| Notes: |
The dew point was stuck at about 34C - not dropping to the set point of 20C. I found a crack in the "from cooler" tubing. I replaced this piece of tubing but this didn't solve the problem. There was an air bubble in this piece of tubing and the machine was making an unusual bubbling sound. Refilling the reservoir with DI water immediately change the sound, got rid of the air bubble in the tubing and the dew point began to drop towards the set point. |
