MAINTENANCE
Cleaning solutions need to be alkaline based or non-chloride cleaners. Any cleaner containing chlorides will
damage the protective film of the stainless steel. Chlorides are also commonly found in hard water, salts, and
household and industrial cleaners. If cleaners containing chlorides are used be sure to rinse repeatedly and dry
thoroughly upon completion.
Routine cleaning of stainless steel can be done with soap and water. Extreme stains or grease should be
cleaned with a non-abrasive cleaner and plastic scrub pad. It is always good to rub with the grain of the steel.
There are also stainless steel cleaners available which can restore and preserve the finish of the steels
protective layer.
Early signs of stainless steel breakdown can consist of small pits and cracks. If this has begun, clean
thoroughly and start to apply stainless steel cleaners in attempt to restore the passivity of the steel.
Never use an acid based cleaning solution！Many food products have an
acidic content which can deteriorate the finish. Be sure to clean the stainless
steel surfaces of ALL food products. Common items include tomatoes,
peppers and other vegetables.
Gasket Maintenance
Gaskets require regular cleaning to prevent mold and mildew build up and also to keep 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 prevent proper seals. Also, never use
sharp tools or knives to scrape or clean the gasket which could possibly tear the gasket and rip the bellows.
Gaskets can easily be replaced and donot require the use of tools or authorized service persons. The gaskets
are "Dart" style and can be pulled out of the grove in the door and new gaskets can be "pressed" back into
place.
Doors/Hinges
Over time and with heavy use doors the hinges may become loose. If it is noticed that the door is
beginning to sag, it may become necessary to tighten the screws that mount the hinge brackets to the
frame of the unit. If the doors are loose or sagging this can cause the hinge to pull out of the frame which
may damage both the doors and the door hinges. In some cases this can require qualified service agents
or maintenance personnel.
Drain Maintenance
Each unit has a drain located inside the unit which removes the condensation from the evaporator coil and
evaporates it at an external condensate evaporator pan. Each drain can become loose or disconnected from
moving or bumping the drain. If you notice excessive water accumulation on the inside of the unit, be sure the
drain tube is connected from the evaporator housing to the condensate evaporator drain pan. If water is
collected underneath the unit you may want to check the condensate evaporator drain tube to be sure it is still
located inside the drain pan. The leveling of the unit is important as the units are designed to drain properly
when on a level surface, if your floor is not level this can also cause drain problems. Be sure all drain lines are
free of obstructions typically food product is found blocking drain lines causing water to back up and overflow
the drain pans.
