Warranty
Factory warranty (shipped with unit) does not apply to units
installed or operated improperly.
In most cases, improper installation or system design causes
most operating problems.
1. Excessive water hardness causing a lime build up in the
copper tube is not the fault of the equipment and is not
covered under the appliance manufacturer's warranty (see
Water Treatment, page 28 and Water Chemistry, page 37).
2. Excessive pitting and erosion on the inside of the copper
tube may be caused by too much water velocity through
the tubes and is not covered by the appliance
manufacturer's warranty (see System Temperature Rise
Chart on page 26 for flow requirements).
