2.1. Proper Use

The SC 920G vacuum pump system is designed for use in
chemical, pharmaceutical, and biological laboratories. The vacuum
pump system is exclusively intended for transferring gases and
vapors.
Make sure that the installation location is dry and the pump/system
is protected against rain, splash, hose and drip water.
Vacuum pump system is solely for use in indoor areas.
Owner's responsibility
Only install and operate the vacuum pump system under the
operating parameters and conditions described in chapter 4,
Technical data.
Protect vacuum pump system against humidity.
Before using a medium, check the compatibility of the materials of
the pump head, diaphragm, valves, sealings and tubing with the
medium.
Before using a medium, check whether the medium can be trans-
ferred danger-free in the specific application case.
Only transfer gases which remain stable under the pressures and
temperatures occurring in the pump.
The high performance condenser must be installed on the outlet
side of the pump; if it is installed on the inlet side there is a danger
of implosion.
Observe the correct usage of the gas- and cooling liquid-
connections on the high performance condenser. Inlet and outlet
connections for the gas are not interchangeable.
Laboratory equipment or additional components connected to a
vacuum pump system have to be suitable for use with the pneu-
matic capabilities of the vacuum pump system (see chapter 4,
page 8).

2.2. Improper Use

The vacuum pump system may not be operated in an explosive
atmosphere.
The vacuum pump system is not suitable for transferring dusts.
The vacuum pump system is not suitable for transferring liquids.
The vacuum pump system must not be used if the entry of air or
gas into the vacuum pump system during venting (vent valve)
could result in the creation of reactive, explosive or otherwise
hazardous mixtures (e.g. with the medium).
The vacuum pump system must not be used to create vacuum and
overpressure simultaneously.
An overpressure must not be applied to the suction side of the
vacuum pump system.
