Johnson Controls Ducted Systems 5

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 interconnecting 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 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.

6. For downflow and horizontal-right installations, some indoor units require additional charging adjustments to ensure proper equipment opera-

tion. Refer to the outdoor unit Installation Manual.

7. 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.

Note: Some of the combinations shown in this table require advanced main air-circulating fan indoor products. For approved coil-only matches, see

the SYSTEM CAPACITY - With High Efficiency Motor Furnaces table.

1. For applications that require a TXV, use S1-1TVM*** series kit.

2. Use a TXV kit 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 use XAF or XAU coils in horizontal applications. Do not use XAH coils in upflow or downflow applications.

5. Charge adders shown above do not indicate that coils are rated for every application. See the Performance Data tables for actual performance for specified system

matches. Obtain certified system ratings from
