External Device Wiring Diagram
Wiring external devices must be performed by a licensed
certified electrician or a qualified pool professional in accordance with the
current National Electrical Code (NEC), NFPA 70 or the Canadian Electrical Code
(CEC), CSA C22.1. All applicable local installation codes and ordinances must
also be adhered to. Improper installation will create an electrical hazard which
could result in death or serious injury to pool users, installers or others due to
electrical shock, and may also cause damage to property.
BE SURE TO DISCONNECT ALL SUPPLY CONNECTIONS BEFORE
