Introduction

Thank you for your recent 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. It will 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 humidifier control calls for humidity and the blower motor is
operating, water flows to the distribution tray located at the top of the
humidifier. The water is uniformly distributed across the width of the tray
and through a scientifically designed system of outlets. It flows by gravity
over the humidifier pad. Dry, hot air is moved through the moisture-laden
humidifier pad 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
humidifier. When the Models 5000, 6000 and 7000 humidifiers are
operating, there will be a small, steady stream of water to drain,
which flushes away most of the trouble-causing minerals. When the
Model 4000 humidifier is operating properly, water will not be visible
in the drain. 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
humidifier pad 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.

There are some homes where drain facilities are not accessible or
available. The Model 4000 humidifier is designed to satisfy these
applications.

Trouble-free performance and minimum maintenance are assured
by the design features of the humidifier. All humidifier housing parts that
come in contact with water are non-metal (except for the valve and
humidifier pad) and will never rust or corrode. Neither heat nor water
will affect them under normal operating conditions.

The humidifier pad, designed especially for uniform, high
evaporation, 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 humidifier pad must be in good condition to assure
high capacity trouble-free performance. It should be changed annually,
with the exception of Model 4000, which should be changed at least
twice per heating season.
