Maintenance
C A U T I O N
Personal injury hazard. Only qualified personnel should conduct the tasks
described in this section of the manual.
N O T I C E
Do not disassemble the instrument for maintenance. If the internal components
must be cleaned or repaired, contact the manufacturer.
Clean the instrument
Clean the exterior of the instrument with a moist cloth and a mild soap
solution and then wipe the instrument dry.
Clean the syringe
Frequent use and dirty sample material make it necessary to clean the
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,
refer to Specifications on page 3.
1. Put a container with the cleaning solution on the docking module.
2. Push the LIFT/LOWER button to lower the sample probe.
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.
5. Push the LOAD button to send the cleaning solution to the drain.
6. Push the LIFT/LOWER button to raise the sample probe.
7. Put a container with distilled or deionized water on the docking
module.
8. Push the LIFT/LOWER button to lower the sample probe.
9. Push the CLEAN button to flush the syringe with the rinse water.
10. Repeat the flush with rinse water for a minimum of 10 cycles.
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.
How to clean spills
C A U T I O N
Chemical exposure hazard. Dispose of chemicals and wastes in
accordance with local, regional and national regulations.
1. Obey all facility safety protocols for spill control.
