5. Maintenance and controls
5.1

Cleaning

Every 6 - 8 months the inside of the unit should be freed of dust. At the same time,
retractable grids at the rear side of the appliance should be freed of dust using a dry
dusting brush. Care must be taken that no cables are pulled out or tubing bent or
damaged in the process.
For a thorough cleaning of the inside of the appliance (e.g. after a long period of sto-
rage) use lukewarm water containing some detergent or other mild domestic cleaner
on the plastic surfaces.
5.2

Shut down/non-use

If the thermostat-controlled incubator remains unused over a long period it should be
switched off (disconnect plug from the mains or switch off or remove the fuse) and
cleaned (see above!). To avoid bad odours the door should remain open during this
period of non-use.
Prior to all work on the inside of the unit the mains plug of the thermostat-
controlled incubator must be pulled out of the mains connection (not just a
switching-off at the mains).
The appliance has an automatic defrosting device. Defrosted water collects in an
evaporator tray and is evaporated automatically. Attention must be paid that the de-
frosted water can drain off freely through the drainage opening in the back panel of
the incubator. The drainage opening should, when necessary be cleaned with the aid
of a suitable device (e.g. bottle brush).
5.3

Preparation for transport

The appliance must be sent shock-proof-packed (preferably in its original packing). The
packing is to be labelled as correspondingly ("keep dry/attention, fragile").

6. Troubleshooting and repair

Attention !!!
Before undertaking any repair work disconnect plug from mains! Only trained
specialists should work on electrical devices.
Although switched ON - no display or control function
Cause: safety fuse defect
Remove defect fuse and replace it with a new fuse (slow-blow 6,3 A).
Correct display of inside temperature but no regulation to the temperature
setpoint
Cause: compressor of the cooling system or control unit is defect
Contact your dealer or supplier, if necessary send in the control unit or thermostat-
controlled incubator for repair (original packing if possible!).
