General Filters Incorporated 1. HOW THE ELITE STEAM HUMIDIFIER WORKS 1.1 Basic Operation The Elite Steam Humidifier is an electrode humidifier. Unlike heating Figure 1.a. 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.
General Filters Incorporated 1.2 Cylinder Life 1.2.1 Basics of the Steam Cylinder The Steam Cylinder is the engine of the humidifier. As the water is evaporated inside the cylinder, minerals are left behind. Much of these minerals are removed through the cylinder drain, however, some are deposited on the walls of the cylinder and the cylinder electrodes. When a lower section of the electrodes develops a thick coating, the water level is raised to expose clean electrode surface.

General Filters Incorporated 3. INSTALLATION 3.1 Positioning The Elite Steam Humidifier has been designed for wall mounting and, since it is an electrode 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 minimum clearances must be maintained around the unit for safety and maintenance. (See Table 3.a. and Figure 3.a.) DO NOT introduce steam into duct that has interior insulation. Figure 3.a.
General Filters Incorporated 3.2.2 Fastening to the Wall Using the supplied template, drill mounting holes (as indicated by “A” in Figure 3.c.) in the wall. Secure the Elite Steam Humidifier firmly to the wall using the supplied screws and anchors. Figure 3.c.
General Filters Incorporated 3.3 Plumbing 3.3.1 Water Characteristic 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 0.45 L/min or 0.
General Filters Incorporated 3.3.3 Water Drain The Elite Steam Humidifier requires a connection to a drain. The drain pipe may be routed out the bottom of the unit using the included grey 90° angle fitting. The drain pipe can be MIN 1-1/2” ID PVC, CPVC or polypropylene. The drain pipe is not glued or otherwise attached to the (supplied) 90° drain elbow, so it must be supported by itself. A coupling (field supplied) should be used.
General Filters Incorporated 3.4.2 Steam Manifold Injection (Additional Kit Required) (Used when air flow is between 600 and 1000 CFM.) If a duct steam manifold is to be used, select an accessible location on the duct, allowing at least 36” of straight duct (no elbows or obstructions) after the point where the nozzle/manifold will be installed and the clearances can be maintained as per the following drawings. To mount the steam manifold, cut or drill a 2-1/2” hole in the duct (See Figure 3.j.).

General Filters Incorporated 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. Figure 3.p. 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 Figure 3.p.) All wiring must be in accordance with local, state and national electric codes.
General Filters Incorporated Figure 3.w. 3.6.1 Connect the GFX3 Humidistat for ON/OFF Operation (Figure 3.w.) 1. 2. 3. 4. 5. 6. Remove the humidistat from the base, squeeze the louvered base at the top and bottom. To remove the humidistat from the wall, lift up on the humidistat and pivot top away from wall. Before wall mounting, remove the black foam gasket. Before return air duct mounting, remove the breakout piece. If return air duct mounting, route wires between humidistat and base.

General Filters Incorporated 4. START-UP 1. Before starting, check that there are no water leaks and that the electrical components 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 10 minutes by piping water directly into the drain without sending it into the humidifier. This will eliminate any scale or residue that may cause foam when boiling. 4.
General Filters Incorporated During the cleaning, the electrodes are powered and water in the cylinder rises 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 un-powered (the drain pump and the drain tempering valve are activated for 3 minutes). General Filters, Inc. recommends performing two cleanings when starting a new boiler.
General Filters Incorporated 5.5 Resetting the Hour Counter With Each New Replacement Cylinder The hour counter should be reset every time the cylinder is changed in order to reset and restart the internal maintenance timer: 1. Switch the Elite Steam Humidifier off. 2. Press and hold both buttons “Reset” and “Drain” and switch the Elite Steam Humidifier back on. When the wrench blinks; release buttons. 3. Press and hold “reset” until the display shows 03. : DO NOT confirm any value higher than 04.
General Filters Incorporated 5.7 Alarms In the event of an alarm, the red alarm LED will flash, the alarm relay will close, and the alarm code will flash in the display. Multiple alarms will flash in sequence, alternating with the main display. Pressing the “reset/sel” button for 2 seconds will reset the alarms, although still active alarms will continue to display.
General Filters Incorporated 6. TROUBLE SHOOTING Table 6.a Problem The humidifier does not turn on The humidifier does not start operation The humidifier fills with water without producing steam Excess humidity or moisture in the duct Water leaks on to the floor below Water in the cylinder turns black Heavy arcing occurs within hours of start-up Humidifier continuously fills and drains without producing steam 20 | P a g e Causes 1.

General Filters Incorporated 7. MAINTENANCE 7.0 • • • • Periodic Checks After one hour of operation: Check that there are no significant water leaks. Every fifteen days: Check operation for water leaks and the general condition of the cylinder. Check that during operation there is no arcing between the electrodes. Every three months: Check operation for water leaks and, if necessary, replace the cylinder. Check that there are no blackened parts of the cylinder.

General Filters Incorporated Figure 10.f. 10.8 Hose Routing and Connections Connect the steam hose to the stainless elbow fitting located at the bottom of the manifold and secure with the hose clamp provided. See Figure 3.m. for additional hose routing recommendations. Do not force the steam hose onto the stainless fitting - apply some water to the inside of the hose and ease the hose onto the fitting. Connect the condensate hose to the molded barbed fitting on the right. (See Figure 10.
General Filters Incorporated : The standard steam unit comes with 6 feet (1.8m) of steam hose. The RMB unit comes with 9 feet of 3/8” ID hose. The maximum total length of rubber steam hose is 3.65m (12 feet). The maximum total length of insulated copper tubing may be up to 6.1m (20 feet). The maximum combined allowed length of steam hose and insulated copper tubing is 9.75m (32 feet). In all cases, minimize sharp bends and elbows. Use 2 - 45° elbows instead of 90° elbows.
