syringe more often. Clean the syringe daily or weekly to make sure that it
works properly. Use a mild detergent for standard applications. To find
whether a different cleaning solution is compatible with the instrument,

3. Push the LOAD button to fill the syringe with the cleaning solution.
Note: If the plunger does not move easily in the syringe barrel, remove the
plunger, wipe the plunger with alcohol and wet the plunger seal with deionized
water.
4. Allow the solution to stay in the syringe for a minimum of 30 minutes.

Troubleshooting
Back-flush the system
A large particle can reduce or stop the liquid flow. If this occurs, a flush
in the reverse direction can push the particle out through the sample
probe.
1. Put a small waste container under the sample probe.
2. Push the LIFT/LOWER button to lower the sample probe.
3. Push and hold the BACK-FLUSH button until the back-flush cycle
starts.
The syringe fills with liquid from the drain tubing. When the syringe
closes, the liquid is sent through the sensor and sample probe.
4. Repeat the back-flush cycle as necessary until a flush in the forward
direction with a clean sample flows at a normal rate.
