To install the DAYLIFF DDP50A Domestic Pump, please follow the guidelines provided in the user manual:
1. Choose a dry, well-ventilated, and weatherproof location with an ambient temperature not exceeding 40°C.
2. Place the pump on a solid flat surface, ensuring that the shaft is in a horizontal position.
3. Make sure that the diameter of the suction pipe is at least the size of the pump suction inlet. If the suction depth exceeds 4 meters, use a one-size larger diameter pipe for maximum pump performance.
4. If there is negative suction (pump above the water level), angle the suction pipe slightly upwards towards the pump inlet to avoid airlocks. The pipe should be immersed in water by at least 0.5m, and a good-quality foot valve must be fitted.
5. Ensure all suction pipe connections are completely airtight. The diameter of the delivery pipe should be chosen to suit the flow rate and pressure required at the delivery point, but it must not be smaller than the pump outlet size. It is advisable to fit a non-return valve and isolating valve on the delivery outlet, especially if the delivery pressure exceeds 20 meters.
Please refer to the user manual for more detailed instructions and diagrams on the installation process.
