7. Once positioned and leveled, permanently
secure the kettle's flanged feet to the floor using 5/16 inch stainless steel lag bolts and floor anchors (supplied by the installer). Secure each of the flanged feet with one bolt in each hole.
8. Connect piping as described in the "PIPING
CONNECTION" section.
ELECTRICAL SERVICE CONNECTIONS
Install in accordance with local codes and/or the National Electric Code ANSI/NFPA No 70-1981 (USA) or the Canadian Electric Code CSA Standard C22.1 (Canada). A separate fused disconnect switch must be supplied and installed. The kettle must be electrically grounded by the installer.
The electric supply must match the power requirements specified on the kettle's rating plate. The copper wiring must be adequate to carry the required current at the rated voltage. Refer to the specification sheet for electrical specifications.
1. Ensure main power is turned off before
connecting wires.
2. Remove the screws at the rear of the center
console cover, and remove the cover. A wiring diagram is affixed to the underside of the console cover.
3. Feed permanent copper wiring 18" through the
cut-out in the bottom of the console. Connect wiring in junction box in the bottom of the console.
4. Turn main power back on.
5. Check for correct rotation of electric motor
(access by removing top front cover on center console). If rotation is incorrect, disconnect main power and reverse any two of the three live lines.
6. Replace the console cover and secure it with
screws.
COMPRESSED AIR CONNECTION
Mixer Kettles with an air activated discharge valve require a minimum of 90 PSI to operate correctly.
If the unit is also supplying air to a Metering Filling Station then a pressure of 100 PSI at a minimum volume of 25 CFM is required.
The air supplied to the mixer should be clean and dry. No oil should be added to the supply air. We recommend the compressed air system be equipped with a drier, filter, and automatic water dump on the air compressor receiver tank. If the distance between the tank and the unit is less than 100 feet then a minimum line size of 3/4" is required. A distance of 100 to 300 feet requires a minimum 1" line.
PIPING CONNECTIONS
1. All plumbing to and from the kettle should be
thoroughly cleaned and inspected for dirt and debris before the final connections to the kettle are made.
2. Connect all piping according to identification tags on unit.
3. Piping between boiler and kettle should be sloped and a drip condensate trap installed at lowest point.
4. Insulating steam piping is recommended for safety and higher efficiency.
5. To determine the correct steam supply pipe size:
A/ Find the total steam requirement using the
first chart.
B/
Use the steam requirement total in the second
chart to find the correct pipe size.

Operating Suggestions
Cleveland Range Mixer Kettles are simple and safe to operate. The following tips will allow you to maximize the use of your new mixer.
1. To achieve optimum performance on tilting
kettles;
Before applying steam to a cold kettle, open the DRAIN COCK to drain condensate from the kettles jacket. Close drain cock when unit is fully drained.
2.
Allow unit to preheat before addition of product to kettle. However when cooking egg and milk products, the kettle should NOT be preheated, as products of this nature adhere to hot cooking surfaces. These types of foods should be placed in the kettle before heating is begun.
3. An important part of kettle cleaning is to
prevent foods from drying on. For this reason, cleaning should be completed immediately after cooked foods are removed. Refer to the "Care and Cleaning" instructions for detailed kettle washing procedures.
4. If a mixer bridge is equipped with a
temperature probe for a controller or thermometer, the probe must be submerged a minimum of thr
ee inches in the product for
accurate readings.
Safety
1. Close PRODUCT DISCHARGE VALVE before
filling the kettle.
2. When raising or lowering MIXER BRIDGE,
insure FAUCET SPOUT is not in the way of MAIN AGITATOR ARM or damage to spout will result.
3.
As a safety precaution the MIXER SPEED CONTROL must first be turned to zero before unit will start to mix.
4. Always remember, like a cooking pot the
kettles become very hot when cooking. Avoid contact with bare skin.

Contrary to popular belief, stainless steels ARE susceptible to rusting.
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.
Stainless steels are passive metals because they contain other metals, like chromium, nickel and manganese that stabilize the atoms. 400 series stainless steels are called ferritic, 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 and carbon. Austenitic types of stainless are not magnetic, and generally provide greater resistance to corrosion than ferritic types.
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 intact and not broken or contaminated, the metal is passive and stain-less. If the passive film of stainless steel has been broken, equipment starts to corrode. At its end, it rusts.
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
Mechanical abrasion means those things that will scratch a steel surface. Steel pads, wire brushes and scrapers are prime examples.
Water comes out of the faucet in varying degrees of hardness. Depending on what part of the country you live in, you may have hard or soft water. Hard water may leave spots, and when heated leave deposits behind that if left to sit, will break down the passive layer and rust stainless steel. Other deposits from food preparation and service must be properly removed.
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!
Here are a few steps that can help prevent stainless steel rust.
1.
Use the pr
oper tools.
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.
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 containing quaternary salts; it also can attack stainless steel and cause pitting and rusting.
4.
Treat your water
.
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 water treatment, call a treatment specialist.
5.
Keep your food equipment clean.
Use alkaline, alkaline chlorinated or non-chloride cleaners at recommended strength. Clean frequently to avoid build-up of hard, stubborn stains. If you boil water in stainless steel equipment, remember the single most likely cause of damage is chlorides in the water. Heating cleaners that contain chlorides have a similar effect.
6.
Rinse, rinse, rinse.
If chlorinated cleaners are used, rinse and wipe equipment and supplies dry immediately. 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 maintain the stainless steel’s passivity film.
7.
Never use hydrochloric acid (muriatic acid) on stainless steel.
8.
Regularly restore/passivate stainless steel.

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