## Features

- Kindly Tip 1: When you start using the pump, submerge the pump fully in water at a slight angle. Hold it underwater for 20–30 seconds to allow all trapped air to escape. Failure to remove air may prevent the pump from starting or discharging water properly.
- Kindly Tip 2: The device is not designed for continuous operation (e.g., as a circulation pump for ponds), as such use will significantly reduce the pump's service life. After each use, the impeller should be flushed to prevent sand and other debris from clogging the internal shaft.

- Multi Outlet Sizes: 3 different diameters outlets (1 inch ,1-1/4 inch, 1-1/2 inch) to adapte for different size hoses as needed according to the flow rate. The bigger the flow is, the wider the outlet should be
- Manual Mode: Set the switch to the MANUAL positon the pump will now not automatically switch off but carry out pumping, even if theremaining water level is reached and the pump runs dry. You should cut off the power immediately to prevent the coil from getting burned
- Automated Mode: Set the switch to the AUTO position. Once you have plugged the device into the socket, the pump will switch on automatically when the water exceeds the start-level and switch off when the stop-level hasbeen obtained.this means that the pump can be left on at all times and will keep the waterin a cellar or boat, for example, at the required level.bear in mind that this pump is notdesigned to be used continuously, it must be switched off at regular intervals
