The antifreeze in the extinguisher lets it still function in temperatures as low as -9°C. Being stored below 0°C will not only stop a non treated water extinguisher working, but is also likely to harm the internal lining. Your service technician may advise you it needs to be replaced and it won't be covered by the warranty and this could prove costly.
Our extinguisher still comes with the 5 year warranty that our other water extinguishers have and can still be commissioned and serviced by any competent technician to British Standard 5306 Part 3.
