Operator Maintenance
NOTE THAT THIS EQUIPMENT SHOULD ONLY BE DISMANTLED BY
PROPERLY TRAINED PERSONNEL. REMOVING THE SIDE, FRONT
OR REAR PANELS EXPOSES POTENTIALLY LETHAL MAINS
VOLTAGES. THERE ARE NO OPERATOR MAINTAINABLE PARTS
WITHIN THE EQUIPMENT.
In the unlikely event that you experience any problems with your Dri-Block
®
which cannot easily be remedied, you should contact your supplier and return
the unit if necessary. Please include any details of the fault observed and
remember to return the unit in its original packing. Techne accept no
responsibilty for damage to units which are not properly packed for shipping:
if in doubt, contact your supplier.
1. Cleaning
Before cleaning your unit ALWAYS disconnect from the power suppply and
allow to cool below 50° C.
Your Dri-Block
®
can be cleaned by wiping with a damp soapy cloth. Care
should be exercised to prevent water from running inside the unit. Do not use
abrasive cleaners.
Before using any cleaning or decontamination method except those recommended
here, the responsible body or operator should check with Techne that the
proposed method will not damage the equipment.
2. Overtemperature cut-out
The overtemperature cut-out is a sensitive mechanical device and mechanical
shock can cause it to trip.
• In the event of no heater power, check the mains plug and lead, then reset the
cut-out control (located at the rear of the unit).
• Repeated operation of the cut-out indicates a serious fault: you may need to
return the unit to your supplier for repair.
3. Fuses
Your unit is protected by two fuses. These should only be changed by suitably
qualified personnel. If the fuses blow persistently, a serious fault is indicated
and you may need to return the unit to your supplier for repair.
