Sampling The Deionized Water; Selecting The Water Quality Unit - Yamato Pure Line WL320A Instruction Manual

Sampling the deionized water

Note1: At initial power application and immediately after replacement of ion exchange resin
cartridge, a certain time period is required till sampling begins because of air remaining in
the ion exchange resin cartridge and piping.
Note2 : The pressure remains in the piping at a time of stopping sampling, which may discharge
small amount of deionized water.
