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.
4.1 Start-Up Checklist
Before starting the humidifier, the following should be checked:
• Water is connected, the line has been flushed, and external valves are open.
• Min 1-1/2” ID drain is installed, but not connected to 90° elbow (supplied), 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 25 or 30A power fuses are installed and intact.
• All AWG10 control wiring is done and tested.
• The airflow switch is wired to open on air flow loss.
• The Hi-limit humidistat is wired to open on humidity rise above set point.
• Remove two screws securing control board. Unit wires should be checked to make sure they and all connectors are tight.
• The steam hose(s) are run correctly with no sags or kinks and sloped properly according to the manual.
• Condensate hose(s) are run correctly with no sags or kinks and sloped properly according to the manual.

4.3 Starting the Elite Steam Humidifier
• Insure that the external power is turned on.
• Push the top part of the ON/OFF button so that the “I” part is in (See #11 at right). The yellow
power LED will be lit. The Elite Steam Humidifier is now ready to operate.
• When there is a call for humidity, the Elite Steam Humidifier will close its power relays and send
power to the electrodes in the plastic steam generator. The green Operation LED will light,
indicating that operation has begun.
4.4 Starting With A New Steam System or Replacement Steam Cylinder
When starting with a new cylinder, you should activate the cylinder cleaning function as follows:
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
then release the two buttons.
3. Press and hold “reset” until the display shows 04.
: DO NOT confirm any value higher than 04. If 05 or higher is displayed, press “reset” until the display goes
back to the normal operating mode and restart from step 1.
4. Press “drain” (minimum 1 second): the cleaning starts and the display shows PC.

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. After the cleaning ends, the humidifier begins its regular function. When starting the unit with a new or empty cylinder, it may take a
significant amount of time (hours) for the unit to build up enough mineral concentration to reach rated capacity. This time can be shortened by
the addition of a teaspoon of salt or ¼ of an antacid tablet through the steam outlet on top of the cylinder.
5. Operating the Elite Steam Humidifier
5.1 Displaying Information
By pressing the “reset” button for 2 seconds, the display will loop from amperage to production in % of the maximum production to
the hour counter and back to amperage:
Figure 5.a
1. Amperage: it is the value of the current that flows through the water, causing it to boil (default display).
2. Production %: it is the current production expressed as a percentage of the humidifier’s capacity.
3. Hour counter: expressed in tens; for instance, when the display shows 13 the real hour value will be between 130 and 139
hours.
5.2. Select Signal Type
The Elite Steam Humidifier is pre-set for the included GFX3 humidistat (signal type 0). If the included humidistat is used, this section
may be omitted. If another humidistat is used, review this section to see if changes are needed.
1. Switch 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 the two buttons.
3. Press “Reset” until the display shows 02. : DO NOT confirm any value higher than 04. If 05 or higher is
displayed, press “Reset” until the display goes back to the normal operating mode and restart from step 1.
4. Press “drain” (minimum 1 second) to confirm: the display shows “P1” then the current signal type and “set”.
5. Press “Reset” to change signal type between 0 and 1:
0 = On-Off humidistat such as the GeneralAire “M” or “GFX” series humidistat.
1 = external 0...10 Vdc modulating signal such as the GeneralAire® ADCD series humidistat.
6. Press “drain” (minimum 1 second) when done to confirm the new value of P1 and exit to the normal operating mode.
7. Switch Elite Steam Humidifier off: you can now proceed with connecting the control wiring.
5.3. Changing the Maximum Production
The Maximum Production feature can be adjusted between 20% to 100% of the nominal production in steps of 5% in order to suit
the environmental characteristics. DS25 Maximum production is factory set at 70%.
1. Switch Elite Steam Humidifier off.
2. Press both and hold both buttons “Reset” and “Drain” and switch Elite Steam Humidifier back on. When the wrench blinks;
release the two buttons.
3. Press “reset” until the display shows 01. : DO NOT confirm any value higher than 04. If 05 or higher is
displayed, press "reset" until the display goes back to the normal operating mode and restart from step 1.
4. Press “drain” (minimum 1 second) the display shows “P0” then the current Maximum Production Percent and “set”.
5. Press “reset” to change the Maximum Production in steps of 5% between 20% and 100%.
6. Press and hold “drain” (minimum 1 second) when done to confirm the new Maximum Production and exit to the normal
operating mode.
5.4 Activating Manual Drain
Press and hold the “drain” button on the front of the unit until the cylinder is drained. Note: Water will continue to flow from the
tempering valve after the cylinder is empty.

5.6 Using the GFX3 Humidistat
Press to select OFF, AUTO (if outdoor sensor is connected) or MANUAL mode.
OFF mode:
The humidifier is turned off.
MANUAL mode:
The GFX3 will work to maintain the single humidity selected. You can set your desired humidity
level by pressing or . The humidifier will turn ON or OFF according to your manual setting.
(The humidifier will operate when the measured relative humidity falls more than 2% below the set
point.) Humidity will have to be lowered when weather is colder or if condensation is suspected.
AUTO mode:
The GFX3 will automatically raise the humidity as the outdoor temperature increases. This provides the highest possible humidity.
The GFX3 will automatically lower the humidity as temperatures drop. This minimizes the risk of condensation on cold surfaces like
windows. You can adjust the Auto Humidity Index Set Point from 0 (low) to 10 (high) by pressing or . The Humidity Index is
based on the outdoor temperature and indoor humidity. The humidifier will switch ON/OFF according to the calculated auto humidity
index set point. Lower Index settings are for older homes with less insulation and vapor barriers. Higher Index settings are for newer
homes with complete vapor barriers, triple pane windows and high R value insulation. If condensation occurs reduce Index setting by
2 points until condensation stops.
NOTE If the outdoor temperature sensor fails, flashes and the unit will default to MANUAL mode.
To toggle between indoor / outdoor temperature and indoor humidity: Press .
To change the temperature unit: Press °C / °F.
To set the temperature / humidity offset in MANUAL or AUTO mode:
1. Simultaneously press and when viewing the temperature or humidity reading.
2. Use or to change the setting (-3 to 3).
3. Press and simultaneously or wait 5 seconds to confirm, then move onto the next setting.
: DO NOT allow excess humidification.
Excess humidity can cause condensation and enable mold and mildew growth.
