    The pipe between the tank and the Neo-N should fill with water via gravity. Moleaer highly recommends installing clean-in-place (CIP)/sampling valves and isolation valves upstream and downstream of the Neo-N, especially in instances of unclean water. Refer to Figure 8 for Neo-N frame dimensions and suction and discharge fitting locations.

  • Page 27: Neo-N Suction Lift Installation

    The pipe between the tank and the Neo-N will not fill with water without the use of the pump. Moleaer recommends the check valve size is double the size of the suction pipe.

    S3 models come in single-phase and three-phase models while all Neo-N S5 models are three-phase. Before connecting power, verify the voltage, phase and amps requirements of your unit. Neo-N S2 and S3 models come in single-phase and three-phase models while all Neo-N S5 models are three-phase.

  • Page 32: Three-Phase Wiring

    Verify that the Neo-N is a three-phase model by checking the number of wires coming out of the main disconnect.
