4 Johnson Controls Unitary Products

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 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.upgnet.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.
