NOTES
Changes in operating variables are beyond the control of the system manufacture. The end user
is responsible for the safe operation of this equipment. The suitability of the product water for
any specific application is the responsibility of the end user.
Successful long-term performance of an RO system depends on proper operation and
maintenance of the system. This includes the initial system startup and operational startups and
shutdowns. Prevention of fouling or scaling of the membranes is not only a matter of system
design, but also a matter of proper operation. Record keeping and data normalization are
required in order to know the actual system performance and to enable corrective measures when
necessary. Complete and accurate records are also required in case of a system performance
warranty claim.
Changes in the operating parameters of an RO system can be caused by changes in the feed
water or can be a sign of trouble. Maintaining an operation and maintenance log is crucial in
diagnosing and preventing system problems. For your reference, a typical log sheet is included
in this manual.
