C H A P T E R 2 Introduction This chapter covers health and safety guidelines that should ensure the safe installation, operation and maintenance of the Accessory. You should read this chapter in conjunction with the Health and Safety manual for your system. Warning Failure to follow these guidelines, particularly when making a measurement, could result in the emission of laser radiation.
C H A P T E R 2 S m a l l V o l u m e S a m p l e D i s p e r s i o n U n i t Laser safety It should be noted that the Accessory does not contain a laser, but is connected to the Mastersizer optical unit that does.
C H A P T E R 2 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.

C H A P T E R 9 Introduction This chapter provides information on certain maintenance routines that can be carried out by the user. Read the “Access to the Accessory” section in chapter 1, for guidance on what the Supervisor and the Operator are allowed to do.
C H A P T E R 9 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  pipes.
‘O’ rings (Ç and È). The ‘O’ rings can be removed by levering them out using a pair of tweezers. Fitting the ‘O’ rings is the reverse of the above procedure. Replacement ‘O’ rings can be obtained from Malvern Instruments. Reassembly Reassembly is the reverse order to disassembly.
C H A P T E R 9 Once the electrical connectors and sample tubes have been attached, check the unit for leaks. Remember not to run the motor for more then a few seconds without liquid in the tank. Cleaning the cell windows Cleaning the system by rinsing through with fresh dispersant a couple of times is usually sufficient to prepare for a new measurement.
