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. A check
valve should be installed between the heater outlet and a chlorinator or other chemical dosing device.
Further advice should be obtained from your pool or spa builder, accredited pool
shop, or chemical supplier for the correct levels for your water.
