4.
Check the reservoir capacity and quick connects. If it works with a small loop but not in the
system let’s look there. Is there gunk in the lines somewhere? Is the filter clogged? Are all the
lines properly connected? Is there a kink somewhere? Did it work for a while and then stop?
Repeat step 3.
Adjusting the Set Point Temperature
After the correct flow rate of >0.5 GPM to ~0.55 GPM has been verified, the Set Point will need
to be adjusted. To change the set point:
1.
Press or push button for more than 1.5 s to begin modifying the set point.
2.
Continue until the desired set point has been reached.
3.
The new set point will be loaded automatically after a 2 second delay.
4.
By pressing the clock symbol or SET it is possible to abort the modification.
Set the system set point to about 3 degrees or so less than the ambient temperature expected in the
laboratory environment. In a typical case the set point is set to 20 degrees C when the normal lab
ambient is 23 C. A more detailed explanation of the chiller front panel display is shown in
Figure.15.
