WATER QUALITY
It is the End User’s responsibility to have the
cooling water analyzed and chemically treated as
often as necessary so that it conforms to the
limits specified in Table 1. The water quality in
the chilled water, cooling water, and heat medium
circuits shall not exceed the following limits:
