Notes:
1. All coils have same end supply and return connections.
2. Steam coils have a factory installed pressure equalizing valve and
a 24" (610mm) long pressure equalizing line which terminates
in a
3. Steam/hot water connections may be same end as cooling
coil connections, but they are recommended to be opposite
end to facilitate piping. (Must be opposite end when using AAF
controls.)
