  • Page 2: Installation

    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. DANGER: ELECTRICAL SHOCK HAZARD HIGH VOLTAGES EXIST INSIDE THE HUMIDIFIER TO PROTECT YOURSELF AND OTHERS FROM ACCIDENTAL SHOCKS: Keep the humidifier locked during normal operation and store the key in a safe location away from the humidifier.
  • Page 3 Warning: Do not operate the supplied humidifier in combustible or explosive surroundings. Warning: Do not operate the supplied humidifier if there is any damage to the cabinet or any components in humidifier are damaged. Warning: The main switch should be a connection breaker which has over current and leakage current protecting functions per code EN60947-3 or EN60947-2 if point gap required by EN60947-3 can be fulfilled.

  • Page 4: Installation

    • This disconnecting switch should have leakage current protecting function. The max leakage current should be less than 30mA • The disconnecting switch should have a breaking capacity sufficient to interrupt the largest normal running current of loads. The breaking capacity required should be selected according to the table, 7-1, 7-2, 7-3 and 7-4 located on page 7.

  • Page 8 Duct Steam Distribution 1. The dispersion tube should be proper length. Verify correct size from Table 8-1. 2. Install dispersion tube(s) horizontally in duct so holes face upward. Air flow must be vertical up or horizontal. Do not restrict duct with a height of 200 mm (8”) or less. Installations over 10 m/s (2000 FPM) air velocity are not recommended.
  • Page 9 Area Steam Distribution The EHF-3 fan package (minimum of 2 required for HC-6500/6700) is designed to be hung on a wall to operate as a remote mounted, direct area discharge option. It incorporates a blower rated at 120v- 2.90 amps. CFM rating is 465 @ 1530 RPM. The fan package requires a separate 120 volt power sup- ply (optional step down transformer available).

Refer to Figure10-1 (the overall wiring diagram) for more inform ation. 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 17 Principle of Operation The HumidiClean humidifier converts ordinary tap water or purified water to steam for distribution to raise the relative humidity level. The demand for humidity is sensed by a humidistat or sensor which sends a control signal to the HumidiClean. The HumidiClean is connected to the power supply (208, 220/240, 380/400, 480 or 600 Vac) through a separate circuit breaker supplied by the customer.

    Removing the Tank, HC-6100/6300 Only 1. Operate menu to "MANUAL DRAIN" and allow unit to complete a deep drain. (Caution: Tank will still be quite warm). 2. Turn off circuit breaker. 3. Unlock and open front and side doors. Remove left side panel. 4.
  • Page 23 8. If drain valve and fill valve are both energized and water is below the 1/3 full level in the electrode canister (float canister for DI units), make sure the status of Steam Generation in menu is "STEAM GEN.". Perform continuity check to be sure. 9.
  • Page 24 4. If fuses are OK, check voltage to contactor coil. (a) If voltage is 24-28VAC at contactor coil, check coil resistance. It should be 8Ω with wires disconnected. If resistance is OK, check voltage drops across the contactor. (b) If no voltage to contactor coil, check continuity of wires from PC board to contactor. If continuity is OK, PC board is likely defective.
  • Page 25 Humidifier runs continuously, %RH is well under set-point. 1. Verify humidistat/RH sensor is wired correctly and dip switches (S2 & S3, See Fig. 10-1, 11-1 and 11-1) on the PC board are set correctly for the humidistat signal. 2. Check humidistat demand signal at low voltage terminal strip. It should be close or at 100%. 3.
  • Page 26 Dispersion tube spits water or water is present in duct Hint: It is very helpful to cut a small observation window in the duct and cover it with Plexiglas so the steam discharge from the manifold can be observed. This way the problem can be narrowed down to piping/steam quality (steps 1 and 2) or a condensation problem (steps 3 and 4).
  • Page 27 2 WATER LEVEL DROPPED BELOW LOW LEVEL - - The low level switch has not closed after 5 minutes of fill valve on time. This is only after initial start-up fill and boil-down sequence. Check: debris in water switch canister, defective fill valve, no water flow or low water pressure, drain valve stuck open, defective low water level switch (electrodes need to be cleaned).
