WARNING
• The electrical installation may only be carried out
by a qualified electrical installer and in
accordance with national laws and regulations.
• The electrical installation must be done via an
all-pole work switch and earth fault switch
indirectly via the contactor controlled from the
pump's electrical connection. This is so that the
heater cannot be started without the water
circulating.
• The heater must be connected electrically ac-
cording to the wiring Diagram below.
Check against the nameplate on the product.
The electrical installation is carried out AFTER finished pipe
installation.
Fixed installation cable is recommended.
The heater must be connected via double contactors and locked over
the contactor of the circulation pump according to wiring diagram.
Check that the connection cable cannot come into contact with the
hot parts of the element.
When the electrical installation is complete, the lid is mounted on the
junction box.
