ASSEMBLY

Table-top models (12 gallon) must be positioned on a firm, level stand, or existing counter top, and bolted in place. These models are supplied with four threaded mounting bushings welded to the underside of the base. An optional support stand with level adjustable legs is available. Once the kettle is secure, screw tilt handle into the threaded hole provided at the right side of kettle.

Floor Type Leg Mount Models (20 gallon)

Position on a firm, level surface, and bolt flanged feet in place. Once the kettle is secure, screw tilt handle into the threaded hole provided at the right of kettle.

ELECTRICAL

ENSURE THE ELECTRICAL SUPPLY MATCHES THE KETTLE'S REQUIREMENTS AS STATED ON THE RATING LABEL.

This kettle is built to comply with applicable standards of manufacturers. Included among these approval agencies are UL, NSF, ASME/Ntl. Bd., CSA, ETL, and others. Many local codes exist, and it is the responsibility of the owner and installer to comply with these codes.

The electrical supply must match the power requirements specified on the kettle’s rating plate. The copper wiring must be adequate to carry the required current at the rated voltage.

Note: Maximum voltage for LVD (low volt directive for Europe) to be 440 volts for CE marked appliances.

INSTALLATION

WIRE CONNECTION

If unit does not have cord and plug option, remove the screw at the rear of the console cover and remove the cover. A wiring diagram is affixed to the underside of the cover. Feed permanent copper wiring through the cut-out in the rear or bottom of the console, and fasten to the three connection terminal block, which is mounted on the top of the console’s control panel. Be sure to connect the ground wire to the separate ground terminal connector (ground lug). Replace console cover and secure it with the screw.

The kettle is wired for 3-phase operation at the factory. For single phase operation, rewire the terminal block to that shown in the above diagram.

WATER

The sealed jacket of the electric kettle is precharged with the correct amount of a waterbased formula, and therefore, no water connection is required to the kettle jacket. The kettle can be equipped with optional hot and cold water taps, the taps require 1/2" copper tubing as supply lines.

INSTALLATION CHECKS

Although the kettle has been thoroughly tested before leaving the factory, the installer is responsible for ensuring the proper operation of kettle once installed.

Performance Checks

1. Supply power to the kettle by placing the fused

disconnect switch to the "ON" position.

2. Before turning the kettle on, read the vacuum/pressure gauge. The gauge's needle should be in the green zone.

3. Place the kettle's power ON/OFF switch to the "ON" position.

4. Turn the temperature control knob to "1" (Min.). The green LED light should remain lit, indicating the burner is lit, until the set temperature is reached (124°F/50°C). Then the green light will cycle on and off, indicating the element is cycling on and off to maintain temperature.

5. Tilt the kettle forward. After a few seconds the red "LOW WATER" light should be lit when the kettle is in a tilted position. This light indicates that the element has automatically been shut off by the kettle's safety circuit. This is a normal condition when the kettle is in a tilted position.

6. Raise the kettle to the upright position. The red "low water" light should go out when the kettle is upright.

7. Turn the temperature control knob to "10" (Max.) and allow the kettle to preheat. The green light should remain on until the set temperature (260°F/127°C) is reached. Then the green light will cycle ON and OFF, indicating the element is cycling ON and OFF to maintain temperature. Fill the kettle with cold water to the steam jacket’s welded seam.

8. When all testing is complete, empty the kettle and place the power ON/OFF switch in the “OFF” position.

CLEANING

After installation the kettle must be thoroughly cleaned and sanitized prior to cooking.

Temperature Control Knob (2) to the desired temperature setting (see above "Temperature Range Chart"). The Heat Indicator Light (Green) (3) will remain lit, indicating the burner is lit, until the temperature setting is reached. When the green light goes off, the heaters are off, and preheating is complete.

NOTE: When cooking egg and milk products, the kettle should not be preheated, as products of this nature adhere to hot cooking surfaces. These types of food should be placed in the kettle before heating is begun.

5. Place food product into the kettle. The Heat Indicator Light (Green) (3) will cycle on and off indicating the elements are cycling on and off to maintain the set temperature.

NOTE: Do not fill kettle above recommended level marked on outside of kettle.

NOTE: The Low Water Indicator Light (Red) (4) should not be lit when kettle is in the upright position during kettle operation. This light indicates that the elements have been automatically shut off by the kettle's safety circuit. It is, however, normal for the red light to come on when the kettle is in a tilted position.

6. When cooking is completed place On-Off Toggle Switch (1) to the "OFF' position.

7. Pour the contents of the kettle into an appropriate container by tilting the kettle forward. Care should be taken to pour slowly enough to avoid splashing off the product.

NOTE: As with cleaning food soil from any cookware, an important part of kettle cleaning is to prevent food from drying on. For this reason, cleaning should be completed immediately after cooked foods are removed.

APPROXIMATE BOILING TIMES
