   1. In case the device has recently been moved, causing the refrigerant liquid in the compressor to get unsettled do not turn on the device for a period of 3 hours.
   2. When ready to operate, the unit has to run with empty GN containers covering the tub, for a period of 1 hour before food items / perishables can be placed on top of it.

USE INSTRUCTIONS

1. Connect the power cable to an electrical outlet (220-240V). A grounded three wire connection is necessary.

2. Push the power switch on the control panel to the ON position.

3. On the digital thermostat, while pressing the ‘SET’ button, press the up or down arrows to adjust the desired temperature that you wish the buffet to reach. When the SET button is released, the thermostat will display the current temperature inside the unit.

4. While the indicator light is illuminated, the cooling motor/heating element is working.

5. Cold Buffet: In order for the cool air to spread evenly and efficiently inside the unit use GN containers to cover the entire tub while operating. For maximum efficiency, do not operate the device with missing food containers.

   • Hot Buffet: The water level can be adjusted by the user. Since there will be a rapid steam
     generation in high temperatures, the water level has to be observed carefully by the user. It must be ensured that the tub has sufficient water inside for bain-marie function and for proper operation and safety of the device

6. In order to preserve the food at the adjusted temperature evenly and correctly, please take care to divide the food into serviceable portions in GN containers before placing into the device.

2. Do not put hot food and drinks into the unit
3. Cold Buffet: Adjust the thermostat to lower temperatures (3 to 5°C recommended)
4. Cold Buffet: Do not operate the unit while exposed to direct sunlight, or hot ambient temperatures (max. recommended temp. 25°C, relative humidity 60%)
5. Hot Buffet: Do not operate the unit while exposed to cold temperatures while food items are uncovered without lids. This might cause uneven temperatures in the food items.
