SURDIAL is given by this Trouble Shooting Manual. All operations described in this
Manual should be performed by only qualified serviceman or technician who should be
familiar with replacement of components of microprocessor based electronic devices and
should have basic knowledge concerning conventional dialysate line of dialysis machine.
The serviceman or technician should be familiar with all operations contained in this
Manual by reading it thoroughly to full understand them before starting trouble shooting.
Use this Manual together with Operation and Service Manuals of SURDIAL. Same
descriptions contained in them are minimal.
Generally, information required to operate SURDIAL is contained in Operation Manual of
SURDIAL though technical description is also contained partially. Information related to
maintenance, component replacement and various settings is contained in Service Manual
of SURDIAL. In this Manual, information related to method of trouble shooting is
contained.
Description concerning the trouble shooting contained in this Manual is protected by
