DESCRIPTION
The TH4 models are the newest offering in our successful LX
Series split system heat pump lineup. These outdoor units are
optimized for the new 14 SEER / 8.2 HSPF Minimum Efficiency
in all US Regions, and are specifically designed to be matched
with Coleman 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. Options are provided for
indoor piston or TXV. The factory installed filter-drier and fac-
tory charge for a 15-Ft lineset means less time spent brazing
and charging the system. The small base dimension and
reduced unit size 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 stamped 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 - Air is blown up, away from the structure
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 75 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.
