9.1 Replace detachable power cord
The device is equipped with a detachable power cord.
If the power cord needs to be replaced, ensure that the new one is at least
dimensioned for the device power requirements. Insufficiently dimensioned
power cords must not be used. See type plate for mains voltage and current
value.
We recommend only using original JULABO spare parts.
9.2 Check safety symbols
The safety labels affixed to the device must be clearly legible at all times. Their
condition must be checked every two years.
1. Check the safety signs on the device for legibility and completeness.
2. Replace defective or missing safety markings.
Safety signs can be reordered from JULABO.
The safety signs on the device have been checked.
9.3 Check the functionality of high temperature cut-off
This section describes how you can test that the high temperature safety
function is operational.

1. Set the display of the start screen so that it shows the high temperature cut-
off value.
