The pump has a built-in over current fuse and protection, temperature
protection and basic overvoltage protection. It doesn’t need an additional
thermal protection switch. Connection leads should be capable of carrying
rated power and should be properly fused. Ground lead connection is
essential for safety. It should be connected first. Grounding is only meant for
pump safety. Pipes should be grounded separately.
• Connection of the pump must be carried out by qualified
personnel,
• Connection of the connecting cable must be done in a
manner that ensures it is never in contact with the casing
of the device, due to the high temperatures of the casing,
• The device should not be used by children and persons with
reduced physical, sensory or mental abilities, or with lack
of experience or knowledge, unless they are supervised
or instructed on the use by a person responsible for their
safety,
• Children should always be supervised to prevent playing
with the device.
