2.0 INTRODUCTION
DESCRIPTION
Models KTT-6E (6 gallon capacity) and KTT-10E (10 gallon capacity) and KTT-12E (12 gallon
capacity) electrically powered, self-contained, countertop, tilting kettles. Each model has a
jacket of double-wall construction forming a sealed reservoir around the lower two-thirds of the
kettle. The reservoir is charged with distilled water. Kettles are equipped with a 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 FUNCTION
Self-contained kettles operate by generating steam in the kettle reservoir. The sequence of
operation is as follows:
1. Operator turns the power switch to the ON position and sets the temperature control dial to
the desired setting from 1 to 10.
2. Control circuit is normally completed to the temperature controller if the following conditions
exist:
A. 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.
B. Kettle is in vertical position with circuit completed through the tilt interlock switch.
3. Thermostat control contacts close to energize contactor coils.
4. Power is supplied to the elements through closed power contactors.
5. As the temperature of water rises in the kettle reservoir, increase in steam pressure is
indicated on the pressure gauge.
6. When the temperature of steam in the reservoir reaches the setting of the temperature
control dial, the temperature controller opens to break the contacts and shuts off the heating
element. On/off cycles will occur as required to maintain temperature setting.

3.0 OPERATION INSTRUCTIONS
1. Ensure that the external electrical shut-off to the kettle is on.
2. Check pressure gauge for correct cold kettle reading. Reading should be in the green
vacuum zone. If reading is not in the vacuum zone, follow VENTING INSTRUCTION prior to
using the kettle.
3. Place power switch in ON position.
4. Preheat the kettle by placing thermostat knob at ‘10' and wait until TEMPERATURE light
goes off.
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.
5. Add food to be cooked into the kettle.
6. Place thermostat knob at required temperature setting from 1 to 10 coinciding with a
temperature range from roughly 165EF to 289EF (74E C to 143E C, jacket temperature.)

10. Wash kettle thoroughly. See CLEANING procedure.
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 near top right of 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.

EXTINGUISHING MEDIA: Water fog or fine spray, carbon dioxide, dry chemical, foam. Alcohol
resistant foams (ATC type) are preferred if available. General purpose synthetic foams
(including AFFF) or protein foams may function, but much less effectively. Do not use direct
water stream. May spread fire.
MEDIA TO BE AVOIDED: Do not use direct water stream.
FIRE FIGHTING INSTRUCTIONS: Keep people away. Isolate fire area and deny unnecessary
entry. Burning liquids may be moved by flushing with water to protect personnel and minimize
property damage. Burning liquids may be extinguished by dilution with water. Do not use direct
water stream. May spread fire. Fight fire from protected location or safe distance. Consider
use of unmanned hose holder or monitor nozzles. Use water spray to cool fire exposed
containers and fire affected zone until fire is out and danger of re-ignition has passed.
Immediately withdraw all personnel from area in case of rising sound from venting safety device
or discolouration of the container. Move container from fire area if this is possible without
hazard.
PROTECTIVE EQUIPMENT FOR FIRE FIGHTERS: Wear positive-pressure self-contained
breathing apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet,
