Position the water container relatively lower than the planter to prevent water from the bucket from flowing directly into the planter due to siphoning.2. Use the inlet pipe filter correctly and do not use large particles of sewage as a water source to avoid blocking the pipes or pump.3. Before setting up the automatic programme, you can use the manual operation to test the required watering duration and flow rate.4. Please use indoors.5. When not in use for a long period of time, unplug the adapter, remove the batteries and place the main unit in a suitable dry environment.6. When using battery power only, battery life depends on overall conditions such as operating frequency, operating strength and battery performance. When the low battery indicator starts flashing, the battery needs to be replaced promptly. When replacing the batteries, all 4 batteries need to be replaced at the same time.7. The automatic watering device can only water intermittently and cannot be used as a pump to transport fluid media continuously for a long period of time, otherwise the service life of the host diaphragm pump will be seriously reduced.8.
