    A73101880_F - Installation 4.5 Electrical installation 4.5.1 Check and configure the pump CAUTION: Isolate the power supply before changing the voltage. Failure to configure the pump electrical supply correctly can result in damage to the pump. Ensure that the voltage shown on the voltage indicator (refer to Figure: General view on page 9) on the motor cover corresponds with the electrical supply voltage.

  • Page 22: Leak Test The System

    A73101880_F - Installation WARNING: If pumping for a prolonged period above 100 mbar inlet pressure, use an exhaust silencer (refer to Silencer on page 34) or connect to an appropriate exhaust line. Before connecting the pump to the vacuum system, remove the plastic cap from the inlet and exhaust and ensure the inlet strainer is fitted to the pump inlet port.
