Please Note: It is not recommended to retrofit the new SMA vacuum breaker into machines other than the KB90, Leva, and Strada. No tests have been made on other models. As the mechanism for sealing is driven by temperature, the distance from the boiler, and the connection components, this may cause the vacuum breaker to perform incorrectly.
