IV. ANNUAL MAINTENANCE
V. ANNUAL SUMMER SHUTDOWN
For best performance, we recommend that you replace the
Humidifier Pad in your Humidifier annually.
To obtain a replacement:
• Call your heating and air conditioning dealer.
• Look in the Yellow Pages under Heating & Air Conditioning Contractors.
• If none of the above are successful and you still need information,
please feel free to write us or send an email to our website.
For Models *HUMD200ABM00B, *HUMD300ABA00B
close the bypass damper .
AUTOMATIC HUMIDIFIER CONTROL:
Humidifiers controlled by the Automatic Humidifier Control require no
control adjustment. Shut off the water supply to the humidifier by closing
the saddle valve.
MANUAL HUMIDIFIER CONTROL:
For humidifiers controlled by a Manual Humidifier Control, simply turn the
Control to the “Off” position. Shut off the water supply to the humidifier
by closing the saddle valve.
III . EFFECT OF WATER CHARACTERISTICS
To check the humidifier operation, set the Humidifier Control above the click
point, make sure that the water saddle valve is open and that there is
electricity to the humidifier. Generally, the furnace and blower motor must be
operating for the Humidifier Control to function. After the humidifier has
operated for several minutes and water is entering the humidifier and coming
out at the drain, reduce the Humidifier Control setting below the click point
and the humidifier should automatically shut off. Now set the Humidifier
Control dial at the recommended inside relative humidity, depending on the
outside temperature. Follow the suggested settings prior to a drop in the
outside temperature.
Additional Information
Be sure to keep fireplace dampers closed when not in use. They provide
an excellent escape route for heat, as well as humidity. Humidity is lost at
an even faster rate than heat because water vapor tends to seek its own
level and your humidifier would not be able to replace it even when
running at full capacity.
On occasion, indoor moisture producing activities such as clothes drying,
cooking, showers, etc., may raise the relative humidity level higher than it
should be, even though the Humidifier is not operating. Telltale
indications, again, are condensation or frost on cold surfaces such as
windows, doors, walls, etc. If such condensation persists for several
hours, your home should be ventilated to dissipate the potentially
damaging excess moisture.
Your humidifier will operate effectively using either hot, cold, hard or
mechanically softened water. Whether to use available tap water, even
though it may be quite hard, or chemically softened water, is a common
concern to homeowners when installing a humidifier. Because of the
humidifier’s design, most of these solids are effectively controlled by
flushing them down the drain.
Water used in homes contains varying amounts of minerals. The residue
remaining as a result of hard water evaporation is primarily calcium and
magnesium components and is usually quite hard, scaly, and dense.
Residue from softened water tends to be soft and fluffy and has a greater
volume than hard water residue. The service life of a Humidifier Pad may
be extended by using hard water, but in either case, the Humidifier Pad
should be changed once a year. This is why proper maintenance is
important and necessary. Service hot water 140°F maximum, is
recommended with flow through, drain type units for increasing capacity.
