Faq - Frequent questions
How do you clean the glass of the flow meter of a manifold for an underfloor system?
To clean the flow meter glass, please read our article in the blog:
https://www.caleffi.com/it-it/blog/come-si-fa-pulire-il-flussimetro-di-un-collettore-impianti-pavimento
The series 668 manifolds have flow meters that cannot be serviced. If you mare unable to clean them by flushing water, they should be replaced with the spare part, code F69937.
