Cooling Only
Notes:
1. Linear dimensions referenced from rear of
unit. Right hand views shown, dimensions
are identical for left-hand configurations.
Connection hand is determined by facing
discharge air grille.
2.
R
= Return,
S
= Supply
3. Numerical codes [#] denote optional stain-
less steel drain pan (cooling coils).

Notes:
1.
All coils have the same end supply and return connections.
2.
All water stubs are 7/8" I.D. (female) sweat and all steam coils are

8
" (female) sweat connections. All coil connections terminate 9"
(229mm) from the end of the unit.
3.
Steam coils have a factory installed pressure equalizing valve and
a 24" (610mm) long pressure equalizing line which terminates in a
1/2
" M.P.T. fitting.
4.
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.)
5.
Cooling condensate connection is same end as cooling coil con-
nections, but is field reversible. Drain can be sloped in field.
6.
All dimensions are approximated.
7.
DX coils (G) have female sweat connections. Interconnecting tube
for correct tubing size.
