Your new humidifier has been installed to operate in conjunction with the
blower motor in your furnace. When the Humidifier Control calls for
humidity and the blower motor is operating, water flows to the distribution
tray located at the top of the unit. 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 now humidified air is circulated throughout your home.
Humidified air helps to reduce static electricity, reduces 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 on it over time. To assure high
capacity, trouble-free performance it should be replaced annually.
The granular coating on the bottom of the distribution tray is designed to
provide 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.
