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 or 20% Citric Acid Descale 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.
CAUTION!
