• The connection line is to be placed in such a way that it can under no
circumstances come into contact with the pipe and/or the pump and
motor housing.
• When pumps are used in systems with water temperatures above
90 °C, a suitably heat-resistant connection line must be used.
• This pump is equipped with a frequency converter and may not be
protected by a residual-current-operated protection circuit. Fre-
quency converters can impair the function of residual-current-oper-
ated protection circuits.
Exception: residual-current-operated protection circuits which have
a selective type B universal-current-sensitive design are allowed.
• Labelling: RCD
• Trigger current: > 30 mA
• Check the current type and voltage of the mains connection.
• Observe the name plate information for the pump. The current type
and voltage of the mains connection must correspond to the details
on the name plate.
• Mains side fuse protection: max. permissible 25 A
• Take additional earthing into account!
• The use of a miniature circuit breaker is recommended.
