1. How The Elite Steam Works:

The Elite Steam is an electrode humidifier that produces steam
for humidification by passing electric current through water in the
steam plastic generator cylinder between metal electrodes. The
steam output is directly proportional to the conductivity of the
water and the amount of electrode immersed in the water.

When humidity is needed, the Elite Steam controller will open
the water fill valve and allow water to enter the cylinder. The
water flow is regulated by a flow restrictor to prevent
overfilling. Water then flows through the fill tube into the bottom
of the steam cylinder. Any backflow or overflow of water is
directed to the drain.

As the water fills the cylinder, it reaches the electrodes, and
current begins to flow. The current is monitored by an amperage
transformer connected to the power wires. When the desired current
is reached, the fill valve closes, and the water begins to warm and
produce steam. If water levels rise too high or current levels
increase excessively, the system will drain some water to maintain
proper levels.

2. Maintenance:

Periodically, based on incoming water conductivity, the unit
will open the drain valve to reduce mineral concentration. A
strainer in the cylinder helps prevent mineral debris from clogging
the drain valve. If the Elite Steam remains powered but idle for
more than 72 hours, the cylinder will be emptied to avoid stagnant
water.

Frequently Asked Questions (FAQ):

Q: How often should I clean my Elite Steam humidifier?

A: It is recommended to clean your humidifier at least once a
month to ensure optimal performance and prevent mineral
buildup.

Q: Can I use distilled water in the humidifier?

A: Yes, you can use distilled water in the Elite Steam
humidifier to minimize mineral deposits and prolong the life of the
unit.

Q: What should I do if my Elite Steam does not produce

steam?

A: If your humidifier is not producing steam, check the water
levels, ensure proper electrical connections, and clean any mineral
deposits that may be obstructing the electrodes.

We wish to save you time and money! We can assure you that the thorough reading of this manual will guarantee correct installation and safe use of the product described
WARNINGS
BEFORE INSTALLING OR HANDLING THE HUMIDIFIER PLEASE CAREFULLY READ AND FOLLOW THE INSTRUCTIONS AND SAFETY STANDARDS DESCRIBED IN THIS MANUAL AND ON THE LABELS ATTACHED TO THE Elite Steam. CAUTION: ALWAYS DISCONNECT THE MAIN POWER BEFORE OPENING OR SERVICING THE HUMIDIFIER! Elite Steam 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 and thus extend its life. This humidifier has been designed exclusively to directly humidify rooms or ducts, using a distribution system. The installation, use and maintenance operations must be carried out according to the instructions contained in this manual and on the labels applied internally and externally. IMPORTANT: BEFORE beginning installation:
· Check for shipping damage to cartons. Mark the shipping waybill accordingly. · Open cartons and check for any hidden damage. Mark the shipping waybill accordingly. · Check packing slip to ensure all items have been received. Notify General Filters of any shortages or damaged parts. You must notify General
Filters within 5 working days of any shortages. The conditions of the environment and the power supply voltage must comply with the specified values listed on the data label in the humidifier. All other uses and modifications made to the humidifier that are not authorized by the manufacturer are considered incorrect, and the manufacturer assumes no liability for the consequences of any such unauthorized use. Please note that the humidifier contains powered electrical devices and hot surfaces. All service and/or maintenance operations must be performed by qualified personnel who are aware of the necessary precautions and are capable of performing the operations correctly. Disconnect the humidifier from the main power supply before accessing any internal parts. The humidifier must be installed in accordance with all local and national standards.

1. How The Elit e St eam Works

Elite Steam is an electrode humidifier. It produces steam for humidification by passing electric current through the water in the steam plastic generator cylinder between metal electrodes. 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.

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.

10

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

12

level, the fill valve (1) will be closed to prevent overflow and the drain valve (13) will be opened to

11

drain away some water so as to move the water apart from the cylinder’s top. If the 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 °F / 60 °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. 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 or cleaned.

3. Installation
3. 1 Positioning
The Elite Steam has been designed for wall mounting and, since it is an atmospheric steam humidifier, should be placed close to the point where the steam will be used, to minimize the steam hose length (and the amount of condensate). Certain clearances must be maintained around the unit for safety and maintenance.

Fig. 3.e

3.2.2 Fastening to the wall Drill the wall according to the drilling template supplied; then secure Elite Steam firmly to the wall by the screws and anchors supplied.

Fig. 3.f 10

3. 3 Plumbing
3.3.1 Water supply The Elite Steam must be supplied with COLD potable water (not softened or demineralized) having the following characteristics:

Instant flow rate: Connection: Temperature limits: Pressure limits: Hardness limits: Conductivity:

0.12 gpm / 0.45 L/min 1/4″ O.D. Compression 34 to 104°F / 1 to 40 °C 15 to 116 psi / 1 to 8 bar <= 400 ppm CaCO3 125 to 1250 µ S/cm (micromhos)
Tab. 3.d

Fig. 3.g
The water feed line should be 1/2″ copper, PVC or poly tubing run to within 3 feet of the humidifier, then bushed down to 1/4″ O.D. poly to make the final connection to the 1/4″ O.D. compression fitting supplied with the unit. WARNING: WE RECOMMEND TO USE A SOFT POLY HOSE TO ABSORB THE WATER HAMMERING IN ORDER TO AVOID DAMAGE TO THE FILL VALVE. The water line may be routed through the back or through the bottom of the unit. With poly tubing, an insert should be used to support the tubing and prevent leaks. The fitting then threads onto the fill valve inlet located on the bottom of the humidifier. 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.
NOTE: softened water should NOT be used as it is generally corrosive to the electrode plating.
3.3.2 Water drain The Elite Steam also requires connection to a drain. The drain line may be routed out the back of the unit or the bottom of the unit using the included angle fitting. The drain water characteristics are:

Drain rate per hour: Instant drain rate: Connection: Typical temperature:

0.7 gph / 2.6 L/h 1.3 gpm / 5 L/min 1-1/4″ / 33 mm nominal diameter 140°F / 60 °C

Fig. 3.h
The drain line can be 1-1/4″ schedule 40 PVC or CPVC, 1-1/4″ copper, or 1-1/4″ Polypropylene. In all cases, the drain tube is slipped over the drain outlet on the bottom of the humidifier. It is not glued or otherwise attached to the humidifier, so it must be supported by itself. If 1-1/4″ schedule 40 PVC or CPVC is used, then a coupling should be used between the drain line and unit drain. The Elite Steam includes a drain tempering valve that opens whenever the drain valve opens and flushes cool feed water into the drain line to insure that the drain water temperature never exceeds 140 °F / 60 °C.
NOTE: Drain line must be trapped under the unit to prevent flash steam from condensing in the unit cabinet.

Or a stainless steel duct distributor:

Fig. 3.i

Fig. 3.l
To install the distributor pipes: 1. Cut a round hole in the side of the duct to match the steam pipe and condensate return. 2. Apply silicone sealant to the mounting plate and insert the pipe through the hole and secure it with 4 sheet metal screws. 3. Connect the steam and condensate hoses using the hose clamps supplied. (Note: end support bracket supplied only with 36″ and longer distributors.)
IMPORTANT: allow 2 feet of straight duct downstream of the distributor pipes for evaporation of the steam. Always allow 2 feet upstream. Turbulent air flow may require longer lengths.
3.4.2 Return Condensate Connection The return condensate from the distribution manifold or the Thru-wall blower unit shall be returned through the knockout on top of the humidifier and be inserted into the hole located on the top of the fill cup. See Fig. 3.k

3.4.3 Steam Hoses 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 up hill, and condensate naturally flows down hill. Run the steam hose or piping to avoid any kinks, sharp elbows, or low spots that could collect or 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. The following diagrams are to provide you with some guidelines. If you have a situation you are unsure of, please contact the factory for instructions.
Fig. 3.m IMPORTANT: Maximum length of rubber steam hose is 10 feet. Insulated copper tubing may be up to 20 feet. In all cases, minimize sharp bends and elbows ­ use 2-45° elbows instead of 90°s. Hose size = 7/8″ (22 mm). Hose size = 1-1/4″ (30 mm).

3. 5 Power wiring
Check that the power supply voltage to be connected matches the value indicated on the rating plate inside the electrical panel.
Insert the power and ground connection cables into the electrical panel compartment using the strain reliefs supplied, and connect to the terminals. An external fused disconnect must be installed.
All wiring must be in accordance with local, state and national electric codes.
NOTE: to avoid unwanted interference, the power cables should be kept separate from any control wiring.
All wiring must be in accordance with local, state and national electric codes.

4. Start-Up
IMPORTANT WARNINGS: 1. Before starting, check that the humidifier is in perfect condition, that there are no water leaks and that the electrical parts are dry; 2. Do not connect power if the humidifier is damaged or even partially wet!
When installation is completed, flush the supply pipe for around 10 minutes by piping water directly into the drain, without sending it into the humidifier; this will eliminate any scale or residues that may cause foam when boiling.
4. 1 Startup Checklist
Before starting the humidifier, the following should be checked:
Water is connected, the line has been flushed, and external valves are open. Drain is connected, run to an open drain, and has a trap under the unit. Electricity is connected in accordance with instructions, local codes and data labels in the unit. The power fuses are installed and intact. All control wiring is done and tested. Airflow switch is wired to open on air flow loss. Hi-limit humidistat is wired to open on humidity rise above set point. Unit wires have been checked to make sure they and all connectors are tight from shipping. The steam hose(s) are run correctly with no sags or kinks and sloped properly according to the manual. Condensate hoses are run correctly with no sags or kinks and sloped properly according to the manual.
