Cleaning System using:

•Chlorine bleach (surface and municipal water)

This procedure is to be conducted after the internal prefilter has been removed from the System. Do not permit the Carbon Prefilter to come into contact with chlorine bleach or any other form of chlorine. During this procedure the water level in the System should be half way up the internal prefilter cavity. If necessary, add water by slightly opening the inlet ball valve while observing the water level.

Always wear safety glasses and protective clothing when handling cleaning chemicals.

Never intentionally or unintentionally mix chlorine bleach and MC-1 cleaner as poisonous and corrosive chlorine gas may be formed.
