CONNECTING THE CABLE TO THE OUTDOOR UNIT
• Use a solid or stranded wire.
Connecting cable: AWG14
Power supply cable: AWG10
• Use copper wire.
• Follow local electrical codes.
• Use a double insulated cable with 600 V insulation.
(1) Strip the copper wires.
(2) Remove the cable cover.
(3) Attach the conduit connector to conduit holder with the lock nut.
(4) Pass the cables through the conduit connector.
(5) Remove the cable holder and connect the cables.
(6) Fix the cable sheath with the cable holder and the screw.
(7) Double-check that the cable is securely in place.
(8) Attach the cable cover.
Caution:
• Be very careful not to confuse the terminal connections. Wrong
cabling may damage the internal control circuit.
• Be sure to connect the cable to match the markings on the outdoor
unit's terminal board and those of the indoor unit.
• Be sure to put the cable leads deep into the terminal board and
tighten up the screws. Poor contact can cause overheating or fire,
or malfunction.
• Be sure to use a disconnect switch. Follow the local and state elec-
trical codes.
