2.0 INTRODUCTION
DESCRIPTION
Models KTT-20E (20 gallon capacity) is electrically powered, self-contained, tilting kettles. Each
model has a jacket of double-wall construction forming a sealed reservoir around the lower twothirds of the kettle. The reservoir is charged with distilled water. Kettles are equipped with a
“clean lock” to hold kettle in cooking position or 105 degrees for ease of cleaning, removable
electric heating element and controls, including a low water cutoff device for protection of the
heating element. All models are of identical construction, except for kettle size and element
heating capacity.
BASIC FUNCTIONING
Self-contained kettles operate by generating steam in the kettle reservoir. The sequence of
operation is as follows:
1. Operator flips the power switch to the ON position and sets the temperature control dial at the
desired setting from 1 to 10 (140 degrees Fahrenheit to 285 degrees Fahrenheit, 60 degrees
Celsius to 140 degrees Celsius, jacket temperature).
2. Control circuit is normally completed to the temperature controller if the following conditions
exist:
3. Water level in the kettle reservoir is adequate to prevent circuit interruption by the low water
cut off device. An activated cutoff is indicated by the amber low water light turning on, and
the heating element shut off.
4. Kettle is in vertical position with circuit completed through the tilt interlock switch (Micro
switch).
5. Thermostatic control contacts close to energize contactor coils.
6. Power is supplied to the elements through closed power contactors.
7. As the temperature of water rises in the kettle reservoir, increase in steam pressure is
indicated on the pressure gauge.
When the temperature of steam in the reservoir reaches the setting shown on the temperature
control dial, the temperature controller opens to break the contacts and shut off the heating
element. On/off cycles will occur as required to maintain temperature control.

3.0 OPERATION INSTRUCTIONS
1. Ensure that the external electrical shut-off to kettle is on.
2. Check pressure gauge for correct cold kettle reading. Reading should be 25 - 30 In. Hg (84 100 kPa) of vacuum. If reading is not low enough, follow VENTING procedure prior to using
kettle.
3. Place power switch in ON position.
4. Preheat kettle by placing thermostat knob at ‘10' and wait until TEMPERATURE light goes
off.
5. Add food to be cooked into kettle.
NOTE
PREHEATING SHOULD NOT BE USED WHEN COOKING MILK AND EGG FOOD PRODUCTS
WHICH ADHERE TO HOT COOKING SURFACES. THESE FOODS SHOULD BE PLACED INTO
KETTLE BEFORE HEATING IS BEGUN.
6. Place thermostat knob at required temperature setting from 1 to 10 coinciding with a
temperature range from roughly 140 degrees Fahrenheit to 285 degrees Fahrenheit (60
degrees Celsius to 140 degrees Celsius) in reservoir.

4.0 CLEANING INSTRUCTIONS
The kettle interior and exterior should be thoroughly washed after each use in preparation of a
different food.
1. Add water and mild detergent to the kettle immediately after use.
2. Scrub kettle interior with a nylon brush.
NOTE
NEVER SCRAPE THE INSIDE OF THE KETTLE WITH METAL TOOLS, STEEL SCOURING PADS,
OR ABRASIVE CLEANERS. SCRATCHES WILL RESULT WHICH WILL SPOIL THE KETTLE’S
GENERAL APPEARANCE AND MAKE IT HARDER TO CLEAN AND MAINTAIN A SANITARY
CONDITION.
3. Loosen food which is stuck to kettle by allowing it to soak at a low temperature setting.
4. Rinse with clear water and dry.
WARNING
DO NOT HOSE DOWN UNDER ANY CONDITION. FAILURE TO COMPLY WILL VOID
WARRANTY.
5. Wipe down exterior, rinse and dry.
WARNING
IT IS NOT RECOMMENDED TO USE CLEANING AGENTS THAT ARE CORROSIVE.
Use of cleaning agents that contain chloride, acids or salts are corrosive and may cause pitting
and corrosion when used over a period of time; this will reduce the life of the appliance.
Should pitting or corrosion occur this is not covered by warranty.
Follow the recommended cleaning instructions. Use a mild detergent, warm water and rinse
thoroughly.

5.0 VENTING INSTRUCTIONS
Check vacuum/pressure gauge when kettle is cold. Gauge should be in the vacuum zone
between 25 - 30 In. Hg (84 - 100 kPa). If not, air is present which must be vented (removed) for
proper heating. Use the following procedures to vent air:
1. Place power switch in ON position; kettle empty.
2. Set temperature control thermostat to ‘10'. Heat kettle until heat indicator light goes off.
3. Using a 7/16" wrench, open bleed vent one full turn for 10 seconds and close.
4. Cool kettle. Check for proper vacuum of 25 - 30 In. Hg (84 - 100 kPa). If reading is not low
enough, repeat entire procedure, steps 1 to 3.
6.0 TILTING INSTRUCTIONS
Your kettle has the standard “Clean Lock” feature and may not be tilted without disengaging the
tilt knob located on the console at the top right. This feature locks the kettle in the upright
position and also allows the operator to lock the kettle at 105 degrees for ease of cleaning. To tilt
the kettle the full distance, the tilt lock knob must be disengaged from the cleaning position by
pulling out the tilt lock knob and tilting the kettle forward the full distance. Follow these steps to
tilt kettle:
1. Pull out the tilt knob at top right located on console.
2. Using kettle tilt handle pull kettle forward to desired angle of pour or until kettle locks at 105
degrees. The tilt knob can be released after the kettle has been tilted approximately 10E.
3. Kettle will lock in position at 105 degrees and may be tilted further by pulling the tilt lock knob
a second time allowing the kettle to tilt the full distance.
4. To return the kettle to the upright position, pull out the tilt lock knob and tilt the kettle upward
until it locks in the upright position. The kettle should not move in either direction once in the
upright position.
