The A.O. SMITH 100109166 is a conversion kit designed to retrofit an electric water heater from a standard voltage configuration to a 208-volt, 4000-watt setup using six heating elements. The kit includes Apcom-sourced components and is intended for use in commercial or multi-family residential settings where 208-volt power is the available supply. Licensed plumbers and water heater service technicians perform this type of conversion to bring an existing tank installation into compliance with site-specific electrical service requirements. The six-element configuration is appropriate for larger storage-tank water heaters where uniform heat distribution across the tank is required.
This conversion kit is suited for electric storage-tank water heater installations operating on 208-volt service, commonly found in apartment buildings, hotels, and light commercial facilities. The Apcom designation indicates the element and control components meet established industry standards for water heater service. Technicians replacing or upgrading heating elements during routine maintenance or a voltage-configuration change will find this kit provides the necessary components in a single package.
Designed as an OEM-style replacement conversion kit for electric storage-tank water heaters requiring a 208-volt, 4000-watt, six-element configuration.
Installation should be performed by a licensed plumber or qualified water heater technician in accordance with local plumbing and electrical codes. Shut off the electrical supply at the breaker panel and close the cold-water inlet valve before beginning any element removal or replacement work. Drain the tank to the appropriate level before removing existing elements to prevent water damage and scalding hazards. Verify the existing wiring and thermostat settings are compatible with the 208-volt configuration before energizing the unit.
