Installation Instructions

Rusty water is usually an indication that the anode rod requires replacement. If rusty water is present, examine the
anode rod immediately and replace as needed. In the event of poor water quality, consult a local water treatment
professional for water treatment options. Always ensure the water heater is grounded. Damage resulting from
poor water quality or failure to replace the anode rod is not covered under the manufacturer’s warranty. For
additional questions, please contact Technical Support.
To change the anode rod:
1. Turn of the power supply and drain the heater (see Draining the Heater).
2. Remove the heating element (see previous section).
3. Unscrew the anode rod from threaded connection.
4. Remove and replace the anode rod (Figure 7, N).
5. Reinstall the heating element.
6. Re ll tank with water and purge air before restoring power.
E. 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 th stainless steel sheath)
on the element.
• Brush the dried minerals o .
Replace the anode rod if it is noticeably deteriorated or considerably smaller than described in Inspecting the
Anode Rod.
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.

Problem Solution
Water
Does Not
Get Hot
Ensure the power supply is on and working
If light does not come on, check that the high limit reset button is pushed in. Follow steps to reset
the switch, this manual.
If the indicator light works properly but temperature does not get hot at the tap, test for a plumbing
crossover. Shut o the cold supply to the heater and open the hot water tap. There should be no
water  owing. Any continued  ow indicates a crossover which will a ect the temperature and
need to be corrected.
Call a quali ed service technician to test the resistance of the heating element (8-10 ohms). Heating
element should be replaced if readings are outside these values.
Light Not
On
If the light does not come on, but the water gets hot, check for faulty bulb.
Check that the high limit reset button is pushed in. Follow steps, this manual.
Brown
Water
Brown or rusty water indicates a “spent” anode rod and possible deterioration of the tank body.
Check anode rod. See instructions, this manual. Inspect the tank for leaks.
Water
Odor
Smelly water could be due to an unusual reaction between local water and the heater’s anode rod.
Check anode rod. See instructions, this manual. Failure to do so may result in damage to the tank
and leaks.
Leaks
Check water  ttings and T&P  tting on top of tank. Remove front cover and inspect heating
element gasket.
If tank is leaking, review warranty to see if heater is still within warranty period.
