PRINCIPLE OF OPERATION
With your purchase of this humidification system, you have
invested in a humidifier that operates on the evaporative
principle – nature’s own way of adding moisture – providing
optimum relative humidity (RH) throughout the heating
season. It is very possible that you have questions concerning
your new humidifier – questions on what it can do for you,
and what you should do to receive maximum benefits from it.
This booklet is intended to answer these questions.
Nature, in producing an invigorating comfortable day,
combines just the right temperature and the right amount
of moisture. EnviroAire IAQ humidifiers employ the same
principle, with refinements, to give you the optimum RH for
maximum allowable comfort all winter long.
The important considerations in the evaluation of a
humidifier are precise control, sufficient capacity, trouble-
free performance and minimum maintenance. The operating
principle of your EnviroAire IAQ humidifier provides all of
these advantages. Here, briefly, is the method: the EnviroAire
IAQ humidifier is installed to operate in conjunction with the
heating, ventilating, air conditioning equipment (HVAC)
blower. When the EnviroAire IAQ 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 water panel evaporator, the heart of the
humidifier. Dry, hot air is moved through the moisture-laden
water panel evaporator where natural evaporation takes
place. The now-humidified air carrying moisture in vapor form
(nature’s own way) is circulated throughout the home.
With bypass model EA-655, HVAC system airflow is drawn
through the humidifier from the supply duct to the return duct.
While the water going to the humidifier is hot, the flushing
water to the drain will be cold. The heat is extracted during
the evaporation process.
The correct water flow is
determined by an orifice provided with each drain
type humidifier. When the humidifier 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 open or closed.
The minerals and solid residue not trapped by the replaceable
water panel evaporator are flushed down the drain in the
EA-655 model. This is the most effective and least expensive
method to dispose of trouble-causing minerals. The drain
