（6）The compressor can
’
t be used in the place with corrosive atmosphere such as hot
spring and chemical warehouse. It should not be the structure often splash water
on the
surface of the compressor forcibly.
（7） The trouble of cross valve, electromagnetic valve, defroster, refrigerant controller,
fan motor used in refrigerating system may cause compressor accident .So their
reliability should be ensured completely. Moreover, the way of design, manufacture,
application of refrigeration cycle with less-leak should be adopted.
（8）The main electric circuit should be equipped with fuse or breaker.
（9）Refrigerant should be charged from the end of condenser of refrigerating systems.
Never
charge refrigerant to the compressor directly.
The refrigerant should always be charged in liquid state. When the refrigerant is
charged in gas state. The percent component will possibly be changed.
(10) Temperatures within systems during stable compressor operation should not be less
than -35℃ to prevent wax precipitation from the oil.
(11) T
he units of refrigerating system should be connected to earth.
12）Compressor mounting
Rubber grommets are designed soft to provide the noise isolation and to lessen
vibration
Energy transmission.
Stud bolt should be designed to provide sufficient clearance for
noise andvibration
isolation and to prevent compressor from coming off its mount.
There should be adequate clearance between the under－surface of Push-Nut and the
upper surface of rubber grommets.
