■Ni Chrome Heating Element—Aunique, patented flow
path ensures optimum heat transfer and extended
element life.
■Durable Design—Reduces calcification and sedimentation.
■Space Saving Installation—Compact size.
■High Temperature Limit Switch—Protects against element
burnout, with reset button.
■Warranty—Heaters aredesigned for durability and
guaranteed against failuredue to leaks of Heater
Body/Element Assembly for a period of 10 years. Field
serviceable element with replaceable cartridge element (1
year warranty).
