The COMSYS-8 produces chlorine, but an \u003cstrong\u003eexternal ORP\/pH controller\u003c\/strong\u003e reads water chemistry and modulates output so you stay in compliance with health-department free-chlorine and pH limits.

If a secondary cell or its power center drops offline, the remaining primary and secondary cells keep generating chlorine without interruption. The faulted cell reports the issue on its diagnostic display, so the service tech can rotate that cell on a scheduled visit instead of taking the pool down.\u003c\/p\u003e\n    \u003c\/div\u003e\n    \n    \u003cdiv class=\"comsys8-faq-card\"\u003e\n      \u003ch4\u003eCan a pool owner or operator install the COMSYS-8 themselves?\u003c\/h4\u003e\n      \u003cp\u003eNo. The COMSYS-8 is a commercial installation. The four power centers wire to a \u003cstrong\u003e220 VAC\u003c\/strong\u003e feed and the bonding and grounding must meet \u003cstrong\u003eNEC 680\u003c\/strong\u003e, which requires a licensed pool electrician.
