4.) CALCULATIONS AND DATA SHEETS
4.1) HEATER POWER & VOLTAGE RATINGS
LG Model units use 3 Heaters to meet the required (KW) POWER from the customer’s
specified INPUT VOLTAGE. Each heater comes in 5 different (KW) POWER RATINGS and
4 different VOLTAGE RATINGS.

NOTE: 380-425V heaters are not usually rated for 380-425V. They are usually 208-240V heaters
that have been re-stamped 380-425V and wired in series.
4.2) TOTAL POWER RATING CALCULATIONS
The HEATER POWER RATING and NUMBER OF HEATERS are used to calculate the
TOTAL POWER RATING. Since the HEATER POWER RATINGS are in Kilowatts, they
must be multiplied by 1000 to convert them to Watts.
DEFINITIONS:
PT = Total Power Rating
PH = Heater Power Rating
xH = Number of Heaters
