steel. Other deposits from food preparation and  
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-

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.

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.
