Installation Manual For Electric Wiring

5. Electric wiring

WARNING

DANGER OF BODILY INJURY OR DEATH

TURN OFF ELECTRIC POWER AT CIRCUIT BREAKER OR POWER SOURCE BEFORE MAKING ANY ELECTRIC CONNECTIONS. GROUND CONNECTIONS MUST BE COMPLETED BEFORE MAKING LINE VOLTAGE CONNECTIONS.

(1)Selection of size of power supply and interconnecting wires. Precautions for Electric wiring

Electric wiring work should be conducted only by authorized personnel.

Do not connect more than three wires to the terminal block. Always use round type crimped terminal lugs with insulated grip on the ends of the wires.

Use copper conductor only.

Select wire sizes and circuit protection from table below. (This table shows 20 m length wires with less than 2% voltage drop.)

(2)Wiring connection

Make wiring to supply power to the outdoor unit, so that the power for the indoor unit is supplied by terminals.

Note: remember to connect the black terminal of indoor unit with the black terminal of outdoor unit properly using the connecting wire in the accesory bag,and connect the blue terminal of indoor unit with the white terminal of out terminal as the same(For heat pump model).For cooling only unit,just connect the black terminalof indoor unit with the black terminal of outdoor unit properly.Otherwise the wired controller will display "E4" or "E6" malfunction refer to Page.16.
