IMPORTANT
Information specific to this system is printed in Italics.
Please read the entire manual before proceeding with the installation and startup:
Do not use where the water is microbiologically unsafe.
Always turn off the unit, shut off the feed water, and disconnect the electrical power when
working on the unit.
Never allow the pump to run dry.
Never start the pump with the reject valve closed.
Never allow the unit to freeze or operate with a feed water temperature above 100 °F.
NOTES
Changes in operating variables are beyond the control Alamo Water Refiners, Inc. 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 a RO system depends on proper operation and maintenance
of the system. This includes the initial plant startup and operational startups and shutdowns.
Preventing 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 is required in order to know
the actual plant 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 a RO system can be caused by changes in the feed water,
or can be a sign of more serious problems. The best insurance against problems leading to
membrane failures is to maintain a log on the operation of the RO system, water quality, and
temperature. For your reference, a typical log sheet is included in this manual.
