2. Use
2.1. Proper use
The pumps are exclusively intended for transferring gases and va-
pors.
Owner’s responsibility
Only install and operate the pumps under the operating parameters
and conditions described in Chapter 4. Technical Data.
Make sure that the installation location is dry and the pump is pro-
tected against rain, splash, hose and drip water as well as other
pollutions.
The gas-tightness of the connections between the application
pipes and the pump (or the pump connection) must be checked
regularly; with leaky connections, there is a danger that hazardous
gases or vapors may escape from the pump system.
Before using a medium, check whether the medium can be trans-
ferred danger-free in the specific application case.
Before using a medium, check the compatibility of the materials of
the pump head, diaphragm and valves with the medium.
Only transfer gases which remain stable under the pressures and
temperatures occurring in the pump.
Laboratory equipment or additional components connected to a
vacuum pump system have to be suitable for use with the pneu-
matic capabilities of the pump. (see Chapter 4. Technical Data).
