8. Trouble Shooting
8.1. Cooling device does not switch on
1. Check whether the device has been correctly connected to the line power
supply.
2. The Pury alarm contact does not release the calorimeter for operation. The
ambient temperature is too high. Either reduce the ambient temperature or
program the Diff Ambient function to “off” .
8.2. Cooling block does not cool
1. The heat exchanger is fouled with dirt and must be cleaned.
2. The fan is delivering insufficient cooling air. Check fan.
3. Peltier cooling elements may be damaged.
8.3. Condensate carry-over to the gas outlet
1. The heat exchanger is filled with condensate. Condensate is not being
removed by the pump.
2. Check pump tubing.
3. Increase condensate pump duty cycle.
4. Gas supply flow rate is too high. Check if the sample gas flow rate exceeds
the 250 l/h maximum. Reduce flow volume.
