To improve the efficiency of your humidifier, and to reduce the possibility of a health hazard, it
is recommended that you take the following precautions:
• Follow the manufacturer’s recommended cleaning and maintenance instructions.
• The amount of minerals and other impurities in a water source can vary greatly, therefore the
frequency of cleaning the humidifier also varies.
• During the heating season, check for film or scale build up on the humidifier, evaporator pad,
and all moving parts on a monthly basis and establish a proper cleaning schedule.
• Do not allow film or scale to build up on the unit, evaporator pad, or any moving part which
will reduce the efficiency of the humidifier.
• At the end of the winter humidification season, drain and thoroughly clean your humidifier
as part of the summer shut down.
Be sure to install a new evaporator pad at the beginning
of the heating season before starting the humidifier.
Like your heating system and air conditioning unit, periodic maintenance and cleaning are
required to ensure the safe and efficient operation of your humidifier.

Description of Parts
Description of Parts
Solenoid Valve
All brass construction, controls the flow of water to the humidifier. The solenoid
valve will make a clicking sound as the plunger pin opens and closes. If this part
fails to operate correctly, water will flow continuously through the humidifier and
down the drain.
Conical Mesh Filter
Traps small particles in water supply that can clog and damage the solenoid valve.
Must be cleaned or replaced when water flow is impeded or humidification is
reduced.
Evaporator Pad
Allows water to evaporate as warm, dry air is drawn through it. Must be replaced
on a regular basis to maintain efficiency.
Fluid Restrictor
Located within the water tubing of the humidifier, it controls the amount of water
that flows through the humidifier.
Side Panels
Plastic construction and right or left hand discharge allows the unit to be installed
in a variety of installations. 1” wide collar allows for more secure installation of
bypass duct.
Water Distribution Tray
Felt wicking allows even distribution of water across surface of evaporator pad. As
mineral deposits build up, the tray will effectively channel the water through the
evaporator pad. Holes in tray must be cleaned periodically.
