Setup
- Unpacking: Carefully remove all packaging materials and inspect the appliance for any damage. Keep packaging for future storage or transport.
- Initial Cleaning: Before first use, clean the interior of the pot, the lid, and the grid insert with warm soapy water. Rinse thoroughly and dry.
- Placement: Place the appliance on a stable, heat-resistant, and level surface. Ensure there is sufficient space around the unit for ventilation. Do not place it near flammable materials or heat sources.
- Power Connection: Ensure the power cord is securely plugged into a grounded electrical outlet. The appliance operates on 220-240V, 50/60Hz.
- Insert Grid: Place the internal grid insert at the bottom of the pot. This prevents jars from touching the heating element directly.
Operating Instructions
General Operation
- Fill the pot with the desired liquid or place jars on the internal grid. Ensure the liquid level is appropriate for your task (e.g., covering jars for preserving). Do not exceed the MAX fill line.
- Place the lid securely on the pot.
- Plug the appliance into a power outlet. The power indicator light will illuminate.
- Use the Temperature Control Knob to set the desired temperature (30°C - 110°C).
- Use the Timer Control Knob to set the desired operating time (1-120 minutes). If you wish to operate continuously without a timer, set the timer to the 'ON' position.
- The appliance will begin heating. Once the set temperature is reached, the heating element may cycle on and off to maintain the temperature.
- When the timer expires, the appliance will automatically shut off. If operating continuously, manually turn the temperature and timer knobs to 'OFF' and unplug the unit.

- Prepare your food and fill it into appropriate preserving jars. Seal the jars according to their instructions.
- Place the internal grid insert at the bottom of the pot.

- Once the preserving process is complete and the appliance has cooled, carefully remove the jars using appropriate tools.

Mulled Wine and Hot Beverage Dispensing
The integrated tap makes this appliance ideal for heating and serving mulled wine, hot water, or other beverages.
- Fill the pot with your desired beverage. Do not exceed the MAX fill line.
- Set the temperature to your preferred serving temperature (e.g., 70-80°C for mulled wine).
- Set the timer or use the 'ON' setting for continuous heating.
- Once the beverage is heated, it can be dispensed directly from the stainless steel tap.
- Always ensure the tap is closed when not dispensing to prevent spills.
