Hitachi CHROMASTER 5160 Instruction Manual page 104

NOTE: When unsuitable reagents absolutely necessary for
ingredient separation or reaction of a constituent have
been used, or when mobile phase which deposits salt
has been used, wash all the flow paths with distilled
water after completing analysis without fail. If not, the
plunger may wear down. Especially, pour water into
the rear part of pump head to wash it out.
Plunger Cleaning Mechanism (option) is separately
prepared. It is recommended to use this option.
Refer to 3.1.9 Wash after operation for details.
NOTE: When the suction valve and the discharge valve on the
pump head side are dried, mobile phase suctioning may
not be performed in early stage of the pump starting.
In such case, suck the mobile phase using an attached
syringe, and discharge it to the discharge valve from
the suction valve.
