FOOTNOTES:
1 Only the TXV kits listed above are approved for use in these systems. The charge adder is the same as that listed for the orifice.
2 Models with reciprocating compressors require start kits when matched to TXV indoor coils.
3 Systems matched with furnaces or air handlers not equipped with blower-off delays may require blower Time Delay Kit
2FD06700224.
4 These orifices or TXVs are factory mounted in the flow device of each indoor coil (701, 702, 703 indicates 1TV07...series). A "T"
suffix indicates a coil or air handler with a factory mounted TXV.
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 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 on the previous page.
4. Permanently mark the unit nameplate with the total system charge. Total System Charge = Base Charge (as shipped) + adder for
evaporator + adder for line set.
