D. Prepare the Area for Installation
Clear the area under the sink prior beginning the
installation.
If a basement installation is called for, determine
where components will be located and how they will
be mounted. Special mounting brackets and
hardware may be necessary to secure the system
to a wall or ceiling joists.
Inspect cold water supply line to determine if any
special fittings, in addition to what is included in the
kit, are required
E. Prepare the Appliance for Installation
Open shipping carton and remove components.
Check that all installation parts are present which
includes the NRS-1 assembly, water meter, faucet,
installation hardware, leak stop valve, tubing, and
wrench.
SECTION IV. INSTALLATION STEPS
All plumbing should be done in accordance with
state and local plumbing codes.
NOTE: Some codes may require installation by a
licensed plumber; check with the local plumbing
authority prior to installation.
In restricted under-sink areas, it may be easier to
install the faucet first. Allow adequate tubing
lengths for any final component position.
A. Install the Faucet
See Figure 1 for Faucet Installation Diagram
The faucet should be positioned so that it empties
into the sink and the spout swivels freely for
convenience.
If the sink already has a hole provided that can
accommodate the NRS-1 faucet, then no drilling is
required and you can proceed to the section on
mounting the faucet.
1. Make the Faucet Mounting Hole
IMPORTANT: It is mandatory that safety glasses
be worn during sink hole drilling operations to
prevent eye injury.
Before starting the hole making operation, always
check below the sink so that nothing interferes with
mounting the faucet such as reinforcing ribs,
support brackets or cabinet construction.
