How to use

Place the pump on a stable, level surface near the water source and connect the inlet hose to the water container using the G1 thread. Connect the outlet to your irrigation system or hose. Plug the pump into a suitable power supply using the 1.5 m cable. Use the large foot switch to switch the pump on and off; if an electronic pressure switch is installed, the pump will start and stop automatically according to system demand. After use, disconnect power and hoses and store the unit in a frost-free location.

Recommendations

Use the BP 4.500 GARDEN only for non-potable water sources unless the system is configured and maintained according to local regulations for service water supply. Fit the optional electronic pressure switch if automatic Start/Stop operation or household service water supply is required. Protect the pump from freezing and regular debris by installing suitable pre-filters on the inlet when drawing from unfiltered sources.
