					Mounting slot   
					1) Before wiring, confirm the rated voltage of the unit as   
					shown on its nameplate, then carry out the wiring   
					closely following the wiring diagram.   
					2) Provide a power outlet to be used exclusively for   
					each unit, with a power supply disconnect and circuit   
					breaker for overcurrent protection provided in the   
					exclusive line.   
					Fig. 17   
					3) To prevent possible hazard due to insulation failure,   
					the unit must be grounded.   
					4) Each wiring connection must be done tightly and in   
					accordance with the wiring system diagram. Wrong   
					wiring may cause the unit to misoperate or become   
					damaged.   
					5) Do not allow wiring to touch the refrigerant tubing,   
					compressor, or any moving parts of the fan.   
					6) Unauthorized changes in the internal wiring can be   
					very dangerous. The manufacturer will accept no   
					responsibility for any damage or misoperation that   
					occurs as a result of such unauthorized changes.

					(For C2432 and CL2432)   
					Narrow tube   
					IMPORTANT   
					To prevent heat loss and wet floors due to dripping of   
					condensation, both tubes must be well insulated with   
					a proper insulation material. The thickness of the insu-   
					lation should be a minimum 5/16 inch. (Fig. 35)   
					Fig. 32

					Spanner   
					Indoor unit   
					After a tube has been insulated,   
					CAUTION   
					never try to bend it into a nar-   
					row curve, as this may cause   
					the tube to break or crack.   
					Outdoor unit   
					Fig. 33   
					(1) At this time, the 2 refrigerant tubes (and electrical   
					wire if local codes permit) should be taped together   
					with armoring tape. The drain hose may also be   
					included and taped together as 1 bundle with the   
					tubing.   
					Insulation   
					(Field supply)

				(2) Wrap the armoring tape from the bottom of the out-   
					door unit to the top of the tubing where it enters the   
					wall. As you wrap the tubing, overlap half of each   
					previous tape turn. (Fig. 36)

					(3) Clamp the tubing bundle to the wall, using 1 clamp   
					approx. every 4 ft.   
					Fig. 35   
					NOTE   
					Do not wind the armoring tape too tightly since this will   
					decrease the heat insulation effect. Also be sure the con-   
					densation drain hose splits away from the bundle and   
					drips clear of the unit and the tubing.   
					Clamp   
					Insulated tubes   
					4-6. Finishing the Installation   
					After finishing insulating and taping over the tubing, use   
					sealing putty to seal off the hole in the wall to prevent   
					rain and draft from entering. Fig. 37 shows refrigerant   
					tubing taped separately from the drain hose.
