| Caution |
| GLDSeries,compared with G Series, is markedly upgraded. Forthesakeofhaving the maximum performance, in addition to notesforGseries,be careful of also the followings. | | 1. | GLDseriesiscapable of reaching to a high vacuumarea(10-2 Pa). Flanges,vesselsusable at a high vacuumare required. | | 2. | Anoil-sealed rotary pump is not recommendedforcontinuousoperationnear atmospheric pressure. |
