1-3．Precautions for Electrical Wiring (1) Earthing Cables Earthing cables should be connected. (2) Over Current Relay The compressor must be protected from over current by using the over current relay. The compressor must be protected to ensure that it will stop at the maximum allowable current or less stipulated in Clause 3 “General Specifications”... -
Page 28: Precautions When Storing And Transporting
1-4．PRECAUTIONS WHEN STORING AND TRANSPORTING (1) Storage *The compressor should be stored in a clean, dry place. *The compressor is a horizontal type. It should be transported and stored in a horizontal position. *Do not store the compressor outdoors or in a place where water-drops from the circumferences are poured on to the compressor. - Page 29 (3) Refrigerant Pipe Connection *The oil in this compressor is synthetic oil, and it has a higher moisture-absorbent than conventional oil. Do not leave the compressor with the suction and discharge pipes open to the air for a long period of time. As a guide, it should be limited to within 3 to 5 minutes. *To avoid the oxidation of pipes, brazing should be carried out while nitrogen flows into the brazing junction.
- Page 30 (8) Precautions When Charging Refrigerant Oil * Because the appropriate amount of refrigerant oil is charged in the compressor before shipping, no additional amount should be charged, in principle. *If you have no choice but to charge additional oil, you will need to meet the requirements for the relationships between refrigerant charged capacity and oil charged capacity prescribed in 1-5.(7).

Page 32: Control Sequence
2-1．CONTROL SEQUENCE The compressor is protected by OCR (overcurrent relay for compressor motor) and a DT (discharge gas thermostat). These safety devices are automatically reset. Therefore, all control circuits should be designed to guard against harmful on-off restarting by the installation of the automatic reset safety device. A typical control circuit for the scroll compressors is shown in Clause 2 “Basic Electrical Wiring Diagram (for 3 phase).”... -
