Replacing the fuse

Warning
If the Dispersion unit motor fails to run, check the fuse in the Dispersion
Controller. The fuse is located on the back panel of the Dispersion Controller,
refer to the illustration below
À
. Disconnect the mains power supply before
turning the fuse holder anti-clockwise so that the fuse tray may be pulled out. Lift
out the fuse.
If the fuse requires replacing, simply replace the fuse with a new fuse as specified
below:
The fuse required is:
20 mm 0.25A T
Cleaning the Accessory
It is recommended that periodically you disassemble the tank, pump and drain
assembly for maintenance and cleaning. The illustration below shows the
Dispersion Unit in its disassembled state. The main body of the Dispersion Unit
must only be dismantled after draining any dispersant in the system and
disconnection from any mains power supply.
Fuses must not be replaced by the operator. Only the supervisor or a Malvern
representative should attempt to replace the fuse.
