Installation
Installing the apparatus
-We recommend to install the apparatus as close to the sampling point as possible. If installed outside, the device should be positioned on a solid flat surface.
-The hose has to be laid with a constant fall from the sampler to the sampling point as lower lying points can lead to deposits in the hose which may freeze in winter or result in crosscontaminations.
-To fix the suction hose, we recommend to use the extraction unit available as accessory.
-Immerse the end of the hose at the sampling point with the open end facing downstream (direction of flow) so that coarse matter and fibres cannot be forced into the suction aperture
Mains connection / external power supply
A battery charger (option) is available to charge the battery.
Mains powered float charge option
The integral storage battery can be charged by means of the mains powered battery charger. In case of a higher energy demand, the battery charger can be permanently connected to the mains, so that the integral storage battery of the sampler is left permanently on charge (float charge).
Integral storage battery
A fully charged battery will, under ideal conditions, be sufficient for up to 2000 sample extractions.
Charging the storage battery
The integral battery is a maintenance-free sealed lead-acid battery. Charge the storage battery for at least 14 -16 hours prior to the first use.
This charging time is also necessary if the storage battery is empty. To avoid a total discharge, a protective mechanism is built-in which automatically switches off the device when the voltage is too low.
The storage battery cannot be overcharged as the battery charger switches to compensation charge as soon as the battery is fully charged.
For longer periods of non-use, top up the charge regularly (connect the battery to the charger). In any case, avoid a total discharge as otherwise the storage battery will be damaged.
Switch on / off
The device is switched on and off by the ON / OFF switch.
Option: mains operation. In case of exclusive mains operation, the device is switched on by means of the mains plug of the battery charger.
Hose connection
The inlet hose is connected at the side of the housing upper part (screw thread ¾“).
Signal connections
The signal connector (e.g. for a flow meter) is in front of the control.
Connection to a PC
The sampler is connected to a PC by means of an interface cable (art. No. BM900021) which is connected to the RS232 connector.

Troubleshooting - general
If a fault develops in your sampler, we can only provide prompt assistance if you give us the type and serial number of the apparatus concerned. You will find these data on the type plate.
The more precise your description of the fault is, the better our fault diagnosis will be.

Event signal
Eventproportional
A sample is extracted in fixed time intervals (e.g. every 10 minutes) with a fixed sample volume (e.g. 50 ml).
A sample is extracted in variable time intervals (depending on the flow (Q)) with a fixed sample volume.
The sampler is waiting for an event (e.g. the exceeding of a pH limit value). A sample is extracted in fixed time intervals (e.g. every 10 minutes) with a fixed volume (e.g. 50 ml) as long as an event is present.

5.Volume control tube
6.Metering vessel
7.Silicone discharge tube
8.Motor-driven pinch-valve
9.Air connection
Cleaning:
-Glass metering vessel: unscrew the screw cap (3) and remove the flange. Now, the metering vessel together with the silicone discharge tube (7) can be detached.
-Plastic metering vessel: Turn the plastic metering vessel anticlockwise (bayonet fitting) and remove.
Adjustment of sample shot volume at samplers with glass metering vessel:
To adjust the desired sample volume, loosen the knurled screw and displace the volume control tube vertically.
Adjustment of sample shot volume at samplers with plastic metering vessel: The sampler is always delivered with the volume control tube in full length. To adjust the sample shot volume, the volume control tube (5) has to be cut to length.
Procedure
1.There is a graduation in millilitres on the volume control tube.
2.Remove the metering vessel (6).
3.Cut the volume control tube to the desired length with scissors or a knife.
4.Reinstall the metering vessel (6) and tighten.
5.Check the sample volume by starting a manual sample extraction.
6.Now the device is ready for operation.
Remark: If you need to work with different sample volumes, you can cut to size several tube pieces. As the volume control tube (5) is only slipped on the hose connector (1), it is very easy to change the tube.

Replacement of the silicone discharge hose
The silicone hose (BM69301) is only pushed over the lip of the metering vessel. A hose clamp is not required. Humidify the hose a little bit, fix it at one point and push it over the lip.
Remark:
Do only use original spare parts from the manufacturer. The use of a wrong hose type can lead to malfunctions at the system or may even damage the pinch valve!
Remark:
Conductivity of the sample medium
There are two conductive level electrodes in the metering vessel. Their sensitivity can be adjusted in the service menu. In the factory the electrodes are adjusted to tap water (this adjustment does not have to be changed under normal operating conditions). Minimum conductivity 50 μS/cm.
Please note that a wrong adjustment can lead to a flooding of the pneumatic system and to the damage of component parts.
The sampler is not suitable for extraction of distilled water due to low conductivity.
Conductivity at 25°C
Rain water 50 μS/cm
Drinking water 500 μS/cm
Waste water 5000 μS/cm (5 mS/cm)
