SERVICE AND INSTALLATION MANUAL

Cleaning solutions need to be alkaline based or non-chloride cleaners. Any cleaner containing
chlorides will damage the protective lm 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 nish
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 nish. 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 do not 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 qualied
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
oor 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 overow the
drain pans.
