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 filter-drier is shipped loose for
installation in the field. The unit is factory-charged for 15 ft refrigeration piping. 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 galvanized steel chassis components resist corrosion and rust creep.
Champagne colored powdercoat paint further protects external panels.
•Quality coils - The high efficiency microchannel aluminum coil is manufactured using an
improved material system, providing reliable performance and small unit size.
•Rugged coil protection - Coils are protected from mechanical damage by a proven stamped
steel coil guard design.
•Protected compressor - Compressors are protected internally by a high-pressure relief valve
and a temperature sensor, and externally by the system high-pressure switch.
•Reliable operation - Ball bearing fan motors provide superior 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 structure and any landscaping, allowing
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 electrical controls, swing out control box for 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.

Physical and electrical data notes
1. Rated in accordance with AHRI Standard 110-2012, utilization range A.
2. Dual element fuses or HACR circuit breaker. Maximum allowable overcurrent protection.
3. Dual element fuses or HACR circuit breaker. Minimum recommended overcurrent protection.
4. Rotary compressor models are limited to an equivalent length of refrigeration piping of 100 ft
with no exceptions.
5. Refer to the Hard Start Kit Accessory Installation Manual for the hard start kit part number for
each model. The hard start kit is a field installed accessory.
6. For applications with non-standard vapor line sizes, refer to the Applications and accessories
section.
7. The unit charge is correct for the outdoor unit, smallest matched indoor unit, and 15 ft
of refrigerant tubing. For tubing lengths other than 15 ft, add or subtract the amount of
refrigerant, using the difference in actual refrigeration piping length (not the equivalent
length) multiplied by the per foot value.
‡ The adapter fitting must be field installed for the required 1 1/8 in. refrigeration piping.
