4.1 Operator maintenance
NOTE THAT THIS EQUIPMENT SHOULD ONLY BE DISMANTLED BY
PROPERLY TRAINED PERSONNEL.
REMOVING THE CASE 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 unit which cannot easily be
remedied, you should contact your supplier and return the unit as necessary. Please include any
details of the fault observed and remember to return the unit in its original packing. Techne accept
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 and the firmware version number
(shown on the LCD screen when the unit is first switched on). See the De-contamination
Certificate supplied with your unit.
4.1.1 Cleaning PrimeQ
Before cleaning your unit ALWAYS disconnect from the power supply and allow to cool below
50°C.
The thermal block, including wells and flat surfaces, should be cleaned regularly to ensure
optimum heat transfer to the samples. Always clean the block if there has been a spillage. Use a
cloth or cotton buds dipped in a fresh, 50:50 water/isopropanol solution and make sure that no
deposits are left in the wells.
The unit can be cleaned by wiping with a damp soapy cloth. Care should be exercised to prevent
water from running inside the unit. A cloth dipped in ethanol, methanol or formaldehyde can also
be used. No part of the case or cover should be immersed in the solvents. Do not use aggressive
solvents such as acetone or abrasive cleaners.
In the case of radioactive spillages, Techne recommend that you use a proprietary cleaning agent.
Carefully follow the cleaning agent manufacturer’s instructions. The thermal block is made of
aluminium. Therefore, an agent such as Neutracon (from Decon Laboratories Ltd.), suitable for
nonferrous metals should be used but remember other parts of the unit are made of ferrous
materials and may be damaged by spillage onto them.
Before using any cleaning or decontamination method except those recommended here, the
responsible body should check with Techne that the proposed method will not damage the
equipment.
4.1.2 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.
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 power input socket. First remove the power cord, and
then gently lever 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.
