3.4.3 Manometer
The device types with bypass have a manometer for reading the set pump
pressure. The pump pressure is regulated using the bypass adjustment wheel
on the rear side.
3.4.4 Level indicator
The fill level of the heat transfer liquid in the circuit can be read using the
level indicator.
n
The top arrow indicates the maximum liquid level of the machine.

The bottom arrow indicates the minimum liquid level of the machine.
1 Maximum level
2 Minimum level
3.4.5 Cooling unit
The cooling unit includes the following components:
n
Compressor
A hermetically sealed compressor is used in the cooling unit. The com-
pressor is equipped with overload protection, which trips on the com-
pressor temperature and compressor current consumption.
n
Condenser
In air-cooled condensers, the condensation heat is discharged to the
environment. The fresh air is sucked in through the front of the device
using a fan, heated and discharged on the rear of the device.
n
Evaporator
In the internal bath, heat is discharged using a pipe coil evaporator.
