The 20µ filter removes the last impurities from the demineralized water and thus
protects the downstream equipment from possible damage.
To measure the conductivity, DM water can be extracted over the sampling tap. To
do this, hold a clean container under the tap and rotate it in counter-clockwise
direction. Flush the container out first with DM water to remove any impurities that
could lead to measuring errors. Then extract approximately ¼ l of DM water and
close the sampling tap by rotating it in clockwise direction until it stops. With a
calibrated conductivity gauge the conductivity of the DM water can now be
determined. The value should be < 0.5 µS. When the values are around 1 µS, the
synthesizer cartridge should be replaced soon.
ATTENTION:
Values > 2-3 µS are definitely too high! In this case, NORTEC Customer Service
should be notified!
For help selecting a suitable conductivity gauge, please contact our Customer
Service department. Our specialists will be happy to assist you.
3.4 Functional description of the additive
The CO
2
bottle is connected to the SynPur over a hose. For this connection the
hose should be routed through the cable sleeve of the mounting rail (see diagram
in Section 4.2, Point 7) and connected to the support console. The SynPur feeds
CO
2
to the demineralized water.
The gas fitting should be connected to the CO
2 bottle
and the valve on the bottle
opened. The bottle pressure is indicated on the left pressure gage of the gas fitting.
The pressure of 6 bar (87psi) can be adjusted over the pressure reducer (can be
read on the right pressure gage). The valve can then be opened on the gas fitting.
