日立变频压缩机使用注意事项

1.设置排气单向阀可以起到能量调节与压缩机不带压差启动；
The exhaust check valve may adjust capacity ,and startup at no pressure difference.

2.每台压缩机都需要独立设置电流、压力、温度等保护装置；
Some protected device should be mounted for any compressor ,for instance current, pressure and temperature.

3.在系统匹配时需要考虑在各种运行模式如：高落差长配管、最大注氟量等情况下的回油状况，当压缩机出厂注油量（1800ml）不能够保证压缩机运行的最低油量400ml时可以从压缩机排气侧补充适量牌号为SUNISO 4GDI-HT的冷冻机油。
It should be given our attention to oil that compressor runs for example long tube and the max. refrigerant. If compressor oil fall short of 400ml,it must be injected from the exhaust.

4.压缩机在去除吸、排气接头盖后，请勿放置10分钟以上；
Installation shall be completed within 10 minutes after removing the caps of suction and discharge tube.

5.请勿压缩空气；
Do not compress air.

6.在真空状态下请勿通电；
Do not energize under vacuumed condition.

7.在环境温度低于20℃时，必须安装油加热器（40～80W,220V）；
Crankcase heater is require if ambient temp. is below 20℃.

8.请勿反向旋转；
Do not reverse rotate.

9.运转时，各相间的电压偏差应在额定电压的3％以内；
Voltage (run):Voltage deviation each phase shall be within 3% of the rated voltage.

10.成箱压缩机包装件的叠放堆码极限为2箱,装卸过程中严禁翻滚；
Pile limits 2 pallet.Tumbling is forbidden during handling.

11.向压缩机充油或冷媒时，必须从排气侧进行；
Charge oil or refrigerant from the discharge pipe.

12.压缩机的接地装置应永久与制冷器具的接地装置连接；
The compressor’s ground should be connected with that of refrigeration system permanently and firmly.
