Electrical contact
The pump's electrical contact should be connected
to a 230 V 50 hz socket by a qualified electrician in
accordance with the diagram above. This contact
no longer requires a 2-pole switch disconnecter.
The electrical contact should be equipped with a
slow-blow fuse of up to 10 A. The pump should
be disconnected from the mains before any main-
