E86
Error
– Leakage
At the beginning of the cooling process, the MM
500 control carries out a safety check to
determine whether the connecting lines between
the cryoPad and the MM 500 control are
connected.
The machine checks whether the sensors inside
the device cool down as expected and whether
operation is as intended.
•
Check whether the connection lines
between the cryoPad and the MM 500
control are tightly connected and do not
leak.
•
Check and ensure that no significant
leakage of nitrogen is visible. A nitrogen
leakage can be recognized by nitrogen
drops beading on the table surface until
they have evaporated.
•
Check whether ambient conditions for
room temperature and humidity have
been observed (see Chapter 4.5).
•
Turn off the main switch of the MM 500
control and the cryoPad and start the
process again.
•
If the error persists, please contact the
service of MM 500 control
