Maintenance

7.1

Maintenance intervals

regularly

•

Sample water monitoring (chapter 3.5.7)

•

Circulation monitoring (chapter 3.5.7)

daily

•

Check the flow cell, including all screw
connections, for leakage

weekly

•

Check the electrode cleaning sand

every six months

•

Replace the electrode cleaning sand

as required

•

Clean or replace optional strainer

every 4 to 6 weeks or local standards

•

Check ORP (Redox) sensor in calibration
solution (instruction manual sensor)

•

Check conductivity measurement with
comparative measurement and/or cali-
bration solution (instruction manual sen-
sor)

in accordance with standard or local
regulations

•

Comparative measurement of chlorine
and pH, if necessary calibration

5 years

•

Replace battery of the electronics module

•

Replace battery of the Impedance conver-
ter

7.2

Maintenance parts set

7.3

Checking for leakage

Check the entire flow cell every day, including
all screw connections, for leakage. Repair any
leaks immediately.

7.4

Checking and replacing the
electrode cleaning sand

The electrode cleaning sand is necessary for
cleaning the chlorine sensor and must be
replenished or replaced if necessary. The elec-
trode cleaning sand must be checked and
replaced regularly (chapter 5.11). Grinds itself
down with time. Check the flow cell at weekly
intervals to make sure that there is enough
electrode cleaning sand in the cell body. The
electrode cleaning sand must be swirled
around in the bottom part of the cell body.

DANGER

Risk of injury or death!

External voltages may still be connected

even if the operating voltage is switched off.

NOTICE

Liability for defects can only be accepted if
maintenance work is performed as speci-
fied. Adhere to the applicable standards and
national and regional regulations.

Part no.

NOTICE

Ascending air bubbles in the cell body influ-
ence the measuring accuracy. The cause
must be determined and remedied.

NOTICE

After adding fresh electrode cleaning sand
or replacing it, the electrode current can
increase slightly for approximately 2 to 3
hours. Calibration is needed after this (chap-
ter 6.6).
