pressed, the water then flows through the cooling mod-

ule or directly to the water dispenser outlet. The entire

water system must be cleaned chemically at regular in-

tervals.

completion of chemical cleaning under observance of

the rules for microbiological water analysis and these

should be evaluated by an accredited laboratory.
