The following section briefly discusses the various faults that can occur in the dryer, the reason of the
fault and how it can be rectified. If you do not find the solution to your problem, contact your Aircel
representative or the factory. All necessary safety and precautionary steps must be followed before
attempting to perform any of the recommended measures to resolve any faults in the air dryer.
Before any attempt is made to undertake any action, the machine must be shut down, isolated,
depressurized, and powered down. Follow the shut down procedures.

Some troubleshooting will have to be done while system is pressurized and
energized so use extreme caution.

2. Check to make sure if the unit has been damaged externally or if any part is missing.
3. Check if there is proper power supply and if it corresponds to that mentioned on the data plate.

5. Check if control air is available and the proper pressure at all pneumatically operated components.
6. Make sure all shut-off valves are in the correct position.
