Precaution
Electrical Hazard:
Disconnect and lock out electrical power
before installing or servicing the unit.
WARNING:
• Always wear protective gloves when
handling the pumps and motor. When
pumping hot liquids, the pump and its
parts may exceed 40°C (104°F).
• Maintenance and service must be
performed by skilled and qualified
personnel only.
• Observe accident prevention regula-
tions in force.
• Use suitable equipment and protec-
tion.
WARNING:
• A strong magnetic field is created
when the rotor is removed from or in-
serted into the pump head. This mag-
netic field can be harmful to pace-
maker wearers and others with medi-
cal implants. In addition, the magnetic
field may attract metal parts to the ro-
tor which can cause injuries and/or
damage the bearing of the pump.
