document within easy reach near the device for consulting in case of doubt.
2 Safety
2.1 Intended Use
The device is a low flow rate gas sampling pump for combination with residual oxygen measuring devices
for protective gas applications.
The device must be used only according to its intended purpose and under suitable conditions.
The manufacturer will assume no liability or warranty in case of usage for other purpose than the intended
one, ignoring this manual, operating by unqualified staff as well as unauthorized modifications to the de-
vice.

2.3 Reasonably foreseeable misuse
This device must not be used at potentially explosive areas!
The device must not be used at a patient for diagnosis or any other medical purpose!
Do not use these products as safety or emergency stop devices or in any other applica-
tion where failure of the product could result in personal injury or material damage.
Any failure to comply with these instructions could result in death, serious injury and material
damage.
2.4 Safety guidelines
This device has been designed and tested in accordance with the safety regulations for electronic devic-
es. However, its trouble-free operation and reliability cannot be guaranteed unless the standard safety
measures and special safety advises given in this manual will be adhered to when using the device.
1. Trouble-free operation and reliability of the device can only be guaranteed if the device is not subjected
to any other climatic conditions than those stated under "Specification".
If the device is transported from a cold to a warm environment condensation may cause in a failure of
the function. In such a case make sure the device temperature has adjusted to the ambient tempera-
ture before trying a new start-up.
2. If there is a risk whatsoever involved in running it, the device has to be switched off imme-
diately and to be marked accordingly to avoid re-starting.
Operator safety may be a risk if:
- there is visible damage to the device
- the device is not working as specified
- the device has been stored under unsuitable conditions for a longer time.
In case of doubt, please return device to manufacturer for repair or maintenance.
3 Product Description
3.1 Scope of supply
The scope of supply includes:
Pump GS 150, incl. 9V battery block
Operation manual
3.2 Operation and maintenance advice
Battery operation:
The device has 2 LED´s for status indication of the battery.
- if both LED´s are lighting, the battery is full
- if only one LED is lighting, the battery is low and should be changed soon.
- if no LED is on, the battery must be replaced
Note: by very weak batteries, a condition can occur that the LEDs will shine slighly.
The battery has to be taken out, when storing device above 50 °C.
We recommend taking out battery if device is not used for a longer period of time.
Treat device and sensor carefully. Use only in accordance with above specification. (do not throw, hit
against etc.). Protect plug and socket from soiling.
The pump is designed for dust-free gases. Already a small dust particle can lead to a re-
duction in pumping performance or to a function loss.
We recommend therefore always the use of a filter (e.g., GDZ 29) at the IN port.

Connect the tube to the measuring object to be sucked to pressure port "IN"
5 Reshipment and Disposal
5.1 Reshipment
All devices returned to the manufacturer have to be free of any residual of measuring media
and other hazardous substances. Measuring residuals at housing or sensor may be a risk for
persons or environment.
Use an adequate transport package for reshipment, especially for fully functional devices.
Please make sure that the device is protected in the package by enough packing materials.
5.2 Disposal instructions
Batteries must not be disposed in the regular domestic waste but at the designated collecting
points.
The device must not be disposed in the unsorted municipal waste! Send the device directly to
us (sufficiently stamped), if it should be disposed. We will dispose the device appropriate and
environmentally sound.
