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.
