YOUR COMFORT SYSTEM
Identifying Your System
Tal_efe time to thmiliarize yourself with the type of system you
have. This l_owledge will be of use in understanding the basic
operation of your new air conditioner.
The type of air conditioner you have purchased is a split system.
The split-system type has an indoor and an outdoor unit, each of
which contains a coil. These units are intercomaected by refrig-
erant tubes, as shown in Fig. 1.
Each unit has a rating plate affixed to itwhich provides necessary
inforlnation for specific identification of a unit. You should
falniliarize yourself with the product, model, and serial nulnbers
listed on each rating plate. Record theln for flmlre reference on
the last page of this booklet.
IMPORTANT FACTS
To better protect your investlnent and to elilninate unnecessary
service calls, fhmiliarize yourself with the following facts:
• Your air conditioning system should never be operated without
a clean air filter properly installed. Plan to inspect the filter peri-
odically. A clogged air filter will increase operating costs and
shorten the life of the unit.
• Supply-air and return-air registers should not be blocked.
Drapes, filrnimre, and toys are some of the items COlrnnonly
found obstructing registers. Restricted airflow lessens the unit's
efficiency and life span.
• The outdoor unit lnust have unrestricted airflow. Do not cover
the unit, lean anything against it, or stand on it. Do not allow grass
clippings, leaves, or other debris to acculnulate around or on top
of the unit. Maintain a 12-in. lninilmun clearance between the
outdoor unit and tall grass, vines, slmlbs, etc.
• Your lnultipurpose indoor therlnostat is the control center for
your air conditioning system. You should falniliarize yourself
with its proper operation. Attelnpting to control the system by
other mean_for instance, switching the electrical supply power
ON and OFF may cause damage to the unit.
• Therlnostat "jiggling" causes rapid-cycling, which is poten-
tially dalnaging to the COlnpressor. Do not lnove the telnperamre
selector on the therlnostat for any reason for at least 5 lninutes
after the colnpressor has shut off'.
• You may find that you can lnaintain greater personal colnfort
by rulming the Pancontinuously. Air pockets can forln due to the
structure of the house, placelnent of registers, etc. These
pockets may be too cool or warm for your lilting. Continuous l:an
operation lninilnizes any telnperamre differences. Also, systems
equipped with electronic or mechanical air cleaners and!or
hulnidifiers offer the added benefits o fhaving the air continuously
cleaned year-round and hulnidified during the winter season.
• A system equipped with a heat or energy recovery ventilator
offers the advantage of exhausting stale air froln the holne and
allowing fresh air in fi%_lnthe outdoors while lninilnizing heat
lOSS.
