3、 Installation and wiring methods
Operate according to product specifications
Qualified products include grounding wires. If the grounding wire color is yellow or green, "high-level enclosure", "special requirements", and "low-level enclosure" devices should be provided for these two wires

4、 The installation method of heavy hammer
1. Thread the wire of the float switch through the concave circular hole in the center of the heavy hammer, and gently push the heavy hammer to make the plastic ring embedded above the circular hole fall off due to the pushing force of the wire head. (If necessary, you can also use a screwdriver to remove a plastic ring), and then place the cable with the detached plastic ring on the desired water level due to the weight hammer.
2. Gently push the hammer to pull out the cable until the center of the hammer grips the plastic ring. As long as the heavy hammer is lightly fastened in the plastic ring, it will not slip off. If the plastic ring is damaged or lost, it can be replaced by fastening the same light bare copper wire into the cable.
Heavy hammer is a required accessory only attached
Please pull the wires directly to the control box and avoid using intermediate connectors as much as possible. If there are no other connectors, do not immerse the cable connectors in water.
