1.For applications requiring a TXV use 1TVM series kit.
2.Systems matched with furnace or air handlers not equipped with
3.PC coils cannot be used in downflow or horizontal applications. FC coils cannot be used in horizontal applications.
PROCEDURES:
1.Unit factory charge listed on the unit nameplate includes refrigerant for the condenser, the smallest evaporator and 15 feet of interconnecting line tubing.
2.Verify the TXV and additional charge required for specific evaporator coil in the system using the above table.
3.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 TXV matches requiring additional charge, the refrigerant needs to be weighed in for specific coil match and lineset length.
5.Permanently mark the unit nameplate with the total system charge. Total System Charge = Base Charge (as shipped) + adder for evaporator + adder for line set.
