Settings
The valve can be set using the adjustment knob [1], so that the desired temperature is
reached. The temperature is controlled using a sensor [5] located in the oil bath.
Turning the adjustment knob [1] in counterclockwise direction increases the tempera-
ture. Turning the adjustment knob in clockwise directing lowers the temperature.
Install the capillary tube without any sharp bends. Support the capillary tube at it's
ends. Supporting the capillary tube is especially important when vibrations may occur.
