A. Removing the Cover
• Pry o the round knob with a small  at head screwdriver.
• Slide away the bottom cover by hand. (Figure 3.)
• Remove the two (2) screws attaching the water heater front cover. Remove the front cover.
• When reassembling, work in the opposite way.
B. Draining the Heater
If the heater has been installed with a drain valve, turn the water heater inlet o . Open a faucet or outlet in the
system. Then open the drain valve to drain the heater.
C. Removing the Heating Element
• Shut o the power supply and drain the water heater.
• Remove the front cover following the instructions above. Disconnect the wires from the element. See Figure
13.
• Use a pipe wrench to remove the element containing cap from the water heating assembly.
• Carefully remove the heating element.
D. Descaling the Heating Element
Scale deposits can a ect the heating capability of the element. Heavy scale can even cause damage to the
element. The element can be descaled either chemically or manually.
• Soak the element in white vinegar or other food grade descaling solution approved for use in potable water
systems.
• Once descaled, rinse well with a fresh water / baking soda solution.
The element can also be descaled manually:
• After the element has dried, use a soft brush (non-metallic to prevent damaging the element sheath) on the
element.
• Brush the dried minerals o .
Reinstall the element after descaling. Ensure the element gasket is installed and that the element is rewired
correctly.
Ensure the tank has been re lled with water before restoring power to the water heater. Failures due to “dry-
 ring” ARE NOT covered by warranty.
