Disassembly
To disassemble the Dispersion Unit, disconnect the Dispersion Unit from the
mains supply and unplug the motor connector À from the back of the Control
Unit. Remove the sample tubing from the sample out Á and sample return Â
pipes. Unscrew the four slotted screws located under the base of the Dispersion
Unit Ã.
On the underside of the main body identify the 3 smallest screws Ä, remove
these using a 3mm A/F hex key. Do not disturb the fourth (largest) screw. The
drain section Å can now be separated from the tank and motor section Æ.
The pump impeller É is now visible on the underside of the tank section.
Remove the impeller from the motor shaft by inserting a 1.5 mm A/F hex key in
one of the drive coupling screws (visible through the tank aperture) to stop the
shaft rotating and turning the impeller in a clockwise direction.
