B. UNPACKING
Check label located on outside of tank carton
against cartons received. The large carton
contains the filter tank, gravel and manifold
valve. Mineral is packaged separately.
C. LOCATION
For complete customer satisfaction, all water
in the home should be filtered, with the
exception of the outside faucets. Select a
location near the water service inlet. On a
private system, locate the filter after the pres-
sure tank.
D. INITIAL MINERAL FILLING
The tank must be loaded with mineral after
being placed at the desired location. The filter
tank can be loaded through the mineral tank
plug. Place a funnel in plug hole. Pour sever-
al gallons of water in the tank. Next pour in
the mineral. The required quantity is shown
on the specification Chart A.
Fill tank with water by using a garden hose
or several buckets of water. This will permit
the mineral to become soaked while finish-
ing the installation. Replace the tank plug.
Tighten snugly.
E. WATER SUPPLY CONNECTIONS
Inlet and outlet connections are 3/4” NPT for
UN10 and 1" NPT for UN20 and are marked
on the valve manifold. See installation dia-
gram. Turn off the water supply and connect
the supplied installation hoses, one end to
the manifold valve and the other end to the
plumbing. Connect the remaining optional
valves and fittings as shown in Illustration A.
Install the recommended in-line strainer. This
strainer is optional and not provided with the
equipment.
F. STARTING THE UNIT
Close by-pass valve and open outlet valve.
Also open a cold water faucet after the filter.
Remove the strainer on faucet aerator if pres-
ent. Slowly open the inlet valve to fill the
mineral tank. Air will be expelled out the cold
water faucet. Allow water to run out faucet
for 10 minutes or until water clears.
CARBON UNITS ONLY: Initially, the water
will be black from the carbon fines. It takes
carbon a day or two to “wet out”, so periodic
black color may appear during this time, par-
ticularly when water is run at a high flow.
Close faucet and open inlet faucet fully.
Replace the faucet aerator screen if removed.
Check this screen if pressure drop or low
flow is noticed during the first few days.
IMPORTANT: At start up, new mineral will
entrain air into the water stream. This can
cause the water to have a milky appearance.
This is a normal, harmless condition that
should last no more than a few days,
depending on water usage.
