• The control panel circuit breaker is sized properly to protect the pump
against short-circuit.
• These pumps are electronically thermally overload protected. No additional
overload protection is required.

4.4 Pump installation requirements
• Install the pump according to the liquid flow direction arrows.
• Install the pump according to the allowed pump positions.
• Make sure that the pump is adequately supported by the piping system and
properly aligned to eliminate any stress on the pump or the piping
