    The unit continues to fill until the current matches demand or the high water sensor detects a high water level.  The NHTC/PC repeats the fill and boil down cycle repeatedly to match output to demand.  Over time minerals in the water will adhere to the cylinder’s electrodes. The humidifier will automatically fill to a higher water level to maintain full capacity during the life of the cylinder.

  • Page 48: Selecting An Rh Setpoint

    Duct High Limit – The duct high limit is intended to prevent saturation and wetting in duct work at high load conditions. NORTEC recommends a setting of 85% for the duct high limit. It may be necessary to reduce this setting If the duct work is very cold or in contact with exterior cold surfaces.

    Removing the Cylinder Warning  Disconnect main power at the external disconnect before any servicing.  The plumbing and electrical compartments contain high voltage components and wiring. Access should be limited to authorized personnel.  Cylinder may be hot, take care when handling. 1 Drain the existing cylinder.

  • Page 66: Drain Valve Cleaning

    Drain Valve Cleaning Always clean the drain valve before installing a new cylinder. Scale from the spent cylinder may have fallen into the drain valve and could prevent its proper operation. To properly clean the drain valve it must be removed and disassembled. Note: Be sure to reattach the green ground wire to reduce the risk of electrical shock.

    4 Shut off power to the humidifier with the external disconnect. 5 Close the supply water shut-off valve. Note: As long as the NHTC/PC is powered, it will automatically drain the cylinder when there has not been a call for humidity for an extended period of time. This feature will reduce or prevent the possibility of corrosion of the electrodes and the accumulation of algae and bacteria growing in the cylinder.
