The leak sensor is wet. The leak sensor reports leakage.
• Replacement part as required
• Cloth or tissue
When resolving leakage, observe the safety guidelines and general rules

(} page 119).
1. Locate the source of the leak.
Location of the leak Steps
Flow connection 1. As leakage usually occurs at a connection, visually inspect
all components and connections in the flow path.
2. Tighten or replace the connection or component as
required.
3. Proceed with the steps below.
Nebulizer If liquid is visible on the nebulizer, leakage may have
occurred in the nebulizer.
1. Remove the nebulizer from the detector (see
the Nebulizer
2. Inspect the nebulizer for signs of leakage.
3. If no signs for leakage are present, re-install the nebulizer
(see
4. If signs of leakage are present, tighten or replace the
connection or component as required.
5. Proceed with the steps below.
2. With a cloth or tissue, thoroughly absorb all liquid that has collected
