C. Automatic Water Meter
Apply Teflon tape to threads on the INLET of the
water meter and screw the inlet of the meter into
the OUTLET of the filter housing. Meter should be
tightened enough so that there are no leaks and the
meter is facing the front of the NRS-1 housing
assembly. This will allow for ease of setting the
meter in gallons.
Tubing installation
1) Insert free end of feed water tubing into the
¼”
fitting on the water meter.
2) Insert the tubing into the fitting on the faucet.
D. Setting the Shut-off Meter
IMPORTANT: Before starting this procedure, make
sure a complete nitrate water test has been done
and those numbers provided.
The NRS-1 may be installed on water containing
nitrates, however the total nitrate concentration of
the incoming water supply should be less than 21.0
ppm. Water containing a nitrate concentration
greater than 20.0 ppm will greatly reduce the
cartridge capacity and leave potential of harmful
levels of nitrate bleed through. Treated level of
nitrate should be less than 10.0 ppm per the EPA.
Turn the setting dial of the water meter clockwise
so that the arrow point to 100, 150 or 200 gallons
for nitrate levels less than or equal to 20, 15 or 10
ppm (respectively). After the number of gallons is
exhausted the automatic shut-off meter will cut the
OUTLET flow of water and no more water will be
allowed to pass through the system until the
cartridge is changed and the meter reset. See
“Changing Filter” for filter replacement procedure.
E. Make Final Tubing Connections
With all of the components in place, the final tubing
connections can be made. When routing tubing
between components, several guidelines should be
observed.
•
Tubing runs should generally follow the con-
tour of the cabinets rather than interfere with
the cabinet storage area.
•
Strive for neatness and an orderly tubing
“flow” using fasteners (e.g. insulated
staples) to secure the tubing. Cut tubing to
the desired length.
•
Arrange the tubing so there are no sharp
bends and leave some “play” in the tubing
for ease of servicing.
•
Try to keep the tubing from the purification
assembly to the tank and faucet as short as
practical for good flow.
F. Install Ice Maker Hookup (optional)
Note: Check with refrigerator manufacturer for
compatibility with your refrigerator model.
The NRS-1 drinking water appliance can be
connected to any standard refrigerator ice maker or
ice maker/water dispenser. It should never be
connected to a commercial type bar ice maker.
Hooking up an ice maker involves connecting a tee
with shut off valve into the faucet tubing and routing
tubing over to the refrigerator.
Before turning off the existing tap water supply to a
refrigerator ice maker, always shut off the ice
maker first (usually by lifting the lever arm above
the bin to the upper most position). The ice maker
should only be turned on again after 1-2 gallons are
flushed through the NRS-1 system.
NOTE: Before any service is performed on the
NRS-1 system, always turn off ice maker valve and
the ice maker unit. Only turn on when system is
operating.
