Operation Manual

Section One BriefingsXG2.SH manual door EO sterilizer is the latest model completed in our

company, on which a modern device---pro ramma!le controller is

e"uipped, renderin it a multitude o# #unctions hi h relia!ility and

convenient operation. On this model also adopted a touch screen as an

inter#ace !etween the operator and the machine, which can satis#y the

customers with a visual and easy operation. $his model is more suita!le

#or control at spot and a!le to #ul#ill the customers% re"uirements !ymodi#yin the so#tware in &' and the pictures on the touch screen.

Ethylene o(ide as is ta)en as sterilization medium, which can )ill all

)inds o# micro!e virus sporan ium !acillus and propa ator with its

stron penetra!ility !road-spectrum. Ethylene o(ide as can per#orm its

#unction under lower temperature without dama e to the materials

sterilized. So it is widely used in medical sanitary trade units and

!an) archeolo y archive and culture relic departments, and appears its

special advanta es in sterilization #or those with #ear o# heat humidity

and erosion.

A. Health and safety information

Read this manual carefully before use. Pure EO, as the

medium for this series of sterilizer, is inflammable and explosive. So

operators must be trained before going at the equipment.
