*Figured at 1 KW (3413 Btu) = 4.1 gallons at 100°F temperature rise.
To determine recovery rate per minute, divide recovery rate per hour by 60.
This Instruction Manual covers two models of commercial
electric water heaters:
These two models are equipped from the factory with different
controls.
In this Instruction Manual, one model is factory equipped with
a surface mounted thermostat/ECO combination control and is
referred to as a surface-mount control model.
The other model is equipped with an electronic control system
