5 Maintenance
5.1 Care and Cleaning
Routine Preventive Maintenance
DANGER
Risk of Scald- Before manually operating
the relief valve, make certain no one will be
exposed to the danger of coming in contact
with the hot water released by the valve.
The water may be hot enough to create a
scald hazard. The water should be released
into a suitable drain to prevent injury or
property damage.
NOTICE
If the temperature and pressure-relief valve
on the hot water heater discharges
periodically, this may be due to thermal
expansion in a closed water system.
Contact the water supplier or your
plumbing contractor on how to correct this.
Do not plug the relief valve outlet.
Properly maintained, your water heater will provide
years of dependable trouble-free service. It is
suggested that the following annual preventive
maintenance program be established.
1. Inspect Temperature Pressure Relief Valve.
2. Inspect heating elements, ECO, and wiring to
each.
3. Drain and Flush the water heater tank.
4. Anode rod must be removed and inspected.
Temperature and Pressure-Relief Valve
Once a year, it is recommended to lift and release
the lever handle on the temperature and pressure-
relief valve, located on the front-right side of the
water heater, to make certain the valve operates
freely. Allow several gallons to flush through the
discharge line to an open drain.
Heating Elements and ECO
Once a year, it is recommended to inspect the
heating elements, ECO, and wiring to each.
Inspection should be completed by service
personnel qualified in electrical appliance repair.
Most electrical appliances, even when new, make
some sound when in operation. If the hissing or
singing sound level increases excessively, the
electric heating element may require cleaning.
Contact a qualified installer or plumber for
inspection.
Heating Element Replacement Procedure
WARNING
If the heating element needs replacement, it
is very important to use the same voltage,
wattage, and construction. DO NOT replace
the heating element with a generic heating
element. Only heating elements are
approved for use with this water heater.
Failure to follow this warning will result in
premature product failure and VOID the
warranty, and could result in severe
personal injury or death.
STEP 1: Turn off power to the water heater. Use a
Phillips Head screwdriver to remove the wires from
the element.
DANGER
Failure to disconnect the power from the
water heater before attempting heating
element replacement will result in property
damage, severe personal injury, or death
due to electric shock.
STEP 2: Run hot water at a faucet in the system.
When it runs cold, shut off the faucet. Then shut off
water at the main cold water inlet or, if possible,
valve off the water heater from the system. Drain
the water from the system, or just the water heater
if it can be isolated from the system.
WARNING
Completely drain the water heater before
removing and replacing a heating element.
Failure to do so will result in a leakage of
water and property damage, and could
possibly result in moderate to severe
personal injury or death.
