FOOTNOTES:
1. Systems matched with furnace or air handlers not equipped with blower-off delays may require blower Time Delay Kit 2FD06700224.
2. PC coils cannot be used in downflow or horizontal applications. FC coils cannot be used in horizontal applications.
3. A TXV kit must be used with these coils to obtain system performance. Note: If a TXV is factory installed on the coil, it must be replaced with
the listed TXV
4. Refer to Technical Guide for actual system performance for specified matches.
PROCEDURES:
1. Unit factory charge listed on the unit nameplate includes refrigerant for the condenser, the smallest evaporator and 15 feet of intercon-
necting line tubing.
2. Verify the TXV or orifice and additional charge required for specific evaporator coil 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 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 evap-
orator + adder for line set.
If the F*FP Air Handler used has a with a factory installed R-22 TXV it MUST BE CHANGED OUT to a R-410A TXV or a orifice for proper operation.
If the TXV is not changed out system damage will occur.
