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 pretreated G90-equivalent galvanized steel chassis components resist corrosion and rust creep.
Champagne colored powder coat 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

Rated in accordance with AHRI Standard 110-2012, utilization range A.
Dual element fuses or HACR circuit breaker. Maximum allowable overcurrent protection.
Dual element fuses or HACR circuit breaker. Minimum recommended overcurrent protection.
Rotary compressor models are limited to an equivalent length of refrigeration piping of 100 ft with no exceptions.
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.
For applications with non-standard vapor line sizes, refer to the Applications and accessories section.
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.

System charge A-coil data notes

For applications requiring a TXV, use S1-1TVM*** series kit.
A TXV kit must be used with these indoor units to obtain system performance.
Systems matched with furnaces or air handlers not equipped with blower-off delays may require blower time delay.
Do not use XAF/XAU coils in horizontal applications. Do not use XAH coils in upflow/downflow applications.
Charge adders shown above do not indicate that coils are rated for every application. Refer to the Performance data tables for actual performance for specified system matches. Obtain certified system ratings from http://www.ahridirectory.org.

Charging

Check the factory unit charge listed on the unit nameplate to verify the refrigerant charge for the outdoor unit, the smallest matched indoor unit, and the 15 ft of interconnecting refrigeration piping.
Verify the indoor metering device and additional charge required for the specific matched indoor unit in the system using Table .
Add additional charge for the amount of interconnecting refrigeration piping greater than 15ft at the rate specified in Table.
For installations requiring additional charge, weigh in refrigerant for the specific matching indoor unit and actual refrigeration piping length.
After weighing in the charge adders for the matched indoor unit and refrigeration piping, verify the system operation against the temperatures and pressures in the charging chart for the outdoor unit. Locate the charging charts on the outdoor unit and in the Service Data Application Guide on www.simplygettingthejobdone.com. Follow the subcool or superheat charging procedure in the Installation Manual according to the type of indoor metering device in the system, and allow 10 min after each charge adjustment for the system operation to stabilize. Record the charge adjustment made to match the charging chart.
Permanently stamp the unit nameplate with the total system charge defined as follows: total system charge = base charge (as shipped) + charge adder for matched indoor unit + charge adder for actual refrigeration piping length + charge adjustments to match the charging chart.

Condenser only performance data notes

For outdoor unit (condenser) performance only. Data does not include the effects of air handler power or heat.
Performance based on 15°F subcooling and 15°F superheat at the outdoor unit base valves:
a. Increase capacity by 1% for each 2°F increase in subcooling.
b. Decrease capacity by 1% for each 2°F decrease in subcooling.
Maximum recommended condensing temperature is 140°F.
