INTRODUCTION

HOW DOES THE POWERED ANODE SYSTEM WORK?

The Powered Anode System replaces sacrificial anodes which are normally shipped with water heaters. In order to protect the water heater from corrosion, a traditional anode deteriorates over time. As a result, when an anode is consumed by the corrosive effects of water, the tank will begin to deteriorate. Leaks result. However, the Powered Anode System will not be consumed over time, and if it is not working properly, its alert system will notify you. In short, the Powered Anode System measures the low levels of voltage that exist in the tank’s water. It then supplies the necessary current (very slight) to help protect the tank’s metal parts. It may also control water odor.
NOTICE: The powered anode system must remain plugged into a non-switched, powered outlet. Failure to do so could result in water heater damage, leaks, and property damage.

ON WHICH MODELS CAN I USE THE POWERED ANODE SYSTEM?

The Powered Anode System can be used with any 3, 6, or 9 element commercial water heaters water heater between 50 gallons and 120 gallons.

Note: One of the anodes will need to be removed. If you are unsure of your anode’s location, refer to the manual or call the manufacturer’s technical assistance number

PROCEDURE

1. Shut off the electric power supply to your water heater.
   Refer to the shutdown instructions in your water heater’s manual.
2. Drain the water heater according to these steps:
   • A. Turn off the cold water supply to the water heater.
   • B. Open hot water faucets to relieve the water pressure.
   • C. Attach a water hose to the drain valve. Run the hose to a drain or outdoors.
   • D. Open the drain valve and drain about five gallons of water from the water heater. (Water inside the heater will help hold the unit steady while removing the anode rod.)
   • E. Close the water heater drain valve, then close the hot water faucets.
3. Remove one of the old anode rods.
   • A. Locate the anode rod’s hex head on top of the water heater.
   • B. Loosen the hex head with a quick burst from the impact wrench (1-1/16” socket).
