4.4) ACTUAL POWER RATING CALCULATIONS

Because the HEATER VOLTAGE RATINGS only come in 4 different voltages, and there
are so many different voltages in the field, the TOTAL POWER RATING is only completely
accurate if the VOLTAGE IN is exactly equal to the HEATER VOLTAGE RATING. This
means, in most cases, the TOTAL POWER RATING is not completely accurate. The
AMERAGE and INPUT VOLTAGE can be used to calculate the ACTUAL POWER
RATING.

4.5) STEAM CAPACITY CALCULATIONS

Steam Capacity Calculations are based on the impossible feed water temperature of 212°F.
WARNING – Anything above 140°F will cause damage to water solenoid and pump.
