TABLE 1 – Operation Guide
Models *HUMD300ABA00B and *HUMD500APA00B with Automatic
Humidifier Control:
(for Manual Humidifier Control – see page 5)
Your Automatic Humidifier Control is installed in the cold air return.
During the first heating season, your Automatic Humidifier Control needs
to be set initially to match your home’s condition. Please follow these
steps when adjusting your Control (refer to Figure A).
1. Turn the dial setting knob to “5,” which is within the normal range.
During the next 24-48 hours it may be necessary to adjust the dial for
more or less humidity, depending on your personal comfort and home’s
requirements. Refer to the “Operation Guide” (Table 1).
2. During the coldest portion of the first heating season, minor
adjustments may be necessary. This is dependent upon your individual
home construction, refer to the “Operation Guide” (Table 1).
Condition
Solution
Condensation on windows
Reduce the setting on the control dial
by 1 increment.
Lack of humidity
Increase the setting on the control dial
by 1 increment.
Humidifier does not operate
Turn dial to “Test.” Make certain furnace
and blower are operating. If humidifier
still doesn’t operate, consult your air
conditioning and heating dealer.
Humidifier won’t shut off
Turn dial to “Off.” If humidifier continues
to operate, consult your air conditioning
and heating dealer.
Test mode
System operation is checked by setting the
knob to “Test.” Make certain furnace and
blower are operating. Humidifier will
operate for one minute.
The relative humidity in your home
will now be accurately controlled
to meet your needs and should not
need further adjustment during
future heating seasons. Make note
of the dial setting in the event you
temporarily move the knob when
performing annual maintenance of
the Humidifier.
II. OPERATING INSTRUCTIONS
FIGURE A
Your new humidifier has been installed to operate in conjunction with
your furnace. When the Humidifier Control calls for humidity and the
furnace blower is operating, water flows to the distribution tray located at
the top of the humidifier. The water is evenly distributed across the width
of the tray and over the Humidifier Pad. Dry, hot air is moved through this
moisture laden Humidifier Pad where it is evaporated into a vapor. This
humidified air is circulated throughout your home. Humidified air helps to
reduce static electricity, prevents wood furniture from drying out, helps
prevent nasal passages from becoming too dry and makes your home
more comfortable.
Important Notes About Your Humidifier:
When the humidifier is operating, there will be a small, steady stream of
water to drain. Do not use the saddle valve to regulate the water flow. The
saddle valve is designed to be either completely open or completely closed.
Although your humidifier incorporates a self-flushing action, the
Humidifier Pad will develop mineral build-up over time.
To assure high
capacity, trouble-free performance the Humidifier Pad should be
replaced annually.
For water distribution trays with a synthetic fabric liner:
The
synthetic fabric liner provides an even water flow over the Humidifier Pad.
It is normal for some mineral deposits to form in the distribution tray as it
dries out between humidification cycles. These deposits can actually help
distribute water in the tray, but if they form enough to block the openings,
they should be removed as described in the “Periodic Preventative
Maintenance” section of this manual.
For water distribution trays with a granular coating:
The coating on
the bottom of the distribution tray provides an even flow of water over
the Humidifier Pad.
Do not clean the mineral scale off the bottom of
the distribution tray at the end of the humidification season.
The
scale actually provides an excellent track for the water to follow.
