HOT TANK DESCALING INSTRUCTIONS
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 unit’s
performance.
