CAUTION: In all steam coil installations, the con-
densate return connections must be at the low point of
the coil to ensure condensate flows freely from the coil
at all times. Failure to do so may cause physical coil
damage from water hammer, unequal thermal stresses,
freeze-up and/or corrosion.
Figure 7. Steam coil header ports. The center port is the supply
connection. The return port is below the supply. The top port
must be closed off.
