N8000 Series Drop-In Installation and Operation ManualFor customer service, call (800) 733-8829, (800) 733-8821, Fax (989) 773-3210, www.delfield.com16Delfield™ ®MaintenanceDrain Maintenance - N8100-FA SeriesEach unit has a drain located inside the unit that removesthe condensation from the evaporator coil and routes it to anexternal condensate evaporator pan. Each drain can becomeloose or disconnected during normal use. If you notice wateraccumulation on the inside of the unit be sure the drain tubeis connected to the evaporator drain pan. If water is collectingunderneath the unit make sure the end of the drain tube is inthe condensate evaporator in the machine compartment. Theleveling of the unit is important as the units are designed todrain properly when level. Be sure all drain lines are free ofobstructions.The power switch must be turned to OFF andthe unit disconnected from the power sourcewhenever performing service, maintenancefunctions or cleaning the refrigerated area.Stainless Steel Care and CleaningTo prevent discoloration or rust on stainless steel severalimportant steps need to be taken. First, we need to understandthe properties of stainless steel. Stainless steel contains 70- 80%iron, which will rust. It also contains 12-30% chromium, whichforms an invisible passive film over the steel’s surface, whichacts as a shield against corrosion. As long as the protectivelayer is intact, the metal is still stainless. If the film is broken orcontaminated, outside elements can begin to breakdown thesteel and begin to form discoloration or rust. Proper cleaningof stainless steel requires soft cloths or plastic scouring pads.NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!Cleaning solutions need to be alkaline based or non-chloridecleaners. Any cleaner containing chlorides will damagethe protective film of the stainless steel. Chlorides are alsocommonly found in hard water, salts, and household andindustrial cleaners. If cleaners containing chlorides are used besure to rinse repeatedly and dry thoroughly. Routine cleaningof stainless steel can be done with soap and water. Extremestains or grease should be cleaned with a non-abrasive cleanerand plastic scrub pad. Always rub with the grain of the steel.There are stainless steel cleaners available which can restoreand preserve the finish of the steels protective layer. Early signsof stainless steel breakdown are small pits and cracks. If thishas begun, clean thoroughly and start to apply stainless steelcleaners in attempt to restore the passivity of the steel.CAUTIONNever use an acid based cleaning solution!Many food products have an acidic content,which can deteriorate the finish. Be sure to cleanthe stainless steel surfaces of ALL foodproducts. Common items include, tomatoes,peppers and other vegetables.Cleaning the Condenser CoilIn order to maintain proper refrigeration performance, thecondenser fins must be cleaned of dust, dirt and greaseregularly. It is recommended that this be done at least everythree months. If conditions are such that the condenser is totallyblocked in three months, the frequency of cleaning should beincreased. Clean the condenser with a vacuum cleaner or stiffbrush. If extremely dirty, a commercially available condensercleaner may be required.Failure to maintain a clean condenser coil can initially cause hightemperatures and excessive run times. Continuous operationwith a dirty or clogged condenser coil can result in compressorfailure. Neglecting the condenser coil cleaning procedures willvoid any warranties associated with the compressor and cost toreplace the compressor.CAUTIONNever use a high-pressure water wash for thiscleaning procedure as water can damage theelectrical components located near or at thecondenser coil.
