DESCRIPTION
The TW4B models are the newest addition to our successful LX
Series split system air conditioner lineup. Optimized for the new
14 SEER Regional Minimum Efficiency and the high EER
required in the Southwest US, these outdoor units are specifi-
cally designed to be matched with Johnson Controls Unitary
Products indoor coils, furnaces, and air handlers to provide a
complete system solution.
FEATURES
• Small Footprint - Minimum footprint for easier handling,
transportation, and installation.
• 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. Titanium colored powdercoat paint further protects
external panels.
• Quality Coils - The high efficiency microchannel aluminum
coil is manufactured using an improved material system pro-
viding reliable performance and small unit size.
• 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.
