Options

Spare Parts Package Includes	18-Month Warranty (12-Month Standard) (2) Electric Heaters and (2) Heater Gaskets (2) Sight Glass Tubes and (4) Washers (1) Pressure Control (1) Contactor
Motorized Automatic Flush and Drain (MAFD)	During Start-Up before steam pressure is accumulated, the Motorized Automatic Flush and Drain option cycles fresh water through the boiler for 0-300 seconds (Factory set for 180 seconds or three (3) minutes). As old water is drained out, fresh water will be cycled in. This drain valve will not open if boiler pressure exceeds 5 psi, and the electric heaters are locked out during flush cycle.
Single Service Transformer	Supplied standard with all portable steam generators, the Single Service Transformer steps down the primary high voltage to provide 120 VAC Single Phase (1Ø) to the controls; with this option, only the one (1) primary high voltage supply is required.
5-Micron Water Filter	2-stage, 5-micron water filter installed into incoming water line to reduce sediment, dirt, rust, chlorine, and even odor from incoming water supply.
Manual Low Water Reset⁴	Manual Low Water Reset trips if the electric heaters shut-off because of a low water condition. Reset must be manually pressed to resume steam production.
Portable Mounting Includes	Wheels Push Handle Single Service Transformer Option
Water Feed Booster Pump	Supplied standard on any steam generator with an operating pressure higher than 15 psi. The Water Feed Booster Pump increases your incoming water pressure to overcome the operating pressure of the steam generator. The Pump requires a 5-150 psi water supply with a minimum flow rate of 2 gpm.

¹ Each Electro-Steam™ electric steam generator requires two (2) power supplies: One (1) primary high voltage supply and one (1) secondary 120 VAC 1Ø, 50/60 Hz supply. Each generator is custom built to accommodate only one (1) customer specific high voltage supply for the heaters. 120 VAC 1Ø, 50/60 Hz must also be supplied for the controls, unless the Single Service Transformer option is added.
² Calculations are based off of a 212ºF boiler feed-water temperature. Boiler feed-water temperatures that range between 60ºF and 140ºF, are approximately 80% to 90% of the calculated values shown. Boiler feed-water must not exceed 140ºF.
³ Wetted Surfaces
⁴ A Manual Low Water Reset Button is supplied standard with every steam generator, but it is disabled. If this Reset Button is required as per your local boiler codes, simply plug the two attached wires into the PC-Board terminals labeled "Reset".
