About This System

OWNERS MANUAL

B

The Nimbus Sierra reverse osmosis base unit must be serviced on a regular basis to maintain
efficiency and to safeguard water quality. Each unit is equipped with a pre-filter, a
membrane filter, and a post-filter. These cartridges work together to remove potential
contaminants from your tap water and must be replaced at regular intervals. The chart
below gives a general replacement timetable. For more accurate membrane filter
replacement intervals, the system should be tested for TDS by an authorized Nimbus dealer.
Instructions for cartridge replacement can be found in Section 10 of the Installation Guide.

Any significant change in performance of the system should be investigated promptly to
avoid secondary damage or deterioration to other parts of the system.

Performance Sheet

System Performance Feed Water Requirements

Daily production rate 42.8 L/d Feed water(3) Potable water

(11.3 gpd) Feed pressure 275 kPa, (40psi) to 552kPa (80psi)
Efficiency Rating(1) 8.8% Feed temperature 1°C (33°F) to 38°C (100°F)
Recovery Rating (2) 18% Total dissolved solids 2,000 mg/L maximum

Chlorine 1.0 mg/L max.

(1)Efficiency rating means the percentage of the influent water to the system that is available to the user as reverse
osmosis treated water under operating conditions that approximate typical daily usage.
(2)Recovery rating means the percentage of the influent water to the membrane portion of the system that is
available to the user as reverse osmosis treated water when the system is operated without a storage tank or when
the storage tank is bypassed.
(3)Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before
or after the system. Systems certified for cyst reduction may be used on disinfected water that may contain filter­able cysts. The feed water must also be free of potential membrane foulants such as Iron, Hydrogen Sulfide and
maganese.

System Tested and Certified by NSF International against NSF/ANSI Standard 58 for the
reduction of the contaminants listed below. The concentration of the indicated substances in
water entering the system was reduced to a concentration less than or equal to the permis­sible limit for water leaving the system, as specified in NSF/ANSI 58.

OWNER'S MANUAL

This system has been tested for the treatment of water containing pentavalent arsenic (also
known as As(V), As(+5), or arsenate) at concentrations of 0.30 mg/L or less. This system
reduces pentavalent arsenic, but may not remove other forms of arsenic. This system is to be
used on water supplies containing a detectable free chlorine residual at the system inlet or on
water supplies that have been demonstrated to contain only pentavalent arsenic. Treatment
with chloramine (combined chlorine) is not sufficient to ensure complete conversion of trivalent
arsenic to pentavalent arsenic.Please see the Arsenic Facts section of the Performance Data
sheet for further information.

Testing was performed under standard laboratory conditions, actual performance may vary.

Arsenic Facts

Arsenic (abbreviated AS) is a naturally occurring contaminate found in many
ground waters. Arsenic is water that has no color, taste or oder. It must be
measured by a lab test. Public water utilities must have their water tested
for arsenic. You can get the results from your own water utility. If you have
your own well, you can have the water tested. The local health department
or the state environmental health agency can provide a list of certified labs.
The cost is typically $15 to $30. Information about arsenic in water can be
found on the internet at the US Environmental Protection Agency website:
www.epa.gov/safewater/arsenic.html.

There are two forms of arsenic: pentavalent arsenic (also called As(V),
As(+5), and arsenate) and trivalent arsenic (also called As(III), As(+3), and
arsenite). In well water, arsenic may be pentavalent, trivalent, or a combina­tion of both. Special sampling procedures are needed for a lab to determine
what type and how much of each type of arsenic is in the water. Check with
the labs in your area to see if they can provide this type of service.

Reverse Osmosis (RO) water treatment systems do not remove trivalent ar­senic from water very well. RO systems are very effective at removing pen­tavalent arsenic. A free chlorine residual will rapidly convert trivalent arsenic
to pentavalent arsenic. Other water treatment chemicals such as ozone and
potassium permanganate will also change trivalent arsenic to pentavalent
arsenic. A combined chlorine residual (also called chloramine) may not con­vert all the trivalent arsenic. If you get your water from a public water utility,
contact the utility to find out if free chlorine or combined chlorine is used in
the water system.

The Nimbus Sierra system is designed to remove pentavalent arsenic. It will
not convert trivalent arsenic to pentavalent arsenic. The system was tested
in a lab. Under those conditions, the system reduced 0.30 mg/L (ppm) pen­tavalent arsenic to 0.010 mg/L (ppm) (the USEPA standard for drinking water)
or less. The performance of the system may be different at your installation.
Have the treated water tested for arsenic to check if the system is working
properly.

The RO component of the Nimbus Sierra system must be replaced yearly to
ensure the system will continue to remove pentavalent arsenic. The compo­nent identification and location where you can purchase this component are
listed in this installation manual.
