Electric Heaters

50TC units may be equipped with field- - installed
accessory electric heaters. The heaters are modular in
design, with heater frames holding open coil resistance
wires strung through ceramic insulators, limit switches
and a control contactor. One or two heater modules may
be used in a unit.
Heater modules are 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. 27 - - 29.
Not all available heater modules may be used in every
unit. Use only those heater modules that are UL listed for
use in a specific size unit. 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 2 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).
