Installation & Compatibility Notes

This is a non-self-priming pump - the suction point must always be installed below the water level of the tank, and the pump itself must be installed on a flat, dry surface that will not flood in heavy rain. Confirm your required flow rate and head fall within the selected model's range, and that pipework matches the connection size. Add a PS-01 controller (PS-01A for CPW-300) for automatic start/stop and run-dry protection - sold separately. Use a qualified installer for all electrical and plumbing connections, and contact Zisabo if you are unsure which model is right for your application.
