50TC units may be equipped with field-installed accessory electric heaters. Each heater is a pre-assembled module, with heater frames holding open coil resistance wires strung through ceramic insulators, line-break limit switches and two control contactors for two-stage heating control.

The heater module is installed in the compartment below the indoor (supply) fan outlet. Access is through the indoor access panel. Heater modules slide into the compartment on tracks along the bottom of the heater opening. See Fig. 22, Fig. 23 and Fig. 24. Refer to the Electric Heater Kit Installation Instructions for complete details.

Not all available heater modules may be used in every unit. Use only those heater modules that are Carrier approved for use in a specific size. Refer to the label on the unit cabinet for the list of approved heaters.

Unit heaters are marked with Heater Model Numbers. But heaters are ordered as and shipped in cartons marked with a corresponding heater Sales Package part number. See Table 3 for correlation between heater Model Number and Sales Package part number.

NOTE: The value in position 9 of the part number differs between the sales package part number (value is 1) and a bare heater model number (value is 0).
