substance(s). If using a sample inlet unit, use caution when disconnecting the
CM-800α unit.

CAUTION
◇Cleaning liquids up to 150℃ can be used for CIP or SIP. The cleaning liquid can
be used safely for 30 minutes at one time. The momentary difference between
the sample liquid temperature and the cleaning liquid temperature must be no
more than 80℃.
When using cleaning liquids at temperatures over 150℃, the power source
(DC24V) must be turned off. If the AD-32 (AD-33 or AD-34) is used, unplug from
the outlet before cleaning.
①Detach the clamp band that connects the main unit to the sample inlet unit, piping or tank.
②Clean the prism surface carefully with a
soft tissue soaked with warm water or
ethyl alcohol. If the sample solution
contains oil or grease, use ethyl alcohol
to ensure the prism surface does not
develop a film.
Development of a film on the prism could
cause erroneous measurements.
③NEVER clean the prism with an abrasive
material.
Cleaning the prism with an abrasive
material could cause scratches on the
prism which could lead to erroneous
measurements.
④After cleaning is complete, re-attach the
CM-800α unit to the sample inlet unit,
piping or tank.
The procedure is described on page 14 of
this instruction manual.
