Periodically, Evogro will send you a task to replace the filters in the trays. To replace the filter, carry out the following steps:
Remove the tray from the Evogro cabinet
Rotate the elbow through 90°
Simultaneously press the blue or black collect ring at the end of the elbow connector towards the fitting and pull the pipe firmly out.
Insert the new pipe and filter into the elbow connector. Push firmly inwards then pull out to check it is secured.
Rotate the elbow back through 90° so that the pipe is vertical and the base of the filter touches the base of the tray
