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.
WARNING!
PERSONAL PROTECTIVE EQUIPMENT REQUIRED.
Always ensure proper
ventilation and use rubber or nitrile gloves and eye protection when using chemicals.
Refer to Material Safety Data Sheet for specific requirements of each product.
