Congratulations on the purchase of your new ROM II or ROM III
Reverse Osmosis Modular Drinking Water System. You and your
family are about to enjoy better tasting, healthier water than
you ever thought possible. The ROM II uses superior design and
contaminant reduction performance of the prefilter cartridge with
a quick-change reverse osmosis cartridge. The ROM III blends the
proven superior design and contaminant reduction performance
of Everpure’s ROM II Processor with a third cartridge for superior
performance in reducing volatile organic chemicals.
The result is the best available combination of technologies to
reduce aesthetic contaminants such as dirt, minerals, tastes and
odors; and health related contaminants such as sodium, heavy
metals and organics (VOC’s).

NOTE: Read and save this manual.
The pages that follow will help you install your system. The
ROM II or ROM III System supplied by Everpure contains a
processor, storage tank, air-gap faucet, and drain connector.
This instruction manual details the installation for a typical
residential reverse osmosis application, but the ROM II or ROM
III System may be used with alternate equipment, such as a water
cooler. Manuals supplied with other components should also be
consulted during the installation. Read all manuals first to get a
clear picture of your project before you begin.
Outlined on page 7 of this manual are several maintenance
procedures you will need to do to guarantee optimum
performance of your system. Page 9 contains a troubleshooting
guide to assist in diagnosing operational problems if they arise.

1. PROCESSING SYSTEM
CAUTION:
CAUTION:
CAUTION:
This water processing system is acceptable for treatment of influent
concentration of no more than 27 mg/L nitrate and 3 mg/L nitrite
in combination measured as N and is certified for Nitrate/Nitrite
Reduction only for water supplies with a pressure of 280kPa (40 psig)
or greater.
The Everpure ROM II and ROM III Processors and their installations
are required to comply with state and local laws and regulations.
This reverse osmosis processor contains a replaceable treatment
component critical for the effective reduction of Nitrate. The product
water should be tested periodically to verify that the processor is
performing satisfactorily. Use the 8-way test strip (PN: EV6500-57) to
determine effluent Nitrate concentrations.
S-101 PREFILTER CARTRIDGE “A”
Cartridge “A” is the first cartridge in the ROM II or ROM III Processor.
It serves two purposes. Most importantly, it adsorbs the chlorine that
is found in most municipal water, keeping that chlorine from damaging
the TFC RO Cartridge “B”.
CONTACT WITH CHLORINE WILL DAMAGE
CARTRIDGE “B”.
Cartridge “A” also does an excellent job of reducing dirt which would
otherwise foul Cartridge “B”.
CHANGING CARTRIDGE “A” REGULARLY IS VERY IMPORTANT.
TFC RO CARTRIDGE “B”
Cartridge “B” is the second cartridge in the ROM II or
ROM III Processor. Cartridge “B” contains the reverse osmosis semipermeable membrane. This membrane is what sets this processor
apart from conventional filter systems. Here is where most of the
dissolved impurities are separated from the water molecules and
flushed down the drain. This cartridge should be replaced periodically
depending on the quality of the product water.
This reverse osmosis system contains a replaceable treatment
component critical for the effective reduction of Total Dissolved Solids
(TDS). The product water should be tested periodically to verify that
the processor is performing satisfactorily. Follow the TDS Performance
Testing procedure found on page 7 of the Maintenance section of this
manual to determine the reduction of TDS.
Replacement of reverse osmosis component should be with one of
identical specifications as defined by the manufacturer, to assure the
same efficiency and contaminant reduction performance.
This processor is not recommended for use with
an ice maker that discharges water to drain as part of the ice
production process.
3. AIR-GAP FAUCET (Supplied)
An air-gap faucet allows the product water to be drawn from the
storage tank when needed. It is NSF Certified for drinking water
use. The air-gap faucet contains a built-in air-gap to prevent cross
contamination. Any additional faucets connected to the system do
not require an air-gap, but must meet state and local health codes.
INSTALLATION PROCEDURE OUTLINE
1. Verify that the water is microbiologically safe.
2. Determine the best location for components.
3. Install the inlet water fitting.
4. Install the drain connection.
5. Mount the ROM Processor.
6. Verify the storage tank air pressure.
7. Position the storage tank.
8. Mount the air-gap faucet.
9. Install the postfilter (Not supplied).
10. Connect the components.
11. Install the Everpure cartridges.
SUGGESTED TOOLS FOR INSTALLATION
Screwdriver
Drill
Center punch
Small adjustable wrench
Safety knife
Eye dropper
Tire pressure gauge (0-20 psi)
Fresh 5-1/4% household liquid chlorine bleach (such as Clorox®)
VOC #1 ORGANICS CARTRIDGE “C” (ROM III ONLY)
Cartridge “C” is an optional third stage of treatment. Its function is
to adsorb any volatile organic chemicals that may get through the
RO membrane. This Cartridge conforms to ANSI/NSF 53 for VOC
reduction. See Performance Date Sheet for individual contaminants
and reduction performance. Cartridge “C” contains granular activated
carbon and should be replaced when Cartridge “A” is replaced.
2. STORAGE TANK
The storage tank stores the water that has been produced by the
ROM II or ROM III Processor. Because the storage tank is precharged
with air pressure to the manufacturer’s specifications, it provides the
pressure needed to deliver the product water to the air-gap faucet.
The storage tank generally contains sufficient pressure to connect
the product water to your remote ice maker. Consult the ice maker
manufacturer for flow rate and pressure requirements for your
ice maker.
