# Maintenance schedule
What you do to keep your BactoBox® working well, and how often.
Do these to keep your BactoBox® measuring accurately.
| What to do | When to do it |
| ------------------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------- |
| [Clean](/more/how-to-guides/clean-your-setup.md) | After every measurement |
| [Test your dilution liquid](/more/how-to-guides/test-your-dilution-liquid.md) | Every day if you use bulk dilution liquid |
| [Deep clean](/more/how-to-guides/deep-clean-your-setup.md) | Every week you use your BactoBox® |
| [QC test](/maintenance/qc-test.md) | Every week you use your BactoBox®, after every deep clean, and when you insert a new flow cell |
| [Annual preventive maintenance](/more/service-and-support/annual-preventive-maintenance.md) | Once a year |
## At the end of the day
Run a [Clean](/more/how-to-guides/clean-your-setup.md), power off your BactoBox®, and leave the tubing kit in the disinfection vial. For longer breaks, see [Shipping and storage](/more/service-and-support/shipping-and-storage.md).
## After more than a week without use
In weeks you do not use your BactoBox®, skip the deep clean and QC test. When it has been idle for more than a week, run these three before your first measurement.
1. [Deep clean](/more/how-to-guides/deep-clean-your-setup.md).
2. [Clean](/more/how-to-guides/clean-your-setup.md) with a disinfection vial.
3. [QC test](/maintenance/qc-test.md).
## Working with a dilution dispenser
If you use a dilution dispenser, replace the 0.22 µm syringe filter mounted on it at the start of each day. Replace it sooner if it squeaks or you need to press harder to dispense. Then [test your dilution liquid](/more/how-to-guides/test-your-dilution-liquid.md).
See [Replace the syringe filter](/more/how-to-guides/replace-syringe-filter.md) for the full procedure.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.
## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.
Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:
```
GET https://help.sbtinstruments.com/maintenance/maintenance-schedule.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
