HUMIDIFIER!
produces non-pressurized steam by means of electrodes immersed in the water
contained in the plastic steam generator cylinder. Electric current passes through the water between the
electrodes, heating the water into steam, which is then used to humidify the air.
The quality of the water used affects the operation of this unit, so the Elite Steam may be supplied
with untreated water, as long as this is drinkable and not softened or demineralized. The water
converted into steam is automatically replaced through an electric fill valve. Periodically, based on the
water quality, the unit will also drain some water to dilute the build-up of minerals in the steam
generator. In cases of high water mineral content, an activated carbon filter in series
with a particulate filter, no more than 5 microns is suggested.
This humidifier has been designed exclusively to directly humidify residential rooms or ducts, using
a distribution system. The installation, use and maintenance operations must be carried out according to

ble 1.a
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.

1.2 Cylinder Life
1.2.1 Basics of the Steam Cylinder
1.2.2 Water
1.2.3 Water Filtration
1.2.6 Structures Under Construction
The Steam Cylinder is the engine of the humidifier. As the humidifier operates and water is evaporated and minerals are left
behind. Much of these minerals are removed through the cylinder drain. Some are deposited on the walls of the cylinder and
the cylinder electrodes. When a lower section of the electrodes develop a thick coating, the water level is raised to expose
clean electrode surface. Eventually minerals cover the electrodes’ entire length with a thick coating and little electrical current
can pass between them resulting in poor steam output. The humidifier can sense the low amperage and will display the E6
Cylinder Exhausted error code. There are several factors that influence cylinder life.
Characteristics of water influence cylinder life and can vary greatly from place to place. Total mineral content of the water is
important. Equally important is what minerals are present in the water. Most water conditions result in flakey scale that
eventually fills the bottom of the cylinder until it can no longer function. Water with high silica content can result in a thin
glass-like coating on the electrodes that is highly insulating resulting in shorter cylinder life. Only cold water is to be used
Typically additional filtration of the incoming water supply is not necessary. If, however, mineral content is known to reduce
cylinder life excessively or if cylinder life proves insufficient then water filtration can be added. In most cases the addition of a
two element water filter can improve cylinder life. The filter should contain an activated carbon element and a particulate filter
element rated for 5 microns or less. Micron is a size measurement. The filter system should have a flow rate of at least
2 gpm. The activated carbon will absorb much of the mineral content while the particulate filter will catch any granular material
or sediment. It is important to remember that the increase in cylinder life will be accompanied by the need to replace filter
elements with each cylinder change.
Humidity load demands have an effect on cylinder life. Normal installations where humidity capacity is properly sized require
only intermittent periods where full humidifier capacity is required. This allows the water level in the cylinder to be increased
only as electrode segments become insulated. This tends to maximize cylinder life.
Extraordinary installations that require constant operation at full capacity reduce cylinder life. The water level in the cylinder is, on
average, much higher, and the electrodes become completely insulated more quickly. Installations like this may result in
cylinder life of less than 1000 hours.
The importance of providing adequate humidifier capacity should not be underestimated.
In high end construction projects, humidification is often required while the structure is being finished. Humidification is
necessary to protect and stabilize wood floors, trim and decoration. Humidification load, however, in an unfinished structure may
be five to eight times higher than when finished. Elite Steam humidifiers may be operated while construction is underway but,
reduced cylinder life is to be expected and budgeted for. Good practice dictates that the steam cylinders also be replaced once
the project is complete.

Another factor affecting cylinder life is the maximum production setting. A higher
production rate will result in a shorter cylinder life. For this reason DS-35 and RS-35
units are preset from the factory at 70%. Further reductions in Maximum Production
will extend cylinder life. See Figure 1.c. 100% 20%

The following water types are not acceptable:
1. Softened water as this will lead to foam, electrode corrosion and greatly shortened
cylinder life.
2. Water containing disinfectants or corrosion inhibiters, as these are potential irritants.
3. Industrial water, boiler water or water from cooling circuits.
4. Any potentially chemically or bacteriologically contaminated water.
5. Heated water.
3.3.2 Water Supply Connection
We recommend the connection between the fill valve and the water supply line by a
soft poly hose capable of absorbing the water hammering in order to avoid damage to
the fill valve itself. The water line may be routed through the back or through the
bottom of the unit. With poly tubing, a tubing support must be used to prevent tubing
collapse and leaks. The fitting then threads onto the fill valve inlet located on the
bottom of the humidifier using a 3/4” G connection. Note that there is a strainer built
into the fill valve fitting underneath the unit, which will require periodic
cleaning, so be sure to allow clearance for access.

3. Connect the steam and condensate hoses using the hose clamps supplied.
(Note: End support bracket supplied only with 0,9m (36”) and longer distributors.)
IMPORTANT: Allow 1 M ( 3 feet ) of straight duct downstream of the distributor pipes and nozzles for absorption of the steam. Always
allow 0.6M (2 feet) of straight duct upstream of the distributor pipes for evaporation of the steam. Turbulent air flow may require longer lengths.
3.4.2 Return Condensate Connection
The return condensate hose from the nozzle, etc. must be trapped. Coil the hose into a vertical loop and secure it
below the nozzle, etc. This trap prevents steam from being released into the cabinet. The hose end may be run
3.4.3 Steam Hoses
IMPORTANT WARNING: NINETY PERCENT (90%) OF ALL OPERATION PROBLEMS ARE CREATED BY IMPROPER STEAM
PIPING FROM THE HUMIDIFIER UNIT TO THE DUCT DISTRIBUTOR PIPES.
To avoid these problems, remember one simple fact when running the steam hose: steam naturally flows uphill,
and condensate naturally flows downhill. Run the steam hose or piping to avoid any kinks, sharp elbows, or low
spots that could collect to restrict the flow of steam to the distributor pipe, or the flow of condensate back to the
humidifier. Support the hose adequately to avoid sags, steam hose can droop after serveral years' service.

3.6 Control wiring
Elite Steam allows connection of any simple or automatic humidistat, and safety
devices such as high-limit humidistat, air flow proving switch, and remote on/off.
The humidifier is operated by the closing of a mechanical humidistat H, or by the closing
of a voltage-free remote contact CR, or alternatively by a combination of both. The
most common is a combination of a humidistat and pressure switch. The diagrams
in the figures show the connections to be made on the terminal block, in case of :
Fig. 3.u Operation performed by a simple enabling contact;
Fig. 3.t Operation controlled by an external mechanical humidistat;
Fig. 3.v A combination of both humidistat and pressure switch (most common).
Contact AB-AB:
• closed: humidifier enabled to produce steam
(production starts when humidistat closes);
• open: steam production is immediately stopped.
The remote on/off contact is usually a series of external potential-free contacts
that enable the humidifier to produce steam when all of them are closed, indicating the
duct/AHU is ready to accept steam. Connect the 12500 Pressure Switch NO and C
terminals to the AB-AB contacts.
For example,
• fan contact closes when fan is running;
• downstream cooling coil contact closes when coil is off;
• etc.
Contact IN-GND:
• closed: steam production starts if contact AB-AB is closed
• open: steam production is stopped after 5 sec.
