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. 20 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)

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 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.
(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) Securely earth the power cord plug.
(5) Do not use the earth screw for an external connector.
Only use for interconnection between two units.
FINISHING
(1) Insulate between pipes.
● For rear, right, and bottom piping, overlap the connection pipe
heat insulation and indoor unit pipe heat insulation and bind
them with vinyl tape so that there is no gap.
● For left and left rear piping, butt the connection pipe heat insula-
tion and indoor unit pipe heat insulation together and bind them
with and vinyl tape so that there is no gap.
●
For left and left rear piping, wrap the area which accommodates
the rear piping housing section with cloth tape.
●
For left and left rear piping, bind the connection cord to the top
of the pipe with vinyl tape.
●
For left and left rear piping, bundle the piping and drain hose
together by wrapping them with cloth tape over the range within
which they fit into the rear piping housing section.
CONDUIT CONNECTOR
(2) Temporarily fasten the connection cord along the connection pipe
with vinyl tape. (Wrap to about 1/3 the width of the tape from the
bottom of the pipe so that water does not enter.)
(3) Fasten the connection pipe to the outside wall with a saddle, etc.
(4) Fill the gap between the outside wall pipe hole and the pipe with
sealer so that rain water and wind cannot blow in.
(5) Fasten the drain hose to the outside wall, etc.
