FOOTNOTES:
1. For applications requiring a TXV use 1TVM series kit.
2. Approved orifice shipped with outdoor unit.
3. Systems matched with furnace or air handlers not equipped with blower-off delays may require blower Time Delay Kit
2FD06700224.
4. 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 inter-
connecting line tubing.
2. Verify the TXV or orifice 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 match charge weight needs to be weighed in for specififc 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.
Models 12-48 require start kits for TXV matches. Models with "H" on the end of the model number have factory installed start kits.
For models without an "H" refer to tech guide for kit number reference.
F*FP Air Handlers come with a factory installed R-22 TXV. Please note that some models may take a different TXV then what is factory
installed. The proper TXV must be installed for system reliability and performance. Also note, TXV must be removed for orifice match.
