Optional Drip Tray Drain

A separate drain tube (not supplied) may be attached to fitting in the bottom of the tray, if desired. Note: Drill a ¼” hole in the center of the fitting, before attaching the drain hose. Direct the other end of this hose into a permanent drain.

Alternate Evaporator Drain

For locations where the Drip Tray is not desired, connect a separate drain hose (not supplied) to the Evaporator Drain Fitting and direct the other end of this hose into a permanent drain.

CAUTION: FAILURE TO INSTALL THE DRIP TRAY OR ALTERNATE EVAPORATOR DRAIN WILL RESULT IN WATER DRIPPING ON TO THE COUNTER AND/OR FLOOR UNDER THE DISPENSER.
