Installation–––––––––––––––––––––––––––––––––––––––––––––––––––––––––

CAUTION!

No service or maintenance should be performed until the technician has thoroughly read this service manual. Except for routine cleaning and sanitizing, only qualified technicians should attempt to service or maintain this equipment.

1.Measure to verify that the dispenser will fit in the desired location.. A clearance of at least 3" (77 mm) is required behind the dispenser for the electrical and optional drain connection..

2.Ensure that the finished floor inside the cabinet is flush (level) with the floor outside the cabinet (Fig.. 1).. If the cabinet floor is lower than the finished floor, the cabinet floor must be built up (using appropriate materials) until it is flush with the finished floor.. A flush floor is required for proper operation and maintenance/service of the dispenser..

3.Rough-in the electrical service, water line, and optional Drip Tray Drain Kit*..

Note: The dispenser must be installed such that it can be moved forward at least 4" (10..16 cm) to allow access to the Bin Lid Cleaning Spout (Fig.. 9..6) for dispenser cleaning and sanitizing.. Take this requirement into consideration during rough-in..

§§ Electrical: 115V, single phase, 15A receptacle required.. The dispenser has an integral 8 ft.. (2..4 m) cord and plug..

§§ Water: supply line (with shut-off valve) connects to the dispenser's 1/4" MPT inlet..

*The optional Drip Tray Drain Kit (item# 00956375) requires a floor drain within 15 ft.. (4..5 m) of the dispenser.. For detailed installation instructions, please refer to the instructions shipped with the Drip Tray Drain Kit..

4.Install the angle bracket inside the cabinet,18..15" (461 mm) from the toe kick (Fig.. 2..1).. The bracket prevents the dispenser from being located/pushed beyond the recommended cabinet space depth.. Do not attach the bracket to the dispenser..
