I. PRINCIPLE OF OPERATION
The Aprilaire
®
Fresh Air Exchanger is designed to
remove indoor air pollution and provide a constant
supply of fresh air to the home. The special
EnergyMax
®
transfer core utilizes the indoor con-
ditioned air to pre-heat or pre-cool the incoming fresh
air depending on the season. During the winter
season, the cross-flow design EnergyMax transfer core
allows the incoming fresh air to be preheated by the
warm stale air being exhausted, thereby reducing the
energy required by the heating system to warm the air
to your desired temperature. This same process
removes heat and moisture from the incoming air
stream during the summer. The Aprilaire
®
Fresh Air
Exchanger provides a comfortable and healthy
environment for your entire home year round, with only
minimal maintenance requirements and trouble-free
quiet operation. For optimum benefits, the PerfectAire
unit has been designed for continuous operation.

There has been more evidence lately to indicate
that the air in our homes is more seriously polluted
than the outdoor air even in the largest and most
industrialized cities. Since research indicates that peo-
ple spend approximately 90% of their time indoors,
this poses a health risk. In addition, people who may
be exposed to indoor air pollutants for long periods of
time are often those most susceptible to the adverse
affects of indoor air pollution. These groups include the
young, the elderly, the chronically ill, and especially
those suffering from respiratory or cardiovascular dis-
eases. The levels of pollutants from individual sources
may not pose a significant or serious risk to health by
themselves. However, most homes have more than
one source that contributes to indoor air pollution and
an accumulative affect of these sources is cause for
concern.
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. Be sure to register your warranty with
us for our records and your protection.
