V. COIL CONNECTIONS
Figure 5 is a rear view photo of a partially disassem
bled Model 48W-379A unit.
The coil location and chilled water connections for
both the 48W- and 60W-379A are the same for both
units. These two models differ only in the size of the
factory installed chilled water coil.
Two 2-3/8-inch diameter holes are provided in the
right rear corner panel for the chilled water piping en
trance to the unit.
NOTE: Two packaged vinyl grommets are shipped
loose in the blower compartment. Insert one grommet
in each of the 2-3/8-inch corner panel holes.
Route the chilled water piping through the two grom
mets and connect to the two 1-inch F.P.T. connectors
on the coil header. Refer to Figure 5 for chilled water
inlet and outlet connections.
