A Flash Card is used to input the operating program
into the chiller IPU. A Flash Card is used instead of
an EPROM. Normally, a Flash Card update is not re-
quired and the message above will be displayed.
If the operating software is to be updated, insert the
Flash Card into the Flash Card input port. Turn off the
Unit Switch and set the FLASH CARD UPDATE TO
"ENABLED" using the ↑ and ↓ keys.

If the update resulted in an error, the original program
will still be active. When an error occurs, assure the

ware will cause an error. If this is not the case, the
Flash Card is most likely defective or the IPU and I/O
combo board is bad.
