Setting The Units For Temperature; Setting The Operating Temperature; After Use - Cole-Parmer HBC-100 Serie Manual De Instrucciones

Setting the units for temperature

The unit will normally be set to display in °C, if you require it to work and display in °F press both the UP
ARROW and DOWN ARROW buttons at the same time. To convert back, press both buttons again.

Setting the Operating Temperature

1. To display the set temperature on the digital display, press and hold the SET Temperature button.
To adjust the set temperature, press the SET Temperature button and hold it while pressing the UP
or DOWN buttons. When the SET Temperature button is released, the measured temperature is
displayed (in degrees Celsius).
2. Power is switched on to the block (and the indicator comes on) if the set temperature is higher or
lower than the block temperature.
3. When the measured temperature approaches the set temperature, the "power to the block"
indicator will begin to flash. As the measured temperature stabilises the indicator will stay on for
shorter periods.
4. There will be a time-lag between the block and the insert achieving the set temperature due to
thermal contact between them. The display may reach temperature in 2 or 3 minutes while the
insert may take 5 minutes or more to reach temperature.
Overtemperature cut-out
The unit is fitted with an overtemperature cut-out. It will operate if a fault develops and the unit exceeds
its maximum operating temperature. The cutout will remove power to the heaters or peltiers and return
the unit to ambient temperature.
If the cut-out trips, the unit needs to be turned off and then turned on again to reset it.
If the unit is switched off and then switched on again quickly this may cause the overtemperature cut-
out to trip. If this occurs, turn the unit off, wait 5 seconds or more then switch it on again.
Repeated tripping of the cut-out may indicate a fault and you should contact
your supplier for more information.

After Use

When you have finished heating samples, remember that parts of the unit inserts and
associated accessories may be very hot. Take the precautions listed earlier. We recommend
that the inserts should be allowed to cool to 70°C before being removed from the HBC
unit. They will still have to be handled with care
If you need to remove an insert while it is hot, fit the extractor tool into the locating holes
and lift the insert out carefully. Never leave the extractor tool in the insert while it is being
used in the HBC unit.
