DESCRIPTION

The LX Residential Series YFK two-stage air conditioners are
the outdoor section of a high efficiency cooling system. They
are designed to be custom matched with one of our complete
line of indoor sections. Matching air handlers are available for
upflow, downflow and horizontal left or right applications to pro-
vide a complete system. Alternately, add-on coils are available
for use with modular air handlers or gas furnaces. Electric heat-
ers and field installed accessories are also available as needed.

FEATURES

• Superior Coil Protection – An easily removable two-piece
steel extruded louver coil guard protects the tube-in-fin coil
from debris and physical damage while making access for
coil cleaning quick and simple.
• Environmentally Friendly Refrigerant – The next genera-
tion refrigerant R-410A delivers environmentally friendly per-
formance with zero ozone depletion.
• Durable Finish – A high quality powder paint finish rated at
1000 hrs. salt spray provides the ultimate protection from
corrosion and harmful UV rays, ensuring a long-lasting, high
quality appearance.
• ECM Fan Motor – Dynamically adjusts speed in sync with
the compressor stage to keep heat exchange in balance
while minimizing power consumption and sound.
• Swept Wing Fan – A design adapted from aerospace engi-
neering provides whisper-quiet operation by allowing air to
flow smoothly and efficiently across the fan surface and
edges.
• High-Efficiency Outdoor Coil – An aluminum fin and cop-
per tube outdoor coil provide easy cleaning, low restriction to
airflow and efficient heat exchange.
• Factory Installed Filter Drier – The liquid line filter drier
removes debris and moisture which can be harmful to the
system.
• Easy Service Access – A large electrical box cover and a
swing open electrical box provide superior full corner access
to the inside of the unit for maintenance or service.
• TXV Controls – All indoor coils utilize TXVs (Thermostatic
Expansion Valves).
• Conventionally Controlled – Designed to operate as a con-
ventionally wired system for easy installation and reliable
operation.
• Two Speed, Protected Scroll Compressor – The compres-
sor is solenoid operated for 67% and 100% capacity. A suc-
tion accumulator tank protects the compressor from
harm.(found on 3, 4 & 5 ton models).
• Agency Listed – Safety certified by CSA to UL 1995 / CSA
22.2. Performance certified to ANSI/AHRI Standard 210/240
