Installation – Water Line

To produce steam, the dryer must connect to the cold water supply. Since the
washer must also connect to the cold water, a “Y”

connector is inserted to

allow both inlet hoses to make that connection at the same time.

NOTE:

Use the new inlet hoses & “Y”

connector provided; never use old

hoses. (Hose kit -

Long & short hoses, washers & “Y”

connector -

WE25M53)
