Electric Heaters
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).
