Check that the controls produce a healthy spark from the electrode to the earthing post and ignition is smooth and without delay. b) Turn thermostat off and then on.
OM/SM-TDH-CE 3. Servicing and Conversion on the gear housing until grease flows out of the bearings around the shaft. Put a liberal amount of grease on the gear to cover the arc of contact with the gear. Important Before attempting any servicing, ensure that the gas isolating cock is turned off and cannot be inadvertently turned on. Disconnect the electricity supply. Safety Valve At least twice monthly the safety valve requires checking to ensure that it works correctly.
OM/SM-TDH-CE filling must be removed to obtain efficient heating (Paragraph 3.2). information on the data plate for the type of gas being used. 3.2 Jacket Vacuum CAUTION TDH STEAM JACKETED KETTLES ARE DESIGNED TO USE TREATED, DISTILLED WATER ONLY. USE OF ANY OTHER WATER CAN CAUSE LIME ACCUMULATION ON INTERNAL SURFACES, AND WILL VOID ALL WARRANTIES. When the kettle is cold, a positive reading or a reading near zero on the pressure vacuum gauge indicates excess air in the jacket.

OM/SM-TDH-CE 5. User Instructions Regulations and Safety Precautions These Appliances have been CE marked on the basis of compliance with the Gas Appliance Directive, EMC and Low Voltage Directive for the Countries, Gas Types and Pressures as stated on the Data Plate. WARNING TO PREVENT SHOCKS, ALL APPLIANCES WHETHER GAS OR ELECTRIC, MUST BE EARTHED.
OM/SM-TDH-CE 5.1 Equipment Description 5.1.1 General 5.1.2 Available Options Groen model TDH are stainless steel, steam jacketed, table-top mounted, tilting kettles with a self-contained, gas-heated steam source. The kettle body is welded into one piece and furnished with a reinforced bar rim and welded "butterfly" pouring lip. The interior of the kettle is polished to a 180 emery grit finish, and the exterior is given a bright semi-deluxe finish.
OM/SM-TDH-CE 5.2 Lighting and Operation g. Turn the thermostat dial to the required setting. 5.2.1 Initial Kettle Lighting and Operational Readiness Check h. After 10-15 seconds the burners should light. The "heat on" neon will illuminate. After the TDH Kettle has been installed according to service and installation instructions, perform initial start-up as a test to ensure that the unit is operating correctly. Follow the steps below.
OM/SM-TDH-CE d) Tilt cut-off switch that shuts off all burners when the kettle is tilted. 5.2.3 Filling the Kettle Prior to operating the unit, clean out the kettle pan thoroughly, using hot water and detergent. When the kettle reaches the set temperature, the thermostat switch opens, stopping the signal to the gas control valve and causing the valve to shut off all gas flow. When the kettle cools below the set temperature, the thermostat switch closes and starts another heating cycle.
OM/SM-TDH-CE 5.3 Cleaning and Maintenance f) To remove materials stuck to the equipment, use a brush, sponge, cloth, plastic or rubber scraper, or plastic wool with the detergent solution. To minimize the effort required in washing, let the detergent solution sit in the kettle and soak into the residue, or heat the detergent solution briefly. IMPORTANT Disconnect the electricity supply before any cleaning is undertaken. The appliance must not be cleaned with a jet of water nor should it be steam cleaned.
OM/SM-TDH-CE i) When the equipment needs to be sanitized, use a sanitizing solution equivalent to one that supplies 200 parts per million available chlorine. Obtain advice on the best sanitizing agent from your supplier of sanitizing products. Following the suppliers instructions, apply the sanitizing agent after the unit has been cleaned and drained. Rinse off the sanitizing agent thoroughly. 5.3.5 Service-Periodic Maintenance A Maintenance and Service Log is included in this manual.
