The pump has a built-in over current fuse and protection, temperature protection and basic
overvoltage protection. It does not need additional thermal protection switch. Connection leads
should be capable of carrying rated power and 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.
