DESCRIPTION
The YFE models are a new offering in our successful LX Series
split system air conditioner lineup. These units are optimized for
the new 14 SEER Regional Minimum Efficiency in the South-
east US, and feature a tube-in-fin condenser coil, scroll com-
pressor, and copper filter-drier. These outdoor units have been
specifically designed to be matched with Johnson Controls Uni-
tary Products indoor coils, furnaces, and air handlers to provide
a complete system solution.
FEATURES
• Quality Coils - Enhanced aluminum fins are mechanically
bonded to copper tubing.
• Scroll Compressor - Featuring the newest generation of
high efficiency scroll compressors.
• Copper filter-drier - The factory installed filter drier features
copper construction for reliable long term protection.
• Easier Installation - Independent panels provide quick
access for unit setup. Installation time is reduced by easy
power and control wiring access. Select indoor matches with
factory-mounted TXVs are available for quicker system
installation. The factory installed filter-drier and factory
charge for a 15-Ft lineset means less time spent brazing and
charging the system. The small base dimension and reduced
unit clearances make for easier retrofits.
• Accessible Information - QR code on unit provides quick
access to technical documents and warranty information.
• Durable Finish - The coated steel wire fan guard, coated
external fasteners, and pre-treated G90-equivalent galva-
nized steel chassis components resist corrosion and rust
creep. Champagne colored powdercoat paint further protects
external panels.
• Rugged Coil Protection - Coils are protected from mechan-
ical damage by a proven stamped steel coil guard design.
• Protected Compressor - Compressors are protected inter-
nally by a high pressure relief valve and a temperature sen-
sor, and externally by the system high pressure switch. The
liquid line filter-drier is factory installed to protect the com-
pressor against moisture and debris.
• Reliable Operation - Ball bearing fan motors provide supe-
rior performance in extreme temperatures.
• Environmentally Friendly - CFC-free R-410A refrigerant
delivers environmentally friendly performance with zero
ozone depletion.
• Top Discharge - Warm air is blown up, away from the struc-
ture and any landscaping and allows compact location on
multi-unit applications.
• Low Operating Sound Levels - Developed using CFD and
FEA tools, the sturdy cabinet and top design provides sound
performance of 76 dBA or lower. Compatible accessories for
further sound reduction are also available.
• Better Service Access - Diagonal base valves with open
access for low-loss fittings, single panel access to the electri-
cal controls, swing out control box for full corner access, and
removable fan guard allow easy access for unit mainte-
nance.
• Agency Listed - Safety certified by CSA to UL 1995 / CSA
22.2. Performance certified to ANSI/AHRI Standard 210/240
in accordance with the Unitary Small Equipment certification
program.
