Theseoperating Instructions should be read andunderstood by the engineer, as well as otherresponsible operators before assembly andoperation.

4 Operating Instructions shouldalways be readily available wherever themachine is being general safety rules detailed under SafetyPrecautions , plus the safety precautions set bythe end user, must be Relating to Safety Precautions in the Operating InstructionsPersonal injury, damage to machines or con-tamination of the environment can result if thesafety precautions contained in this documentare not strictly enforced. Following are signscommonly used to signify areas of danger:Safety Sign Danger to General PublicSafety SignElectrical HazardDanger from Possible Injury by MachineryDanger from Suspended LoadsDamage to MachineryContinued on Page SAFETY PRECAUTIONSW arning or indication plates attached to thepump which show the correct direction of rota-tion (or fluid connections) must always be keptin readable and Training of PersonnelAll personnel responsible for service, mainte-nance, inspection, installation and operationmust have the appropriate and supervision of personnelmust be strictly enforced by the end user.

5 Iftraining of personnel is required, it can beprovided by the , it is the responsibility of the enduser to ensure that personnel fully understandsthe Operating of Safety PrecautionsNon-observance of the safety rules can result inpersonal injury, damage to machines or con-tamination of the environment. Non-obser-vance can void product can also result in the following: Premature failure of components or machine/equipment malfunction. Danger to personnel from electrical, mechanical or chemical hazards. Danger to the environment from leakage of dangerous OperationThe safety precautions outlined in these oper-ating Instructions , the existing national regula-tions on accident prevention and the end user sown Operating and safety regulations must Precautions Hot or cold machine components must be insulated or shielded.

6 Guards covering moving parts ( shafts, couplings) must not be removed while machines are in operation. Leakage of dangerous materials ( explo-sives, toxins or hot materials) from the shaftsealing area should be properly contained. In order to prevent electrical hazards, appli-cable local and/or federal regulations mustbe adhered to. Continued on Page Precautions for Maintenance , Inspection and Installation WorkThe end user must ensure that all Maintenance ,inspection and installation work is performedby authorized and qualified personnel whounderstand the Operating Instructions and areproperly on a pump/machine should only beperformed when it is disconnected from itspower source, pressure has been relieved, andthe complete unit has returned to roomtemperature.

7 It is imperative that theseprocedures are adhered to before attemptingwork on the or units which transfer dangeroussubstances must be following Maintenance work, allsafety and protection equipment must be re-installed and safety trips must be to Section , Start-up, before restart-ing Use of Spare Parts and/or Modifications to the PumpModifications to the machines and/or its com-ponents are permitted only with the manufac-turer s consent. Original spare parts and acces-sories authorized by the manufacturer ensuresafety. The use of other components revokesany warranty and liability for consequenceswhich may ApplicationMachinery is only guaranteed safe for the machinery was manufactured inaccordance to the specifications and theconditions specified by the end user.

8 Themachine should not be operated in any waythat exceeds design Points for the Use of NEMO PumpsNEMO Pumps should only be used for theapplication for which they were you wish to change the pumping medium,you should check with either the supplier ormanufacturer to ensure that the pump will besuitable for the new medium. This is especiallyimportant with aggressive, poisonous orotherwise dangerous for the selection of a pump between the medium to bepumped and the materials of all wetted pump between elastomeric components and mechanical seal pressure and temperature rating of the Pumps are of positive displacementprogressing cavity design, and have thepotential to generate very high on Page SAFETY SAFETY PRECAUTIONSA blockage or closure of a valve in thedischarge line can cause a pressure rise higherthan the installation can pressure increase can result in thebursting of pipes and/or damage to othercomponents of pump or drive caution must be used.

9 Especially whendangerous media is safety equipment must be installed( : an emergency stop button, a pressurerelief valve or rupture disc).During Maintenance and repair work on thepump, please note the following:1. No one other than those involved with Maintenance and repair should have access to power When dismantling the pump, follow the Instructions for handling the medium ( : protective clothing, no smoking, etc.)3. Before putting the pump back into operation, ensure that all guards and other safety devices ( : drive belt and coupling protection) are properly keep safety in mind during operation, Maintenance and install-ation of equipment.
