Installation
21
Reagent and
filter connections
Install the air filter.
Install the reagent bottle.
We recommend to use DIPA to operate the instrument. Use a
reagent bottle with either G45 thread (Schott) or a bottle from Merck
using a thread adapter. Close the bottle well to prevent the forma
-
tion of reagent vapors. For installation see
If the automatic regeneration module is installed:
Screw a bottle of SWAN regeneration solution to the holder and fill
the tube with regeneration solution by calling the <Maintenance>/
<Regenerations>/<Manual Operation> menu item.
Instrument setup
Program all parameters for external devices (interface, recorders,
etc.). Program all parameters for instrument operation (limits,
alarms, measuring interval).
Run-in period
Let the instrument run continuously for 1 h.
Calibrate pH
See
pH Process Calibration, p. 43.
Calibration of
sodium electrode
Rinse the standard bottles well with deionized water. Prepare the
sodium standards directly in the graduated standard bottles using a
precision pipette. Make sure the concentrations are programmed
correctly.
Etch the sodium electrode and then perform a two-point calibration.
