Installation Area

• The installation area should be free of sources of vibration and electromagnetic interference that could affect the proper functioning of the printer.
• The floor gradient should be less than 0.5% (5 mm per meter).
• The floor should be stable and able to bear the load of the printer. The minimum floor load is 607 kg/m2 (125 lb/ft2 ).
• Clearance around and above the printer should ensure convenient access and servicing.
• The printer has not been designed to meet water-ingress protection standards, nor is it recommended for the printer to be in an area where there is a high relative humidity (see “Environmental Conditions” on page 16). Therefore, Stratasys recommends a distance of approximately 5 m between the printer and any source of water (such as a cleaning station). However, it is the customer’s responsibility to ensure that this distance meets all local and/or regulatory requirements governing water-ingress protection and water-related electrocution hazards. Consult with an expert, as necessary.
• Shelves and cabinets are recommended near the printer for convenient storage of tools, parts, accessories, manuals, and materials.
