Concentrator plus / Vacufuge® plus — Operating manual
5.3 Preparation for concentration
5.3.1 Switching device on
Switch device on, using the mains switch.
• Display is active.
• Lid is released (lid indicator lamp lights up).
• You can now open the lid.
• The parameter settings of the last run are displayed.
5.3.2 Inserting rotor
Proceed as follows when inserting the rotor.
1. Place rotor on the motor shaft.
2. Push rotor down using slight pressure until you encounter resistance.
5.3.3 Warm-up phase
The diaphragm vacuum pump reaches the displayed output and the ultimate pressure (see
Technical data on page 37) only after the device has gone through a 15 minute warm up phase.
The warm up phase prevents the condensation of liquid in the pump and on the lid of the rotor
chamber and therefore prolongs the service life of the pump.
1. time arrow keys: Set time to 15 minutes.
2. brake: switch brake on or off.
3. temp: select temperature.
Hint!
Please note before putting the device into service that the ambient temperature during operation
must be between 15 and 35 °C.
At altitudes above 3,000 ft MSL (risk of insufficient cooling air supply), measures in accordance
with DIN EN 60034-1; VDE 0530-1 are required.
WARNING!
Warning! Risk of injury from corroded or damaged rotors and buckets.
Even minor scratches and cracks can result in serious internal material damage.
Protect all parts from mechanical damage.
When inserting the buckets in the swing-bucket rotor, ensure that they do not scratch it.
Check accessories regularly.
Do not use rotors or buckets showing signs of corrosion or mechanical damage (e.g.
deformations).
Hint!
First note the rotor information (see p. 12) and the special notes on rotors F-45-72-8, F -45-48-11,
F -45-24-12 and A-2-VC (see p. 13).
Rotor A-2-VC: remove the buckets before inserting the rotor and pick it up at the rotor cross,
using both hands.
Hint!
The rotors do not need to be screwed in.
WARNING!
Warning! Risk of injury from fingers being crushed.
When closing the device lid, do not reach between the lid and the device or into the latching
mechanism of the lid, as your fingers may be injured.
