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 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. On EP models use shims to
level kettle.

4. Mark hole locations on floor through anchoring holes provided in flanged adjustable feet, or
holes provided on pedestal base.

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 or
shims.

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.

INTRODUCTION

3.0 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 and thus 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 dial controlled to provide precise temperatures
throughout the range from slow simmer to rolling boil.

All stationary kettles are intended to be permanently floor mounted on legs with adjustable
flanged feet (EL models) or pedestals (EP models).

All kettles are equipped with a spring assist stainless steel lid covering the kettle bowl opening,
a sanitary stainless steel tangent draw-off valve for the removal of the food product from the
kettle bowl, and a safety relief valve plumbed to the kettle jacket.

4.0 CAPACITIES

All models are suffixed with either - 20F, - 30F, - 40F, or - 60F to indicate the capacity of that
kettle in US gallons. Thus an EL-40F indicates a full jacketed electrically powered steam kettle
mounted on legs with a capacity of 40 US gallons.

6.0 FUNCTIONING MODE

All electrically powered self steam generating kettles consist of a jacket charged with a solution
of water and antifreeze 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
simultaneously, TEMPERATURE pilot light will come on and contactors will close to allow
power to elements. Steam generation will commence and continue until the water contained in
the jacket reaches the thermostatic temperature, manually preselected, at which point the
Temperature (thermostat) Control will de-energize and open the contactors cutting off power to
heating elements and TEMPERATURE pilot light will go off. 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 the green vacuum zone on the gauge (approximately 20 to 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.

It should be noted that Temperature Controls (thermostats) used on these particular kettles
have an ultimate high limit temperature and this setting will prevent the heating elements from
ever generating steam pressure to reach or exceed the rated working pressure of these kettles.
Further should the Temperature Control fail, an unlikely condition, and consequently the circuit
to the heating elements remain energized, the Safety Valve will blow and release steam (i.e.,
water) from the self contained sealed kettle jacket and consequently lower the water level in the
jacket. A Safety Probe is incorporated in the circuit to sense depletion of the water level in the
kettle jacket and will not only activate the LOW WATER level indicator pilot light but also signal
the Liquid Level Control to switch off power and de-energize the circuit to the heating elements
(preventing element burn outs) until the water level is adequately replenished.
