the amount of mineral buildup, a larger
quantity of solution may be required. Use
the ratio in the table below to mix enough
solution to thoroughly de‑scale all parts.

De‑scaler 1 gal (4 L)
Step 7 Use half of the de‑scaler & water
mixture to de‑scale all components. Use
caution not to expose electrical connectors
to liquid and soak parts for 5 minutes
(15 ‑ 20 minutes for heavily scaled parts).
The solution will foam when it contacts
lime scale and mineral deposits; once the
foaming stops, use a soft‑bristle nylon
brush, sponge or cloth (NOT a wire brush)
to carefully de‑scale the parts. When
de‑scaling is complete rinse all removed
components with clean water.
