RECOMMENDED PIPING SCHEMATICS
(all service connections shown supplied by others)
Recommended Piping Schematic
STEAM
All steam plumbing to and from the kettle and steam boiler should be thoroughly cleaned and inspected for dirt and debris before final connection to the kettle are made.
Generally, kettles require 1/2" i.p.s. pipe, 10-45 psi steam pressure. If the steam supply pressure exceeds 45 psi, a pressure reducing valve is required. The steam inlet is at the right side of the kettle, as seen from the front.
CONDENSATE
Maximum pressure rating on kettles is 50 psi. It is highly recommended that a pressure relief valve equal to or less than this pressure be installed on the incoming steam line close to the kettle.
A steam condensate trap must be plumbed to a drain, using minimum 1/2" NPT plumbing. The condensate line is limited to a maximum rise of 10 feet in order for the steam pressure to adequately force the condensate through the plumbing. Any higher rise requires a pump.
If the steam boiler to which this kettle is installed has a condensate return (closed loop system), a 1/2" steam strainer, a 1/2" steam trap, and a 1/2" check valve must be installed on the output (condensate) side of the kettle.

KETTLE OPERATION
1. Ensure that there is an adequate steam
supply to the kettle.
2. Turn the Steam Control Valve (11) to the open position by turning the knob counter­clockwise, then allow the kettle to preheat.
NOTE: 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. Fill kettle with product to desired level.
4. When the product has reached
the desired temperature, regulate the heat, as required, by turning the Steam Control Valve (11) clockwise for less steam, and therefore, a lower temperature.
5. When cooking is complete, close the Steam Control Valve (11) by turning the knob clockwise.
MIXER OPERATION
1. Turn Mixer Start Switch (2) to “ON”.
2. Adjust Steam Control Valve (11)
to desired setting.
FOR KETTLE/STEAMER COMBINATIONS:
If the boiler in a steamer is supplying steam to a kettle, always heat the kettle first. After the kettle contents are heated, and the boiler's steam pressure returns to normal, the steamer may be used. Pressure steamer compartments should be sequentially started, and preheated before cooking.
NOTE: As with cleaning food soil from any cookware, an important part of kettle cleaning is to prevent food from drying on. For this reason, cleaning should be completed immediately after cooked foods are removed. Please read the "Care and Cleaning" instructions for detailed kettle washing procedures
Marine Lock
If your unit is equipped with a Marine Lock (10) to prevent accidental tilting, it must be inspected daily to
insure it moves freely and automatically locks into place when kettle is returned to upright position.
Use the following procedure to tilt the kettle.
1. Securely grasp the Kettle Tilt Handle (4).
2. Push the Marine Lock (10) button down to
unlock tilting mechanism.
3. Pull the Kettle Tilt Handle (4) to tilt the kettle.

STAINLESS STEEL EQUIPMENT CARE AND CLEANING
(Suppied courtesy of Nafem. For more information visit their web site at www.nafem.org)
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 proper 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.

PRESSURE RELIEF VALVE TESTING PROCEDURE
The pressure relief valve (optional on kettles) must be checked at least twice a year as part of the normal maintenance performed.
1. Open steam valve and preheat kettle.
2. Stand to the side of the pressure relief valve
discharge tube and pull ring three or four times to insure free movement. Hold valve open for two seconds each time, insuring there is rapid steam escape each time.
3. If valve appears to be sticking replace pressure relief valve. If foreign material is discharged, replace pressure relief valve and eliminate the source of contamination.
STEAM TRAP
To remove line condensate that forms inside the steam jacket, each kettle should be equipped with a steam trap in the line of the kettle outlet to the drain. A good steam trap at startup releases air and wet steam into the drain line for a few minutes, then holds the steam jacket. During cooking, the trap periodically releases accumulated condensate. If the kettle's cooking performance becomes inadequate after long use, replacement of the steam trap with a new one may restore kettle operation to peak efficiency.
MARINE LOCK
Inspect lock at least twice yearly.
1. Check for excessive play or wear on pivot. Adjust or replace as required.
2. Insure lock is catching over the centre of the stop pin and not bent to one side or the other. Adjust or replace as required.
