FOR INSTALLATION IN ALL US REGIONS AND CANADA

Installation Allowed

DESCRIPTION

The TH4 model outdoor units are optimized for the 14 SEER /

8.2 HSPF Minimum Efficiency in all US Regions, and are spe-

cifically designed to be matched with Luxaire indoor coils, fur-

naces, 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. 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 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 stainless steel filter-drier is factory

installed to protect 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.
