Rebound Break
The Rebound Break is for 15-20 minutes. This
is highly recommended
as some residual
disinfectant could still be present in the membranes even if a negative result was obtained during
rinsing. After the rebound break time has been completed (15-20 min), restart the RO in normal
Operate mode again and recheck for Residual. If the residual is positive, continue to rinse until a
negative result is achieved. Once the residual is negative, turn off the RO and allow for another
Rebound Break of 15-20 minutes. Turn on the RO and re-check for residual. Repeat this
process as many times as necessary until a negative Residual is obtained after the rebound
break.
