In the unlikely event that you experience any problems with your Thermoregulator 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
responsibility for damage to units which are not properly packed for shipping: if in doubt, contact your
supplier.
OpErATOr MAInTEnAncE
1. cleaning
Before cleaning your unit ALWAYS disconnect from the power supply and allow to cool below 50°C.
Your Thermoregulator 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.
2. Over-temperature cut-out
The over-temperature 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.
• 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.
TE-10A & TE-10D 230V 2 x F5A; 120/100V 2 x F10A
TU-20D 230V 2 x F10A; 120/100V 2 x T16A
These should only be changed by suitably qualified personnel.
The fuses must only be replaced by a fuse of the same type and value.
If the fuses blow persistently, a serious fault is indicated and you may need to return the unit to your
supplier for repair.
