1. Connecting a longer cable to the pump negative terminal (black) and positive terminal (red). The cable length will be designed as actual requirement, but make sure not to connect too long cable ,since the DC motor efficiency will be decrease during the super long cable. It is also suggested that at least 2mm2  cable to connect onto the pump. Finally, please confirm that the cable connectors is water proof and best seal.

2. Before you start wiring the pump to the solar panel,the pump needs to be submersed in water for at least 15 minutes before power is applied. Water is the lubrication for the pump and if it is not “preconditioned” properly the bearings will not be adequately lubricated. This will result in premature wear and failure of the pump and will refused the warranty.
