Water Chemistry - Raypak raytherm p-1826 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 bal-
anced water.
Recommended Level(s)
Water Temp. (Deg. F)
pH
Total Alkalinity (PPM)
Calcium Hardness (PPM)
Salt (PPM)
Free Chlorine (PPM)*
Total Dissolved Solids
(PPM)
• 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, and which is not covered under warranty.
• Further advice should be obtained from your pool or spa builder, accredited pool
shop, or chemical supplier for the correct levels for your water.
