To reset the end of service life on an Armstrong HumidiClean HC-4100 Series Steam Humidifier, follow these steps:

1. Power down the unit.
2. Reset the dip switches to their previous settings (Factory Defaults: HC-4100 = 1000 hours, HC-4300 & HC-4500 = 500 hours).
3. Power the unit up at the breaker.
4. Press and hold the “RESET” button for at least 20 seconds to reset the EOL time.
5. Allow the unit to run for at least one hour.
6. Power the unit down at the breaker.
7. Set the dip switches to the desired settings.
8. Power the unit up at the breaker.

These steps will restore proper operation.

    Installation Please read and save these instructions. The Armstrong HumidiClean humidifier converts ordinary tap water or purified water to steam for distribution to raise the relative humidity level. To allow HumidiClean to function to its full capability, be certain to install in accordance with Armstrong recommendations.
  • Page 3 3. Site Selection. The humidifier should be installed in an easily accessible location. Do not install the unit where malfunction of the humidifier might cause damage to non-repairable, unreplaceable or priceless property. Refer to Installation section for other details regarding site selection. Figure 3-1 HC-4100/4145/4300 Installation Hose Clamp Full Size Tee...

A wall mounting bracket and lag screws are provided for mounting on 16" (41 cm) centers. The operating weight of the unit is 186 lb. (84 kg). A clearance of 24" (61 cm) on the right side and in front of the cabinet is required for servicing.

Refer to Figure 8-1 (the overall wiring diagram) for more information. A duct mounted high limit humidistat is recommended to prevent over-saturation of the duct air. Use an on-off controller that opens on fault (high humidity).
  • Page 10 Start-Up Procedure Before turning on the power: 1. Examine the electrical compartment for any loose or disconnected component wiring. Check all high voltage screw terminal connections at contactor, terminal strip, fuse block & power module for tightness. 2. Open side door (HC-4100, 4145, 4300). Remove tank access panel by unscrewing two black knobs.
  • Page 11 As HumidiClean continues to produce steam, the unit will accumulate and memorize the heating element active time for the purpose of defining a drain cycle and service life (this memory is not affected by power outages). When the HumidiClean heating elements have been on for the dip switch drain frequency setting, the unit activates the drain and fill solenoids and begins draining the tank.
  • Page 12 ii) Allow the solution to work until the boiling action ceases. iii) Clean the water level electrodes, using an emery cloth. See Page 15 for complete instructions. iv) Check water level canister for debris. v) Replace the electrodes. vi) Ensure drain lines are free of leaks and secure. vii) Fill the tank with water and drain.

    e) Allow the unit to run for at least one hour. Power the unit down at breaker. g) Set the dip switches to the desired settings. See Page 22 for the dip switch settings. h) Power the unit up at breaker.

  • Page 14 Replacing the Ionic Beds 1. Turn off steam generation switch and allow unit to completely drain. 2. Cut power at circuit breaker. 3. Unlock and open front and side doors (HC-4100/4145/4300). 4. (Caution: Tank will still be quite warm and should be allowed to cool.) Unscrew two black knobs (6 knobs HC-4500) holding access panel and remove.
  • Page 15 10. Turn on power at circuit breaker. 11. Depress and hold in the reset button to the left for 20 seconds. All the LED’s will blink together indicating the accumulated hours memory has been reset to zero. The unit should now be heard filling.

Consult humidistat manufacturer or Armstrong for proper troubleshooting/ calibration procedures. 3. If humidifier generates steam with the humidistat disconnected.
  • Page 19 2. Check humidistat demand signal at low voltage terminal strip. It should be close or at 100%. 3. If humidifier is a three phase model, verify all three phases of power are present and equal. 4. Check amperage draw on all high voltage power lines with a clamp on amp meter. They should be same or very close to amperage rating on the humidifier’s nameplate if the humidistat demand is 100%.
