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.
