Mounting
Steam coils must be properly mounted for condensate removal. This will aid in prevent-
ing destructive water-hammer, keeping coils from freezing and preventing corrosive
elements from collecting in the tubes. Case-pitched coils should be installed level as
shown in Figure 1a. Heatcraft models SA, SB, HA, JA, GA, DA, LA, RA and TA come
standard pitched in the casing. Heatcraft models SS and SH utilize return bend construc-
tion and are not pitched in the casing, but need to be installed level as in Figure 1a - Case
Pitched. Coils that are unpitched, must be installed with the tubes pitched towards the
return connection as shown in Figure 1b (with the exception of Heatcraft models SS and
SH). A minimum pitch of 1/8” per foot of coil length is required (pitch has been exag-
gerated in Figure 1b - Case Unpitched).
