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 or
ethanol. No part of the unit should be immersed in solvents. Do not use acetone or
abrasive cleaners.
Before using any cleaning or decontamination method except those
recommended in this manual, the responsible body should check with Techne 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 ductwork system
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:
a)
Remove all glassware from the HB-1D.
b)
Remove the drip tray.
c)
Clean all surfaces of the inner chamber using a suitable cleaning and
decontaminating solution.
Be careful of the drive shafts.
Cleaning and decontamination materials which Techne recommend include:
Lipsol from Bibby-Sterilin Ltd
Decon 90
Neutracon
or mild detergent.
If an Incorrect Message is Displayed
If a message is displayed which shows a strange temperature or HELP, the PRT
(temperature sensor) has probably gone open circuit. This could mean that a wire has
broken; a wire or the connector to the PCB has become disconnected; or the PRT has
been broken somehow; etc. You should contact your supplier and return the unit if
necessary. Remember to fill in the Decontamination Certificate provided with the unit
and return it to Techne Service department or your dealer giving as much information
as possible to help diagnose the problem.
