Description Rheem 2400W Electric Storage Element Element Replacement Elevated temperatures may be present during element removal process. Personal Protective Equipment should be worn to prevent the risk of scalding. When replacing an element on a heater with a cylinder barrel that does not have an earth tab, ensure the metal surround of the element flange is in direct contact with the cylinder barrel flange to ensure a good earth contact is made. Conduct an earth continuity test as required by AS/NZS 3000 6.3.3.2. When a fault or leak is traced to the element, the water heater should be drained to prevent damage to flooring or floor coverings by accidental flooding. 1. Drain the water heater. 2. When the water heater is drained, undo the four element screws, removing thermostat clamp first. 3. Withdraw the element. Care must be taken to ensure the loop of the element does not catch in the cylinder opening and open out inside the cylinder. NOTE: Do not cut off the element and leave a portion inside the cylinder 4. Clean around cylinder fitting, fit gasket to new element and slide the element into the cylinder (reverse to step 3) taking care that it is in the correct orientation. See element flange for orientation directions. 5. Replace screws and thermostat clamp and tighten. 6. The earthing of the internal storage cylinder relies on a good electrical contact between the metal surround of the element flange and the cylinder barrel flange. An earth continuity test should be performed whenever an element or element gasket is replaced, adjusted or serviced in any way. This continuity test is performed between the heaters internal storage cylinder and the main earth terminal of the water heater with a resulting reading of not more than 0.5 ohms as required by AS/NZS 3000 6.3.3.2. 7. Restore cold water supply and fill the storage tank. Release air by gently lifting the easing lever on the T&PR valve until water runs from the drain or opening hot taps. 8. Check for water leaks around the element flange. 9. Conduct an electrical insulation test. 10. Replace access cover and restore the power supply to the water heater.
