-
Site the unit on a level surface.
-
The unit must not be put into operation if its
temperature due to storage or transport has
been reduced below the dew point.
Wait approx. 1 hour.
-
For operation, contacts 1 and 3 on the remote
socket 15N must be joined. To do this, use the
remote plug from the accessories supplied with
the unit.
-
Further status signals are present on contacts 4,
5 and 6 of the remote socket 15N.
-
Connect the external coolant inlet and return
(maximum pressure (

8.1)).
-
Connect the load to the laboratory circuit.
-
Always ensure the largest possible inside di-
ameter in the external circuit (olives, hoses,
loads). This gives larger flow rates and therefore
better temperature stabilisation.
-
Secure hoses against slippage by using hose
clips.

Mains voltage is present on the contacts on the socket 15 N.
