Assembly

Stand:
The stand should be pre-mounted according to directions in the
operating instructions. It should be positioned so that the arrow
mark (on the base cross) is pointing forward at the lab table. The
heat bath should be placed on the right next to the foot standing
in front.
Drive:
First, insert the extension into the bore hole on the back of the
device and screw it securely in place with the cylinder head scr-
ews enclosed.
Using an R 271 cross sleeve, fasten the drive onto the stand. To
do this, clamp the cross sleeve in place on the stand tube about
20 cm above the operating knob of the stand.
It should be easy to tip driver counter clockwise, move it into the
cross sleeve with the extension and clamp it in place. The drive
must be aligned so that it is sitting vertically above the operating
knob of the stand.
Placing the vapour tube in the drive:
Turn the ring (R) to the left unit it
will go no further. Push the
vapour tube in and then turn the
ring (R) to the right until it will go
no further.
The disassembly follows the
direction in the opposite order.
Glass sets:
Drawings with lists are included with the different glass sets. The
glass sets should be mounted on the drive according to these dra-
wings.

Commissioning

Check whether the voltage specified on the type plate matches
the mains voltage available. The power socket used must be
earthed (protective earth conductor contact). If these conditions
are met, the device is ready to operate after plugging in the
mains plug. If these procedures are not followed, safe operation
cannot be guaranteed and/or the equipment may be damaged.
Observe the ambient conditions (temperature, humidity, etc.)
listed under "Technical Data".
When working with the evaporator, it has proven useful to fol-
low certain orders while placing the unit in service. These orders
are designed to largely prevent foaming, which is highly undesi-
rable, or to at least keep it under control. If the evaporation pro-
cess is running satisfactorily, a vacuum controller can cover sub-
sequent monitoring.
The IKAVAC VC2 vacuum controller allows for recover rates of
up to 99%. Working principle: Vacuum control by assigning a
defined pressure value.
Recommended start-up sequence
• Set the equipment to the target pressure using the vacuum
control before filling the vacuum flask to minimise solvent los-
ses.
(It is of course also possible to fill the vacuum flask before app-
lying the vacuum.)
• The distilland is now sucked into the evaporating flask via the
feed pipe and the flask is immersed in the heating bath. This
is a more environmentally friendly way of filling the flask.
•Switch on the rotary drive and gradually increase the speed.
This prevents temperature stress on the glass when you start
the heating process and set the required temperature at the
heating bath.
