If debris is found in the piping system, then the SuperVent needs to be cleaned. Proceed as follows to clean the Concentrator:

  1. For Blow Down Version (Model T or F), open ¾” (19mm) ball valve at bottom of SuperVent.

For SV173 SuperVent replacement, do the following:

  1. Reduce system pressure.
  2. Remove SV173 SuperVents by unscrewing threaded connection on top of vent check. With vent check installed, pressure relieving or draining is not necessary.
