1. Insufficient inlet pressure
2. Electrical Fault
3. Moist or contaminated
desiccant
4. Too high air consumption
5. Excessive inlet air temperature
6. Insufficient purge air.
7. Exhaust silencer blocked
1. Inlet pressure min 58 psig (4 barg). If not adjust inlet
presure settings.
2. Ensure the power is on and the dryer front panel is
illuminated; check the dryer is cycling correctly.
3. Eliminate the cause of contamination. Replace desiccant
– do not re-use.
4. Ensure the performance of the dryer matches the
required system air consumption.
5. Check against technical specification.
6. Purge incorrectly adjusted. Consult service personnel to
adjust settings (Factory pre-set).
7. Consult service personnel.
8. Controller not functioning
correctly
9. Controller not illuminated
10. Insufficient inlet pressure
11. Failure to de-pressurize when
cycling.
12. Outlet flow stops
8. Ensure the controller is powered; check the on screen
column status to ensure it is powering the solenoid
valves during normal cyclic operation.
9. Inlet pressure min 58 psig (4 barg). If not adjust inlet
presure settings.
10. Check power to unit & fuse.
11. Solenoid valve not functioning correctly; if there is power
to the coil, replace valve. A correctly working valve
outputs an audible click when it energizes.
12. Check inlet air supply.
13. Failure to initialize dryer
14. Erratic air flow from exhaust
13. Switch off and restart dryer. Ensure dryer is pressurized
before powering dryer to allow dryer to initialize before
commencing operation.
14. Faulty or damaged valve; service required.
Poor dew point
performance
Problem Caused Problem Solution
Failure of dryer to
cycle
Constant
depressurization
15. Troubleshooting
Reference to known issue
Opening the inlet valve too quickly
Valve should be opened slowly allowing the pressure to build up gradually.
Inlet/outlet head pipe
Diameter too small.
Pipe work unsupported.
Inlet pipe work from low point in system, allowing bulk water to collect and enter the dryer.
Electrical controller
Incorrect fuse fitted or fuse blown. Check the plug and fuse located on top of the controller
back plate inside the dryer front cover.
Additional Items
Use of non-authorized components.
Untrained / unauthorized maintenance / installation personnel used.
Increase in air consumption without relation to the flow capacity of the dryer.
Purging the dryer with cleaning agents that could damage the components or the desiccant.
Covers removed or loose during operation.
Failure to carry out a service when indicated by the dryer.
Do not allow the dryer to flow air unless powered up, switched on and cycling. Resulting
effect could be desiccant contamination; requiring replacement desiccant.
