4 General information

4.1 Use

DF32 is a fully programmable, displacement filler (dispenser) which as a single unit can dispense
liquids of volumes from 10 ml up to more than 2500 ml.

DF32 has been specially developed for laboratory and small scale industrial applications where gentle
handling of product, absolute accuracy and minimum use of time for preparation of production are key
parameters.

DF32 is programmable for a number of different applications, and full production documentation can
be printed, if a printer is connected.

This manual contains all information necessary for the daily operation of the unit and so the DF32
manual should be read before using the filler.

4.2 Unpacking and inspection

Please check that all ordered items have been received and that no items were damaged during
transport. In case of any defects or omissions, please contact Flexicon A/S or your local supplier
immediately.

When ordering spare parts or accessories for the DF32, please state the serial number, which is
stamped on the label on the bottom of DF32.

ALWAYS REMEMBER that this machine must be earthed.

4.3 The pump head

DF32 operates with a positive displacement pump, which has a very low impact on the product.
The pump head is made of materials which are compatible with pharmaceutical products.

The materials used are stainless steel AISI 316 and plastic PEEK.
The displacement pump of the DF32 is not suitable for products containing particles.

Fig. 4.1

Electrical connections:

The main cable supplied is connected to the integrated main socket (1) in the main isolator, which also

1

contains master fuses. The plug is connected to an earthed switch.

2 External GO plug for the connection of a foot switch or for an external starting signal.
3 RS-232 plug for printer connection.

Connections of pneumatics:

4 If DF32 is to run with pneumatic equipment, a supply of compressed and dry air should be connected to

the quick release clutch (4).
The female part of the quick release clutch is supplied with the machine, but is not fitted.

Filling nozzles with pneumatic cut-off valves:
5 Nozzles with internal cut-off valve shall be connected to connector 5.
6 Nozzles with external cut-off valve shall be connected to connector 6.
Pneumatically driven diving nozzles:
7 Hoses giving the downward movement should be connected to connector 7,
8 Hoses giving the upward movement should be connected to connector 8.
