Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.

This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.

Good list of manuals. I found a very rare one and easily get. Should be promptly to download, as we must to wait hours even after confirmed payment.
Cycle Troubleshooting Guide
Trouble analysis
1. Check temperature difference between intake and discharge air and operating current. Temp. difference : approx. 0°C Current : less than 80% of rated current Temp. Difference Temp. difference : approx. 8°C Current : less than 80% of rated current � All amount of refrigerant leaked out. Check refrigeration cycle.
� Refrigerant leakege Clog of refrigeration cycle Defective compressor
Operating Current
Temp. difference : less than 8°C Current : over the reated current
� Excessive amount of refrigerant
Temp. difference : over 8°C
� Normal
Notice : Temperature difference between intake and discharge air depends on room air humidity. When the room air humidity is relativery higher, temperature difference is smaller. When the room air humidity is relatively lower temperature difference is larger. 2. Check temperature and pressure of refrigeration cycle. Suction pressure (Compared with the normal value) Temperature (Compared with the normal valve) High Higher Normal
Cause of Trouble Defective compressor Defective 4-way reverse valve Excessive amount of refrigerant Insufficient amount of refrigerant (Leakage) Clogging
Description Current is low. High pressure does not quickly rise at the beginning of operation. Current is low. Current is low.
Lower
Higher
Notice : 1. The suction pressure is usually 4.5~6.0 kg/cm2G(Cooling) at normal condition. 2. The temperature can be measured by attaching the thermometer to the low pressure tubing and wrap it with putty.
