Stainless Steel/Surface Care; Air Filtration Care - Perlick CC24B-2 Installation & Operation Manual

Perlick's stainless steel surfaces are food grade,
304 stainless steel. Stainless steel is a "passive"
metal because it contains other metals like
Chromium, Nickel and Manganese that stabilize
the atoms. Chromium provides an invisible film that
covers the steel surface, acting as a shield agent
against corrosion. As long as the film is intact and
not contaminated, the metal is passive and stainless.
If the passive film of stainless steel has been broken,
the surface can start to corrode or rust.
Three materials or processes can break down
stainless steel's passive layer, allowing corrosion
to occur.
▪ Mechanical Abrasion
This refers to items that will scratch stainless
steel surfaces. Steed pads, wire brushes and
scrapers are prime examples.
▪ Water
Water that comes out of the faucet in varying
degrees of hardness. Hard water may leave
spots. When allowed to sit, these deposits will
break down the passive Chromium layer and
rust stainless steel. Other deposits from food
preparation must be promptly removed with an
appropriate cleaning agent.
▪ Chlorides
Chlorides are found everywhere. They are
in water, food and table salt. Household and
industrial cleaners are the worst offenders.
Preventing Stainless Steel Rust
Use non-abrasive tools to clean stainless steel
surfaces. Soft cloths and plastic scouring pads will
not harm the steel's passive layer.
Clean with polish lines. Some stainless steels have
visible polishing lines or "grain". When visible lines
are present, always scrub in a motion parallel to the
lines. When the grain cannot be seen, polish in a
consistent straight pattern - not in a circular motion.
Use alkaline, alkaline chlorinated or non-chloride
containing cleaners. While many traditional cleaners
are loaded with chlorides, the industry is providing

an ever-increasing choice of non-chloride cleaners.
If you are not sure of chloride content in the
cleaner being used, contact your cleaner supplier.
If you present cleaner contains chloride, ask your
supplier for an alternative. Avoid cleaners containing
quaternary salt; it also can attack stainless steel
and cause pitting and/or rusting. Clean frequently to
avoid build-up of hard, stubborn stains.
Stainless Steel Exterior Door Cleaning
Keep exterior stainless steel surface pristine by
wiping the door with a damp microfiber cloth,
followed by a dry polishing chamois. Always follow
the grain direction when cleaning.
Glass Cleaning
Perlick's triple pane glass is designed to protect
cabinet contents from UV light, while displaying
the contents elegantly while the door is closed. To
ensure life long performance, always use standard
glass cleaners containing alcohol to clean the
acid-etched glass. Never use products containing
hydrofluoric acid, fluorine, chlorine or ammonia
derivatives because they can damage the surface
of the glass. Never use acidic and alkaline products
as they can abrade the glass surface.
AIR FILTRATION
We recommended changing the air filters every
6 months for optimum performance. Filters can
be purchased through your local authorized
Perlick dealer.
Carbon Air Filter
The Carbon air filter removes odor, bacteria
and mold spores from the air. To remove the
Carbon air filter in all units, refer to page 29 -
carbon air filter.
