All coils have single refrigerant distributors unless noted as below:
^These selections require two circuits. ^^ These selections require three circuits. * These selections require four circuits.
**To estimate performance of coils at other than 10 FPI or at other air speeds or with other refrigerant or air temperatures see page 21, or call your representative. With your representative, you can have specific computer selected coils rated for your job conditions.
