INSPECTION, MINERAL LOADING AND ASSEMBLY
Commercial water filters are shipped in multiple cartons:
- mineral tank with bottom distributor and riser pipe
- control valve
- optional alternator valve or no hard water bypass valve
- bag(s) of gravel support bed (for 21" diameter and larger mineral tanks)
- bags of water mineral
Quantity of components are specific for the individual type filtering system ordered. Refer to specification
data sheet and/or drawing or consult factory.
Inspect the shipping cartons and equipment for possible shipping damage or lost parts. If damage is present,
notify the transportation company. The manufacturer is not responsible for damage or lost parts in shipment.
Do not mistakenly discard any small parts bags when unpacking the system.
BEFORE LOADING THE MINERAL TANK WITH GRAVEL FOLLOWED BY MINERAL,
INSPECT THE BOTTOM LATERALS FOR ANY DAMAGE THAT MAY HAVE OCCURRED DURING SHIPPING.
THE LATERALS MUST BE REPLACED IF THERE IS ANY DAMAGE.
LOADING AND ASSEMBLING THE MINERAL TANK:
1. Place the mineral tank where you want to install it, making sure it is
on a clean, level and firm surface.
2. PLUG OR TAPE THE TOP OF THE RISER PIPE to keep gravel
and mineral from entering. Gravel and mineral must not enter riser pipe.
3. BEFORE LOADING THE GRAVEL AND MINERAL, FILL THE
MINERAL TANK APPROXIMATELY 1/3 FULL OF WATER.
The water will act as a cushion to protect the bottom laterals from
damage while filling the tank with gravel and mineral.
4. Using a U1007 commercial tank funnel is recommended (funnel is
ordered separately). The U1007 funnel snaps into 4" and 6"
mineral tank openings for stability when pouring gravel and mineral.
The neck of the funnel allows air to escape the mineral tank while
gravel and mineral are poured in.
5. Load the gravel support bed first, followed by the mineral. While filling,
be careful to keep the riser pipe centered as best you can.
Filling slowly with a small scoop to pour the mineral into the funnel,
using water SPARINGLY to speed flow through the funnel if necessary,
will work better than trying to fill too fast.
6. After the loading is complete, remove the funnel, clean the tank
opening to remove mineral granules from the tank opening. Note that
the mineral will only fill the mineral tank approximately 1/2 to 3/4 full.
The mineral tank should NEVER be filled to the top with mineral.
This remaining open space is called freeboard and is necessary for the
mineral to have room to move during the backwash cycle.
7. REMOVE THE PLUG OR TAPE FROM THE TOP OF THE RISER
PIPE.
8. FINISH FILLING THE MINERAL TANK WITH WATER. This will
eliminate air space and prevent excessive air-head pressure when
the water filter is pressurized.
9. The control valve must now be screwed onto the mineral tank.
Be sure the mineral tank's o-ring sealing surface is clean. NO pipe
dope should be used on threads. As you start to screw the control
valve onto the tank, make sure the hole in the center of the control
valve fits over the riser pipe. The control valve should be hand-
tightened, snugly, clockwise.

The control valve and ttings are not designed to support
the weight of the system or the plumbing.
Do not use Vaseline, oils, other hydrocarbon lubricants or
spray silicone anywhere. A silicone lubricant may be used
on black o-rings but is not necessary. Avoid any type of
lubricants, including silicone, on the clear lip seals.
Hydrocarbons such as kerosene, benzene, gasoline,
etc., may damage products that contain o-rings or
plastic components. Exposure to such hydrocarbons
may cause the products to leak. Do not use the
product(s) contained in this document on water
supplies that contain hydrocarbons such as kerosene,
benzene, gasoline, etc.
The optional water meter should not be used as the
primary monitoring device for critical or health e󰀨ect
applications.
Do not use pipe dope or other sealants on threads. Use
of pipe dope may break down the plastics in the control
valve. Use Teon tape on the threaded inlet, outlet and
drain ttings.
After completing any valve maintenance involving the
drive assembly or the drive cap assembly and pistons,
unplug power source jack from the printed circuit board
(black wire) and plug back in or press and hold NEXT
and REGEN buttons for 3 seconds. This resets the electronics
and establishes the service piston position. The display
should ash the software version and then reset the valve
to the service position.
Solder joints near the drain must be done prior to
connecting the drain line ow control tting. Leave at least
6” between the drain line control tting and solder joints
when soldering pipes that are connected on the drain
line control tting. Failure to do this could cause interior
damage to the drain line ow control tting.
Install grounding strap on metal pipes.
This water lter is not to be used for treating water
that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after
treatment.
GENERAL INSTALLATION
AND SERVICE WARNINGS
PRE-INSTALLATION
REVIEW
This water lter is not to be used for treating water
that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after
treatment.
WATER PRESSURE: Maximum 125 psi. CAUTION:
the lter cannot be subject to a vacuum due to loss of
pressure (such as a water main break or submersible well
pump check valve failure).
WATERTEMPERATURE:Therangeofwatertemperature
is 40°F to 110°F. DO NOT install any water lter with less
than 10 feet of piping between its outlet and the inlet of a
water heater.
AMBIENT TEMPERATURE: DO NOT locate lter where it
or its connections (including the drain and overow lines)
will ever be subject to room temperatures under 40°F.
ELECTRICITY: An uninterrupted 120 volt 60Hz outlet,
within 15 feet of the lter, is required. Make sure electrical
source is not on a timer or switch. All electrical connections
must be connected according to local codes. The plug-in
transformer is for dry locations only. Surge protection is
recommended with all electrical connections.
DRAIN: All plumbing should be done in accordance with
local plumbing codes. The distance between the drain and
the water lter should be as short as possible. Correctly
size drain line for the control valve’s drain line ow control
GPM rating (see installation instructions). Avoid elevating
the drain line above the control valve where possible (see
installation instructions).
BYPASS: A bypass valve should be installed so that
water will be available if it should be necessary to shut o󰀨
the pressure in order to service the lter.

BYPASS VALVE
Normal Operation: Water ows through the control valve during service and also allows the control valve to isolate the
media bed during the regeneration cycle.
Bypass Operation: The control valve is isolated from the water pressure contained in the plumbing system. Untreated
water is supplied to the plumbing system.
Diagnostic Operation: Water pressure is allowed to the control valve and the plumbing system while not allowing water
to exit from the control valve to the plumbing system.
(valves shown with optional meters)

PAGE 6
(All electrical & plumbing should be done in accordance to all local codes)
1. LOCATION: Place the lter where you want to install it, making sure it is on a clean, level and rm surface. The plug-in
power adaptor is for dry locations only. Use an uninterrupted electrical outlet installed within 15 feet of the lter. Locate the
lter so the distance between the drain and the lter is as short as possible. Do not install the lter with less than 10 feet of
piping between its outlet and the inlet of a water heater. Do not locate the lter where it or its connections (including the drain
and overow lines) will ever be subject to room temperatures under 40°F.
2. INLET/OUTLET: Connect to a supply line downstream of outdoor spigots. Install an inlet shuto󰀨 valve and plumb to
the unit’s inlet located at the left front as you face the unit. Installation of a bypass valve is recommended. If using plastic
ttings ground the water lter per local electric codes. If a water meter is used, install the water meter on the outlet side
of the control valve. It is recommended that the meter assembly be installed horizontally or in a downow vertical position
to reduce turbine bearing wear. The turbine assembly may be oriented in any direction, but is usually oriented pointing up
to reduce drainage out of the pipes during service. Remove the cover and drive bracket and thread the water meter cord
through the hole in the back plate. Reinstall the drive bracket. Weave the cord through the hooks on the right hand side of
the drive bracket and connect the end to the three prong connector labeled METER on the printed circuit board. Replace
the cover.
3. A jumper ground wire should be installed between the inlet and outlet pipe whenever the metallic continuity of a
water distribution piping system is interrupted. Install grounding strap on metal pipes.
4. DRAIN: The drain must be able to handle the backwash rate of the lter. Correctly size the drain line for the lter’s drain
line ow control gpm rating. An adapter tting is supplied with the valve that can connect a 3/4” tting to be used with drain
line ow controls up to 10 gpm, a 1” tting to be used with drain line ow controls up to 25 gpm, or a 1-1/2” tting to be used
with drain line ow controls up to 60 gpm. If soldering, joints near the drain must be done prior to connecting the drain line
ow control tting. Leave at least 6” between the drain line control tting and solder joints when soldering pipes that are
connected on the drain line control tting. Failure to do this could cause interior damage to the drain line ow control tting.
Avoid elevating the drain line above the control valve where possible. Never insert a drain line directly into a drain, sewer
line, or trap. Always allow an air gap between the drain line and the wastewater receptacle to prevent the possibility
of sewage being back-siphoned into the lter.

*Any V3162-XXX ow control may be used. WS2 valves are
shipped with a V3162-022 (2.2 gpm) ow control. Flow control
sizes range from 0.7 up to 10 gpm. WS2 valves can only be set for
minutes of ll because various sizes of ow controls can be used.
To calculate for pounds or kilograms of salt, take minutes of ll
times the ow rate of the ow control being used to arrive at the
number of gallons of water be added to the brine tank. Each gallon
of water will dissolve approximately 3 pounds of salt.
**Use of H4915 may severely reduce brine draw rates.
