Background
Stainless steel does not stain, corrode, or rust as easily
as ordinary steel, but it is not stain or corrosion proof.
Stainless steels can discolor or corrode if not maintained
properly.
Stainless steels differ from ordinary carbon steels by the
amount of chromium present. It is this chromium that
provides an invisible protective ¿ lm on the surface called
chrome-oxide. This protective chrome-oxide ¿ lm on the
surface can be damaged or contaminated, which may
result in discoloration, staining, or corrosion of the base
metal.
Care & Cleaning
Routine cleaning of the stainless steel surfaces will serve
to greatly extend the life of your product by removing
contaminants. This is especially important in coastal areas
which can expose the stainless to severe contaminants
such as halide salts, (sodium chloride).
It is strongly recommended to periodically inspect and
thoroughly clean crevices, weld points, under gaskets,
rivets, bolt heads, and any locations where small amounts
of liquid could collect, become stagnant, and concentrate
contaminates. Additionally, any mounting hardware that is
showing signs of corrosion should be replaced.
Frequency of cleaning will depend upon the installation
location, environmental, and usage conditions.
Choosing a Cleaning Product
The choice of a proper cleaning product is ultimately that
of the consumer, and there are many products from which
to choose. Depending upon the type of cleaning and the
degree of contamination, some products are better than
others.
Typically the most effective and ef¿ cient means for routine
cleaning of most stainless steel products is to give the
surfaces a brisk rubbing with a soft cloth soaked in warm
water and a gentle detergent, or mild mixture of ammonia.
Rubbing should, to the extent possible, follow the polish
lines of the steel, and always insure thorough rinsing after
cleaning.
Although some products are called "stainless steel
cleaners," some may contain abrasives which could
scratch the surface, (compromising the protective chrome-
oxide ¿ lm), and some many contain chlorine bleach which
will dull, tarnish or discolor the surface if not completely
removed.
Start-Up After Long-Term Storage:
1.

4.
If stored outside, it is recommended that the unit again
be thoroughly inspected per the storage instructions
above to address any dirt or debris from the weather
and/or animals/insects.
Connect the unit to electrical power.
Turn unit on and con¿ rm your desired control settings.
Allow 24-hrs for the unit to stabilize before loading
contents.
