RSAU0062F1

Multiple coils need to be manifolded together in order to
connect with a single water connection. The unit is
supplied with manifolds for both the hot and cold water
coils. Due to shipping restrictions, these manifolds ship
loose in the discharge section of the unit and must be field
installed. Due to variances in header locations, the cooling
coil manifolds are not interchangeable. Each is labeled
with (2) four letter codes. The first four letters (F1AO, for
example) correspond to the last four letter of the AHU's
identifying stencil. The second set of four letters
designates where the piece should be installed on that unit
(i.e. TLFT indicates it should be installed in the upper left
position). The labels are painted onto each pipe in the
cooling coil manifolds. See
