Installation instructions
To install the analyzer at the intended location, proceed as follows:
1.
Place the analyzer in position and secure it. For the installation dimensions, please
!
see chapter 3.2.
Note!
A wall bracket is available as an option for mounting the analyzer ( → Chap. 8
"Accessories").
2.
Lay the drain pipe for the reaction products. Where possible, use fixed pipes (PVC
or PE, internal diameter ¾ " with 3% incline).
!
3.
Connect the sample transfer.
Note!
The sample can be obtained as follows:
– Directly or after a reversible flow filter or a cross current filter by means of a small
pump (rating approx. 300 ml/min), suitable for clear media, e.g. in the discharge
channel of a sewage treatment plant
– From a sedimentation tank or after microfiltration; this is practical for media
containing flocculants,
e.g. in an activated sludge basin
– Sample conditioning using ultrafiltration for heavily soiled media,
e.g. from the primary settling tank.
For questions regarding sample conditioning and its automation, please contact
Endress+Hauser Service or the Endress+Hauser Sales Centre responsible for your
region.
4.
Connect the tubes from canisters containing reagents, standard and cleaning
agents to the following nozzles:

Reagent 2
Reagent 3
Standard
Cleaning agent
5.
Tighten the pump hoses onto the sample pump and onto the reagent pump.
Set the pressure at the hose bed throttle valve ( → Fig. 9, P. 35, item D) such that
6.
sample and reagent are fed in without bubbles.
This completes the installation process. Now carry out the installation check and
proceed according to chapters 4 ("Wiring"), 5 ("Operation") and 6 ("Commissioning").

Post-installation check
• After mounting, check that all connections are secure and leak-tight.
