1 Introduction
The AAO100 dosing pump is used to introduce a cleaning
solution to the jetwash of an AP200 pH system at preset
intervals. The timing, duration and amount of cleaning is
controlled by the AX400 pH analyzer.
The AP200 jetwash system enables automatic cleaning of both
the measuring element and the reference junction by spraying
water or a cleaning solution at them in situ, thus reducing
system maintenance requirements.
2 Installation
2.1 Fitting the Pump to the Reservoir
Referring to Fig. 2.1, secure the pump to the reservoir using the
two screws Aprovided.
