* CX34 coils and all air handlers - The factory installed expansion valve must
be replaced with the expansion valve listed (ordered separately).
If the combination is not listed above, the factory installed TXV is used.
Units which do not have an indoor air-circulating blower
furnished as part of the model, i.e., split system with
indoor coil only, is established by subtracting from the
total cooling capacity 1250 Btu/h per 1,000 cfm, and by
adding the same amount to the heating capacity. Total
power input for both heating and cooling is increased by
365 W per 1,000 cfm of indoor air circulated.
