Before installation check that the pipes (iron, plastic or rubber) are internally clean so as not to clog the nozzle of the ejector.
A foot or check valve.When assembly is complete, fill completely pipes and pump body with clean water. Formaintaining efficient priming isthere must be a certain one in the circuit pressure, so it is advisable to mount a membrane tank on the delivery of the

Before installing the pump verify that all the tubes (iron, plastic or rubber) are clean inside to avoid any obstruction of the ejector nozzle. TO foot valve or a check valve must be installed at the foot of the ejector. After the pump is installed, fill tubes and pump body completely with clean water. To preserve an efficient priming a specific pressure in the circuit is necessary, therefore it is recommended to install a membrane tank at the delivery of the pump
