DESCRIPTION
The 18 SEER Series unit is the outdoor part of a versatile climate
system. It is designed with a matching indoor coil component
from Johnson Controls Unitary Products. Available for typical
applications this climate system is supported with accessories
and documents to serve specific functions.
FEATURES
• Superior Coil Protection – A stamped decorative metal coil
guard completely protects coil from debris and other large
damaging material while a polymer mesh further protects the
coil against smaller particles.
• Isolated Compressor Compartment – A molded composite
bulkhead isolates the compressor from the rest of the unit
reducing sound and vibration.
• Protected Compressors – Each compressor is protected
against high and low pressure as well as excessive tempera-
ture. This is accomplished by by the simultaneous operation of
a high pressure relief valve and temperature sensors which
protect the compressor if undesirable conditions occur.
• Environmentally Friendly Refrigerant – Next generation
refrigerant R-410A delivers environmentally friendly perfor-
mance, with zero ozone depletion.
• Durable Finish – Automotive quality finish provides the ulti-
mate protection from harmful U.V. rays as well as rust creep
ensuring long-lasting high quality appearance. A powder-paint
topcoat is applied over a baked-on primer, using a galvanized,
zinc coated steel base material. The result is a finish that has
been proven in testing to provide 33% greater durability than
conventional powder-coat finishes.
• Lower Installed Cost – Designed to provide enhanced
installability by featuring a slide-down control compartment
allowing easy access to control components along with angled
service valves to reduce overall installation time and cost.
• Low Operating Sound Levels – A fan design boasting tech-
nology adapted from aeronautic and defense engineering pro-
vides for whisper quiet operation by allowing airflow to flow
smoothly and efficiently across the fan tips.
• Filter-Drier – A factory installed, solid core liquid line filter-
drier filters harmful debris and moisture from the system.
• Easy Service Access – A full end, full service, access panel
with handle makes for easy entry to internal components.
• Long Lasting Operation – Strong and durable composite
base pan provides added strength while resisting rust and cor-
rosion as well as reducing sound and vibration.
TM
• QuietDrive system - The swept-wing fan, composite base
pan, isolated compressor compartment and two-stage com-
pressor are engineered as a system to reduce overall sound to
a mere whisper.
• Complete System Control – All models utilize the exclusive
microprocessor based, on-demand, defrost control system.
This system provides optimal comfort, efficiency, and constant
montoring of the entire system for reliable operation. defrost
cycles occur only when necessary. an adjustable balance point
insures supplemental heat is brought on only when required to
meet the space load, for optimum efficiency and reliability.
• In the event improper operating conditions occur (high temper-
ature and/or high pressure), the unit will automatically shut
down to protect the refrigeration system, and switch to back-up
heat. On-board diagnostic LED's guide the technician to the
source of the problem, and an output signal from the control to
the thermostat will alert the homeowner. The control also fea-
tures non-volatile memory, which preserves trouble codes in
the event of power loss. An anti-short cycle timer extends the
life of the compressor by preventing short-cycling.
• Agency Listed - U.L. and C.U.L. listed - approved for outdoor
application. The unit is certified in accordance with the Unitary
Small Equipment cerification program, which is based on ARI
Standard 210/240.
