Operator Manual
GENERAL SYSTEM OPERATION
Before you start using this device,
operators must read and understand this manual in its
entirety. This manual of Operator's Instructions describes in considerable detail all of the steps
and procedures required to
safely
operate this device. With proper operation, maintenance, and
care, this device should give you years of reliable service.
It is
unsafe
to operate this device without a basic understanding of water treatment and a
thorough understanding of the contents of this manual. Inadequately treated water for
hemodialysis poses a severe threat to the health and safety of hemodialysis patients. Education
and training of the staff in these facilities is critical given the technically complex subject of water
treatment. Guidelines and other related information are available from:
- Food and Drug Administration (FDA)
- National Association of Nephrology Technicians/Technologists (NANT)
- Association for the Advancement of Medical Instrumentation (AAMI)
Incoming tap water contaminants, temperature, pH, pressure, and flow-rates have a direct impact
on the quality and quantity of the RO output. The operator must be aware of changing tap water
conditions. This can be easily accomplished with good, two-way communications with the local
municipal water supplier and with routine testing of the tap water.
This device was designed and built to filter RO/DI product water, and is not intended for any other
application.

5.
When steady stream of water flows from the sanitary sample port, signaling that the air has
been purged from the device, close the sanitary sample port.
6.
Let filters soak for 10 minutes at 45 psi (minimum).
7.
Slowly open the outlet valve fully to allow water to flow through the device.
8.
Filters are now on-line and ready for use.
