Note: Some of the combinations shown in this table require advanced main air circulating fan indoor product. For approved coil only matches, refer
to the COOLING CAPACITY - Upflow, Downflow, and Horizontal Furnaces and Coils (Coil Only Ratings) table in the Technical Guide.
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..
4. Do not user CF coils in horizontal applications.
5. Charge adders shown above do not indicate that coils are rated for every application. Refer to the performance data tables in the Technical Guide for actual per-
formance for specified system matches. Obtain certified system ratings from
CHARGING
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 ft of inter-
connecting refrigeration piping.
2. Verify the indoor metering device and additional charge required for the specific matched indoor unit in the system using the table above.
3. Add additional charge for the amount of interconnecting refrigeration piping greater than 15 ft 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 refrigeration piping length.
5. 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 also in the Service Data Application Guide on
done.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.
6. 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.
