ELECTROSTATIC DISCHARGE (ESD)

Precautions and Procedures

ElectricalCAUTION

Electrostatic discharge can affect elec­ tronic components. Take precautions to neutralize electrostatic charge by touching your hand and tools to metal prior to handling the control.

MAKE-UP

BOX

Right Side

FIGURE 63

The unit is equipped with a field make-up box. The make- up box may be moved to the right side of the furnace to fa­ cilitate installation. Secure the excess wire to the existing harness to protect it from damage.

Refer to figure 64 for field wiring, schematic wiring diagram and troubleshooting.

The power supply wiring must meet Class I restrictions. Protected by either a fuse or circuit breaker, select circuit protection and wire size according to unit nameplate.

NOTE - Unit nameplate states maximum current draw. Maximum Over-Current Protection allowed is 15 AMP. Holes are on both sides of the furnace cabinet to facilitate wiring.

Install a separate (properly sized) disconnect switch near the furnace so that power can be turned off for servicing. Before connecting the thermostat check to make sure the wires will be long enough for servicing at a later date. Make sure that thermostat wire is long enough to facilitate future removal of blower for service.

Complete the wiring connections to the equipment. Use the provided unit wiring diagram and the field wiring diagram shown in figure 64. Use 18-gauge wire or larger that is suit­ able for Class II rating for thermostat connections.

Electrically ground the unit according to local codes or, in the absence of local codes, according to the current Na­ tional Electric Code (ANSI/NFPA No. 70) for the USA and current Canadian Electric Code part 1 (CSA standard C22.1) for Canada. A green ground wire is provided in the field make-up box.

NOTE - The EL296UHE furnace contains electronic components that are polarity sensitive. Make sure that the furnace is wired correctly and is properly grounded.
