DESCRIPTION
The 14.5 SEER Series unit is the outdoor part of a versatile climate system. It is designed with a matching indoor coil component from Johnson Controls Unitary Products. Available for
typical applications this climate system is supported with accessories and documents to serve specific functions.
FEATURES
• Small Footprint - Extremely lightweight with a compact footprint, it is a perfect fit for any application.
• Quality Condenser Coils - The coil is construc ted of aluminum microchannel tubing and enhanced aluminum fins for
reduced size and increased efficiency.
• Coil Protection - Coils are protected from damage by a slotted, stamped steel coil guard and secondary polymer mesh.
• Optional Factory E-Coat - Available ElectroFin® coated coil
on select models.
• Protected Compressor - Compressors are protected internally by a high pressure relief valve and a temperature sensor, and externally by the system high pressure switch. A
factory installed liquid line filter-drier further protects the compressor against moisture and debris.
• Environmentally Friendly Refrigerant - The next generation refrigerant R-410A delivers environmentally friendly performance with zero ozone depletion.
• Durable Finish - An automotive quality finish provides the
ultimate protection from harmful UV rays and rust-creep,
ensuring a long-lasting, high quality apprearance . A powder
paint top coat is applied over a baked on primer using a galvanized, zinc coated steel base material.
• Lower Installed Cost - Installation time and costs are
reduced by easy power and control wiring connections. The
unit is factory charged for a 15-foot lineset. The small base
dimension means less space is required on the ground or
roof.
• T op Discharge - Warm air from the top mounted fan is blown
up, away from the structure and any landscaping. This allows
compact location on multi-unit applications.
• Quiet Operation - The compressor sound blanket and the
swept wing fan blade keep sound to a minimum. The upward
air flow carries the normal operating noise away from the living area. The rigid top panel effectively isolates any motor
sound. Isolator mounted compressor and the conde nser coil
muffle the normal fan motor and compressor operating
sounds.
• Low Maintenance - Long life, permanently lubricated motorbearings need no annual servicing.
• Easy Service Access - Fully exposed refrigerant connections and a single panel covering the electrical controls make
for easy servicing of the unit.
• Secured Service Valves - Secured, re-usable service
valves are provided on both the liquid and vapor swe at connections for ease of evacuating and charging.
• 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.

Some of the combinations shown in the above System Charge table require Advanced Main Air Circulating Fan indoor product. For approved coil
only matches, please see the “COOLING CAPACITY - Upflow, Downflow & Horizontal Furnaces and Coils” table.
FOOTNOTES:
1. For applications requ i r i ng a TXV use S1-1TVM*** series kit .
2. A TXV kit must be used with these indoor units to obtain system performance.
3. Systems matched with furnaces or air handlers not equipped with blower-off delays may require blower Time Delay Kit S1-2FD06700224.
4. PC coils cannot be used in downflow or horizontal applications. FC coils cannot be used in horizontal applications.
5. Refer to Cooling Performance Data tables for actual system performance for specified syst em matches.
PROCEDURES:
1. Unit factory charge listed on the unit nameplate includes refrigerant for the outdoor unit, the smallest matched indoor unit, and 15 feet of interconnecting line tubing.
2. Verify the TXV and additional charge required for specific matched indoor unit in the system using the above table.
3. Add additional charge for the amount of interconnecting line tubing great er than 15 feet at the rate specified in Physical and Electrical Data Table.
4. For indoor matches requiring additional charge, the refrigerant needs to be weighed in for specific matched indoor unit and lineset length.
5. Permanently mark the unit nameplate with the total system charge. Total System Charge = Base Charge (as shipped) + charge adder for matched indoor unit +
charge adder for line set.
