IMPORTANT NOTICE TO USE THE COMPRESSOR PROPERLY, CAREFULLY READ AND FULLY UNDERSTAND THIS MANUAL. CAUTIONARY INSTRUCTIONS IMPORTANT READ THESE “CAUTIONARY INSTRUCTIONS” CAREFULLY BEFORE USING THE COMPRESSOR. 1. INSTALLATION WARNING ** TO AVOID ELECTRICAL SHOCK AND FIRE** Use this compressor on an earthed system only. WARNING ** TO AVOID LEAKAGE OF ELECTRICITY ** Be sure to use an ELB (Earth Leakage Breaker).
Page 21
WARNING ** TO AVOID EXPLOSION AND FIRE CAUSED BY CHARGING AND MIXING DIFFERENT TYPES OF REFRIGERANTS OTHER THAN THE SPECIFIED ONE ** DO NOT charge or mix different types of refrigerants other than the specified one in the cycle. ・Be sure to use nitrogen gas during the leakage test and the airtightness test. ・Ensure that you use the refrigerant pipes at the time of installation before operating the compressor.
1.RANGE OF APPLICATION AND PRECAUTIONS FOR USE 1-1.RANGE OF APPLICATION (1) Introduction *This compressor shall be used according to the specifications and specified conditions described in this engineering manual, and it shall not be used based on other specifications. Optional parts shall also be used as specified, and specified parts shall be used for service as well.
Page 23
(10) Temperature of Terminal Plugs The temperature of the terminal plugs should be below 150℃ to ensure safety in all operating conditions. (11) Liquid back to the Compressor Refrigerants to return to the compressor should be superheated in all operating conditions. Liquid return to the compressor is prohibited.
1-2.PRECAUTIONS FOR REFRIGERANT CYCLE DESIGN (1) Oil Return and Oil Quantity *The refrigerant cycle should be so designed that the oil return to the compressor should always be secured, and oil should not accumulate. *The compressor should be operated by keeping the shaft horizontal, but in reality the compressor should be operated with a maximum of 5.6 degrees (9.8%) inclination in all directions.

(3) Safety Device for Protection from High Pressure and Low Pressure *Be sure to use a high-pressure switch or safety valve. *Be sure to use a low-pressure cut switch. *Considering the tolerance of the pressure switch, the device should be set to values so that it can be within the operation pressure limits stipulated in Clause 6 “Working Range (Pressure and Temperature)”...
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”...
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).
2. BASIC ELECTRICAL WIRING DIAGRAM (for 3 phase) The following electrical wiring diagram shows a typical example of protection designs. The electrical circuits to protect the compressor should be designed in consideration of system designs and the actual usage state. Power Supply:3φ...
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).”...
(7) The power lines from the terminal box should not contact the surface of the compressor. If they come into contact with it, the power lines will be damaged. (8) The gasket is installed in the terminal box. The procedures for removing and re-installing the plug cover are as follows: *Removing the Cover When the gasket sticks out on the terminal box side and the cover side respectively and the...
