Lock drip tray in place by slight downward pressure.
ROUTING UNIT PRODUCT INLET LINES AND DRIP TRAY DRAIN HOSE OUT OF UNIT CABINET NOTE: An alternate arrangement for following installation method described would be to install available 6--inch leg kit (P/N 187416--000) or four caster kit (P/N 316290--000). IMPORTANT: When routing product inlet lines out through side of unit, use care to see that lines do not come in contact with compressor or hot discharge line. Accidental contact may result in foaming of dispensed product. 1.
B. Remove water fill hole plug from evaporator tank cover. 6. Plug unit power cord into a properly grounded electrical outlet. C. Fill evaporator tank until water starts flowing from overflow tube. USE LOW--MINERAL--CONTENT WATER WHERE A LOCAL WATER PROBLEM EXISTS. 7. Flip unit power switch to ‘‘ON’’(up) position. D. Install plug in water fill hole in evaporator tank cover. E. Install plug in end of evaporator tank overflow tube after full ice bank has been formed. 8.

Install evaporator tank cover and coils line fittings, connect agitator motor ground wire and power cord, and connect product inlet lines swivel nut connections to fittings on evaporator tank cover. B.
CLEANING AND SANITIZING 6. If ice bank is dirty, allow it to melt. Hot water may be used to speed melting. DAILY CLEANING OF UNIT CAUTION: Never use an ice pick or other instrument to remove ice from evaporator. Such practice can result in punctured refrigerant circuit or damage to corrosion protective coating on evaporator tank. NOTE: Drip tray that is connected to drain hose routed to waste container or permanent drain need not be removed from unit to be cleaned.
