Why aren’t any bubbles coming out of my filter?

According to your description, a small bubble appears periodically in the impeller housing of the CristalProfi and is then transported out of the filter.

If air enters the filter system, this may be an indication that a seal is no longer tight or that connecting pieces don’t close tightly, for example. Since there is a constant slight low pressure during operation, this doesn’t necessarily become noticeable. In the event that there is a leak of this kind, you can test by switching off the filter temporarily, in which case a small amount of water would escape at the leaky spot. Caution: This test should only be carried out with careful monitoring.

Another possibility: The filter material may be very heavily soiled, which may result in the formation of fermentation gas which is pressed out of the filter periodically.

The third possibility: Adding carbon dioxide through the suction nozzle, which we discourage.

PUSH messages from JBL

What are PUSH messages? As part of the W3C standard, web notifications define an API for end-user notifications that are sent to the user's desktop and/or mobile devices via the browser. Notifications appear on the end devices as they are familiar to the end user from apps installed on the device (e.g. emails). Notifications appear on the end user’s device, just like an app (e.g. for emails) installed on the device.

These notifications enable a website operator to contact its users whenever they have a browser open - it doesn’t matter whether the user is currently visiting the website or not.

To be able to send web push notifications, all you need is a website with a web push code installed. This allows brands without apps to take advantage of many of the benefits of push notifications (personalised real-time communications at just the right moment).

Web notifications are part of the W3C standard and define an API for end user notifications. A notification makes it possible to inform the user about an event, such as a new blog post, outside the context of a website.

JBL GmbH & Co. KG provides this service free of charge, and it is easy to activate or deactivate.
