Ifextremely dirty, a commercially available condenser cleaner maybe required.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 steels surface whichacts as a shield against corrosion. As long as the protectivelayer is intact, the metal is still stainless. If the film is brokenor contaminated, outside elements can begin to breakdown thesteel and begin to form rust of discoloration.Proper cleaning of stainless steel requires soft cloths or plasticscouring 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 upon completion.Routine cleaning of stainless steel can be done with soap andwater. Extreme stains or grease should be cleaned with a non-abrasive cleaner and plastic scrub pad. It is always good torub with the grain of the steel. There are also stainless steelcleaners available which can restore and preserve the finish ofthe steels protective layer.Early signs of stainless steel breakdown can consist of smallpits and cracks. If this has begun, clean thoroughly and start toapply stainless steel cleaners in attempt to restore the passivityof the steel.Never use an acid based cleaning solution!Many food products have an acidic content whichcan deteriorate the finish. Be sure to clean thestainless steel surfaces of ALL food products.Common items include, tomatoes, peppers andother vegetables.Gasket MaintenanceGaskets require regular cleaning to prevent mold and mildewbuild up and also to keep the elasticity of the gasket. Gasketcleaning can be done with the use of warm soapy water. Avoidfull strength cleaning products on gaskets as this can causethem to become brittle and prevent proper seals. Also, neveruse sharp tools or knives to scrape or clean the gasket whichcould possibly tear the gasket and rip the bellows.Gaskets can easily be replaced and do not require the use oftools or authorized service persons. The gaskets are “Dart”style and can be pulled out of the grove in the door and newgaskets can be “pressed” back into place.Doors/HingesOver time and with heavy use doors the hinges may becomeloose. If it is noticed that the door is beginning to sag, it maybecome necessary to tighten the screws that mount the hingebrackets to the frame of the unit. If the doors are loose orsagging this can cause the hinge to pull out of the frame whichmay damage both the doors and the door hinges. In somecases this can require qualified service agents or maintenancepersonnel.Drain MaintenanceEach unit has a drain located inside the unit which removes thecondensation from the evaporator coil and evaporates it at anexternal condensate evaporator pan. Each drain can becomeloose or disconnected from moving or bumping the drain. If younotice excessive water accumulation on the inside of the unit besure the drain tube is connected from the evaporator housingto the condensate evaporator drain pan. If water is collectedunderneath the unit you may want to check the condensateevaporator drain tube to be sure it is still located inside thedrain pan. The leveling of the unit is important as the units aredesigned to drain properly when on a level surface, if your flooris not level this can also cause drain problems. Be sure all drainlines are free of obstructions, typically food product is foundblocking drain lines causing water to back up and overflow thedrain pans.Fluorescent Light Bulb ReplacementDelfield recommends that fluorescent light bulbs be recycledrather than disposed of.
