Operating Manual Freeze Dryer ALPHA 1-2 LDplus
WARNING! Papers, cloths or similar items must not be put
behind the unit as the air circulation of the heat exchanger will not
work any more.
The freeze dryer should be horizontally aligned. The ambient
temperature should be within approx. +10°C and +32°C.
The refrigeration compressor of the freeze dryer is air-cooled.
Sufficient air circulation must be ensured. A distance of at least 30 cm
to the wall should be kept. The unit should not be positioned near
radiators or heat sources and direct insolation must be avoided.
In case of insufficient air circulation or too high ambient temperatures
pressure and/or temperature in the refrigerating system will increase.
This may cause an exceeding of the admissible operation pressure
and thus a breakdown of the freezing unit.
