Groen Steam Jacketed Kettle TDB-20

NOTICE: Contact Groen or an authorized Groen representative when repairs are required

Is the pressure/vacuum gauge showing a vacuum of 20 to 30 inches when the kettle is cold?

If the gauge does not show a vacuum of 20 to 30 inches, see “Jacket Vacuum” on page 14

Is the jacket water level above mid point of the round sight glass?

If the jacket water level is low, see “Jacket Filling and Water Treatment” on page 14

WARNING! KEEP WATER AND SOLUTIONS AWAY FROM CONTROLS AND ELECTRICAL EQUIPMENT. NEVER SPRAY THE SUPPORT HOUSING OR ELECTRICAL CONNECTIONS

CAUTION! MOST CLEANERS ARE HARMFUL TO THE SKIN, EYES, MUCOUS MEMBRANES, AND CLOTHING. PRECAUTIONS SHOULD BE TAKEN. WEAR RUBBER GLOVES, GOGGLES OR FACE SHIELD, AND PROTECTIVE CLOTHING. READ THE WARNINGS AND FOLLOW THE DIRECTIONS ON THE LABEL OF THE CLEANER CAREFULLY

Clean food-contact surfaces as soon as possible after use. If the unit is in continuous use, thoroughly clean and sanitize the interior and exterior at least once every 12 hours

WARNING! AVOID ANY DIRECT CONTACT WITH HOT SURFACES. DIRECT SKIN CONTACT COULD RESULT IN SEVERE BURNS

Scrape and flush out food residues. Be careful not to scratch the kettle with metal implements

Prepare a hot solution of the detergent/ cleaning compound as instructed by the supplier. Clean the unit thoroughly. A cloth moistened with cleaning solution can be used to clean controls, housings, and electrical conduits

Rinse the kettle thoroughly with hot water, then drain completely

As part of the daily cleaning program, clean soiled external and internal surfaces. Remember to check the sides of the unit and control housing

To remove stuck materials, use a brush, sponge, cloth, plastic or rubber scraper, or plastic wool with the cleaning solution. To reduce effort required in washing, let the detergent solution sit in the kettle and soak into the residue. Do NOT use abrasive materials or metal tools that might scratch the surface. Scratches make the surface harder to clean and provide places for bacteria to grow. Do NOT use steel wool, which may leave particles in the surface and cause eventual corrosion and pitting

1. At least twice a year, grease the two trunnion bearings

2. The bearings are located within the kettle support housing

3. Remove the access panels from the support housing with a screwdriver to gain access to the grease fittings. Use a lithium-based, multipurpose grease. When the access panels are removed, the mounting bolts for the trunnion bearings and tilt switch can also be checked for tightness

4. On the crank-tilt models, the gear housing has fittings for proper lubrication of moving parts. Because the gears do not run in oil, periodic lubrication with grease is necessary

5. Frequency of lubrication will depend on operating conditions, but the service should be performed at least once every six months

NOTE! Add grease through the Zerk fittings on the gear housing until you see grease flow out of the bearings around the trunnion shaft. Also place a liberal amount of grease on the gear to cover the arc that is in contact with the worm gear. When finished, reassemble access panels to support housing. Electrical wiring should be kept securely connected and in good condition;

Warning: Ensure the kettle is cold before starting the procedure

Enter the initial pressure/vacuum gauge reading

Is there water or product in the kettle?

Start the unit as per the 'Operation' section of the manual

Enter the pressure/vacuum gauge reading after starting the unit

Has the pressure/vacuum gauge reached a positive pressure reading of five PSI?

Release the trapped air and steam by pulling up on the safety valve for about 1 second

Repeat the previous step, then let the chain snap back into the closed position
