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.

NOTE

The refrigeration units are activated with a certain time lag. Refrigeration
unit 2 is solely intended for the heat exchanger. It enables the control of
the shelf temperature via the heat transfer medium. Refrigeration unit is
primarily intended for cooling the ice condenser. However, if more cold is
required on the shelves (especially during freezing), it will be temporarily
switched over to the heat exchanger, which leads to an increasing ice
condenser temperature.

An increase of the ice condenser temperature during the freezing phase is
a regular part of the freeze-drying process.

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.

Process and error messages

The control system displays the complete process and error messages
(see chapter 6.7.1.1 - "Main window "Manual"", dialogue box "Process and
equipment messages"), which is why they are not included in this operating
manual.

You can order these documents from our service department.
