Note: For optimal performance, the minimum rinse water pressure should be 2.5 bar.
Install the dilution assembly as follows (the numbers in brackets refer to
Figure 13
):
1.
Install the control valve on the panel (position 4 in
Figure 10
on page 37).
2.
Remove the overflow pipe (position 8 in
Figure 4
on page 10) and install the dilution
assembly (13) in its place in the measurement cell using the Teflon washer and O-
ring.
3.
Install the PE tubing 3.2/6.4 (14) between the control valve (12) and output A of the
dilution reservoir.
4.
Install the PE tubing 3.2/6.4 (15) between the control valve (12) and output B of the
dilution reservoir.
5.
Connect the cable (16) to terminals 6 and 7 of J14 in the electronic unit (refer also to
Figure 8
on page 18 and
Table 6
on page 20).
6.
Connect the compressed air between the outlet (19) and inlet (20) connections.
7.
Adjust the opening and closing pressures of the system using the adjustment screw
(17). The system should close as slowly as possible.
8.
Connect the sample to the input (10) with 12 mm internal diameter tubing (pressure
0.5 - 6 bar)
9.
Connect the rinse water to the input (11) with 6 mm internal diameter tubing (pressure
2.5 - 6 bar)
10.
Connect input P on the T connection (18) to the compressed air supply (pressure 4 -
7 bar)
