(2) Tap-water
piping
This is piping to supply cleaning water and zero-calibration water to the detector. Supply water
having a turbidity of 2 mg/l or less, such as tap water. The pressure of the water to be used is 100
to 500 kPa. Piping connections are designed for a rigid PVC pipe of nominal size VP16 (OD-22
mm). Do the piping using any
fi
ttings conforming to the pipe diameter similar to the piping for
sample.
Note: Please consider to install a check valve so that cleaning water does not
fl
ow backward
in the tap water side.
(3) Drain
piping
This is piping for draining the sample and tap water supplied to the detector to a drain or the like.
The piping connection is designed for a rigid PVC pipe of nominal size VP40.
Connect such a pipe of nominal size VP40 (VU40) or more and do the piping so that debris does
not remain or get trapped or get trapped in the pipe.

fi
ed,
refer to Figure 3.10.
