TO INSTALL: Plumbing
Built In, Gravity Drain Model:
The drain and inlet water tubes must be plumbed
before connecting to the ice machine. All horizontal
runs of drain lines must have a 1/4" per foot fall. An
air gap will likely be required between the ice
machine drain tube and the drain/waste
receptacle. A stand pipe with a trap below it would
be acceptable for the drain/waste receptacle.
Note: Poor draining will cause a high rate of
ice melting in the bin.
