4 Johnson Controls Ducted Systems

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 ft of

interconnecting lineset.

2. Verify the indoor metering device and additional charge required for the specific matched indoor unit in the system using the SYSTEM CHARGE FOR VARIOUS

MATCHED SYSTEMS table.

3. Add additional charge for the amount of interconnecting lineset tubing 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 lineset length.

5. After weighing in the charge adders for the matched indoor unit and lineset, 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. 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 lineset length + charge adjustments to match the Charging Chart.
