2.0 INSTALLATION INSTRUCTIONS
UNPACKING
Immediately after unpacking, check for possible shipping damage. If the kettle is found to be
damaged, save the packaging material and contact the carrier within 15 days of delivery.
Before installing, verify that the electrical service agrees with the specifications on the rating
plate located on the right side of the tilt console. If the supply and equipment requirements do
not agree, contact your dealer or Crown Food Service Equipment Ltd.
Select a location with drainage directly below the tangent draw-off. Allow sufficient rear
clearance from wall for kettle cover to lift upright freely and completely without obstructions.
INSTALLATION
1. The kettle must be installed in accordance with:
1. State and/or local codes.
2. In the USA, the National Electrical code, ANSI/NFPA-70 (latest edition). In Canada, the
Canadian Electrical Code, Part 1, CSA Standard C22.1 (latest edition).
2. Set the kettle in the installation location.
3. With the kettle in the upright position, place a carpenter’s level on top of the kettle and turn
the adjustable feet to level kettle side-to-side and front to back.
4. Mark hole locations on floor through anchoring holes provided in flanged adjustable feet.
5. Remove kettle and drill holes in locations marked on the floor (see installation diagram).
Insert proper anchoring devices to accommodate 5/16" size lag bolts (not supplied).
6. Reposition kettle. Re-level kettle by making necessary adjustments on flanged feet.
7. Bolt down kettle and seal with Silastic or other equivalent sealing compound. Sealant must
be applied not only to bolt heads but also around flanges or pedestal base making contact
with floor surface to fulfill NSF requirements. Wipe off excess sealant immediately.

2.0 INSTALLATION INSTRUCTIONS (Continued)
WARNING: Disconnect the electrical power supply and place a tag
at the disconnect switch to indicate that you are working on the
circuit.
ELECTRICAL CONNECTIONS
A Control Box with power supply equivalent to electrical rating of the kettle should be located
conveniently nearby.
Remove the wiring compartment cover and make electrical connections per wiring diagram
located inside the control housing cover panel. A waterproof electrical connection from power
supply to rear of control housing must be provided.
Kettle must be grounded in accordance with requirements of the National Electrical Code or
applicable local codes.
Ground kettle to terminal provided in control housing.
Once proper connections are made, replace wiring compartment cover, turn power ON and
check for proper operation.
SERVICE CONNECTIONS
All internal wiring for the kettle is complete.
If faucet is provided connect water supply and check for proper operation.
INSTALLATION CODES AND STANDARDS
Your electric tilting kettle must be installed in accordance with:
1. Provincial and local codes, or in the absence of local codes, with: C.S.A. C22.1 Canadian
Electrical Code, Part 1, or in the U.S.A., the National Electrical Code ANSI/NFPA-70 (latest
edition).
2. ANSI NFPA Standard #96, “Vapor Removal from Cooking Equipment,” (latest edition),
available from the National Fire Protection Association, Batterymarch Park, Quincy, MA,
02269.

3.0 INTRODUCTION
DESCRIPTION
All electrically powered kettles described and referred to in this manual are pressure vessels of
a double-wall construction forming a sealed jacket (chamber) enveloping the kettle bowl
surface.
The kettle bowl is the container for the food product which ideally should be a liquid or semiliquid consistency to achieve complete contact with the bowl surface. Food products will fully
absorb the heat transmitted through that surface from the pressurized steam generated in the
kettle jacket.
The jacket is intended to function as a self contained sealed chamber with a permanent solution
of water and antifreeze sufficient not only to immerse and thereby protect replaceable electric
heating elements, but also provide the steam source during the steam generating process.
The heating elements are thermostatically controlled to provide precise temperatures
throughout the range from slow simmer to rolling boil.
All tilting kettles are intended to be permanently floor mounted on legs with adjustable flanged
feet.
A sealed stainless steel tilt mechanism permits the kettle to tilt forward a full 90º for complete
emptying. The tilting mechanism is self locking for positive stop action.
CAPACITIES
All models are suffixed with either - 20F, - 30F, - 40F or -60F to indicate the capacity of that
kettle in US gallons. Thus an ELT-40F indicates a full jacketed electrically powered steam
kettle mounted on legs with a capacity of 40 US gallons.

FUNCTIONING MODE
All electrically powered self-generating, steam jacketed kettles, consist of a jacket containing a
permanent solution of distilled water sufficient to completely immerse and protect replaceable
electric heating elements.
To minimize tampering, the Safety Valve is plumbed toward the rear of the kettle jacket.
Should any component malfunction and cause the pressure in the jacket to reach the rated
pressure of the kettle, this protective device will open automatically and release excessive
pressurized steam.
When the Power Switch is turned ON and the Temperature Control (Thermostat) Knob dialed,
the TEMPERATURE pilot light will light and contactors will close to allow power to the elements.
Steam generation will commence and continue until the preselected temperature is reached, at
which point the contactors open, cutting off power to heating the elements. The
TEMPERATURE pilot light will then extinguish. When the temperature of the water in the
jacket drops slightly, the cycle will repeat itself thus making it possible to maintain any selected
precise cooking mode temperature.
The temperature required for the cooking process to function adequately must be greater than
the boiling point of the liquid food product. Further, the higher the temperature, the greater the
steam pressure attained in the jacket and consequently the quicker the cooking process. For
example, steam pressurized at 30 p.s.i. attains a temperature of 274º Fahrenheit.
Since air is an unsuitable media through which heat may be transferred, it has been removed
from the kettle jacket during testing at the factory. The Pressure Gauge should indicate
vacuum in the jacket in green zone on the gauge (approximately 20 - 25 inches Hg) when the
kettle is cold or has been inoperative for some time. The kettle jacket is intended to function at
all times as a completely sealed self-contained chamber and it is especially advisable not to trip
the safety relief valve during inoperative periods since this will break the vacuum seal and allow
air to enter the kettle jacket.
The Temperature Controls (thermostats) used in these kettles have been calibrated to prevent
the heating elements from generating steam pressure that would exceed the rated working
pressure of the kettle. In the unlikely event that the Temperature Control fails and the heating
elements remain energized, the Safety Valve will blow and release the excessive pressure and
steam from the jacket, consequently lowering the water level in the jacket. The Safety Probe
sensing depletion of the water level in the kettle jacket will not only activate the LOW WATER
level indicator pilot light, but also signal the Liquid Level Control to switch off power and deenergize the circuit to the heating elements (preventing element burn outs) until the water level
is adequately replenished.

4.0 OPERATION INSTRUCTIONS
WARNING: The kettle and its parts are hot. Use care when
operating, cleaning and servicing the kettle.
Ensure that the external electrical service to kettle is on.
Check pressure gauge for correct cold kettle reading. Reading should be in the green area of
the gauge indicating 25 - 30 In. Hg (630 - 730 mm Hg) of vacuum. If reading is not low enough,
follow VENTING procedure in Troubleshooting section prior to using kettle.
Place power switch to ON position.
Preheat 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 has begun.
Add food to be cooked into kettle.
