Operation; Troubleshooting - STA-RITE BOOST-RITE EVO Installation Manual

In case of intervention by this safety device as a result of overheating, disconnect from the power supply and leave the motor
to cool until it reaches an acceptable temperature. Before re-using the pump, check to verify the reasons which caused the
motor to overheat.
Check to ensure that certified cables are used in accordance with current regulations, with three cross-sections (2 + earth) of
at least 0.75 mm², with a maximum length of 2 m for the cable. If the cable is longer, the cross-section must be increased in a
suitable manner pursuant to currently applicable regulations.

OPERATION

Never allow the pump to run dry (without water). This will cause damage to the shaft seal and internal plastic components.
STARTING THE PUMP
In a flooded suction type application (pump below water level or in-line with primary pump), the pump starts as soon as the
shut-off valves in the inlet are opened.
In non-flooded applications, the pump must be primed by adding water within the suction piping and pump cavity.
The pump starts working after switching on. The suction action time depends on the suction height and the length of the suc-
tion line.
If the pump does not work, check that all shut-off valves are open and that there are no leaks in the suction line where air can
enter the water line preventing activation.
