Temperature Cut-out
As an additional safety precaution to over-temperature and under-temperature alarms, a thermostatic temperature cut-
out protects the unit against overheating. If either temperature regulator or fan motor should fail, the thermostatic over-
temperature cut-out will prevent overheating of the incubator. Only after the unit has cooled down, the temperature cut-
out, which is situated at the back of the Incubator, can be deblocked. For deblocking, loosen the black cap nut on the back
of the unit. Within the thread, a white plastic pin will now be visible which must be gently pushed inside (e.g. with a pen)
until a soft clicking sound can be heard. After deblocking, watch the operation of the Shaking Incubator carefully. If the
fault re-occurs, the cause has to be removed by a trained electrician.
8 Functional description
A cover made of 8 mm thick acrylic glass encompasses the cabinet interior. The interior is heated by a heating element in a
temperature range of 20 °C (from approx. 8 K above ambient) to 70 °C. The fan optimises the temperature distribution.
The built-in cooling coil permits works at set temperatures near to the ambient temperature. The temperature controller is
a PID controller and is equipped with a monitoring function that signals malfunctions and switches off the heating in case
of a malfunction.
The shaking device in the cabinet interior is driven by an a.c. motor, is electronically controlled and permits orbital motions
from 20 to 250 min
-1 and a fixed shaking amplitude of 30 mm.
The timer allows times to be set between 1 minute and 999 hours and 59 minutes. The timer continuously shows the
current remaining run time and emits an acoustic expiration signal.
The electronic regulation is microprocessor-controlled.
The housing is made of lacquered, moulded ABS resin elements and of electrolytically galvanised and powder-coated
sheet steel. The shaking platform, made of anodised aluminium, is equipped with four plastic pins for secure attachment of
accessory equipment. The heating element and the cooling coil as well as the rear wall and bottom plate of the interior are
made of stainless steel.
An RS 232 interface, set into the rear side of the unit, not only serves to register set and actual values of temperature and
shaking frequency, but also for remote operation through PC.
9 Maintenance, Support and Repair
Caution:
Before opening the Distillation Apparatus as well as before cleaning procedures, discon-
nect the unit from the mains! (Unplug the unit or switch off the main switch).
Danger of electrical shock!
Cleaning and Disinfection
The lacquered or powder-coated surfaces of the housing, the shaking platform made of anodised aluminium and the acryl-
ic glass cover may be cleaned with mild, non-abrasive and pH neutral detergents. Never use solvent-containing cleaning
agents. The stainless steel surfaces of the interior can be cleaned and the original shine be restored with commercial stain-
less steel polishing agents (e. g. “Helios Brillant“ from M/s Ecolab).
To disinfect the Shaking Incubator by a wipe process, approved disinfecting agents with proven compatibility with stainless
steel, lacquered or powder-coated steel and ABS resin elements, aluminium or acrylic glass can be used. The instructions
for use of the disinfectant must by all means be observed. If in doubt, test the disinfectant in a small local area. Should the
Incubator have been contaminated with dangerous substances, cleaning and decontamination measures must be carried
