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 HMX-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 heavy metal water test has been
done and those numbers provided.
The HMX-1 may be installed on waters containing
heavy metals listed in Section I.; however, the total
heavy metal concentration of the incoming water
supply must be less than or equal to 100.0 ppb.
Installing this unit on water with greater than 100.0
ppb of heavy metals may result in harmful heavy
metal bleed through in excess of the MCL
established by the EPA. I.E. arsenic MCL = 10
ppb, lead MCL = 15 ppb, etc.
Set the automatic shut-off meter to the
recommended number of gallons shown on page 3.
See “Changing Filter” for filter replacement
procedure.
E. Make Final Tubing Connections and Install
the Leak Stop Valve
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 filter
assembly to the tank and faucet as short as
practical for good flow.
Securely mount the Leak Stop Valve to the base of
the cabinet below the filter assembly. See III. C. 4.
on page 5 and exploded diagram on page 9.
F. Install Ice Maker Hookup (optional)
Note: Check with refrigerator manufacturer for
compatibility with your refrigerator model.
The HMX-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 HMX-1 system.
NOTE: Before any service is performed on the
HMX-1 system, always turn off ice maker valve and
the ice maker unit. Only turn on when system is
operating.
