Millenium HX RO System
3030226 Rev. D 1-7 General Information
1.3 Applications
The Millenium HX Reverse Osmosis (RO) System is designed to purify water by forcing
water through a semi-permeable RO membrane. Water purified by reverse osmosis has
had approximately 95% of the dissolved inorganic contaminants and approximately 99%
of all microorganisms, pyrogens, particulates and organics with a molecular weight
greater than 300 removed. The quality of the purified water, referred to as product
water or permeate, depends on the quality of the RO feed water and normally is equal
to or exceeds standards set forth by AAMI and CSA for water treatment equipment
hemodialysis applications. Refer to Technote 103 for AAMI and CSA Product Water
Quality Standards.
1.4 Intended Use
The Mar Cor Purification Millenium HX Portable Reverse Osmosis Water Purification
System is intended to be used as dialysis accessory to produce water through reverse
osmosis for use with hemodialysis equipment.
The Millenium HX can be connected to hemodialysis equipment used in hospitals,
clinics and in home environments, in conjunction with the appropriate pre and post
treatment units, as a part of a water treatment system designed to meet current AAMI
and Federal (US.) Standards.
1.5Contraindications
WARNING:
This system is not designed, sold, or intended for use in producing water for
injection.
Mar Cor Purification systems are not intended to be used outside of the device
specifications and limitations, as outlined in this manual and other related material. If
this equipment is used in a manner not specified by the operating instructions, the
protection provided by the equipment may be impaired.
Millenium HX RO System
3030226 Rev. D 1-8 General Information
1.6 Environmental Considerations
Prior to the installation of the Millenium HX RO, it will be necessary to provide utilities
and create an environment suitable for the trouble free operation of the RO and its
accessories.
WARNING:
Ordinary pipe dope must be avoided since it may leach objectionable and
potentially dangerous impurities into the water.
CAUTION:
It is necessary to keep the RO from freezing to prevent serious damage to the RO.
CAUTION:
The use of mobile telephones or communication equipment in the vicinity of the
Millenium HX could adversely influence the performance of the machine. See
specification in Section 4.8.
CAUTION:
Millenium HX needs special precautions regarding EMC and needs to be installed
and put into service according to the EMC information provided in the Operators
and Service Manuals.
1.6.1 Power
The RO operates on 115/230 VAC single-phase power. Histories of power failure,
power surges, and low line voltages should be noted and reported to the manufacturer
or their agent as they may create adverse conditions for the operation of equipment.
1.6.2 Water
Reverse osmosis systems require a reliable water source (rapid pressure fluctuation of
greater than 10 PSI should be avoided to prevent damage). The RO needs a minimum of
20 PSI pressure at a minimum flow of 1.5 gallons per minute. It is important that water
is flowing at the design flow rate when testing water pressure rather than reading static
pressure. Inlet water must contain less than 0.1 ppm free chlorine.
1.6.3 Drain
A drain outlet is required for the RO. The drain must have a minimum capacity of 2
gallons per RO per minute of continuous flow for as long as and as often as the RO is
operating.
Millenium HX RO System
3030226 Rev. D 1-9 General Information
1.6.4 Water Purity
Plumbing materials can significantly contribute to the contamination of the water.
Metallic pipes (with the exception of 316 stainless steel) must be eliminated once the
purification process has begun. Schedule 40 or 80 PVC pipes, polypropylene, PVDF, and
other FDA recommended materials are suitable for most grades of purified water. Care
must also be exercised in the choice of a thread sealant.
1.6.5 Temperature
The RO is normally connected to a cold water supply. The performance specifications of
the RO are based on 77°F (25°C) RO feed water temperature. The Millenium HX
contains a VFD motor that will increase the pump speed when operating on cold water
helping to increasing the amount of product water produced.

Millenium HX RO System
3030226 Rev. D 2-3 Installation And
Initial System Start-Up
2.1 Installation Considerations
1. Select a location for the RO near the required utilities and dialysis equipment.
2. The RO requires 115 or 230 VAC for operation depending on model.
3. The RO requires nominally 1.5 GPM water at 20 PSI. Warmer RO feed water
(greater than 77°F (25°C)) will produce more permeate (product water), and will
consume more water. Inadequate RO feed water flow and pressure may cause
the RO to shut down due to low pressure. The water may also require some
pretreatment to ensure maximum performance and suitability. Mar Cor
Purification recommends that RO feed water be chlorine/chloramine free and
solids above 5 microns in size to be filtered out.
4. A free flowing drain with a minimum capacity of 2 GPM is required for the RO.
5. Back flow prevention may be required in accordance with local codes.
6. Special connections may be needed to connect to the facility water supply.
Connections vary with different facilities.
2.2 Installation Procedures
CAUTION:
If a carbon tank is present on the Millenium HX RO, the carbon tank must be
completely rinsed of all carbon fines and ash before connecting to the RO.
Otherwise, irreparable damage to the TF membrane and RO internals will result
(refer to Carbon Tank O&M Manual).
WARNING:
The Millenium HX RO is stored with Storage Solution from the factory. Follow all
Material Safety Data Sheet (MSDS) guidelines that are included with the RO.
CAUTION:
Supply water with a pH above 8.5 and containing chloramines will adversely affect
the operation of the RO membrane.
CAUTION:
Any pre-treatment device supplying water to the RO must be ready for use prior
to operating the RO.
