Notes:
1.
All coils have same end supply and return connections.
2.
Steam coils have a factory installed pressure equalizing valve and a 24ʺ
(610mm) long pressure equalizing line which terminates in a 1⁄2ʺ M.P.T. fitting.
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 Daikin controls.)
4.
Cooling condensate drain pan is shipped sloped down towards the cooling
coil connections but is field reversible.
5.
Electric heating coil power connections are right end only. Junction box has
1ʺ(25mm) and 2ʺ (51mm) (trade size) knockouts, 10-1⁄2ʺ (267mm) from right
end of the unit.
6.
Coil stubs are 7⁄8ʺ I.D. (female) and terminate 9ʺ (229mm) from the end of
the unit.
7.
Steam coils are 1-1⁄8ʺ female (sweat) connections and terminate 9ʺ (229mm)
from the end of the unit.
8.
DX coils (G) have O.D. sweat connections. Interconnecting tube by others.
See
Table 5
for correct tubing size.
