| Caution |
| GLDSeries,compared with G Series, is markedly upgraded. For thesakeofhaving the maximum performance, in addition to notes forGseries,be careful of also the followings. | | 1. | GLDseriesiscapable of reaching to a high vacuum area (10-2 Pa). Flanges, vessels usable at a high vacuumarerequired. | | 2. | Anoil-sealed rotary pump is not recommended forcontinuousoperationnear atmospheric pressure. |
