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.
