3. Safety instructions
You must read this installation manual carefully before installing an HD pump, and respect all the
safety instructions.
HD pumps may only be used for the purpose for which they were designed.
An HD pump is designed to pressurise clean water from a reservoir into a pipeline system. HD pumps
may only be operated if they are installed in a suitable pipeline system.
During maintenance or repair, the power supply must always be disconnected, and the system
relieved of any residual pressure. In order to disconnect the power supply, the isolation switch of the
control element (control cabinet or similar) must be switched off and locked into position. After
maintenance or repair, always fully reconnect and test everything.
Only qualified personnel may carry out maintenance or repairs, and connect the electrical part of the
pump.
Always connect the earth wire to the terminal marked with the earth symbol.
Make sure the power is connected to an earthed end circuit, fitted with a circuit breaker with
appropriate rating.
Always respect all installation and safety regulations. Ignoring these rules may result in severe injury
to persons and/or damage to material.
When turning off the pump, make sure there is no residual pressure in the HD pump, and that it is
isolated from the rest of the system.
