Operator Maintenance

General
Should you experience any problems with your HB-1D which cannot be easily
remedied, you should contact your supplier and return the unit if necessary.
Fill in the Decontamination Certificate provided with the unit and return it to
Techne Service department giving as much information as possible to help diagnose
the fault. Please remember to return the unit in its original packing, Techne accept no
responsibility for damage to units which are not properly packed: if in doubt, contact
your supplier.
Overtemperature Cutout
The overtemperature cutout 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
cutout control by depressing the centre of the button.
Repeated operation of the cutout indicates a serious fault: you may need to
return your unit to your supplier for repair.
Fuses
If the power indicator fails to light when power is supplied to the unit the fuses
may have blown. Check that there is no external cause such as a faulty plug; check
both fuses and replace any faulty fuse with one of the correct value. Fuse values are
given on the label next to the mains input socket.
O ring seals on the Hybridisation Tubes
The O ring seals on the 80mm dia Hybridisation Tubes must be checked
regularly and replaced before a leak occurs. Each tube is provided with 6 spare O
rings and further O rings can be obtained from Techne or your dealer.
Hybridisation Tubes
The Hybridisation Tubes must be checked regularly and replaced if any
damage occurs. Any damage to the ends of the tubes can cause them to break when
the end caps are inserted. Further Tubes can be obtained from Techne or your
dealer.
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.
