ADDITIONAL INFORMATION


Note that this equipment should only be dismantled by properly trained personnel. Removing the

outer cover exposes potentially lethal mains voltages. There are no user serviceable parts within this

equipment.

FAULT FINDING

Should you have any problems with your Dri-Block

®

heater which cannot be easily remedied, you

should contact your supplier and return the unit if necessary. Please include details of the fault

observed and remember to return the unit in its original packing. Bibby Scientific Ltd. accepts no

responsibility for damage to units which are not properly packed for shipping: if in doubt, contact your

supplier, giving the full serial number of the unit.

FUSES

If the display on the front panel is not lit, one of the two fuses may have blown. Check that there is no

external cause, such as a faulty plug or lead. Check both fuses and replace the faulty fuse with a

new one of the correct value (fuse values are given on the label next to the power inlet). Note that

fuses should only be replaced by a qualified electrician.

The holder for the two fuses is built into the mains input socket. First remove the power cable and

then gently prise the fuse drawer open with a flat-bladed screwdriver or similar tool. Each fuse can be

removed by using the screwdriver as a lever.

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.

SAFETY OVER-TEMPERATURE CUT-OUT

In the event of a fault occurring which could cause the heater to over-heat, a thermal fuse will cut in

and remove power from the heater. This will occur when the temperature reaches approximately

192°C in the DB100 models and 240°C in the DB200 models.
