7.1.3 Insufficient ice condenser temperature

CAUTION

Ensure sufficient ventilation. Do not place any paper, cloth, or similar

material behind or under the unit, since otherwise the air circulation will be

impaired.

The refrigeration unit is equipped with a protective device against

overpressure in the refrigeration system and with a thermal motor

protection switch.

The protective devices trip

• when the ambient temperature is too high

• when the air circulation of the heat exchanger of the refrigeration

system is insufficient

• when the refrigeration system is overloaded.

In these cases, the refrigeration unit will be switched off automatically. If the

permissible operating conditions are re-established after a cool-down

phase of several minutes, the refrigeration unit will be switched on again

automatically.

The malfunctions are displayed in the process and equipment information

window.

The minimum ice condenser temperature of approx. –85°C is reached

when the ice condenser is not loaded and the ice condenser chamber is

evacuated.
