I ordered this manual sometime in the afternoon and I received it on my e-mail the same evening.
This is a fantastically good and properly scanned copy of the original manual. All pages are of the same scale and they overlap each other. It means that you can print the manual and easily make it as a convenient paper manual.
The content of the manual is fantastic. Alignment descriptions, PCB layouts and elementary diagrams are explicit and precise. I immediately found what I was looking for. Thanks to this manual and Owner-Manuals.com my amplifier is alive again. Many thanx indded!
Troubleshooting
5-3-10 (N) Check of instantaneous over-current protection of IPM circuit.
Inverter instantaneous over-current protection mode is the mode to be actuated in order to prevent the damage of elements from the peak current of IPM circuit elements. In case that the inverter circuit instantaneous over-current protection mode actuates.
(condition of installation)
�The ventilation is not good because the outdoor unit is installed wrong (the ambient temperature is higher than 50 (°C) ) -> Reinstall the outdoor unit so that the good ventilation can be made. �In case that the operation is made with the cover bent of the outdoor unit. -> Take out the cover. �If two outdoor units are operating face to face, (the bad ventilation is made) -> Reinstall the outdoor unit for the good ventilation. �The air circulation is bad due to the attachment of falling leaves. -> Take away the leaves for the good ventilation. �If the Refrigerant is overcharged. -> Check the amount of Refrigerant.
(Unit defect)
�If the comp is locked. -> Replace the comp. �If the comp is operating without the revolution of fan motor. -> Check the fan motor connector and replace the fan motor. �In case the parts of the control board is damaged. -> Replace simultaneously the inverter control board and the IPM board.
5-3-11 (O) Check of the comp discharge gas temperature and OLP temperature abnormal rise.
If the comp discharge gas temperature and OLP temperature rises higher than a certain level, it protects the circuit. If the comp discharge gas temperature and OLP temperature rises abnormally,
