MAINTENANCE
Cleaning solutions need to be alkaline based or non-chloride based. Any cleaner containing chlorides will
damage the protective film of the stainless steel. Chlorides are 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.
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.
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. Do not
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 don’t require the use of tools or authorized service technicians. The
gaskets are "Dart" style and can be pulled out of the grove in the door and replaced by pressing the new one
back into place.
Doors/Hinges
Over time and with heavy use, door hinges may become loose. If the door is beginning to sag, 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 to both the doors and the door hinges.
Drain Maintenance
Each unit has a drain located inside the unit which removes the condensation from the evaporator coil and
evaporates it into 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 starts to collect 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 because this may cause water to back up and overflow the drain pans.
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.
