*1The notion is followed by the UL regulation. 1 HP (horse power)=745.6999W *2Other materials are available. Technical Notes
1. Since the VL15-U is approved as the complete assembly, any modification, disassembly, or replacement of parts on site is impossible. Return the VL to NOHKEN for repair and/or replacement. 2. For top mounting in high silo in a hazardous area, use the VL522N or VL522F approved d2G4 by T.I.I.S.,Japan.
