We recommend that the pond pump is raised off the bottom of the pond. This will
prevent the pond from emptying completely in the event of pump failure.
You MUST fit the supplied non-return valve on your inlet pipework after the
circulating pump and before the filter. (See page 22 for more details)
We recommend that all electric work on your Nexus Automatic System
be done by a suitably qualified electrician.
