# Smart PFM (MK1) Maintenance schedule

## Here is an overview of the standard maintenance schedule for the Smart PFM (MK1).

### Maintenance

**Weekly**

- Confirm the instrument reads 0 ppm when clean water is passed through the cell.
- Engage manual cleaning actuator to force alarms and confirm that all alarms are ON.

**Bi- monthly inspection (Every 2 months)**

- Inspect the desiccator for discoloration or saturation

**Every 6 months**

- Replace the desiccator every 6 months, or sooner if discoloured.

**Yearly**

- At yearly intervals (or when necessary) the wiper ring on the cleaning system assembly should be
- replaced. This can be ordered from Rivertrace as part number: 111722.

• It is advised to verify the calibration of the system on a yearly basis. It is possible to verify the   
accuracy of the monitor by purchasing a Calibration Check kit. This can be purchased directly from   
Rivertrace, one of our agents or service centres. If the calibration check is carried out by one of our   
service centres, then a calibration check certificate will be issued by them on behalf of Rivertrace.

**5 Years**

- The Measuring cell should be verified by a Rivertrace approved service centre.
