RESTORE FACTORY DEFAULTS MENU
This control system menu allows the user to restore most of the control system’s user settings to their factory default settings.
User settings in the Alarm Output Setup and Display Settings menus are unaffected by executing Restore Factory Defaults
ACTION DISPLAY
From the Main Menu use the Up/Down buttons to select (highlight
in black) the “Restore Factory Defaults” menu.
Press the Operational Button underneath “SELECT.” The Restore
Factory Defaults menu will be displayed.
From the Restore Factory Defaults menu press the Operational
Button underneath “YES.” The display will show text confirming the
factory default settings have been restored.
Press the Operational Button underneath “BACK” to exit the Restore
Factory Defaults menu.
GENERAL
Periodically the drain valve should be opened and the water
allowed to run until it flows clean. This will help to prevent
sediment buildup in the tank bottom.
Periodically check the temperature and pressure relief valve
to ensure that it is in operating condition. Lift the lever at the
top of the valve several times until the valve seats properly
and operates freely.
Water heater maintenance includes periodic tank flushing and
cleaning, and removal of lime scale from the heating element.
The heater tank is equipped with an anode rod to aid in
corrosion control and should be inspected periodically (see
Anode Rod Inspection).
ANODE ROD INSPECTION
Each water heater contains at least one anode rod, which will
slowly deplete (due to electrolysis) prolonging the life of the
water heater by protecting the glass-lined tank from corrosion.
Adverse water quality, hotter water temperatures, high hot
water usage, hydronic heating devices, and water softening
methods can increase the rate of anode rod depletion. Once the
anode rod is depleted, the tank will start to corrode, eventually
developing a leak.
Certain water conditions will cause a reaction between the
anode rod and the water. The most common complaint
associated with the anode rod is a “rotten egg smell” produced
from the presence of hydrogen sulfide gas dissolved in the
water. IMPORTANT: Do not remove this rod permanently
as it will void any warranties. A special anode rod may be
available if water odor or discoloration occurs. NOTE: This
rod may reduce but not eliminate water odor problems. The
water supply system may require special filtration equipment
from a water conditioning company to successfully eliminate
all water odor problems.
Artificially softened water is exceedingly corrosive because the
process substitutes sodium ions for magnesium and calcium
ions.
The use of a water softener may decrease the life of the water
heater tank.
