3. Lime Build-up
CAUTION - Tank and tank compo-
nents should be delimed regularly
depending on local water condi-
tions. Excessive mineral build-up
on stainless steel surfaces can
initiate corrosive reactions result-
ing in serious leaks.
4. Water Pressure (CWT-APS,
CWTF-APS, CWT-TS, CWTF-TS,
CWT-TSR & CWTF-TSR)
