d)Insert the wrapped tubing into the hole in the wall.

e)Hang the indoor unit on the rear panel.

f)Using a Phillips screwdriver, take out the screws on the earth plate. (Fig. 26a KHS09, 12 models only) Remove the earth plate.

g)Remove the lock nut from the conduit connector. Insert the conduit connector through the opening from the underside of the electrical component box. After insertion, Fit the screw at the top of the con- duit connector into the cut-out. (Fig. 26b). Position the earth plate over the conduit connector, allowing the connector and wires to extend through the hole in the plate. Next, attach the conduit connector to the earth plate by replacing and tightening the lock nut (Figs. 26c and 26d). Then re-attach the earth plate to the electrical component box with the 2 screws.

h)Give some play to the inter-unit wiring from the out- door unit to the corresponding terminals on the termi- nal base. (See Wiring System Diagram on page 10.)

WARNING

Be sure to refer to the Wiring System Diagram label inside the electrical component box and carry out the correct field wiring. Wrong wiring can cause the unit to misoperate or result in a fire hazard.

Check local electrical codes and any specified wiring instructions or limitations.
