8.1.5
Heat exchanger (only air-cooled freeze-dryers)
A lamellar heat exchanger is used for cooling the refrigerant that is
compressed by the refrigeration unit. This air-cooled heat exchanger is
located at the back of the unit (see chapter 7.3 - "Service contact").
Dust and dirt impair the cooling effect of the air flow. Dust on the lamellas
prevents the exchange of heat and, thereby, impairs the performance and
power of the refrigeration unit. Strong soiling may cause the unit to fail.
This is why the selected set-up location should be as clean as possible.
• Check the heat exchanger at least once per month for soiling and clean
it if necessary.
• Please contact the Christ service department if you have any queries
(see chapter 7.3 - "Service contact").
8.1.6
Electrical system
DANGER
Danger of life caused by electric shock
There is a risk of electric shock when touching current-carrying
components.
This may lead to ventricular fibrillation, cardiac arrest, or respiratory
paralysis.
• Only qualified electricians are authorised to perform work on the
electrical system of the freeze-dryer!
The electrical equipment of the freeze-dryer must be checked at regular
intervals by a qualified electrician. Defects such as loose connections or
burnt cables must be eliminated immediately.
