How long will the Mag Defender last?
Mag Defender has been developed to last for the lifetime of the
boiler, normally ten years. It provides continuous protection and
comes with a five year warranty.
How do I isolate the valves?
Simply turn the valves to the marked OFF position using the
spanner provided. Important: Remember to switch off the
electrical supply to the boiler when servicing the Mag Defender.
Will the Mag Defender affect my pacemaker?
As with all magnetic products, if you have a pacemaker caution
should be taken when handling the Mag Defender at all times.
When the Mag Defender is installed, the magnetic field outside
the canister is approximately one tenth of an average fridge
magnet.
