Carrier 42 SERIES - Manual (Page 16)

VALVE PACKAGES
General — Table 1 lists acceptable pneumatic valves for
installation on 42 series fan coil units. There are limitations
on physical size of pneumatic valves, quantity and type of
matching components, required control interface. See Fig. 1
for symbols and placement of valves.
Consult factory before ordering any special valve pack-
age components that are not covered in this book.
Valve packages are shipped with the units or in unit car-
tons. Valve packages include belled ends for field soldering
to coil connections.
All factory-furnished cooling valve packages are ar-
ranged to position as much of the package as possible over
an auxiliary drain pan or drip lip. This helps minimize field
piping insulation requirements.
