Introduzione Prima di utilizzare l’apparecchio, leggere tutte le informazioni contenute in questo manuale. Attenzione Le alte temperature sono pericolose: possono causare ustioni gravi all’utilizzatore e possono causare la combustione di materiale infiammabile.
Il fusibile all’interno dell’apparecchio protegge l’apparecchiatura e l’utilizzatore. Tenere presente che gli apparecchi riportanti sulla targhetta 230 V funzionano a 220V. Gli apparecchi riportanti 120V funzionano a 110V. Comunque, in entrambi i casi la velocità di riscaldamento diminuirà approssimativamente dell’8%. 3. Collegare il cavo elettrico alla presa di corrente sul retro dell’unità. 4.
Nell’eventualità che si riscontri un problema con l’apparecchio che non può essere facilmente risolto, si dovrà contattare il proprio fornitore e restituire, se necessario, l’apparecchio. Si prega di specificare nel dettaglio i difetti riscontrati e di ricordare di restituire l’apparecchio nel suo involucro originale. La Techne non si fa carico di alcuna responsabilità per danni subiti dall’apparecchio che non sia stato propriamente imballato per il trasporto; in caso di dubbio, rivolgersi al fornitore.
TE-10A, TE-10D and TU-20D Thermoregulator Before using the thermoregulator make sure you have read this manual carefully. Constant Temperature Baths Techne supply a range of liquid baths from 8 to 48 litre which can be fitted with any of the TE-10 or TU-20 thermoregulators. The B-8, B-12, B-18, and B-26 bath inner containers are manufactured from stainless steel for maximum corrosion resistance and are deep drawn with large easy clean corner radii.
Set Up 1 There are two modes of operation for the pump; circulation internal to the bath; circulation external to the bath. For internal circulation the blanking caps on the top of the outlet and return pipes should be securely in place. They screw on and, for safety, they may be tight. For external circulation these need to be removed. The outlet nozzle is supplied fitted to the bottom of the pump housing in the internal circulation position.
5 Begin by securing the bridge piece to the bath. Use the two M4 countersunk stainless screws and screw into the holes in the corners of the bath. Use M4 countersunk screws 6 Locate the thermoregulator above the bridge piece. Toggle the heating element carefully through the clearance hole. Lower the thermoregulator onto the M4 threaded stud (1) and 3mm diameter stud (2). Use the half-turn plastic fastener (3) to clamp down the thermoregulator.
8 If you do not want to use a bridge piece to secure the unit to a bath then you must use a clamp. The clamp bracket fits between the pump legs in the slot provided. Slide the bracket into the slot and use the two screws in the clamp kit to secure the clamp to the unit. Clamp Slot for clamp 9 If the pump has been set correctly for external circulation, suitable hoses should be fitted to the outlet and return pipes.
and moulding and use the screw to fit the cooling coil in the slots. Keep the moulding in a safe place in case you need to replace it. Connect a hose from a tap to one end of the coil and from the other end of the coil to drain. Adjust the water flow to give the required cooling. 11 For lower temperatures, a Dip Cooler such as a Techne RU-200 or RU-500 or a Flow Cooler such as the FC-200 or FC-500 is required.
15 A bath that is fitted with a lid or insulating ball blanket gives the best operating conditions. A lid or ball blanket will prevent vapour loss, heat loss and give better temperature control. If an open bath is used above 80°C (ie where steam or other readily condensing vapours are present) the operation of the unit, particularly the digital display on the TE-10D and the TU-20D, may be affected. Below about 80°C a cover becomes less important but will still give better temperature control.

OPERATION • Ensure that either the outlet and return pipes have their caps on or an external system is properly set up. Fuses Power switch Pipe connector or blanking cap Float switch (not the TE-10A) • Switch the unit on by pressing the power switch. The switch and the POWER indicator on the front will light up. Setting the temperature on the TE-10A • Turn the knob until the line on the knob points to the required temperature.
When SwitchING On the TE-10D or the TU-20D When first switched on the display will show the edition of the software currently installed. For example software issue “5.12” would be shown as follows: It will display this for 1 second, then the actual temperature of the bath will be indicated. The Front Panel Controls The front panel controls consist of three buttons for controlling the display, a four digit LED display and three indicators.
The DOWN ARROW button When the SET temperature button is held down and the DOWN ARROW button is pressed, the set temperature is decreased. Speed of change of set temperature Each press of the UP ARROW or DOWN ARROW buttons will increase or decrease the set temperature by 0.1°C. If the buttons are held down the temperature change will accelerate to 5°C per second. Power indicator The top indicator shows that there is power to the unit.
Over-temperature indicator If the unit should, for any reason, exceed the temperature set for the over-temperature cut-out, the over-temperature indicator will light. The heater will have been switched off and the unit will begin to cool even if the heater light is on (the light staying on or not depends on which circuit has sensed an over-temperature). Low liquid level The float switch will trip if the liquid gets below a safe level; the display will change to "LLL". The heater will be switched off.
After Use When you have finished heating samples, remember that parts of the unit and the samples may be very hot. Take the precautions listed earlier. We recommend that the samples should be allowed to cool to 50°C before being removed from the bath. They will still have to be handled with care. Should you want to remove the unit from the bath, it too should be allowed to cool to 50°C before being removed.
Setting the Over-temperature Cut-out An adjustable over-temperature cut-out is fitted. When the cut-out operates, the heater will stop working and the ‘over-temperature cut-out indicator’ will illuminate. On the TU-20D an audible alarm will sound. The pump will continue working on all units. Over-temperature reset button It should be set to approximately 10°C ABOVE THE OPERATING TEMPERATURE.
RS232 Serial Interface The TU-20D may send data logging information to a compatible computer by connecting the unit and the PC via an RS232 cable, and installing the “Thermsoft” software. Contact your supplier for details. RS232 Connection The RS232 cable must be fitted to both the unit and the PC before either unit is powered up, otherwise, data integrity cannot be guaranteed. Once the cable is fitted, it does not matter which unit is powered up first.
ADDITIONAL INFORMATION NOTE THAT THIS EQUIPMENT SHOULD ONLY BE DISMANTLED BY PROPERLY TRAINED PERSONNEL. REMOVING THE TOP CASE EXPOSES POTENTIALLY LETHAL MAINS VOLTAGE. THERE ARE NO OPERATOR MAINTAINABLE PARTS WITHIN THE EQUIPMENT. 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.
Calibration of the TE-10D and TU-20D Remember that if you change the calibration from that set at the factory you may change the calibration at all temperatures. You may get different calibration with different baths and/or liquids. In order to ensure that the calibration you are setting is correct, you will need to use an independent calibrated probe or thermometer. Set the temperature display to the particular temperature at which you require to control.
Replacement parts Each unit is supplied with an O ring for a thermometer.
Accessories There are many accessories both for the thermoregulators and the baths. These are constantly being updated and details can be found in Techne Sales literature.
