Interchangeable Blocks

Block removal

Ensure that the unit is turned

off and disconnected from

mains.

The block can be removed and

exchanged for another as

required.

Slide the quick release handles

in the direction shown above

and lift the assembly out of the

unit.

Never lift or carry the block by

one quick release handle,

always use both handles or

support the block underneath.

When refitting the block, or fitting a new one, slide the quick release handles in the opposite direction to

the above arrows to lock the block assembly into the unit.  The software will register the change and

calibrate the unit for the new block.

Remember to adjust the options in the Program Defaults Menu for the new application.

If you have fitted the flat block for slide applications you must choose Heated Lid OFF.  See the section

headed Program Defaults Menu.
