will begin heating or cooling to the set temperature. The Heating/Cooling indicator LED
will indicate the Heating or Cooling Function. A blinking indicator LED shows that the
system is nearing the temperature set point and will stabilize to the set temperature.
4.4 Operating the TropiCooler
The performance of the TropiCooler is dependent on the number of blocks in the well
and the ambient temperature in the laboratory. The TropiCooler will heat to its
maximum temperature in about 35 minutes and cool to its lowest temperature in about 2
hours. The use of the supplied Well Lid is recommended to ensure maximum
performance and efficiency of the system. The TropiCooler is capable of continuous
operation. However, it is recommended that the unit be turned off and defrosted if
substantial frost build up occurs on the block or in the well. This will allow the
TropiCooler to operate at maximum efficiency. Do not place wet or moist blocks into the
well. This may cause the block to freeze to the well thus making removal difficult.
