On a call for humidity, the
Elite Steam
controller will open the water fill valve (1) and
allow water to enter the cylinder. A flow restrictor (2) prevents the unit from filling too
quickly or with too much pressure. The water flows up the fill tube (3) and into the fill
cup (7). Water then flows over the dam in the fill cup (7), which creates a 1” air gap to
prevent backflow of contaminated water into the feed lines, and through the fill tube
(4) and into the bottom of the steam cylinder (11). Any backflow or overflow of water
travels through the overflow hose (5) to the drain.
As the water fills the cylinder, it will reach the electrodes (10) and current will begin
to flow. As the water continues to fill the cylinder, the current will increase, and this
is monitored by an amperage transformer connected to one of the power wires (9)
and located on the electronic controller. When the desired current is reached, the fill
valve will close (1) and the water will then begin to warm and produce steam. If the
water reaches the cylinder full probes (8) prior to reaching the desired current rises
too much as the water fills the cylinder, the drain valve (13) will be activated to drain
away some water and reduce the current flow to acceptable levels. Note that, any
time the drain valve is activated, the tempering valve (14) will be opened for
tempering the hot drained water down to 140 degrees F/ 60 degrees C in accordance
to local and national standards.
Periodically, based on the incoming water conductivity, the unit will open the drain valve (13) and drain some water to reduce the mineral
concentration. Every 120 hours the unit automatically drains to remove mineral sediment on the bottom of the cylinder. A strainer (12) in
the cylinder helps to prevent mineral debris from jamming the drain valve (13). In case Elite Steam remains powered but idle, i.e. without
producing steam, for more than 72 hours (3 days), the cylinder will be emptied to not have stagnant water inside.
If there is no water in the cylinder, there will be no current flow and no steam production. The electrodes do not burn out, but they will
eventually become completely coated with mineral and the cylinder will then need to be replaced. Cleaning cylinders may cause electrode
damage, therefore voiding its warranty. See 7.2.2 maintenance section on page 21.
1.1 Basic Operation
Elite Steam
is an electrode humidifier. It produces steam for humidification by
passing electric current through the water between metal electrodes in the plastic
steam generator cylinder. There are no heating elements. Steam output is directly
proportional to the conductivity of the water, and the amount of electrode immersed
in the water.
