DESCRIPTION

The TH6B models are part of our successful LX Series split sys-
tem heat pump lineup. These outdoor units are optimized for
the new 16 SEER / 9.0 HSPF Minimum Efficiency in all US
Regions, and are specifically designed to be matched with resi-
dential indoor coils, furnaces, and air handlers to provide a
complete system solution.

FEATURES

• Easier Installation - Independent panels provide quick
access for unit setup. Installation time is reduced by easy
power and control wiring access. All models utilize TXV's.
The factory installed stainless steel 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.
• Rugged Coil Protection - Coils are protected from mechan-
ical damage by a proven extruded louver steel coil guard
design.
• Quality Coils - Enhanced aluminum fins are mechanically
bonded to copper tubing.
• Protected Compressor - Compressors are protected inter-
nally by a high pressure relief valve and a temperature sen-
sor, and externally by the system high and low pressure
switches. The liquid line filter-drier is factory installed to pro-
tect the compressor against moisture and debris.
• Reliable Operation - Ball bearing fan motors provide supe-
rior performance in extreme temperatures. Factory installed
accumulator ensures proper functioning across a wide range
of conditions.
• 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 72 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, full corner access, and removable fan guard
allow easy access for unit maintenance.
• 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.
