Installation of the Unit
(4). Electric wiring of indoor unit side
Remove the electric box cover from the electric box sub-assy and then connect the wire.
CAUTION!
● The power cord and the wire of the fresh air valve are high-voltage, while the
communication cord and connection wire of the wired controller are low-voltage. They
should run separately against electromagnetic interference.
● The high-voltage and low-voltage lines should pass through the rubber rings at different
electric box covers.
● Do not bundle the connection wire of the wired controller and the communication cord
together, or arrange them in parallel, otherwise improper operation would occur.
● The high-voltage and low-voltage lines should be fixed separately and securely, with
internal big clamps for the former and small clamps for the latter.
● Tighten the indoor/outdoor connection cord and power cord respectively on the terminal
boards with screws. Faulty connection may cause a fire.
● If the indoor unit connection cord (to the outdoor unit) and power supply are wired
incorrectly, the air conditioner may be damaged.
● Connect the indoor unit connection cord properly based on the corresponding marks.
● Ground both the indoor and outdoor units by attaching a ground wire.
● Unit shall be grounded in compliance with the applicable local and national codes.
