aserviceunitisessentiallythesameasusingamanifoldandvacuumpump.句子中的“usingaserviceunit”是一个现在分词短语，用来修饰限定“Evacuation”，“usingamanifoldandvacuumpump”作用也是一样。全句可译为：维修设备的排放和歧管量表及真空泵的排放，效果是完全一样的。Grammarstructures语法结构Thesystemshouldbeoperatedtomakesurethattheoperatingpressurearecorrect,airdischargefromtheductsisacooltemperature,andthecompressoranddrivebeltsarerunningproperlyandquietly.“shouldbeoperated”被动语态按中国人的阅读习惯可译为“起动空调系统……”。“theoperatingpressure…”“airdischarge…”“thecompressor”并列作宾语从句。Text课文A/Csystemhavetwomajorparts:Thehighsidestartsatthecompressorandendsattheexpansiondevice.Thelowsidestartsattheexpansiondeviceandendsatthecompressor.空调系统可以分为两大部分：高压侧始于压缩机，结束于膨胀阀；低压侧始于膨胀阀，结束于压缩机。Text课文Notethatthemanifoldvalvesareopenorclosedasneeded.要注意的是，歧管量表装置的阀门的开闭由具体实际情况而定。Text课文Chargingfromalargecontainerwhileusingamanifoldrequiresameanstomeasuretherefrigerant.当用歧管量表装置从大容器向空调系统加注制冷剂时，得有一个计量制冷剂的办法。SafetyTips安全提示1.在加注时，应戴好防护手套，以免制冷剂滴到皮肤

上冻伤皮肤。2.空调的制冷剂不能直接排放到大气中，报废的制冷剂必须加以回收。3.空调系统机油含有被溶解的制冷剂，属于危险废弃物，必须送到指定的处理点进行处理或回收。
