Electrical safety warnings
The Accessory is mains powered and input power cables should be treated
accordingly.
The metal parts of the instrument are earthed via the protective earth connection.
Never run the equipment without a protective earth connection.
Exert care when measuring samples to avoid liquid or powder spillages over the
Controller Unit. Conducting materials or liquids can break down insulation and
cause dangerous conditions within the Accessory. Should such spillages occur,
disconnect the power and scrupulously clean up before re-applying power to the
Accessory.
'
N o t e
. The operator should under no circumstances remove the covers of the
Controller Unit. If it is suspected that liquid or powder has entered the
Controller Unit call your Malvern representative to arrange for a service
call.
Opening the covers of the Controller Unit will render its calibration
void.
Sample handling

Warning
Always handle all substances in accordance with the COSHH regulations (UK)
or any local regulations concerning sample handling safety.
Use the Accessory in a well ventilated room if noxious samples or dispersants are
to be analysed.
Highly flammable and volatile solvents such as Methanol, Ethanol, Acetone and
Benzene may be used in the Dispersion Unit with care. It should, however, be
noted that the Dispersion Unit contains a brushed DC motor which is not vapor
protected.
Always consult the Materials Safety Data Sheets of all samples that are to be
measured.
