Heater Operation
(continued)
(2) If you want to turn off the heater, turn the heater knob counter-
clockwise until you hear the ‘click’ sound.
Stirrer Operation
• Never place a cold glass vessel onto a hot top plate.
• There is a danger of liquid spills if containers are over-filled and
stirred at high speed. Always ramp up stirrer speed slowly and never
stir more rapidly than necessary.
The procedures of the stirring operation are as follows:
(1) Before activating the stirrer, check whether the stirrer knob is at
the ’0’ position. If not at the ‘0’ position, turn the stirrer knob counter-
clockwise all the way until you hear the ‘click’ sound.
(2) To activate the stirrer, turn the stirrer knob clockwise. With a ‘click’
sound, the stirring starts immediately. To set the stirring speed, turn
the stirrer knob at the desired position. For your safety, it is highly
recommended to increase the stirring speed in a gradual fashion.
(3) If you want to turn off the stirrer, turn the stirrer knob counter-
clockwise all the way to the ‘0’ position until you hear the ‘click’
sound.
