12. Compressor should be stored in a dry and drafty place
13. Compressor should not be tilted or inverted in storage, transportation and installation; Collision should be avoided.
14. Rubber plugs should not be pulled out from discharge tube before installation so as to avoid impurity and humidity. During the installation, the rubber plugs of discharge tube should be pulled out at first, then the rubber plugs of process tube, and the rubber plugs of process suction tube at last. The installation should be completed within 10 min after that.
15. The compressor's ground connection should be reliably connected with that of the refrigeration appliance all the time.
16. In order to keep a pressure balance in system, the interval of operation should not be less than 5 min.
17. The charging volume of refrigerant oil has been optimized by our company. Don't pour any oil out or into to the compressor randomly.
18. The stocking period must be less than 6 months after the date of production. If longer, you have to check whether the filled dry nitrogen is sufficient. Replenishment must be done if necessary.
