Provide a disconnect switch with an integrated lock-out feature of size required to provide adequate fan motor starting current. See Tables 4-6 for unit electrical data.

!WARNING

ELECTRICAL SHOCK HAZARD

Failure to follow this warning could result in personal injury or death.

Do not use gas piping as an electrical ground. Unit cabinet must have an uninterrupted, unbroken electrical ground to minimize the possibility of personal injury if an electrical fault should occur. This ground may consist of electrical wire connected to unit ground lug in control compartment, or conduit approved for electrical ground when installed in accordance with NEC (National Electrical Code); ANSI/NFPA 70, latest edition (in Canada, Canadian Electrical Code CSA [Canadian Standards Association] C22.1), and local electrical codes.

!WARNING

FIRE HAZARD

Install disconnect switch and power wiring in accordance with all applicable local codes. See Fig. 14-16 and the unit label diagram. Connect power wiring with 1/4-in. ring terminal.

Fan motors are factory-installed on all units. Indoor-fan contactors are located in the fan contactor box behind the side access panel (see Fig. 15 and 16). Wire the thermostat to the 24-v control circuit terminal block located in the side of the fan contactor control box, according to Fig. 17 or the unit label diagram. If the air handler is part of a split system, complete the wiring from the condensing unit to the thermostat shown in Fig. 17.

Failure to follow this warning could result in intermittent operation or performance satisfaction.

Do not connect aluminum wire between disconnect switch and fan coil unit. Use only copper wire.
