Model EC-20T (20 gallon capacity) is an electrically powered, self-contained, tilting kettle. The appliance 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 “clean lock” to hold kettle in cooking position or 105 degrees
the heating elements.
B F
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 at the desired setting from
1 to 10 (90 degrees Fahrenheit to 285 degrees Fahrenheit, 32 degrees Celsius to 140 degrees Celsius, jacket
temperature).
2. Control circuit is normally completed to the temperature control if the following conditions exist:
b) Kettle is in vertical position with circuit completed through the tilt interlock switch.
3. Thermostat control closes 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 shown on the temperature control dial, the
maintain set temperature.

rear clearance from wall to tilt freely and completely without obstruction.
3. On hole locations marked, drill holes and insert expansion shields to accommodate 5/16” size lag bolts.
5. Bolt down kettle and seal with Silastic or other equivalent sealing compound. Sealant must be applied not only to bolt
excess sealant immediately.
6. A control box with power supply equivalent to electrical rating of kettle should be located conveniently nearby.
7. A waterproof electrical connection from power supply to rear of control housing must be provided.
8. Ground kettle to terminal provided inside control housing.
9. Turn power ON and check for proper operation.
WARNING

OPERATION
I
1. Ensure that the external electrical service to kettle is on.
2. Check pressure gauge for correct cold kettle reading. Reading should be in the green vacuum zone (25 - 30 In. Hg or
635 - 762 mm Hg of vacuum). If reading is not low enough, follow VENTING INSTRUCTIONS in this Section prior to
using kettle.
3. Place power switch in ON position.
5. Add food to be cooked into kettle.
6. Place thermostat knob at required temperature setting from 1-10 coinciding with the following table:
1 90 Fahrenheit 30 Celsius
2 118 Fahrenheit 42 Celsius
3 138 Fahrenheit 54 Celsius
4 158 Fahrenheit 64 Celsius
5 178 Fahrenheit 76 Celsius
6 200 Fahrenheit 88 Celsius
7 220 Fahrenheit 100 Celsius
8 240 Fahrenheit 111 Celsius
9 260 Fahrenheit 122 Celsius
10 280 Fahrenheit 134 Celsius
9. Add water to kettle for cleaning purposes.
10. Wash kettle thoroughly. See CLEANING INSTRUCTIONS.
T I
Your kettle has a 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 10°.
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.

Check vacuum/pressure gauge when kettle is cold. Gauge should be in the green vacuum zone (25 - 30 In. Hg or
635 - 762 mm Hg of vacuum). If not, air is present which must be vented (removed) for proper heating. Use the
following procedures to vent air:
1. With the kettle empty, place power switch in ON position.
3. Using a 7/16” wrench, open bleed vent (rear of kettle) one full turn for 10 seconds and close.
4. Cool kettle. Check for proper vacuum in the green vacuum zone (25 - 30 In. Hg or 635 - 762 mm Hg of vacuum ). If
reading is not low enough, repeat steps 1 to 3.
It may be necessary to replenish water in the jacket when the low water indicator comes on. Do so as follows:
2. Lift handle of pressure relief valve to release vacuum in kettle. (Relief valve is at left rear of kettle).
3. Remove air vent nut at the rear of the unit.

compound suitable for steam at 50 psi.
6. Vacuum must be re-established. (See Venting Instructions in this Section).
OPERATION
CAUTION
Under normal operating conditions a “try lever test” should be performed every two months. Under severe service
conditions, or if corrosion and/or deposits are noticed within the valve body, testing must be performed more often.
A “try lever test” should also be performed at the end of any non-service period.
CAUTION
to avoid any bodily contact.
CAUTION
High sound levels may be experienced during “try lever” test. Wear proper safety equipment and exercise extreme
care! Test at, or near, half of the operating pressure by holding the test lever fully open for at least two seconds to

the kettle has cooled enough to touch it.
1. Rinse the inside of the kettle thoroughly and drain to remove any food particles.
2. Using a nylon brush, clean the kettle with a mild detergent and water. Never use steel wool or scouring powder as it
will scratch stainless steel. Plain steel wool can leave small pieces of steel which can rust.
3. Rinse the inside of the kettle thoroughly with clean water. Tilt the kettle to allow the detergent and water solution to drain.
4. Wipe the exterior of the kettle with a clean, damp cloth.

Grasp the valve knob and slowly pull out the valve stem. Wash the valve stem, disk and handle. Insert a nylon brush,
2. Replace the valve stem assembly and turn the hex nut until snug. Rinse the kettle with clean warm water.
CAUTION
The equipment and its parts are hot. Use care when operating, cleaning and servicing.

WARNING
Disconnect the power supply to the appliance before cleaning or servicing.
WARNING
Never spray water into electric controls or components!
CAUTION

stain. The appliance should not be heated and remain at room temperature during the entire cleaning process.
2. If the stain resists removal, additional exposure time with vinegar may be required, to a maximum of one hour.
3. Thoroughly wash all of the vinegar away with fresh clear water. Dry the surface completely and allow one hour before
using the appliance to cook.
Following daily and period maintenance procedures will prolong the life for your equipment. Climatic conditions - salt air -
To remove normal dirt, grease or product residue from stainless steel, use ordinary soap and water (with or without
detergent) applied with a sponge or cloth. Dry thoroughly with a clean cloth. Never use vinegar or any other corrosive
cleaner.
To remove grease and food splatters or condensed vapours that have baked on the equipment, apply cleanser to a
damp cloth or sponge and rub cleanser on the metal in the direction of the polishing lines. Rubbing cleanser as gently
NEVER RUB WITH A
CIRCULAR MOTION.
Soil and burn deposits which do not respond to the above procedure can usually be removed by rubbing the surface
with SCOTCH-BRITE™ scouring pads or STAINLESS scouring pads. DO NOT USE ORDINARY STEEL WOOL as any
NEVER USE A WIRE BRUSH, STEEL
SCOURING PADS (EXCEPT STAINLESS), SCRAPER, FILE OR OTHER STEEL TOOLS. Surfaces which are marred
TO REMOVE HEAT TINT: Darkened areas sometimes appear on stainless steel surfaces where the area has been
subjected to excessive heat. These darkened areas are caused by thickening of the protective surface of the stainless
steel and is not harmful. Heat tint can normally be removed by the foregoing, but tint which does not respond to this
procedure calls for a vigorous scouring in the direction of the polish lines using SCOTCH-BRITE™ scouring pads or a
STAINLESS scouring pad in combination with a powdered cleanser. Heat tint action may be lessened by not applying or
by reducing heat to equipment during slack periods.
CONTROL PANEL: The textured control panel should be cleaned with warm water and mild soap. Never use an abrasive
cloth or steel wool. Never use cleaning solvents with a hydrocarbon base.
