Equipment Safety - Pentair 320 Serie Manual De Instrucciones

Since most pool's plumbing is not airtight, and a mixture of air and chlorine is
highly corrosive to metals, it is important to protect these items from corrosion
in the OFF period when no circulation is taking place. (There is no chance for
chlorine corrosion when the circulating system is in operation.)
Of course, corrosion or erosion of metal components can still occur
independently of any chlorinator installation for the following reasons:
If your pool or spa has any of the following equipment, special plumbing
procedures must be followed for safe operation:
Installation of the OPTIONAL Rainbow #R172288 positive seal, corrosion
resistant check valve SHOWN ON REVERSE SIDE will prevent the backflow of
corrosive liquids and gases that can damage equipment containing metallic
components. Examples listed above.
WARNING: If your pool is equipped with a permanent built in
pool-cleaning system, damage could occur to that system if materials
are not compatible with low pH Tri-Chloro feeders. Check with
manufacturer for compatibility.
