Reassembly of Shell Instructions
1) Install fittings into the inlet and outlet of the Bottom for the Risers that can supply a hydrostatic
pressure source.
2) One fitting should have a valve for the release of internal air pressure.
3) The other fitting should be attached to a source to apply the maximum allowable working
pressure, (MAWP) to the internal Coil and Riser Bundle.
4) Apply MAWP to the Coil Bundle.
5) Close off both inlet and outlet valves to retain the internal pressure for 20 minutes.
6) If leaks are detected, remove the internal pressure.
7) Remove the leaking Coil and inspect for causes for leak.
8) If the leak is due to debris, clean the Coil and reinstall.
9) If there are damages to any surfaces, contact your AERCO Representative for instruction for
returning the failed Coil.
