7. Commissioning
Initial Commissioning .
Refer to the General Arrangement (GA) drawing for the Air Supply Isolator systems operating layout.
If, after commissioning, the system does not perform as expected, refer to the Fault Finding Section.
Follow these steps:
1. Disconnect the air supply pipe from the inlet to the Air Isolation unit system.
2. Flush the pipe through with instrument quality air to remove any debris. This must be carried out for at
least 10 seconds for every metre of supply pipe.
3. Check all connections between the system and the downstream motor purge unit.
4. Close and re-open the internal valves. See No. 3 and 6 in the GA drawing.
8. Maintenance of the System
The maintenance recommended for the system consists of the following, supplemented by any additional local
requirements imposed by the local Code of Practice.
Expo recommends that the commissioning tests be repeated at every six to 24 months, dependent on the
environment. In addition the following checks are also recommended at that time:

Check the condition of the air supply filter element. Clean or replace it as necessary.
At least every two years, the following additional checks are recommended:

Apparatus is suitable for the Hazardous Location

There are no unauthorized modifications

The source of air is uncontaminated

Approval labels are legible and undamaged

Adequate spares are carried
9. Fault Finding
If the system does not behave in the manner described above there is a fault. Some of the more likely faults
are dealt with below. If a cure cannot be affected by following the procedure shown below please call Expo (24
hour answering) or your supplier for further assistance.
Check components by substitution only after establishing that such action is necessary. If the system is less
than 12 months old, parts under warranty should be returned to Expo for investigation, with a full report of the
fault and the system Serial Number.
As with any pneumatic system the greatest enemies are water, oil and dirt in the air supply. For this reason the
air system must always incorporate a dust and water filter to provide air to instrument quality.
