7.4 Operation and control
WARNING
During operation of the cooling unit, individual components may heat up. Touching its
surface can cause burns. Use temperature-resistant protective gloves.
7.4.1 Switching on appliance
Press the main switch on the side of the unit.
The cooling power of the cooling unit is constant and cannot be regulated. The cool-
ing unit works at a constant power as long as it is switched on. The temperature is
controlled via the setting on the water bath. Do not operate the cooling unit when
the water bath heater is switched off. This could trigger the automatic shutdown
.
If the set temperature is above room temperature, it is recommended to switch off the
cooling unit.
7.4.2 Automatic switch-off
The cooling unit has a low temperature fuse which switches off the unit automatically
when the water temperature is at about 3ºC, to prevent icing over and possible damage
to the cooling element. When the water temperature reaches about 5 ºC, the cooling
unit switches back on again.
7.4.3 Function test
■ To check that the unit is pumping, pull off the suction tube from the tube suspender and
place a finger on it to test for suction. If there is no suction effect: See next chapter,
Troubleshooting.
7.5 Dismantling the hoses
1. Allow the wa ter in the water bath and the hoses to cool down first.
2. Drain the water from the water bath using the drain tap
until the raw joints are exposed.
3. Pull the hoses off the pipe connections
