Recommended for use below five floors. Package List: 1 x Stainless Steel Jet Pump1 x Bottom Valve2 x Stainless Steel Adapter1 x Tape1 x Check Valve1 x Instructions Note: 1. The grounding wire must be grounded before use to prevent electric shock when the insulation is poor. For safety, be careful not to wet the power plug.2. Before grounding the wire, turn off the power. Never connect the ground wire to the gas pipe, otherwise there is a danger of explosion.3. Avoid running the pump without water, which will shorten the life of the pump, and the motor will heat up and be prone to failure.4. Do not use any liquid other than water. When using soluble substances such as benzoic acid, flammable substances such as gasoline and high‑viscosity liquids, it is easy to cause fire.5. In cold weather, when using the water pump, do not wrap the hydrogen motor or pump head with a quilt or cloth to prevent freezing, because the motor heats up and there is a danger of fire.6. Do not expose the pump to direct light to work, which will affect the service life of the pump.7. The water pump should be used as a towel during the suction process. After the palm of your hand is blocked, do not move around. It is best to fill the pump body! This test suction step can be tried several times to ensure that the pump does not suck air in.
