3.6.1. Test run
We recommend you to conduct a test of the dampener before installing it in the system, to
detect if there is no air leakage through diaphragm shaft. In order to do so, supply
pressurized air through air inlet. Proper operation is, when there is no continuous air flow
through the muffler.
Note! Due to its principle of operation, when supplied with pressurized air, shaft may
perform one stroke, resulting in short air release through muffler, which is not considered
as a leakage.
After one week of operation retighten the nuts with appropriate torque.
