Safety and Operating Instructions
Electrical Safety
To prevent electric shock, install a leakage circuit breaker or ground fault protector and ensure proper grounding.
Voltage Requirements
The operating voltage must be within +5% to -12% of the rated voltage; otherwise, the motor may overheat or burn out.
If the power source is far from the pump, use thicker power cables to prevent voltage drop and operational failure.
Startup Check
Turn on the power and let the pump run idle for about 2 minutes to verify proper startup, operation, and correct rotation direction.
Installation Guidelines
Secure the pump firmly and connect the inlet to the foot valve using steel pipes or reinforced hose (avoid overly soft tubing to prevent collapse).
The foot valve must be vertical and positioned at least 30 cm above the bottom to avoid sucking in silt.
For first-time operation, fill the storage tank completely. If the pump fails to discharge water within seconds, repeat priming. Later uses do not need refilling.
