A shaft seal, which would be subjectto wear and maintenance is not required. Depending on the design of the pump, the system fluidlubricates the sleeve bearings and cools both bearings and motor. The pump is maintenance-free andrequires no further maintenance after the air bleeding procedure during the initial start-up (no afterstart-up maintenance).The Wilo model TOP-Z is specially designed for use in conjunction with drinking water circulation systems.Thanks to its design and materials used in its construction the pump is resistant to corrosionfrom elements in domestic hot water ( drinking water). All materials coming in contact with the deliverymedium are NSF/ANSI 61 certified.6.3 FunctionsSpeed setting of TOP-S.../TOP-Z... pumps (Fig. 5 and Fig.6)The required speed of the pump can be adjusted manually in 2 positions (Max. and Min.) by movingthe switch connector to the relevant socket. Procedure see Chapter “8.2 speed setting”.Ensure power is turned off prior to changing speeds!7 Installation and electrical connectionInstallation and electrical work in compliance with any local codes and by qualifiedpersonnel only!WARNING! Bodily injuryExisting regulations for the prevention of accidents must be observed.7.1 InstallationxThe pump must be installed in a dry, well ventilated and frost-free place.CAUTION! Possible damage of the pumpForeign materials such as dirt and solder can effect the pump operation.xIt is recommended that any welding and soldering work be done before installingthe pump.xThoroughly flush the system prior to installing and operating the pump.xForeign material in the system resulting from construction may damage the pumpand is not warrantable.xxThe pump must be installed in an easily accessible position to facilitate inspection or replacement.The pump should never be located at the lowest point of the piping system, where dirt and sedimentcollect. Nor should it be located at the highest point of the piping system, where air accumulates.Please ensure at least a minimum of three pipe diameters of straight on the suctionside of the pump.6WARNING! Electrical shock hazardDangers caused by electrical energy must be excluded.National Electrical Codes, local codes and regulations must be followed.
