8.4 Resolving Leakage
When
The leak sensor is wet. The leak sensor reports leakage.
Parts required
Replacement part as required
Additional items required
Cloth or tissue
Preparations
When resolving leakage, observe the safety guidelines and general rules
for maintenance and service as presented in
chapter 7 Maintenance and
Service, page 111 .
Follow these steps
1. Locate the source of the leak.
As leakage usually occurs at a connection, visually inspect all
components and connections in the flow path.
If liquid is visible in the leak tray and/or on the flow cell inlet or
outlet, leakage may have occurred in the flow cell. Remove the flow
cell from the detector (see
section 7.7.2, page 128 ). Inspect the flow
cell for signs of leakage.
♦ If no signs for leakage are present, reinstall the flow cell (see
section 7.7.3, page 130 ).
♦ If signs of leakage are present, proceed with the steps below.
2. Tighten or replace the connection or component as required.
3. With a cloth or tissue, thoroughly absorb all liquid that has collected
in the leak tray and under the leak sensor. Be careful not to bend the
sensor.
4. Allow the sensor to adjust to the ambient temperature for a few
minutes.
5. If leakage is no longer reported, you can resume operation.
