The tap water booster pump must be installed in accordance with the "installation mode" display in the horizontal or vertical installation, the direction of water flow should be consistent with the direction of the arrow on the pump body, and as far as possible, installed in the lowest position away from the water level. In order to facilitate the use and maintenance, in the pump inlet pipe should be installed a valve.
When the pumped liquid level is lower than the pump impeller surface or pump shaft around the pump should be installed check valve, the outlet end of the connection of a tee for the diversion of water, in the first use should be given to the pump filled with water, and will screw the plug tight. Pipe connections should be tight, especially the inlet pipe can not leak or will reduce the pump head or pumping water. Do not run the pump for a long time without water in the pump chamber to avoid damaging the seals.
The motor coil is equipped with a safety protector, the pump failure or pumping water caused by the motor temperature exceeds the specified value, it can automatically cut off the circuit, to remove the fault motor temperature drop, it can automatically resume operation. Booster pump motor for capacitor operation type motor, pump factory rotation direction has been adjusted, such as the need to replace the capacitor or rewiring, please according to the pump body arrow direction sign wiring.
In order to ensure the safety of use, please must use the three-pronged safety socket with grounding wire. When the pump is found to be leaking, stop the machine immediately to check to prevent internal leakage, and replace the mechanical seal if it is leaking from the connection part with the motor. Check whether the power supply is connected. Whether the voltage of the power supply used is consistent with the working voltage of the pump. If the above a, b normal; please dismantle the pump, open the pump cover, clear the pump of foreign objects, and then the pump cover, tighten the adjustment to normal.
