1. Efficient Pressure ReliefEnsure proper installation by aligning the pressure relief hole with the water tank drain hole. This design effectively prevents water from splashing onto the floor or itself during pressure relief. 2. Safe Water IntakeTo prevent contamination, it is crucial to securely tighten the water inlet pipe and filter after locking the booster pump. This keeps impurities away from the pump body and protects its functionality. 3. Clear Pressure MeasurementsThe pressure gauge provides clear readings for normal water supply pressure at 0.3 MPa and rise pressure at 0.4 MPa. Typically, water pipeline pressure tests range between 0.8 1 MPa, with household pipeline tests maintained for 2 to 4 hours, depending on the specific environment. 4. UserFriendly Seal Ring GuideInstall the hose connection last to avoid damaging the pressure hose. The sealing ring comes preinstalled from the factory, so customers do not need to install it upon delivery. A replacement set of sealing rings is included for future use.
