1. HOW THE ELITE STEAM WORKS 1.1 Basic Operation The Elite Steam is an electrode humidifier. It produces steam for humidification 3 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 The Steam Cylinder is the engine of the humidifier. As the humidifier operates 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.
Indoor Air Temp ◦ 2. MODELS There are two basic models available for different water conditions. Duct Steam Injection Fig. 2.a MODEL LIST PART NUMBER DS 50 DS 50 LC DESCRIPTION Duct steam injections 58 gallons per day (20 Lbs per hour) 220-240V Duct steam injections 58 gallons per day (20 Lbs per hour) 220-240V DS 50 / DS 50 LC +030222065 Rev. 1.2 PARTS INCLUDED Humidifier with Duct Mount Kit and Humidity GFX50 control. Humidifier for Low Conductivity water. Includes Duct Mount Kit and GFX50 control.
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). Do not mount on furnace, air handler or ductwork. Certain clearances must be maintained around the unit for safety and maintenance. Clearance Dimensions F 3.2 Mounting 3.2.
3.2.2 Fastening to the wall Drill the wall according to the drilling template supplied; then secure DS 50 / DS 50 LC firmly to the wall by the screws and anchors supplied. Do not mount on furnace, air handler or ductwork. Dimensions are in millimeters and [inches] Fig. 3.e DS 50 / DS 50 LC +030222065 Rev. 1.
3.3 Plumbing 3.3.1 Water Characterisitc Requirements The humidifier must be supplied with water with the following characteristics: • pressure between 20psi and 110psi or 0.1 and 0.8 MPa (1 and 8 bar) • temperature between 33°F and 104°F or 1°C and 40°C • flow-rate minimum of 0.83 L/min or 0.
3.3.3 Water Drain The DS50 and DS50 LC requires a connection to a drain. The drain line may be routed out the back or bottom of the unit using the included angle fitting. The drain line can be 1-1/4” PVC, CPVC or polypropylene. The drain line is not glued or otherwise attached to the humidifier so it must be supported by itself. A coupling should be used.

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.
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 up hill, and condensate naturally flows downhill.
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. See Fig. 3.o GROUND TERMINAL BLOCK All wiring must be in accordance with local, state and national electric codes.

Do not reverse these connections. Connect GFX50 terminal A OUT 6 to Elite Steam terminal IN. See fig. 3.t. NOTE: 1. MODULATING OPERATION requires Elite Steam signal type be changed, ON SEC. 5.1.1 page 19 The GFX50 is capable of ON-OFF operation. See the GFX50 manual.

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.
During the cleaning, the electrodes are powered and water is filled in until it touches the high-level sensor or the phase current equals 20A, whichever occurs first. After either of the events is detected, the boiler is fully discharged with the electrodes unpowered (the drain pump and the drain tempering valve are activated for 3 minutes). Warming the filling water helps washing out any mould release or dirt. General Filters, Inc. recommends to do two cleanings when starting a new boiler.

6. TROUBLE SHOOTING Problem Causes Solutions The humidifier does not turn on 1. No electrical power 2. On/off switch of the humidifier in position 0 (open) 3. Control connectors improperly connected 4. Blown fuses 5. Transformer failure 1. Check the safety devices upstream from the humidifier and the presence of power 2. Close the switch on the panel: position I 3. Check that connectors are properly inserted in terminal block 4. Check the condition of fuses 5.
7. MAINTENANCE 7.1 • • • • Periodic checks After one hour of operation: Check that there are no significant water leaks. Every fifteen days or no more than 300 operating hours: Check operation, that there are no significant water leaks and the general condition of the cylinder. Check that during operation there is no arcing between the electrodes. Every three months or no more than 1000 operating hours: Check operation, that there are no significant water leaks and, if necessary, replace the cylinder.
