18 Maintenance Section 4 INTERIOR CLEANING Not When cleaning interior and exterior of unit, care should be taken to avoid the front power switch and the rear power cord. Keep water and/or cleaning solutions away from these parts. Not Never use a high-pressure water jet for cleaning or hose down or flood interior or exterior of units with water. Do not use power cleaning equipment, steel wool, scrapers or wire brushes on stainless steel or painted surfaces. The interior can be cleaned using soap and warm water. If this isn t sufficient, try ammonia and water or a nonabrasive liquid cleaner. To help prevent corrosion of the evaporator coil, store all acidic items, milk is slightly acidic, in seal-able containers. Immediately wipe up all spills. Cleaning the NLFAC milk dispensers This instruction applies to the model NLFAC dispenser only. A drain is supplied to simplify cleaning of the interior. Open the drain tube clamp. Drain accumulated liquid from the cabinet. Be sure to re-clamp the tubing before resuming operation of the NLFAC unit. After cleaning the interior and exterior as described, be sure to return the milk case loading tray to the bottom of the unit. The load tray is required not only for easy self-locating of milk cases, but it also ensures proper air flow through the evaporator coil for the air curtain. Not Any restriction to the air flow path, including leaving the milk case load tray out of the cabinet, will result in the voiding of your warranties. Self-Contained Units Evaporator Maintenance Each unit has a drain located inside the unit that removes the condensation from the evaporator coil and routes it to an external condensate evaporator pan. Each drain can become loose or disconnected during normal use. If you notice water accumulation on the inside of the unit, be sure the drain tube is connected to the evaporator drain pan. If water is collecting underneath the unit, make sure the end of the drain tube is in the condensate evaporator. The leveling of the unit is important as the units are designed to drain properly when level. Be sure all drain lines are free of obstructions. Remote Units Evaporator Maintenance The stainless steel condensate evaporator pan should be cleaned monthly. Use a vacuum cleaner or damp cloth to remove dust that may have accumulated. This will prevent corrosion of the stainless steel. 18 Part Number: /16

19 Section 4 Maintenance EXTERIOR CLEANING Not Never use an acid based cleaning solution on exterior panels! Many food products have an acidic content, which can deteriorate the finish. Be sure to clean the stainless steel surfaces of ALL food products. Clean the area around the unit as often as necessary to maintain cleanliness and efficient operation. Wipe surfaces with a damp cloth rinsed in water to remove dust and dirt from the outside of the unit. Always rub with the grain of the stainless steel to avoid marring the finish. If a greasy residue persists, use a damp cloth rinsed in a mild dish soap and water solution. Wipe dry with a clean, soft cloth. Never use steel wool or abrasive pads for cleaning. Never use chlorinated, citrus based or abrasive cleaners. Stainless steel exterior panels have a clear coating that is stain resistant and easy to clean. Products containing abrasives will damage the coating and scratch the panels. Daily cleaning may be followed by an application of stainless steel cleaner which will eliminate water spotting and fingerprints. Early signs of stainless steel breakdown are small pits and cracks. If this has begun, clean thoroughly and start to apply stainless steel cleaners in attempt to restore the steel. Gasket Maintenance Gaskets require daily cleaning to prevent mold and mildew build up and also to retain the elasticity of the gasket. Gasket cleaning can be done with the use of warm soapy water. Avoid full strength cleaning products on gaskets as this can cause them to become brittle and crack. Never use sharp tools or knives to scrape or clean the gasket. Gaskets can be easily replaced and do not require the use of tools or an authorized service person. The gaskets are Dart style and can be pulled out of the groove. Soak new gaskets in warm water to make them more pliable. Dry and press back into place. Casters Wipe casters with a damp cloth monthly to prevent corrosion. Defrosting Milk or Ice Cream dispensers require defrosting after 3/8 of frost forms. On/Off switch is located above the louver panel. Never use sharp objects or tools to clean or scrape ice/frost build up from the refrigerated cold pans. A puncture to the pan could cause irreparable damage to the refrigeration system. CLEANING THE CONDENSER COIL In order to maintain proper refrigeration performance, the condenser fins must be cleaned of dust, dirt and grease regularly. It is recommended that this be done monthly. If conditions are such that the condenser is totally blocked in a month, the frequency of cleaning should be increased. Clean the condenser with a vacuum cleaner or stiff brush. If extremely dirty, a commercially available condenser cleaner may be required. Failure to maintain a clean condenser coil can initially cause high temperatures and excessive run times. Continuous operation with a dirty or clogged condenser coil can result in compressor failure.
