Techne HB-1D - Manual (Page 27)

27
DO NOT TIP THE TUBE SO THAT THE COLOURED END IS DOWN AS THIS WILL CAUSE A
SPILLAGE.
3. The unit has been designed to conform to international safety specifications and is fitted with a re-
settable over-temperature cut-out. If, for any reason, the temperature rises above a safe level for
the instrument, the over temperature protection cuts out the heater, but the tubes continue to
rotate. Check the reason for the cut-out; if there is no obvious cause, reset the cut-out once the
unit has cooled. The reset, on the rear of the unit, is operated by pressing the centre of the button
indicated on page 19.
USER MAINTENANCE
O ring seals on the FHB16 hybridisation tubes
The O ring seals on the large 80mm diameter 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 Bibby Scientific Ltd. or your Techne 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 leak or break when the end caps are inserted. Further
tubes can be obtained from Bibby Scientific Ltd. or your Techne dealer.
Cleaning your HB-1D
Before cleaning your unit ALWAYS disconnect from the power supply and allow to cool.
You can clean the case of the HB-1D with a cloth dampened in soapy water. No part of the unit
should be immersed in solvents. Do not use acetone or abrasive cleaners.
DO NOT USE ETHANOL OR METHYLATED SPIRITS ON THE ACRYLIC DOOR; these may make
the acrylic go cloudy.
Before using any cleaning or decontamination method except those recommended in this manual,
the responsible body should check with Bibby Scientific Ltd. that the proposed method will not
damage the equipment.
If you spill the fluid
Because of the nature of operation of the HB-1D, the complete inside must be cleaned if a spillage
does occur. This is to remove any airborne particles which may have been blown around the system
and to guarantee full operator safety.
Switch the HB-1D off and disconnect it from the power supply. Follow this sequence of operations
when the HB-1D has been allowed to cool below at least 50°C:
•
Remove all glassware from the HB-1D.
•
Remove the plastic drip tray.
•
Clean all surfaces of the inner chamber using a suitable cleaning and decontaminating
solution. Be careful of the drive shafts.
Cleaning and decontamination materials recommended by Bibby Scientific include:
•
Lipsol®
•
Decon® 90
•
Neutracon®
•
Other mild detergent
