Concentrator plus/Vacufuge® plus — Operating manual
4.3.3 Complete system: connecting the gel dryer
Requirement
• 1 connecting hose (length: max. 50 cm, inner diameter: 5 to 7 mm, chemical resistant and
suitable for vacuum applications).
1. Screw the hose connection supplied (size: G1/4 ") into the thread of the stop valve on the
left-hand side of the device.
2. Connect the gel dryer to the hose connection, using the connecting hose.
4.3.4 Basic device: connecting the vacuum pump
You can connect the basic device to an external vacuum pump.
Requirement
• The vacuum pump is approved according to the standards of your country.
• A separator (e.g., emission condenser, cold trap or chemical trap) between the devices or
behind the vacuum pump, depending on the application.
• Pump maintains an ultimate pressure of at least 20 mbar. Its suction capacity is at least 1.8
m³/h.
WARNING!
Danger of explosion from gas mixtures.
When running several devices in parallel on a vacuum pump and/or in combination with a gel
dryer, an explosive gas mixture can develop in the vacuum system.
 Note the solvent properties and only carry out parallel operations with identical solvents or
solvents that evaporate in a non-hazardous manner.
Hint!
Vacuum pumps that meet these requirements, can, for example, be diaphragm or vane-type
rotary pumps. The specifications can be found in the technical data of the vacuum pump or
requested from the manufacturer. The manufacturer is also the contact for any further questions
regarding the correct handling of the vacuum pump, e.g. operation, use, performance,
maintenance, troubleshooting or the specifications and connection of a cold trap.
Hint!
Please contact Technical Service if problems occur when connecting a vacuum pump. You can
find the contact addresses at the end of the operating manual or on the Internet at
