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 oor or the back

wall.

Field condensate piping must enter within the connes of

the cabinet (back wall or oor) similar to the supply and

return piping. Slide the vinyl hose over the condensate

pipe and clamp it.
