The SmarterSpa-IL is the in-line version of the SmarterSpa. This model includes all of the components needed to install the SmarterSpa in-line with the Spa’s existing plumbing which will remove the electrode from view.
The Spa should have a continuously running small pump for consistent operation of the SmarterSpa. If the pump turns off, the SmarterSpa should also turn off so chlorine generation will stop when there is no flow.
WARNING: Making chlorine in the pipes when there is no water flow is dangerous and can lead to damage.
