1. HOW THE ELITE STEAM HUMIDIFIER WORKS
1.1 Basic Operation
The Elite Steam Humidifier is an electrode humidifier. Unlike heating
elements, electrode steam humidifiers produce steam for humidification
by passing electric current through the water between metal electrodes
inside the plastic steam generator cylinder. Steam output is directly
proportional to the conductivity of the water and the amount of electrode
immersed in the water. Test the water prior to installation with a
conductivity tester (use GFI #5539 or CGF #GF-AP-2 or similar).
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 (4)
prevents the unit from filling too quickly or with too much pressure. The
water flows up the fill tube (2) and into the fill cup (3). Water then flows
over the dam in the fill cup (3), which creates a 1” air gap to prevent
backflow of contaminated water into the feed lines, through the fill tube
(6) and into the bottom of the steam cylinder (5). Any backflow or
overflow of water travels through the overflow hose (13) to the drain.
As the water fills the cylinder, it will reach the electrodes (7) and electrical current will begin to flow. As the water continues to
fill the cylinder, the current will increase. This is monitored by an amperage transformer connected to one of the power wires
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 probe (9) or if current rises too much, the drain pump
(11) will be activated to drain away some water and reduce the current flow to acceptable levels. Note that any time the drain
pump is activated, the tempering valve (10) will be opened for tempering the hot drained water down to 140°F / 60°C in
accordance to local and national standards (See Figure 1.a.).
Periodically, based on the incoming water conductivity, the unit will activate the drain pump (11) and drain water to reduce
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 pump (11).
If the Elite Steam Humidifier remains powered but idle (i.e. without producing steam) for more than 72 hours (3 days), the
cylinder will automatically be emptied of water and will not refill until the unit is restarted. 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.
