Caution!
You may not carry out any procedures
not listed in the following chapters yourself.
This work may only be carried out by Service.
7.1 Maintenance schedule
All the maintenance tasks that have to be carried out during normal operation of the analyzer are
explained below. If you are using a sample conditioning unit, e.g. CAT430, coordinate the
maintenance work required for it with that of the analyzer. For this, read the maintenance chapter
in the Operating Instructions in question.
!
Note!
Prior to working on the reagent hoses, the hoses must be disconnected from the canisters in order
to prevent contamination of the reagents.
7.2 Replacing reagents
#
Warning!
• There is a danger of crushing at the door and pump heads.
• Refer to the warning instructions in the safety data sheets when handling reagents. Wear
protective clothing, gloves and goggles.
• Make sure the workplace is well ventilated when you work with chlorine bleach and/or
ammonia. If you feel unwell, consult a physician immediately.
• If reagents come into contact with the skin or eyes, carefully rinse with copious amounts of water
and consult a physician immediately.
• Never add water to reagents. Reagents containing acids may splash and heat may build up.
If you store the reagents correctly (in the dark, not over 20
°
C) they will keep (unopened) for a
minimum of 12 weeks from the date of production (batch number). When this period of time has
expired, the reagents must be checked and replaced where necessary. A cool, dark storage area is
required to achieve the maximum shelf life.
The reagents must be replaced when:
• The reagents have been contaminated by sample (see "Troubleshooting instructions")
• The reagents are too old
• The reagents have been spoilt by incorrect storage conditions or environmental influences.
Period of time Task Note
Weekly – Check and note down the calibration factor
(for service purposes)
– Move the valve hoses and spray with silicon
spray (extends the operating time).
CONFIGURATION
Monthly – Flush sample line hose system with
pressurized water (disposable injector),
check and
replace reagents if necessary.
– Spray pump hoses and roller heads with
silicone spray
– Check sample collector for fouling and clean
it if necessary
– see chapter "Replacing reagents"
– You must release the box of the sample
pump.
– Connect the disposable injector instead of
the sample supply.
