INSTALLATION CHECKS
Although the kettle has been thoroughly tested before leaving the factory, the installer is responsible for
ensuring the proper operation of kettle once installed.
Performance Checks
1. Supply power to the kettle by placing the fused disconnect switch to the "ON"
position.
2. Before turning the kettle on, read the vacuum/pressure gauge. The gauge's
needle should be in the green zone.
3. Place the kettle's power ON/OFF switch to the "ON" position.
4. Turn the temperature control knob to "1" (Min.). The green LED light should remain lit, indicating the
burner is lit, until the set temperature is reached (124°F/50°C). Then the green light will cycle on and off,
indicating the element is cycling on and off to maintain temperature.
5. Tilt the kettle forward (tilting models only). After a few seconds the red "LOW WATER" light should be lit
when the kettle is in a tilted position. This light indicates that the element has automatically been shut off
by the kettle's safety circuit. This is a normal condition when the kettle is in a tilted position.
6. Raise the kettle to the upright position (tilting models only). The red "low water" light should go out when
the kettle is upright.
7. Turn the temperature control knob to "10" (Max.) and allow the kettle to preheat. The green light should
remain on until the set temperature (260°F/127°C) is reached. Then the green light will cycle ON and
OFF, indicating the element is cycling ON and OFF to maintain temperature. Fill the kettle with cold
water to the steam jacket’s welded seam.
8. When all testing is complete, empty the kettle and place the power ON/OFF switch in the “OFF”
position.

4. Preheat the kettle by turning the Solid State
Temperature Control Knob to the desired
temperature setting (see above "Temperature
Range Chart"). The Heat Indicator Light
(Green) will remain lit, indicating the burner is
lit, until the temperature setting is reached.
When the green light goes off, the heaters are
off, and preheating is complete.
NOTE: Do not fill kettle above recommended level
marked on outside of kettle.
NOTE: The Low Water Indicator Light (Red) should
not be lit when kettle is in the upright position during
kettle operation. This light indicates that the elements
have been automatically shut off by the kettle's
safety circuit. It is, however, normal for the red light
to come on when the kettle is in a tilted position.
6. When cooking is completed place On-Off Heat
Switch to the "OFF' position.
7. Pour the contents of the kettle into an
appropriate container by tilting the kettle
forward. Care should be taken to pour slowly
enough to avoid splashing off the product.
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. .
The accompanying chart shows approximate times
required for electric kettles of various capacities to
boil water. Temperature control knob must be set at
"10" (Max.) throughout the heatup period. Water will
boil about 1/3 faster if the kettle is filled only to the
outer steam jacket's welded seam, resulting in a
kettle filled to 2/3 capacity.
* High Wattage is only available with 3 phase units
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 food should be placed in the kettle
before heating is begun.
5. Place food product into the kettle. The Heat
Indicator Light (Green) will cycle on and off
indicating the elements are cycling on and off
to maintain the set temperature.

STAINLESS STEEL EQUIPMENT CARE AND CLEANING
(Supplied 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.
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.

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.
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.

Regular inspection and maintenance of units is essential to obtain trouble free and safe operation of
equipment. Inspections must include testing of the pressure relief valve and checks of the operating
system to insure that it has not been altered.
No safety features designed into the equipment should ever be tampered with. Tampering
with or bypassing controls is a very dangerous practice and unfortunately we have seen several cases of
this. Following is a short list of the most common and the most dangerous alterations performed on kettles.

HYDRAULIC OIL
REPLACEMENT PROCEDURE
One of the most important maintenance tasks is to
change the hydraulic oil yearly. Under heavy
usage the oil should be changed every nine
months. It is important to change the oil regularly
to prevent its breakdown which leads to the
damaging of components.
The oil filter should be changed at the same time
as the hydraulic oil. A clean filter prevents
particles from damaging the other components in
the system.
Replace the hydraulic fluid as follows:
⇒ Disconnect power to unit.
⇒ Remover the front top panel on the main
console.
⇒ Remove chrome vent cap from breather pipe
located beside electric motor.
⇒ Remove plug bolt from bottom left front corner
of main console to drain oil into your catch
pail.
⇒ Remove oil filter.
⇒ Replace plug bolt.
⇒ Refill unit through breather pipe using
approximately 12 U.S. gallons of Tellus 32
hydraulic oil (oil should be 6 1/2" deep in
tank).
⇒ Install new oil filter (Part# SE50094).
⇒ Replace chrome vent cap and front top panel.
⇒ Reconnect power to unit.
⇒ Run unit to remove any air in the lines.
NOTE: Mixer may run rough and noisy for one or
two hours if air has become trapped in the line.

SOLENOID VALVE
MAINTENANCE
NOTE: It is not necessary to remove the valve
from the pipeline for repairs.
WARNING: Turn off electrical power supply and
depressurize valve before making repairs.
Cleaning
All solenoid valves should be cleaned periodically.
The time between cleanings will vary depending
on the medium and service conditions. In general,
if the voltage to the coil is correct, sluggish valve
operation, excessive noise or leakage will indicate
that cleaning is required . Clean valve strainer or
filter when cleaning the valve.
Preventive Maintenance
1. Keep the medium flowing through the valve as
free from dirt and foreign material as possible.
2. While in service, the valve should be operated
at least once a month to insure proper
opening and closing.
3. Depending on the medium and service
conditions, periodic inspection of internal
valve parts for damage or excessive wear is
recommended. Thoroughly clean all parts.
Replace worn or damaged parts. However, for
best results, replace all parts as supplied with
a Rebuild Kit.
Solenoid Valve Exploded View Drawing
Ordering Information
Parts marked with an asterisk (*) in the Solenoid
Valve Exploded View Drawing are supplied in the
Rebuild Kits.
1. Faulty Control Circuits: Check the electrical
system by energizing the solenoid. A metallic
"click" signifies that the solenoid is operating.
Absence of the "click" indicates loss of power
supply . Check for loose or blown fuses, open
circuited or grounded coil, broken lead wires
or splice connections.
2. Burned-Out Coil: Check for open-circuited
coil. Replace coil as necessary. Check supply
voltage; it must be the same as specified on
nameplate.
3. Low Voltage: Check voltage across the coil
lead. Voltage must be at least 85% of
nameplate rating.
4. Incorrect Pressure: Check valve pressure.
Pressure to valve must be within range
specified on nameplate.
5. Excessive Leakage: Disassemble valve and
clean all parts. If leakage continues, replace
all parts as supplied with a Rebuild Kit.

PROCEDURES
The kettle's water level must be maintained at the
proper level to submerge the heater elements. Under
normal operating conditions, the sealed water reservoir
should never require the addition of water.
If the red "low water" light comes on during use (while
the kettle is in an upright position), the water level has
reached a critically low level. The low water protection
control has automatically shut off the heater elements.
The following procedure must be completed before
further use:
NOTE: Have a qualified service technician repair the
leakage problem and add water to the unit. Ensure that
the red "low water" light is on when the kettle is upright.
On tilting kettles, it is normal for the red light to come on
when the kettle is in a tilted position, as the elements
are not submerged in water at this point.
DISTILLED WATER REQUIREMENTS
3. Pull Pressure Relief Valve (A) open to insure vessel
is not pressurized.
4. Remove Pressure Relief Valve (A).
Replace Pressure Relief Valve (A) with Street Elbow (B).

PRESSURE GAUGE "O" RING REPLACEMENT
Cleveland Kettles are designed to withstand adverse operating conditions associated with high
volume cooking facilities. To achieve this, internal components are completely sealed from the
outside environment.
However, if the Pressure Gauge "O" Ring fails or is not replaced with the gauge, damage can
result when water penetrates through this area. This occurs because the bottom cover seal that normally
keeps water out now traps the water in.
Two major reasons for water penetration at the Pressure Gauge are:
A/ Gauge is loose so the "O" Ring is not providing a proper seal.
B/ Gauge is replaced without the "O" Ring being replaced.
NOTE: Kettle shown
upside down for clarity.

YesReplace defective safety thermostat.
NoGo to step #6.
YesReplace defective contactor/s.
NoGo to step #6.
Check contactor contacts for pitting. Voltage
across contactor terminals while in a closed
position indicates a poor contact. Replace
contactor/s as necessary. Check elements
for short at ground or an open circuit. If
element/s are defective contact the factory.
Elements are not field replaceable.
7.Remove wire from low water level probe
and ground it to the body of the kettle.
Do the contactors now energize?
8.Is there 16VAC present at output of 16
VAC transformer?

Page 43
9.Measure continuity of ON/OFF switch. Is
it operating properly?
YesGo to step #10.
NoReplace defective ON/OFF switch.
10.Unplug control box and measure the
resistance across potentiometer. Is it
approximately 0 ohms at maximum
setting and 50,000 ohms at minimum?
11.Remove edge connector from control
box. While kettle is cold or thermistor is
removed and allowed to cool, measure
the resistance between edge connector’s
pins #2 and #7. Is it approximately
100,00 ohms?
B/ Problem: Kettle heats too slowly or not hot enough. (Note: normal max. operating pressure with an
empty kettle is 30-35 psi.)
Possible Causes
1.Air in jacket requires
venting.
2.Defective safety thermostat.
3.Defective potentiometer.
4.Defective thermistor.
5.Defective contactor/s.
YesGo to step #11.
NoReplace defective potentiometer.
YesSpray contact cleaner on control box
terminals and edge connector. Try box
again, if the problem still exists, replace
defective control box.
NoReplace defective thermistor.
6.Defective control box.
7.Defective elements/s.
Fault Isolation Procedure
StepTest
1.In a cold state, does the pressure gauge
read in the green zone?
2.Do the contactors shut off too early?
(before reaching normal maximum
operating pressure.)
3.Does the green LED remain illuminated
after the contactors shut off?
4.Unplug control box and measure the
resistance across potentiometer. Is it
approximately 0 ohms at maximum and
50,000 ohms at minimum setting?
