5.6 Cooling coil
The standard cooling coil for connection to the tap water mains or to a commercial
refrigerating circulator widens the temperature range of the Shaking Incubator (minimum
operation temperature of the incubator: +20°C).
The connections of the cooling coil are situated at the back of the unit.
Please use hoses with a maximum inner diameter of 13 mm to connect with the connections
of the cooling coil. Connected hoses must be secured with hose clips.
6. Servicing, Maintenance and Clearing Possible Defects
Please make sure that no fluids come into contact with cable
connections or the electrical parts of the inside unit!
Before cleaning and/or opening the unit (only by an electrician!)
always pull the plug from the mains socket.
Danger of electrical shock !
6.1 Deblocking of the temperature cut-out
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 behind the control panel, can be
deblocked.
For deblocking, the control panel holder must be screwed off, and
the green deblocking knob at the left-hand side of the back wall must
be pressed. 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.
6.2 Shutdown caused by overload or power failure
The drive motor of the shaking device is protected against over-heating due to overload. The
device will be switched off.
Caution, after the motor has cooled down, the shaking device restarts automatically
(without gentle start-up control).
After a mains failure, the incubator does not restart automatically, but has to be started as
described in chapter 5.
If the unit is shut down due to a operation fault, always switch it off on the main switch
before opening the doors and touching parts in the unit's interior.
6.3 Exchanging the fuses
The unit's two fuses are situated in a drawer below the unit plug. In order to check or to
exchange these fuses, press the fixing clips on both sides of the drawer and pull.
The fuses may only be exchanged against fuses of the same type. Information on the
fuse type can be found on the nameplate next to the unit plug and in the spare parts list
of these operating instructions.
