Some of the combinations shown in this table require Advanced Main Air Circulating Fan indoor product. For approved coil only matches, see the
COOLING CAPACITY - Upflow, Downflow, and Horizontal Furnaces and Coils (Coil Only Ratings) table.
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 60 second time delay.
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 the performance data tables for actual performance for specified
system matches. Obtain certified system ratings from www.ahridirectory.org.
CHARGING PROCEDURES
1. 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 feet of
interconnecting lineset.
2. Verify the indoor metering device and additional charge required for the specific matched indoor unit in the system using the above table.
3. Add additional charge for the amount of interconnecting lineset greater than 15 feet at the rate specified in the PHYSICAL AND ELECTRICAL DATA table.
4. For installations requiring additional charge, weigh in refrigerant for the specific matching indoor unit and actual lineset length.
5. Once the charge adders for matched indoor unit and for lineset have been weighed in, verify the system operation against the temperatures and pressures in the
Charging Chart for the outdoor unit. Locate Charging Charts on the outdoor unit and also in the Service Data Application Guide on
www.simplygettingthejobdone.com. Follow the Subcool or the Superheat charging procedure in the Installation Manual according to the type of indoor metering
device in the system, and allow ten minutes after each charge adjustment for the system operation to stabilize. Record the charge adjustment made to match the
Charging Chart.
6. Permanently stamp the unit data plate 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 lineset length + charge adjustments to match the Charging Chart.
