ELECTRIC HEATER DATA (cont)
LEGEND
*Values shown are for single-point connection of electric heat acces-
sory and air handler.
NOTES:
1. Electrical resistance heaters are rated at 240 v, 480 v, or 575 v. To
determine heater capacity (kW) at unit nameplate multiply the
240-v, 480-v, or 575-v capacity (kW) by the factor shown in the
table below for the unit voltage.
2. The following equation converts kW of heat energy to Btuh:
kW x 3,412 = Btuh.
3. Heater contactor coils are 24 v and require 8 va holding current.
4. Electric heaters are tested and ETL approved at maximum total
external static pressure of 1.9 in. wg.
5. MCA and MOCP values apply to both standard and alternate fac-
tory-supplied motors.
6. Approximate shipping weight for CAELHEAT001A00-015A00 is
55 lb each, CAELHEAT016A00-027A00 is 60 lb each, and
CAELHEAT028A00-039A00 is 75 lb each.
