Every pump should have a surge protector. Everyone suffers from power spikes, surges and dirty power – no one is exempt from this – so fitting your pump with a surge protector is a small price to pay to protect an expensive piece of equipment.
The Torrium®2 controller has an in-built metal oxide varistor (MOV) which protects it from electrical surges and spikes. The MOV is a sacrificial component and, should it be consumed due to repeated power surges or spikes, it will almost always blacken the viewing port. This will indicate a non-warrantable Torrium®2 failure. So, while the MOV offers added protection, we recommend a surge protector in addition – it’s just not worth the risk.
