Background
Dear WOLF customers,
As part of our ongoing product monitoring, we have unfortunately discovered that the sealing rings installed in the UniAir ceiling outlet valves can be subject to premature ageing. In rare cases, the rubber compound used becomes brittle at an early stage. As a result, the valves can become detached from the ceiling mounting and fall down. This is a risk where it cannot be ruled out that a chain of certain circumstances may result in personal injury or damage to property. This affects the round and square Uni-Air valves with article numbers 2577879 and 2577880 from the production period January 2019 to July 2021.
For WOLF, the safety of our customers and the reliability of our products are of paramount importance. For this reason, we recommend that you promptly replace this seal with an improved version for valves that are already installed. With these new sealing rings, which are also installed in all new valves (new item numbers 2577988 and 2577989), brittleness no longer occurs.
The replacement is very easy to do yourself and should only take a short time. Below we have prepared a contact form for you to register to request replacement seals. You will also find both step-by-step instructions and a sample video for replacing the sealing rings on this page.
We regret any inconvenience this may cause and thank you in advance for your understanding and cooperation!
