FOOTNOTES:
1. These orifices are packed in the customer packet of each outdoor unit.
2. These orifices are factory mounted in the flow control device of each indoor coil.
3. TXV kit must be used with these coils to obtain system performance. (701,702,703 indicates 1TV07 ...series).
4. Systems matched with furnaces or air handlers not equipped with blower-off delays, may require blower Time Delay Kit #2FD0670224.
PROCEDURES:
1. Unit factory charge listed on the unit nameplate includes refrigerant for the condenser, the smallest evaportor and for 15 feet of intercon-
necting line tubing.
2. Verify the orifice size and additional charge required for specific evaportor 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 the table above.
4. Permanently mark the unit nameplate with the total system charge. Total System Charge = Base Charge (as shipped) + adder for
evaportor + adder for line set.
5. If the orifice in the evaportor was changed, verify the evaportor nameplate has been marked with the correct orifice size.
