8. ELECTRICAL WIRING

(1) Match the terminal block numbers

and connection cord colors with
those of the outdoor unit. Erroneous
wiring may cause burning of the
electric parts.

(2) Connect the connection cords firmly

to the terminal block. Imperfect
installation may cause a fire.

(3) Always fasten the outside covering

of the connection cord with the cord
clamp. (If the insulator is chafed,
electric leakage may occur.)

(4) Always connect the ground wire.

1. INDOOR UNIT SIDE

(1) Remove the electric component box.

(3) Remove the electric component box cover.

Remove the three tapping screws.

Be careful not to pinch the lead wires
between the electric component box and
base.
