Your Dolphin Whole House ltration unit is shipped in (2) separate
boxes. The filter unit is contained in one box and the valve in
another. The Valve box contains the Automatic Valve, Bypass
valve, and an Upper Distributor screen to be attached to bottom
of valve prior to installation. You will need either an 1” or ¾” MPT
adaptor to hook up the pipes to the bypass. Your Automatic valve
will plug into any standard 110V power socket. The automatic
valve has an internal computer that will retain the proper time for
approximately up to 12 hours of power loss. See valve operation
instructions on page 14.

Location of Filter Unit
75
DOLPHIN
The purpose of a point of entry unit is to filter all the
incoming water into the home and therefore should be
installed as close as possible to where the water enters
the home. On municipal water systems the filter should
be located after the water meter and before the water
heater. On well water systems the filter should be located
after the pressure tank and before the water heater.
The lter is to be installed
on the COLD water line only.
Allow 15 feet minimum of piping length between the
filter and the water heater. If this is not possible, install
a check valve in the water supply line between the filter
and the hot water heater to prevent hot water from
backing up into the filter.
To ensure the proper operation, a minimum of
20 psi is necessary. Maximum operating pressure is 120
psi. 100oF is max temp for tank and valve.

DO NOT SUBJECT THE UNIT TO
FREEZING CONDITIONS.
Locate an installation spot where the unit can be installed
so that it can be easily removed for servicing. Avoid trying
to “squeeze” the unit in between the hot water heater and
furnace for example.
This unit must be kept from freezing! If installing outside,
keep the unit from being exposed to direct sun light and
protect valve from the weather as well as keeping it from
freezing.
The valve will require a standard 110V AC outlet to plug
into and a drain access for the back wash drain line
capable of handling a flow of up to 5 GPM.
The back wash drain line can consist of either pipe or
semi-rigid hose and must allow an unrestricted flow to a
drain capable of handling a discharge of up to 5 GPM for
15 minutes. It is recommended to use a drain hose of at
least ½” ID or larger. Drain lines running more than 30 feet
should be of ¾” ID minim. If using soft tubing (vinyl) make
sure not to kink hose so not to reduce ow during backwash.
IMPORTANT
If you purchased multiple tanks and/or Polishing Filter,
follow this installation order:
Connect untreated water rst to:
1. Dolphin Heavy Medal Fluoride
2. Dolphin VOC
3. Polishing Filter (if purchased)

Installation Instructions
Place the tank in the spot you wish to install it. Remove
the black shipping cap from top of filter and then remove
plastic bag/sleeve covering riser tube located inside the
filter. (Plastic bag shipping sleeve is covered with red tape)
Next install the plastic upper distributor onto the bottom
portion of backwash valve. Push the upper distributor into
base and twist clockwise.
BE CAREFUL not to cross thread the valve when installing
it onto tank. A procedure to help prevent cross threading
is to rotate the valve backwards (counter clockwise) while
lowering the valve onto the tank until you can feel the first
threads ”click” over each other then screw valve onto tank.
Use caution to keep the valve straight while lowering onto
the riser tube. By keeping the valve straight while lowering,
you will allow the tube to stay centered on the valve, and
the insertion of the tube up into the valve center body will
be easier. As the riser tube enters the valve body it will be
gripped by an “O” ring located in the bottom of the valve,
where at that time the valve lowering/rotation will feel a
little snug as the valve is lowered toward thread engage-
ment. Once the tank threads and valve threads meet, you
will hear a light click while rotating the valve backwards.
You now may begin to rotate the valve clockwise until it is
hand tight. Do not over tighten.
CAUTION! on installing VALVE onto tank

Next make sure the by-pass valve is securely fastened to the
back of the valve. Take notice to the inlet and outlet markings
(arrows) located on the valve so that it will be plumbed in
properly.
The by-pass valve is clearly marked by two arrows. One arrow
is pointing toward the valve (this is the “IN”) and another is
pointing away from the unit (this is the “OUT). The handle(s)
should be aligned in the same direction as the piping when
water is flowing IN and OUT of the unit – This is also referred
to the “Service” position during filter use and in the “By-Pass”
position during installation and maintenance. In the bypass
position the handles are perpendicular to the water pipe flow.
PLACE BOTH HANDLES IN THE “BYPASS” POSITION PRIOR TO
INSTALLATION.
During the installation process, position the lter where you
want it installed, then measure and modify piping as required.
DO NOT APPLY HEAT TO ANY FITTINGS CONNECTED TO THE
FILTER BYPASS/VALVE. Heat will damage the plastic ttings.
Use only “lead free” solder when soldering copper pipe.
When installing back wash drain line use an air gap procedure
if installing over a floor drain. Use extreme caution if run-
ning drain line into a deep sink as should the sink becomes
clogged/blocked flooding could result. It is recommended to
run drain line into a drain similar to a washing machine drain
standpipe. It is recommended to use a semi-ridged plastic
tubing such as a polyethylene or similar tubing. Vinyl hose is
not recommended as it tends to collapse with age and restrict
the back wash flow. If using PVC or copper pipe for the back-
wash drain line you must install a union on the drain line
near the back of the valve for easy disconnect of the drain line
during servicing.

To Place Tank in Service
After all plumbing is finished (including the back wash
drain line) restore water pressure to home while the
unit bypass valve is still in the “by-pass” position. This
will enable you to insure there are no leaks in the piping
before adding water to the tank.
INITIAL RINSE: Do not run water in any part of the
house during the initial rinse procedure
Next, plug in unit to a nearby 110V/ac outlet. (See page 14
for “QUICK SET UP GUIDE”)
Initiate the backwash on the valve by depressing the
Extra Cycle button for 3-5 seconds.
The valve will cycle into the back wash position cycle
#1 and begin counting down the minutes remaining in
cycle 1. Next slowly open only the inlet valve knob of
the by-pass valve, only to 1/3rd the way open, so that
the water may SLOWLY fill the tank. This procedure
allows the media to hydrate slowly and will take about
15 minutes. You will observe air, water and carbon fines
coming from the drain line.
Immediately after opening the inlet valve 1/3rd of the
way unplug the valve from the wall socket so the unit
will remain in cycle #1 (1st backwash) until it is plugged
back in. If you leave it plugged in it will automatically
move to the next cycle before the filter media is prop-
erly hydrated.

Next plug the valve electrical cord back in and allow the unit
to complete the remaining cycles.
After the last cycle has completed, initiate another complete
back wash by depressing the “Backwash” button for 3-5 seconds
and let the unit run through the complete cycle.
AT THIS TIME OPEN THE OUTLET PORTION OF THE
BY-PASS VALVE SO FILTERED WATER WILL FLOW
INTO THE HOME.
It is not uncommon to experience air and small carbon fines
in your water during the first few days after installation.
Occasionally in systems with high water pressure it is also
not uncommon to experience fines immediately after the
periodic backwash cycle takes place. Should you have a
water system with high water pressure it is recommended
to install our optional 5 Micron Sediment Filter (Part #7504)
after your Dolphin Whole Home Filtration filter. This polishing
filter will trap the fines generated during the backwash cycle.
Should you have any questions pertaining to the installation
of your unit, please call Technical Support at 866.321.3116.
Should you experience a loss of water pressure it is recom-
mended to initiate a backwash by depressing the “extra cycle”
button for 3-5 seconds. This should restore any pressure loss if
the loss is due to the filter becoming clogged. The By-pass
valve is to be kept in the “service” position. Should you ex-
perience any problems with your system you may place the
by-pass valve in the “bypass” position until the problem can
be fixed.

Remember, the Dolphin Whome Home Water System
is designed for the expressed purpose of reducing
taste, order, sediment and various organic chemical
compounds found in the water. Due to varying water
conditions it may be necessary to install additional
water treatment equipment. (iron removal, bacterial
problems, or pH imbalance, for example).
For healthy, clean water it is recommended you have
your water tested annually. Consult your Life Ionizer’s
Water Professional for details.

A Word About Filter Operation:
Incoming water is dispersed initially in the top of the
filter by the upper distributor. The water travels down-
ward through a void area which is called “freeboard”
(approximately 25 - 35% of filter bed depth). The water
then passes through the filter media and is returned up
through the center riser tube and is routed through the
valve to the “out” fitting.

A Word About Back Flush:
Your Dolphin Whole Home Water System is supplied with an
automatic back flush valve. This valve enables you to extend
the life of the media by:
1. The removal of sediment which has been collected.
2. Repositioning the media, which will then realign the
ineffective saturated surface area with a fresh and
effective surface to better remove contaminants.
3. Filter life is not extended by removal of adsorbed organic
material. The “fluffing” action which takes place will not
remove adsorbed organic material since the bonding
process is not distributed by backwashing.
4. The fluffing process (backwash) is controlled by the
backwash assembly valve. It re-routes the water down
the center riser tube and is distributed by the gravel bed
at the bottom of the tank which allows for even
distribution from this reverse flow. The now upward flow
will gently agitate the media thus accomplishing the sed-
iment removal (out through the upper distributor) and the
“re-shuffling” of the media itself. This action is governed
directly by the back flow rate and it is controlled by a
restrictor placed in the backwash portion of the valve.

IMPORTANT- - - Placing the unit in bypass
Should there be a loss of water pressure in your home
caused by the filter, initiate a backwash by depressing the
“extra cycle” button and running a complete backwash
through all 4 cycles. Should this not correct the pressure
loss, place BOTH bypass valve knobs into the bypass posi-
tion and call your water dealer. The two knobs are located
directly behind your automatic valve where your cold
water pipes enter the unit. The knobs will only rotate 90o
from full service to full bypass. If using a tool to assist
turning valves, use caution not to turn the wrong way- you
could damage the bypass valve!
Note:
Placing the bypass valve into the bypass position will
bypass both the filter tank and filter valve. The water
entering the home will no longer be filtered.

Automatic Backwash Valve Quick Set-Up Guide
Your Dolphin Whole Home System’s automatic backwash valve
has four cycles (a double backwash and a double rinse). The
valve control has a “child proof” conguration which requires
the depressing of the required setting button for a 3-5 second
period before being able to change any setting. This feature
prevents “accidental” changing of the settings.
Basic Operations
ABLUE status light indicates all is normal. The LED window
will normally be indicating the “Time of day”.
AGREEN status light indicates when the unit is in a Backwash
(regeneration) mode, unless an error condition exists. (LED will
indicate which cycle is in operation).
A RED status light illuminates when there is an error condition.
For normal day to day valve operation you will see the Blue
light and the LED time of day window will indicate the follow-
ing: “SRV” telling you the valve is “In Service”, the Time of Day,
and how many days until the next “REGEN” (Backwash) will
take place.
If the “time of day” is blinking, it is an indication there was a
power interruption to the valve. The reason the time is blink-
ing is to draw your attention to this fact, and is asking you
to verify that the time displayed on the LED is correct. If it is
correct, press either the up or down button one time. If the
time is not correct, see “Set Time of Day” below. The valve
computer is capable of keeping the correct time of day for up
to 12 hours of power loss. However, the valve itself will not
function without power.

www.LifeIonizers.com 15 75
DOLPHIN
To Set Time of Day
To change the TIME press either the “up” or the
“down” arrow for 3-5 seconds. You then can adjust the time by
pressing the (up) ^ or v (down) button once for each minute
you wish to change. After you set the time, the main display
will automatically reappear in approximately 15 seconds.
When Did the Last Backwash Occur?
The Dwhen pressed will indicate the last two times the valve
completed a backwash cycle. When you first press the Dyou
will get an indication of when the last backwash occurred.
Pressing the after first pressing the D will indicate the pre-
vious backwash. Pressing the D a second time will put the
“Time of Day” display back onto the LED.
To Initiate an Extra Backwash Cycle
Press the “extra cycle” button for 3-5 seconds (keep button
pressed until you see the screen change). The unit will go
through all four cycles; each cycle time is pre-set at the factory.
You may skip a particular cycle by pressing the extra cycle button
any time the unit is in a cycle you wish to skip.
(Cycle (1) =1st backwash - Cycle (2) = 1st rinse – Cycle (3)=2nd backwash -
Cycle (4) =2nd rinse).

To set Backwash Frequency (in DAYS) and Backwash
Time of Day
The Dolphin Whole Home System’s factory valve setting for a
Backwash to occur is once every 10 days with a start time at
2:00 am.
NOTE: IF YOU HAVE TWO OR MORE AUTOMATIC BACKWASH
TREATMENT UNITS: SET THE BACKWASH START TIME SO THAT
THE UNITS WILL NOT BE BACKWASHING AT THE SAME TIME
(e.g. Set UNIT 1 for a 2:00 am start and UNIT 2 for a 3:00 am start).
To Change Backwash frequency (currently set to backwash
every 10 days)
To reset how many days between each backwash and also
to set the time of day that the back wash will take place you
will need to press BOTH the “up” AND the “down”
arrows AT THE SAME TIME for 3-5 seconds (until the
screen changes). You will see a new screen which says
“REGENERATION DAY OVERIDE” and “10 DAYS”. Press-
ing either the up or down button will increase or decrease
the number of days between automatic backwashes.
To Change Backwash Time of Day
To change backwash time you must do so while you are
still in the “REGENERATION DAY OVERIDE”. While you are
in the “REGENERATION DAY OVERIDE” setting press the
“EXTRA CYCLE BUTTON . This brings up the backwash
time. You then may change the backwash time by pressing
either up ^ or v down arrow to change the time of day the
unit will backwash.
