CHARGING 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 indoor metering device 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 greater 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 actual lineset length.
5. Once lineset and coil adders have been applied, system operation will need to be matched to the temperatures and pressures noted on the Charging Chart for the
given outdoor and indoor conditions. Charging Charts can be found on the outdoor unit or in the Service Data Application Guide on www.upgnet.com. Subcool or
Superheat charging procedures are determined by the type of indoor metering device. These charging procedures can be found in the Installation Manual included
with outdoor unit.
6. 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 actual lineset charge adjustments to match Charging Chart.

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 requiring 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. CF coils cannot be used in horizontal applications.
5. Charge adders shown above do not indicate that coils are rated for every application. Refer to Performance Data Tables for actual performance for specified sys-
tem matches. Obtain certified system ratings from www.ahridirectory.org.
