PRECAUTIONS
TANK LINING - DAMAGE PREVENTION
The water heater lining has been electronically inspected for continuity prior to final assembly. It was
found to be free of defects. In order to protect the lining, do not apply heavy blows or weld to the
exterior pressure vessel. Damage to the interior lining will void the warranty and ASME HLW stamp.
TANK MAINTENANCE - REMOVAL OF SEDIMENT AND SCALE
To keep the water heater efficient and in good working condition, inspect and clean two weeks after
installation to remove any piping system debris that may have accumulated. Do not acidize this unit.
Monthly inspections should be performed to determine a time span for removing any sediment
within the unit. This should become the basis for a routine maintenance schedule. It is recommended
that high-pressure water be used to purge any accumulation of sediment through the drain valve
opening or the hand hole.
ANODE MAINTENANCE
The water heating industry knows that many water heaters are installed in areas where the water supply
can be abnormally corrosive due to low pH or an excessive amount of dissolved oxygen. Because of
our commitment to provide clear water in all areas, an anode has been provided to help counteract the
effects of these factors. Periodic inspection and, if necessary, replacement is required to assure the
anodes effectiveness.
WATER QUALITY - pH LEVEL
Materials used in the water heater to prevent corrosion have been selected for their compatibility with
most domestic water supplies. However, significantly alkaline water (pH 7.5 or higher) or acidic water
(pH 6.5 or lower) can result in abnormal scale formation or seriously attack these materials and cause
premature corrosion. If the pH of incoming supply water does not fall between 6.5 and 7.5, it must be
treated to prevent damage to internal water heater surfaces and other building plumbing components.
