Accessing the Liquid Handling Module
CAUTION
Damage to tubes and liquid spills
Keeping tubes connected on the left side of the instrument while pulling out the liquid
handling module will damage the tubes and might lead to liquid spills.
Disconnect any external pressure supply, drainage or connections to an external water
bath for tray cooling prior to accessing the liquid handling module.
CAUTION
Damage to the instrument
Damage may lead to a non-operational instrument.
• Do not lift the liquid handling module upwards, outside the instrument. The module
is connected to the main frame by two flat ribbon cables and two flexible tubes.
When lifting it up, the liquid handling module might come off the guiding rail and the
connections might be affected.

connected and place them in front of the instrument.
3 Carefully pull the liquid handling module out from the main frame.
