Stainless Steel Care and Cleaning
To prevent discoloration of rust on stainless steel several important
steps need to be taken. First, we need to understand the properties of
stainless steel. Stainless steel contains 70- 80% iron, which will rust.
It also contains 12-30% chromium, which forms an invisible passive
film over the steels surface, which acts as a shield against corrosion.
As long as the protective layer is intact, the metal is still stainless.
If the film is broken or contaminated, outside elements can begin to
breakdown the steel and begin to form rust of discoloration. Proper
cleaning of stainless steel requires soft cloths or plastic scouring pads.
NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!
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.
Cleaning the Condenser Coil
The condenser coil requires regular cleaning, recommended is every
90 days. In some instances though you may find that there is a large
amount of debris and dust or grease accumulated prior to the 90-
day time frame. In these cases the condenser coil should be cleaned
every 30 days. If the build up on the coil consists of only light dust
and debris the condenser coil can be cleaned with a simple brush,
heavier dust build up may require a vacuum or even compressed air to
blow through the condenser coil. If heavy grease is present there are
de-greasing agents available for refrigeration use and specifically for
Care and Cleaning
Drawer Gaskets and Slides
See page 14 for drawer assembly drawing.
Drawer gaskets should be cleaned as required to maintain their ability to
seal properly. Do not use sharp tools or knives to scrape the bellows as this
may tear the gasket and eliminate its ability to seal. A soft bristle brush and
solution of soap and water should be all that is required to keep the gaskets
clean. Do not use full strength degreasing agents on the gasket because
they could cause the gasket to become brittle and crack.
The stainless steel drawer system including the drawer boxes, intermedi-
ate tracks and exterior tracks should be kept free of food and debris. The
intermediate tracks (the track containing all the rollers) are designed to be
removable without tools and are dishwasher safe. They can also be cleaned
in a sink with detergents and a soft bristle brush. The drawer box which
includes the stainless steel front and gasket are also removable without
tools and should be wiped clean of food and debris. Tracks and drawer
boxes should be cleaned on a daily basis for optimum performance.
Preventing Blower Coil Corrosion
To help prevent corrosion of the blower coil, store all acidic items, such as
peppers and tomatoes, in sealable containers. Immediately wipe up all spills of
items.
Thermometer
Part # 3516059
Thermometer Control Switch
To calibrate control or switch from °F to °C follow these steps.
Remove two screws and rear cover plate from thermometer.
Reposition °F/°C switch to desired setting. Insert probe into an
ice water bath. Ensure ice water temp is at 32°F or 0°C. Adjust
calibration screw to proper display temperature. Reinstall rear
cover and screws.
the condenser coils. The condenser coil may require a spray with the
degreasing agent and then blown through with compressed air. Failure
to maintain a clean condenser coil can initially cause high temperatures
and excessive run times, continuous operation with dirty or clogged
condenser coils can result in compressor failures. Neglecting the
condenser coil cleaning procedures will void any warranties associated
with the compressor or cost to replace the compressor.
Never use a high-pressure water wash for this
cleaning procedure as water can damage the electrical
components located near or at 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 at least every three months.
If conditions are such that the condenser is totally blocked in three
months, 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.
