3. Disconnect fluid connections (2) to and from the reactor (4).
A small amount of water can escape here (residual liquid in the reactor).
4. Release the connecting plug (1) to the electronic ballast.
5. Remove the reactor from the holders of the metal housing. For this purpose, the
reactor must first be removed from the top holder (3) and then from the bottom
holder (5).
Please ensure that the glass ends of both the old and new reactor are not
touched.
6. Insert the new reactor into the system. Here, the reactor must first be inserted into
the bottom holder and then into the top holder.
When inserting the reactor, care must be taken to ensure the electronic cables to
the plug are not damaged and that they are inserted behind the reactor in the
groove provided for this purpose.
7. Reestablish the electronic connection to the electronic ballast and the fluid
connections.
8. Restart the system.
The system mode checks the reactor to ensure it is functioning correctly without
any errors.
9. On completion of the check, reset the operating time counter of the reactor.
This completes the installation of the new reactor.
Following a reactor replacement, the new reactor must run in system mode for at
least 20 minutes at normal pump speed and with the lamp switched on. This removes
any impurities and contamination. In addition, it is also essential to calibrate the new
UV reactor.

‣
Before you release any hoses, make sure that no actions, such as the pumping of
sample, are currently running or are due to start shortly.
‣
Wear protective clothing, goggles and gloves or take other suitable measures to protect
yourself.
‣
Wipe up any spilt reagent with a disposable tissue and rinse with clear water. Then dry
the cleaned areas with a cloth.
NOTICE
Do not operate the analyzer for longer than 3 days without taking it out of service
properly!
Can result in damage to the device.
‣
Take the analyzer out of service as described.
To take out of service, proceed as follows:
1. Stop the flow of sample entirely.
2. Rinse the analyzer with ultrapure water.
3. Empty the hoses entirely.
4. Seal the connection caps with dummy plugs.
5. Fit blind plugs on all the inputs and outputs.
