Page 11: Safety
Safety The general and specific health and safety hints are described in detail in the separate booklet Safety Instructions for Sulzer Products Type ABS. If anything is not clear or you have any questions as to safety make certain to contact the manufacturer Sulzer. Lifting, transport and storage Lifting ATTENTION! Observe the total weight of the Sulzer units and their attached components! (see nameplate for weight of base unit). -
Page 12: Storage Of The Units

Page 15: Installation
The electrical connection is carried out in accordance with Section 8 Electrical connection. NOTE We recommend that Sulzer installation accessories be used for the installation of the RCP recirculation pump and RW mixer. Particular attention must be paid to the safety regulations covering work in closed areas in sewage plants as well as good general technical practices. -
Page 16: Guide Tube Installation Rcp
7.1.2 Guide tube installation RCP The safety hints in the previous sections must be observed! ATTENTION The discharge line and the required flange DIN EN 1092-1 PN6 should be installed on site before starting the installation of the guide tube. The DIN-flange should be installed so that none of the holes in the flange are on the axis line but are symmetrically on either side of it. -
Page 17: Lowering Of The Rcp Along The Guide Tube
7.1.3 Lowering of the RCP along the guide tube To ensure the RCP will tilt enough to lower correctly on the guide tube, the angle of the pump created by the lifting hook when suspended by the hoist has to be checked prior to lowering. For this purpose, begin lifting the pump from a horizontal surface and check that the rear end of the fixing support rises 20- to 40- mm from the floor before the front end begins to lift clear (see drawing below). -

Page 27: Checking Direction Of Rotation
Checking direction of rotation When the units are being commissioned for the first time and also when used on a new site, the direction of rotation must be carefully checked by a qualified person. The direction of rotation (propeller rotation) is correct if the propeller when viewed from the rear over the motor housing rotates in a clockwise manner (see arrow). Figure 23: Checking direction of rotation When checking the direction of rotation take care that no injury can be caused by the rotation of the propeller or the resulting airflow. Do not place a hand or other part of the body near the propeller or the hydraulics! The direction of rotation should only be altered by a qualified person. -
Page 28: Maintenance
This applies particularly if the unit is continually switched off by the current overload in the control panel, by the thermal sensors/limiters of the thermo-control system or by the seal monitoring system (DI). The Sulzer service organisation would be pleased to advise you on any applications you may have and to assist you in solving your aerating problems. NOTE... -
Page 29: Inspection And Maintenance Intervals
In these cases the unit should be immediately switched off and inspected. If no fault can be found or the fault remains after it has apparently been corrected the unit should be left switched off. The same applies also where the current overload in the control panel regularly trips, where the DI leakage sensor or the temperature sensors in the stator are activated. We recommend that in such cases you contact your local Sulzer Service Centre. 10.3... - Page 30 PERIOD OF TIME: Recommendation: once a year ACTIVITY: Checking of the tightening torques of the screws and nuts. DESCRIPTION: For safety reasons we recommend that all screws are checked for their perfect positioning once a year. MEASURE: Tighten screws with correct tightening torques (see Section 1.6).
