Troubleshooting
The following table should give an overview of possible errors and an instruction to check and to repair them (is not valid
for the starting-up period of cooler).
Error
Possible reason
Check/Repair
The presence of water
Overloading of the refrigeration
capacity of the cooler due to too
much water vapor or too great a
sample flow rate.
A fault in the condensate removal
equipment. The heat exchanger has
become full of condensate.
An air leak in the condensate
removal tubing.
The temperature of the air passing
through the heat sink is too high due
to the cooler being in an enclosed
box.
Failure of the sample cooler.
No sample gas flow
Heat exchanger plugged
Alarm shutoff
No power on cooler
Check for an obstruction
Remove heat exchanger from unit and
disassemble
Verify cool & dry indicators are Illuminated
Ensure cooler has power supplied
Condensate carry-over sensor
alarm/dry light not illuminated
Inadequate drain apparatus
Excessive flow rate
High ambient temperature
Defective cooler
Verify drain tubing is unobstructed and
equipment is functioning satisfactory
Reduce the flow rate
Reduce the ambient temperature (Increase
ventilation or relocate cooler)
Verify air flow across the heat sink
Hold hand in front of heat sink fins and
ensure air movement.
