sample with the lowest expected phosphate concentration
to Stream 1.
Referring to Fig. 4.12:
1. Connect sample inlet tube to constant-head unit sample

A contaminated drain tube is supplied fitted to the analyzer. Cut
the tube to a suitable length at the free end to ensure it has no
kinks and is as short as possible. Keep the tube's cut end in free
space to eliminate the risk of air locks.
If an alternative contaminated drain tube is used, refer to
Fig. 4.13 and route contaminated drain tube

through centre channel

drain collector .
Note. Keep the contaminated drain tube as short as
possible and route it as vertically as possible to allow free
draining.
If samples are to be recycled, use separate drains for
contaminated and sample outlets.
