contact the power company the voltage
raised.
(3) This air conditioner must be connected to a power
source that has an electrical impedance of 0.25
Ω
or
less or has a supply current of 100 A or greater. If the
power supply does not meet the specifications, con-
tact the power company.

HOW TO CONNECT WIRING TO THE TERMINALS
A. For solid core wiring (or F-cable)
(1) Cut the wire end with a wire cutter or wire-cutting pliers, then strip
the insulation to about 25 mm (15/16”) of expose the solid wire.
(2) Using a screwdriver, remove the terminal screw(s) on the terminal
board.
(3) Using pliers, bend the solid wire to form a loop suitable for the
terminal screw.
(4) Shape the loop wire properly, place it on the terminal board and
tighten securely with the terminal screw using a screwdriver.
B. For strand wiring
(1) Cut the wire end with a wire cutter or wire-cutting pliers, then strip
the insulation to about 10 mm (3/8”) of expose the strand wiring.
(2) Using a screwdriver, remove the terminal screw(s) on the terminal
board.
(3) Using a round terminal fastener or pliers, securely clamp a round
terminal to each stripped wire end.
(4) Position the round terminal wire, and replace and tighten the ter-
minal screw using a screwdriver.
