Water Chemistry - Raypak 5350 Series Installation & Operating Instructions Manual

For your health and the protection of your pool equipment, it is essential that your water be chemically
balanced. The following levels must be used as a guide for balanced water.
Recommended Level(s)
Water Temp. (Deg. F)
pH
Total Alkalinity (PPM)
Calcium Hardness (PPM)
Salt (PPM)
Free Chlorine (PPM)*
Total Dissolved Solids (PPM)
*Free Chlorine MUST NOT EXCEED 5 PPM!
** In salt water chlorinated pools, the total TDS can be as high as 6000ppm.
• Occasional chemical shock dosing of the pool or spa water should not damage the heater providing
the water is balanced.
• Automatic chemical dosing devices and salt chlorinators are usually more efficient in heated water.
Unless controlled, they can lead to excessive chlorine level which can damage your heater.
• Further advice should be obtained from your pool or spa builder, accredited pool shop, or chemical
supplier for the correct levels for your water.
