WL15: HOT TANK DESCALING
The Hot Tank requires removal of mineral deposits (descaling) on a regular basis. Typically
descaling should take place every 6 to 12 months to preserve the long-term health of your unit.
Use non-toxic cleaner such as ScaleKleen, DEZCAL, 20% Citric Acid Solution, or Undiluted
Vinegar Solution to remove mineral deposits as directed by the manufacturer depending upon
filtration and local water conditions.
Descaling is an important process that removes calcium deposits, or scale, that can build up
inside a tank over time. Calcium and scale is non-toxic but left unattended will hinder your
WL250 Water Treatment System’s performance.
WARNING!

gloves and eye protection when using chemicals. Refer to Material Safety Data Sheet for
specific requirements of each chemical product. Take all necessary precautions to
prevent sanitizer from contacting eyes, clothing, and any other surfaces in could damage
