1 Maintenance
#Warning!
Process pressure and temperature, contamination, electrical voltage
Danger! Risk of serious or fatal injury!
• De-energize the device before removing the rear panel.
• Power can be supplied to switching contacts from separate circuits. De-energize these circuits
before working on the terminals.
• If a sensor has to be removed during maintenance work, avoid hazards posed by pressure,
temperature and contamination.
"Caution!
Electrostatic discharge (ESD)
Risk of damaging the electronic components!
• For your own safety, only use genuine spare parts. With genuine parts, the function, accuracy
and reliability are also ensured after maintenance work.
• Take personal protective measures to avoid ESD.
1.1 Recommended maintenance
Maintenance work has to be carried out at regular intervals to ensure the efficient operation of
the sampler.
The maintenance work comprises:
• Replacing the wear parts
• Cleaning the device
The cleaning intervals depend heavily on:
• The medium
• The ambient conditions of the sampler (dust etc.)
• The programming intervals
For this reason, adapt the cleaning intervals to your specific requirements but always ensure that
these cleaning tasks are performed regularly.
Replacing wear parts
Wear parts are replaced by Endress+Hauser Service at one- and two-year intervals. Please
contact your local sales center in this regard.
Endress+Hauser offers its customers a maintenance contract. With a maintenance contract,
you can increase your level of operational safety and relieve your operating staff of some of
their workload. Ask your Endress+Hauser Service Organization for detailed information on
maintenance contracts.

1.2 Replacing the pump tube
#Warning!
Danger! Rotating parts!
• Take the sampler out of service before opening the peristaltic pump.
• Safeguard the sampler against accidental operation while working on the open peristaltic
pump.
Open the peristaltic pump as follows:
1. Take the sampler out of service by pausing a program that is currently running.
2. Open the fastening clip (item 3) and push the pump bracket (item 4) upwards.
3. Remove the knurled head screw (item 7) and open the pump head cover (item 5) to the
right.

1. Remove the clamp (item 8) and remove the pump tube (item 2) from the pump.
2. Remove any silicone deposits on the roller (item 10) and the flexible pump bracket.
3. Make sure the roller turns smoothly and evenly.
4. Apply some lubricant to the roller.
5. Secure the new pump tube to the pressure sensor with the clamp (item 8).
6. Guide the pump tube around the roller and insert the marking ring into the groove
(item 9), see →å2.
7. Close the pump head cover and screw it tight. Close the pump bracket.
8. Under Menu/Diagnostics/Term information/Pump tube life reset the tube life to zero by
selecting "Reset".
Calibrate the sample volume each time you replace a pump tube. --> See Operating
Instructions BA467C "Calibration".
"Caution!
Incorrect sample volume
Only reset the tube life counter to zero once you have successfully replaced the pump tube in
order to avoid incorrect dosing of the medium.

• Benzyl alcohol
• Methylene chloride
• Methanol
•Xylene
• Concentrated glycerol cleaner
• High-pressure steam
1.3.2 Wetted parts
After cleaning, rinse all wetted parts thoroughly with clear water to ensure that all cleaning
agent residue has been removed so it cannot affect subsequent medium samples.
