  • Page 6: Product Overview

    2.2. Working principle The HSA functions as an open pump. The mixed liquor of wastewater and activated sludge is aspirated via the suction pipe. The helical impeller pumps the liquid axially up through the cylindrical volute, bends the liquid flow from axial to radial, and ensures that maximum kinetic energy is transferred to the water surface.

    It is strongly recommended not to start the aerator before the aerator is completely installed in accordance with the instructions described by ATB. Starting the aerator on dry land should not be done without making radical safety provisions.

    When you are using a different kind of mooring system, due to a specific situation, this must always be done in dialogue with, and with the approval of ATB. Any warranty claim for damage to the unit or others, due to a faulty designed mooring system, not approved by ATB, will be void.

  • Page 16: Installation

    If the electrical cable and mooring cables are supplied by ATB, they will normally already be connected to the HSA. If this is not the case, the mooring cables have to be attached to the mooring anchors at float side, and the electrical cable has to be connected inside the junction box of the motor, prior to the installation in the basin.
  • Page 17 If the water level-variation is such that 1 standard spring is not enough to compensate the variation of distance between the mooring anchor at basin side and float, please contact ATB to agree on the suitable guiding system. This guiding system should always be approved by ATB.
  • Page 18 ATB cannot be held liable for accidents caused by non-compliance with these instructions. Once the HSA is in its final position, the mooring cables can be tensioned. A sag of ± 2cm per meter mooring cable is recommended. Excessive tightening may damage the cables in the long run.

  • Page 19: Mounting Sequence For Hinged Arm System

    For vertical lifting of the unit, and to avoid handling damage, a double chain should be used (see drawing). Drawing 12b: Lifting of the hinged arm ATB WATER GmbH, Südstraße 2, 32457 Porta Westfalica, Germany, www.atbwater.com / Version: 07.11.2022 / Page 19 of 41...

  • Page 20: Mounting Sequence For The Vertical Guiding System

    Drawing 12c.: Mounting of the hinged arm to the wall fixation If the HSA is in the correct position, the electrical cable can be connected to the junction box on the side of the basin. Make sure to attach the electric cable to an anchor before it enters the junction box, to avoid that the electric cable pulls at the cable gland entering the junction box.
  • Page 21 As a safety precaution, no person shall walk under the aerator when it is lifted by the crane. If the basin is filled up before the HSA is placed between the guiding posts, a boat can be used to guide the HSA guiding brackets over the guiding posts.

  • Page 22: Electrical Cable And Wiring Instructions

    Anyway, the cable length should be a little oversized to be sure that the unit axis remains vertical (distance between HSA and basin edge x 1,2). 8. The strain relief is mounted on the flange support and gives the electric cable the right direction to the basin edge.
