Check that the limit stop is functioning properly:
☞ Lower the lift by holding down the "M" key.
☞ The drive stops automatically when the preset desired lower end
position has been reached.
☞ Move the drive back to the upper position.
Filling the evaporator piston
Prior to filling the evaporator piston, a vacuum controller is used to re-
gulate the glass apparatus to the target pressure.
☞ Now fill the evaporator piston using the backfeed line, see fig. 20.
☞ Due to the vacuum present, the solvent is suctioned into the eva-
porator piston. This enables you to keep solvent loss due to suc-
tioning to a minimum.
☞ You can also fill the evaporator piston manually prior to creating
the vacuum. The evaporator piston should not be filled more than
half its volume.
Note: CAUTION! The maximum allowed load (evaporator piston
and contents) is 3 kg.
Maintenance and cleaning
The device is maintenance-free. It is subject only to the natural
wear and tear of components and their statistical failure rate.
The seal on the glass condenser should be checked at regular in-
tervals and replaced if necessary.
For cleaning disconnect the main plug.
To clean the device use only water with a detergent that contains
tensides, or use isopropylalcohol for stubborn soiling.

Setting up the heating bath
Refer also to the operating instructions for the RObath basic/di-
gital!
☞ Move the lift to the bottom position and check the position of the
heating bath in relation to the evaporator piston. When using lar-
ger evaporator pistons (2 or 3 litres) or depending on the angle of
the rotation drive, you can move the heating bath 50 mm to the
right.
☞ Fill the heating bath with the tempering medium until the evapo-
rator piston is surrounded by tempering medium to 2/3 of its vo-
lume.
☞ Switch on the rotation drive and slowly increase the speed.
Note: Avoid creating waves.
☞ Switch on the heating bath using the main on/off switch.
Note: Avoid stress on the glass due to different evaporator piston
and heating bath temperatures when lowering the evaporator pi-

ston into the heating bath!
Note: If non-original accessories are used that are not supplied by
ILMVAC, then it is possible that the 50 mm travel range provided
by the heating bath will not be sufficient. This applies in particular
when using 3 L evaporator flasks with foam brake.
Use the RV 10.3000 mounting plate to extend the heating bath tra-
vel range by 150 mm.
