rating plate (located on the back of the unit). Ensure that the voltage selector switch (located above
the On/Off switch) is set to the appropriate voltage for the local supply. Please note that the unit must
be earthed to ensure proper electrical safety. Connect the mains cable to a suitable plug according to
the table below.

3. UK ONLY: The fused plug supplied with the mains cable is fitted with a 10 Amp fuse to protect the
instrument and the user.
4. Units showing 230V, 50/60Hz on the rating plate also operate between 198 and 252V; units set to
115V, 50/60Hz also operate between 110 and 130V and units marked with 100V will operate between
90 and 110V. In all cases the heating rate will degrade by approximately 8% at the extremes of the
voltage range.
5. Plug the mains cable into the socket on the back of the instrument.
6. Place the unit on a suitable flat bench or in a fume cupboard if required, ensuring that the air inlet
vents on the underside are free from obstruction. Position the instrument with a minimum distance all
round of 200mm from walls or other items and between each unit if multiple units are being used to
permit efficient air flow for each instrument.
7. Switch on the instrument:
I
mains switch On
O mains switch Off
Replacement cable
Should the mains lead need replacement, a cable of 1mm
2
of harmonized code H05VV-F connected to
an IEC320 plug should be used. IF IN DOUBT CONSULT A QUALIFIED ELECTRICIAN.
