Hard water contains calcium and carbonate ions, when the two react they create limescale. The Combi Care works by introducing a very small amount of food grade polyphosphate into the water feed, isolating the calcium in the water and preventing it from forming scale on the heat exchanger. This type of system is the most popular and effective method of treating water before it is heated in water heating units like combination boilers.

In addition, with the bright yellow cartridge change indicator you can even see when the cartridge change is due to be changed, should you forget. Cost - effective The Combi care’s easy change polyphosphate dosing cartridge only needs to be changed once every twelve months, saving you the chore and cost of multiple cartridges changes during the coming year. If you prefer to leave your filter, change to your friendly heating engineer it can easily be changed during your boiler’s annual service visit. One visit means less impact on the environment and more money in your pocket. Protect Appliances Heating appliances are protected from limescale – prolonging and preserving the life of your household appliances. Whole House Protection Protection for appliances helps keep the whole house protected from any build-up of scale. When To Change The Cartridge Average cartridge life expectancy is one year for a four person family.

## Questions & Answers

**Q: is this a direct replacement for a sentinel combiguard**
A: Hi, Thank you for your question. Yes it is, the BWT AC002400 Combi Care is a direct replacement for a Sentinel Combiguard. If you have more questions, please call us on 01494 8381 00 during normal office hours . Thank you

**Q: Can I change cartridges without turning off the water supply?**
A: You must turn the water off.
These units have a tendency to block so to the gentleman who did not have to turn his water off he needs to check the unit.

**Q: If these are not changes will this cause low water pressure ? Having trouble with a new house has this fitted to hot water under the boiler.**
A: These cannisters are supposed to be changed annually or more frequently if you use a lot of hot water. There is a pointer set to indicate the month it which the current cannister was fitted but if you're in a new house that might not be reliable. However I don't think an old and fully used cannister would cause low water pressure so I'd look elsewhere for the problem (but fit a new cannister anyway).

**Q: I'm struggling to take my old cartridge off, the thing won't budge! Any tips other than washing up liquid?**
A: Please check that firstly you have undone the small screw that locks the cartridge into place, you should then be able to unscrew the cartridge and pull it off. If the cartridge is still stuck then you can use x2 flat head screwdrivers to gently prise it off. Occasionally the cartridge media can clog in the spigot making it harder to remove, where this happens you may want to remove the metal elbow from the fitting, place this in hot water which will dissolve any residue enabling easy fitment of the next cartridge. If you would like any further advice please call our customer services team on 01494 838100, thank you!
