Some of the combinations shown in the above System Charge table require Advanced Main Air Circulating Fan indoor product. For approved coil only matches, please see the “COOLING CAPACITY - Upflow, Downflow & Horizontal Furnaces and Coils” table.
FOOTNOTES:
1.For applications requiring a TXV use
2.Approved orifice(s) shipped with outdoor unit.
3.Systems matched with furnaces or air handlers not equipped with
4.PC coils cannot be used in downflow or horizontal applications. FC coils cannot be used in horizontal applications.
5.Refer to Cooling and Heating Performance Data tables for actual performance for specified system matches.
PROCEDURES:
1.Unit factory charge listed on the unit nameplate includes refrigerant for the outdoor unit, the smallest matched indoor unit, and 15 feet of interconnecting line tubing.
2.Verify the TXV or orifice and additional charge required for specific matched indoor unit in the system using the above table.
3.Add additional charge for the amount of interconnecting line tubing greater than 15 feet at the rate specified in Physical and Electrical Data Table.
4.For indoor matches requiring additional charge, the refrigerant needs to be weighed in for specific matched indoor unit and lineset length.
5.Permanently mark the unit nameplate with the total system charge. Total System Charge = Base Charge (as shipped) + charge adder for matched indoor unit + charge adder for line set.
