NOTE(S):

a. May be field manifolded for either face split or row split.

b. Where each TXV has the same number of circuits, that number is shown once. When coil has an uneven number of circuits per TXV, both values are shown.

c. Factory-supplied distributors have factory-selected nozzle sizes shown. If necessary, replace factory-supplied nozzles with field-supplied and installed nozzles. Consult

Electronic Catalog AHU selection program for correct nozzle selection.

d. Not available on 39LB units.

AHU — Air-Handling Unit Selection Program

TXV — Thermostatic Expansion Valve (Field-supplied)
