service must be properly removed.
STAINLESS STEEL EQUIPMENT
CARE AND CLEANING
Contrary to popular belief, stainless
steels ARE susceptible to rusting.
Chlorides are found nearly everywhere. They
are in water, food and table salt. One of the
worst chloride perpetrators can come from
household and industrial cleaners. So what
does all this mean? Don’t Despair!
Corrosion on metals is everywhere. It is
recognized quickly on iron and steel as
unsightly yellow/orange rust. Such metals are
called “active” because they actively corrode
in a natural environment when their atoms
combine with oxygen to form rust.
Here are a few steps that can help prevent
stainless steel rust.
1. Use the proper tools.
Stainless steels are passive metals because
they contain other metals, like chromium, nickel
and manganese that stabilize the atoms. 400
seriesstainlesssteelsarecalledferritic,contain
chromium, and are magnetic; 300 series
stainless steels are called austenitic, contain
chromium and nickel; and 200 series stainless,
also austenitic, contains manganese, nitrogen
andcarbon. Austenitictypesofstainlessarenot
magnetic, and generally provide greater
resistance to corrosion than ferritic types.
When cleaning stainless steel products,
use non-abrasive tools. Soft cloths and
plastic scouring pads will not harm steel’s
passive layer. Stainless steel pads also
can be used but the scrubbing motion
must be in the direction of the
manufacturers’ polishing marks.
2. Clean with the polish lines
Some stainless steel comes with 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, play it safe and use a soft cloth or
plastic scouring pad.
With 12-30 percent chromium, an invisible
passive film covers the steel’s surface acting as
a shield against corrosion. As long as the film is
intactandnotbrokenorcontaminated,themetal
is passive and stain-less. If the passive film of
stainless steel has been broken, equipment
starts to corrode. At its end, it rusts.
3. 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 used, contact your
cleaner supplier. If your present cleaner
contains chlorides, ask your supplier if they
have an alternative. Avoid cleaners
containingquaternarysalts;italsocanattack
stainlesssteelandcausepittingandrusting.
Enemies of Stainless Steel
There are three basic things which can break
down stainless steel’s passivity layer and
allow corrosion to occur.
1. Mechanical abrasion
2. Deposits and water
3. Chlorides
4. Treat your water.
Mechanical abrasion means those things
that will scratch a steel surface. Steel pads,
wire brushes and scrapers are prime
examples.
Though this is not always practical,
softening hard water can do much to
reduce deposits. There are certain filters
that can be installed to remove distasteful
and corrosive elements. To insure proper
watertreatment, callatreatmentspecialist.

5. Keep your food equipment clean.
6. Rinse, rinse, rinse.
Use alkaline, alkaline chlorinated or non-
chloridecleanersatrecommendedstrength.
Clean frequently to avoid build-up of hard,
stubbornstains. Ifyouboilwaterinstainless
steel equipment, remember the single most
likely cause of damage is chlorides in the
water.Heatingcleanersthatcontainchlorides
have a similar effect.
If chlorinated cleaners are used, rinse and
wipe equipment and supplies dry immedi-
ately. The sooner you wipe off standing
water, especially when it contains cleaning
agents, the better. After wiping equipment
down, allow it to air dry; oxygen helps main-
tain the stainless steel’s passivity film.
7. Never use hydrochloric acid (muriatic
acid) on stainless steel.
8. Regularly restore/passivate stainless
steel.

1. Stainless steels rust when passivity (film-
shield) breaks down as a result of scrapes,
scratches, deposits and chlorides.
6. Wipe off cleaning agent(s) and standing
water as soon as possible. Prolonged
contact causes eventual problems.
2
Stainless steel rust starts with pits and
cracks.
To learn more about chloride-stress corrosion
and how to prevent it, contact the equipment
manufacturer or cleaning materials supplier.
3. Use the proper tools. Do not use steel
pads, wire brushes or scrapers to clean
stainless steel.
Developed by Packer Engineering, Naperville, Ill., an
independent testing laboratory.
4. Use non-chlorinated cleaners at
recommended concentrations. Use only
chloride- free cleaners.

MAINTENANCE
FILLING THE RESERVOIR JACKET
VENTING
Before adding water to the reservoir, the water
supply should be analyzed to ensure that
hardness is no greater than 2.0 grains per
gallon and the pH level is within the range of
7.0 to 8.5. Water which fails to meet these
standards should be treated, or use ionized
distilled water with sodium. Equipment failure
caused by inadequate water quality is not
covered under warranty. To fill the reservoir
jacket, perform the following:
The vacuum pressure gauge measuring zone
should be between 20 to 30 in.Hg (84 to
100kPa). If the vacuum pressure is not within
this range, perform the following:
1. With the kettle empty, place the power
switch to the ON position.
2. Set the temperature control to the max
heat setting. Let the kettle heat until it
cycles off.
1. Set the thermostat and power switch to
OFF position.
3. Pull the pressure relieve valve D-ring to
relieve pressure for 10 seconds.
4. Turn kettle off and let cool. Check for a
correct vacuum pressure of 20 to 30 in. Hg
(84 to 100kPa). If the reading is not correct,
repeat steps 1 through 3.
2. Release any pressure by the O-ring on the
pressure relief valve. Then remove the 1/2"
plug on the back of the kettle.
3. Insert a funnel into the fill valve and add 3
or 4 ounces of water.
4. Replace and properly tighten the 1/2" plug.
5. Turn on the kettle.
