SECTION III: PREPARATION
A. Major System Components
The following components comprise the NRS-1
Drinking Water System:
1. A Nitrate Reduction assembly consisting of the
aluminum bracket, screws, wrench, filter
housing, installed nitrate filter, installed shut-off
ball valve with fittings.
2. An automatic shut-off water meter with installed
fitting on OUTLET.
3. A faucet kit with ¼” fitting.
4. A plastic tubing kit with feed water supply valve
and leak stop valve.
5.
Other items necessary for installation may
include wood screws or machine screws for
mounting the NRS-1 assembly, concrete
anchors may be required for hanging on
basement wall, additional tubing or tube
connectors, and plastic wire ties for organizing
tubing.
B. Tools Recommended for Installation
The following tools will cover most of the installation
sites encountered:
•
3/8" variable speed electric drill.
•
Extension work light with outlet.
•
Safety Glasses.
•
1-1/4" porcelain hole cutter kit.
•
1-1/4" Greenlee hole punch and 1/8" and
1/2"metal drill bits for pilot hole.
•
Center punch and hammer.
•
1-1/4" wood bit.
•
Assorted wood and metal drill bits including
7/32" metal drill bit.
•
Phillips head and flat blade screwdrivers.
•
1/2", 9/16" and 5/8" open end wrench.
•
10" Crescent wrench with jaws taped to
hold faucet.
•
Teflon tape.
•
Wide masking tape or duct tape.
•
Plastic tubing cutter.
•
Extra plastic tubing.
•
Small bottle of liquid chlorine bleach.
C. Determine System Location
The NRS-1 system can be located under a sink or
in a basement depending on space availability and
the custom
er’s preference. If a basement
installation is selected, additional tubing, hardware
and fittings may be needed and a hole will have to
be made from inside the cabinet, through the floor,
to the basement. Never install in an area of the
home where temperature is freezing as damage to
the system will result. If a reverse osmosis system
is to be installed in-line with the NRS-1, the NRS-1
should be the last device before the faucet.
Considerations for an ice maker or other remote
hook up should be determined, including routing
and any additional tools, fittings, and tubing that
may be required.
1) Faucet - The faucet should be placed near
the sink where drinking water is normally
obtained. Convenience of use (filling of
water pitchers and glasses), and an open
area beneath the faucet under the sink for
attaching product tubing are considerations.
A 2" diameter flat surface is required above
and below the mounting site. The thickness
of the mounting surface should not exceed
1-1/4".Watch for strengthening webbing on
the underside of cast iron sinks.
2) NRS-1 Assembly - The NRS-1 Assembly
may be mounted on either the right or left
side of the under-sink area or a cabinet.
Mounting in the basement is also an option.
The mounting location should allow
adequate clearance and accessibility for
cartridge changes.
3) Feed Water Connection - The feed water
valve should be located as close to the
NRS-1 assembly as possible.
4)
Leak Stop Valve
– Drinking water systems
inherently have many connections which
could leak. It is necessary to install the
included Leak Stop Valve very close to
and/or under the NRS-1 assembly. It must
be fastened to the floor or cabinet base with
screws or double-sided tape. The feed
water supply must pass through the Leak
Stop Valve (See page 9). Should a leak
occur and the underside of the Leak Stop
Valve gets wet, the feed water will be
terminated. Once activated, the Leak Stop
Valve can be reset one time (See page 12).
