Maintenance and Service
To ensure long and trouble-free operation of the analyser, maintenance must be carried out on the
unit at regular intervals. Make sure that the unit is switched off before maintenance work is carried
out. No analyses are carried out during this time. As a general rule, wear protective goggles and
gloves during maintenance to avoid contact with reagent, cleaning fluid or other liquids.
The following maintenance intervals must be observed:

temperatures or water with a high organic load, the cleaning
intervals must be shortened if necessary.

Cleaning the measuring chamber
Cleaning the measuring chamber takes about 20 minutes. To clean the measuring chamber, proceed
as follows:
•
Switch off the unit.
•
Pull the hose pump cassette from the holder by unlocking it at the clips at the top and
bottom.
•
Disconnect the reagent plug and the reagent bottle.
•
Pull the locking pins slightly forwards. (The locking pins can only be pulled up and not out).
•
Pull the drain plug, actuator plug and inlet plug out of the measuring chamber.
•
Pull the measuring chamber to the right off the retaining bolts on the control unit housing.
•
Remove the stirring blade
•
Lever the reagent plug upwards with a flat-blade screwdriver. (Make sure that the locking
pins are pulled up before levering).
•
Clean the measuring chamber and the plugs using the SYCON Clean cleaning set as
described on the instruction leaflet.
For trouble-free operation, it is important to clean not only the measuring
chamber but also the actuator plug with the white (LED). Take a cloth and
moisten it with FIT3000 (included in the SYCON Clean Set) and wipe the
actuator plug thoroughly.
When assembling, please be sure to observe the following sequence:
•
Lubricate O-rings (3 x J and 1 x C) with technical Vaseline. See picture spare parts on
Page 75.
The blue dosing O-ring (D) on the reagent plug must not be lubricated with
technical Vaseline.
On the other hand, the black O-rings (3 x J and 1 x C) must be lubricated with
technical Vaseline before insertion into the measuring chamber.
