Note:
All plumbing connections are made the same way
whether or not the unit has valve packages. Whether
or not you utilize our hose kits and shutoff/balancing
valve all piping connections will have to conform with
all local piping and building codes. The ability to re
-
move the unit in order to perform repairs is imperative.
Note:
Valves, hoses and 90-degree elbows are factory
available accessories, to be field-mounted by others.
Pipe Elbows
90-degree, 1/2" SWT × 1/2" FPT Cast Bronze elbow
fittings can be ordered to make sweat connections to the
unit supply and return pipe stubs to accept the threaded
connection of flexible hoses.

Condensate Hose Connection
Each unit is supplied with a 3/4" (19mm) I.D. clear vinyl
condensate hose internally trapped within the chassis.
The hose extends 14" (356mm) out of the chassis within
the piping compartment to reach the floor or the back
wall.
Field condensate piping must enter within the confines of
the cabinet (back wall or floor) similar to the supply and
return piping. Slide the vinyl hose over the condensate
pipe and clamp it.
