Introduction
Thank you for your recent Lennox®Healthy Climate™Humidifier purchase. We
sincerely appreciate your business and are pleased to add your name to our
growing list of customers. Now, please take a few minutes and read this booklet.
This will familiarize you with the benefits you will receive from the equipment
you just purchased and help you understand the routine maintenance that will
be required.
I. Principle of Operation
You have purchased a humidifier that operates on the evaporative principle.
Itwill provide the proper relative humidity (see operating instructions) all during
the heating season. It is very possible that you have questions concerning what
your new humidifier can do for you, and what you should do to receive maximum
benefits from it. This booklet is intended to answer these questions.
The humidifier operates in conjunction with the furnace blower motor. When
the humidistat calls for humidity and the blower motor is operating, water flows
to the distribution pan located at the top of the unit. The water is uniformly distributed across the width of the pan and through a scientifically designed system
of outlets. It flows by gravity over the evaporative media. Dry, hot air is moved
through the moisture-laden evaporative media where evaporation takes place.
The now-humidified air carries moisture in vapor form throughout the home.
The correct water flow is determined by an orifice in each unit. When
the unit is operating, there will be a small, steady stream of water to drain,
which flushes away most of the trouble-causing minerals. Do not use the
saddle valve to regulate the water flow. It is designed to be completely opened
or closed.
The minerals and solid residue not trapped by the replaceable evaporative
media are flushed down the drain. The drain also eliminates the problems
caused by stagnant water. This is the most effective and least expensive
method to dispose of trouble-causing minerals.
Trouble-free performance and minimum maintenance are assured by the
design features of the Lennox Healthy Climate Humidifier. All unit housing parts
that come in contact with water are non-metal and will never rust or corrode.
Neither heat nor water will affect them under normal operating conditions.
The evaporative media, designed especially for uniform, high evapora-
tion, and the Scale Control Insert also efficiently trap mineral deposits which
are often the cause of damage to working parts in ordinary humidifiers. No
“white dust” can be distributed throughout the living quarters. The evaporative
media must be in good condition to assure high capacity trouble-free performance. It should be changed annually.
The granular coating in the bottom of the distribution tray is designed to
provide equal distribution of water to each of the openings assuring an even
flow of water over the evaporative media. Do not clean the mineral scale off the
bottom of the water distribution tray at the end of the humidification season.
The scale provides an excellent track for the water to follow. This is actually
what we try to simulate with the synthetic coating in the bottom of the tray. If
the coating is removed, it is not necessary to purchase a new distribution tray.
You can accomplish the same uniform performance by applying a small
amount of liquid dish soap over the entire lower surface of the water distribution tray. This will allow the water to flow evenly through each of the openings.
