Exchange the faulty fuse in the fuse holder for a working fuse of the correct value. Finally, replace the

fuse drawer in the fuse compartment and push the drawer shut.

Fuses which blow repeatedly indicate a serious fault and you should return the unit to your supplier for

repair.

THE HEATED LID OVER-TEMPERATURE CUT-OUT

The heated lid is fitted with an independent circuit to protect it from overheating. In the unlikely event

of an over-temperature problem with the lid, the unit is fitted with a thermal fuse which will remove

power to the heater plate should the maximum temperature be exceeded.

INSULATION TESTING

This equipment is fitted with RFI suppression circuitry. Any check of the electrical insulation by means of

high voltage dielectric testing (for example as in BS EN 61010-1) must be carried out using only a DC

voltage.

This unit contains semiconductor components which may be damaged by electric field effects.

INTERCHANGEABLE BLOCKS

The block can be removed and replaced by another of the same sort or of a different sort. The software

will register the change and set up the unit for the new block.

Before removing the block, disconnect from the power supply and allow it to cool to below 50°C.

If you have fitted a flat block for slide applications, you must set the heated lid to OFF.

●

Slide the quick release handles in the

direction of the arrows indicated and lift the

block assembly out of the unit.

●

Never lift or carry the block by one quick

release handle, always use both handles or

support the block from underneath.

●

When re-fitting the block, or fitting a new

one, slide the quick release handles in the

opposite direction to lock the assembly into

the unit.

●

Open or closed padlock symbols are printed

on the quick release handles for easy

reference.

●

Remember to adjust the options in the

Options menu for the new block.
