The A.O. SMITH 100109187 is a three-element conversion kit designed to upgrade or replace the heating element assembly in compatible electric water heaters. Rated at 6000 watts and 480 volts, this kit provides the electrical components needed to convert or restore a water heater to three-element operation. The kit is manufactured under the Apcom line and is intended for installation by licensed plumbers or qualified water heater service technicians working on commercial or high-demand residential electric water heating systems.
This conversion kit is suited for electric water heater applications that operate on 480-volt power supplies, a configuration common in commercial and light industrial settings. The three-element design distributes heating load across multiple elements, which can improve recovery rates in high-demand hot water systems. A licensed technician familiar with high-voltage water heater service should handle installation.
Designed as an OEM-style conversion kit for compatible A.O. SMITH electric water heaters configured for 480-volt, three-element operation.
Installation should be performed by a licensed plumber or certified water heater technician. Always shut off power at the breaker panel and close the cold water supply valve before beginning service. High-voltage systems at 480 volts require strict adherence to NEC guidelines and local electrical codes. Drain the tank sufficiently before removing or replacing any heating elements to prevent damage or injury.
