(1) Match the terminal block numbers and connection
cord colors with those of the outdoor unit.
Erroneous wiring may cause burning of the elec-
tric parts.
(2) Connect the connection cords firmly to the terminal
block. Imperfect installation may cause a fire.
CAUTION
(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.
(5) Do not use the earth screw for an external connector.
Only use for interconnection between two units.
ELECTRICAL WIRING (INDOOR UNIT)
HOW TO THE INSTALL THE INTER-UNIT WIRE HARNESS
1. Remove the screws, then remove the conduit holder.
2. Fasten the inter-unit wire harness to the conduit holder using the lock nut.
IMPORTANT: Refer to Fig. 19 about the length of inter-unit wire harness.
3. Use the screws to install the conduit holder with which Inter-unit wire har-
ness is included.
4. Remove the screws, then remove the wire clamper.
5. Connect inter-unit wire harness to the terminal.
Refer to the wiring diagram.
6. Use the screws to install the wire clamper.
ELECTRICAL WIRING (INDOOR UNIT)
1. Remove the screws, then remove the cord clamp.
2. Connect connection cord to the terminal.
Refer to the wiring diagram
3. Use the screws to install the cord clamp.
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 15/16
”
(25 mm) to 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 termi-
nal 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 3/8
”
(10 mm) to 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 termi-
nal screw using a screwdriver.
