UML Advise for replacing the Auto Cartridge.
Recreational Use: Replace every two years or by the REPLACE BY date whichever is sooner. It is recommended your lifejacket is inspected annually. Refer to your lifejacket manual and keep to service intervals.
Commercial/Professional Use: Replace annually. Do not exceed the REPLACE BY date in any 1-year period. SOLAS approved life jackets are required to be serviced by an authorised service station annually.
The key advise to take from the UML guidance above is that the “Replace by Date” is not a date that the cartridge should be used until. It is a date you should not go beyond.
It is important that you purchase the correct rearming kit. UML have several different inflators so if you aren’t sure, please get in touch.
On the picture of the inflator are two green indicators. The top indicator advises on the cylinder; is it empty or lose? The bottom indicator advises on the cartridge; has it been discharged or perhaps it is not functioning as it should?
It is important to note that inflator indicators such as these are a guide. If they are RED then something is wrong. If they are GREEN then something might still be wrong – you still need to check regularly. Do not think that green always means OK – keep up with your regular checks.
Items containing CO2 cylinders can be shipped anywhere in the UK although express shipping is not possible to some destinations. International shipping is possible, but more difficult. Please check my carriage info page for more detail.
