WaterTech REIONATOR PRO ULTRA RXU13 Manual

WHOLE HOUSE WATER CONDITIONER
with Triton Electronic Control Valve
INSTALLATION AND SERVICE MANUAL
IAPMO R&T certied to NSF/ANSI Standards 42 and 44
for meeting or exceeding industry standards of aesthetic
chlorine reduction and softening efciency.

IMPORTANT: Optimum sizing of the Reionator Pro Ultra™will result in a regeneration every 3 to 6 days.
IMPORTANT: Do not use with water that is microbiologically unsafe or of
unknown quality without adequate disinfection before or after the system.
PLUMBING CONNECTIONS
In virtually all circumstances, the Reionator Pro Ultra™ water system is at-
tached to the main incoming water line in the home (hereafter referred to
as the “main water line”) and conditions both the hot and the cold water
lines—including lines to drinking water and ice machine lines. Be sure you
are hooked up to the main water line and are feeding back into the main water
line which branches off to all other lines. Refer to the Plumbing Connection
Diagram (Figure 5, Page 5) for typical conguration.
IMPORTANT: Ensure that water entering the Reionator Pro Ultra™ is from
the main cold water line, especially if the Reionator Pro Ultra™ is not the rst
appliance in the plumbing line. Hot water entering the REIONATOR™ may
damage the resins and will void the warranty.
SYSTEM CAPACITY & REGENERATION SETTING
Refer to Table 1 to determine the volume of water that can be conditioned by
the size of the system you have installed. This capacity may be different from
ordinary softening systems, so please check the numbers.
If the valve is a timed valve, it regenerates at a predetermined number of days.
To calculate the number of days, divide the total capacity of the system (optimum
grains capacity divided by water hardness) by gallons per day (# of people times
75/gallons/person/day). For example, there are 4 people in a home and you are
installing a 32,000 grain Reionator Pro Ultra™ (which has an optimum capacity
of 16,080 according to the chart).
As an example, say you’ve tested the water and it has a hardness
of 7 grains/gallon.
Optimal grains capacity ÷ water hardness = total capacity.
No. of people x 75 gallons per day = gallons/day.
Total capacity ÷ gallons per day = No. of days to regenerate.
16,080 ÷ 7 = 2,300 gallons total capacity.
4 x 75 = 300 gallons per day water usage.
2300 - 300 gallons = 2000 gallons reserve capacity.
Reserve capacity = working capacity.
2000 ÷ 300 = 6.67 days before regeneration.
If the valve is a metered valve, which measures actual water use, then using
the above example, the setting would be about 2,000 gallons (allowing for a
reserve capacity of approximately one day of water use). 2,300 gallons (total
capacity) - 300 gallons per day (one day’s use) = 2,000 gallons.
IMPORTANT: As with any other appliance ALWAYS check your state and local
regulations regarding plumbing and electrical connections and placement of the
system before installation.

SALT SETTING
Refer to the tables on the previous page to determine the
correct setting for the size system you are installing. This
setting may be different from ordinary softening systems, so
please check the numbers.
VALVE ASSEMBLY
The Triton control valve comes with a noryl plastic bypass valve
which simplies installation and is convenient to use should
the system need to be serviced in the future. Inlet and Outlet
connections are 3/4" or
1" pipe size.
PLACEMENT OF THE
REIONATOR PRO ULTRA™WATER SYSTEM
Install the Reionator Pro Ultra™ system into the existing cold water
supply line before the water heater and before any cold water outlet that
requires treatment. When selecting a location for the system, please keep
the following things in mind:
1. Choose a location that requires the least amount of piping. While this
is important from a cost standpoint, it is more important that the distance
between the Reionator Pro Ultra™ and the drain be as close as possible.
2. An approved 115/120 volt 60-cycle grounded receptacle should be
within reach of the 15 ft. transformer power pack.
3. Since salt or potassium chloride must be periodically added to the brine
tank, the location should be easily accessible.
4. All systems are designed to be installed in an inside and weather-
protected location. However, in a few states where climate conditions
allow, systems may be installed outside. If the system is installed outside,
it must be sheltered from rain and direct sunlight.
IMPORTANT: Damage to the Reionator Pro Ultra™ as a result of
exposure to the elements without the use of a weather cover will not be
covered under the limited lifetime warranty.
5. In some situations supplementary water treatment may be required
(sediment lter, iron removal, etc.). Make certain that adequate space is
available.
6. Outside faucets should be on the untreated hard water line in front of
the Reionator Pro Ultra™ system. Conditioned water is not needed for lawn
or garden watering. (The hose bib closest to the garage may have treated
water for washing cars.)
7. Do not locate the system where it or its connections (including the drain
and overow lines) will ever be subjected to temperatures under 40° F
(4.4°C) or over 110°F (43.3°C).
8. Select a location where the oor is level. If the oor is rough or uneven,
level it by placing the resin tank on 3/4" exterior plywood. Cut 1" larger on
all sides and then shim to level as needed.
9. Do not install any system close to a hot water heater with less than
a total run of 12 ft. of piping between the outlet of the Reionator Pro
Ultra™ system and the inlet to the heater. Water heaters can sometimes
overheat to the extent they will transmit heat back down the cold water
pipe into the Reionator Pro Ultra™ control valve. Hot water will severely
damage this equipment. (See plumbing connection diagram Fig. 5, Page 5).
Elbows, bends and straight pipe totalling 12 ft. will meet this requirement.
If necessary to place closer, install an approved check valve between the
discharge on the Reionator Pro Ultra™ and the inlet of the water heater.

Installation
MOVING THE REIONATOR PRO
ULTRA™INTO POSITION
Keep the Reionator Pro Ultra™ resin tank upright and
move it into position. (The resin tank should always
be upright, even during storage and while being
transported to the site.) Level the system with shims.
Make sure the bypass valve or manifold is attached. At
this point, measure the piping required. Make sure that
the measurements allow for ttings.
BEFORE CUTTING
Shut-off the heat (gas or electricity) to the water heater.
Shut-off all water at the main supply valve. Drain the
piping by opening the highest faucet in the plumbing
system and the lowest faucet or drain plug. When the
pipes are drained, install the inlet and outlet piping to the
Reionator Pro Ultra™ control valve.
When the Reionator Pro Ultra™ is installed, move the
lever on the direct connect bypass valve to the bypass
position. On a three valve bypass system, close the inlet
and outlet valve and open the bypass valve. Water can
now be restored to the building during the rest of the
installation. Check for leaks and correct, if found.
DRAIN LINE CONNECTION
Install 1/2" I.D. plastic tubing from the hose barb located
on the right side of the main control valve to an open
drain. Do not connect the drain directly to a sewer
as this would violate sanitary codes. (See Figure
4a) If the drain line is extremely long, or discharges
above the main control valve, a back pressure may limit
the effectiveness of the injector, drawing brine during
regeneration. A siphon trap (a simple knot or taped loop)
at the outlet of the drain line is advisable to keep the drain
line full and assure correct ow during regeneration. (See
Figure 4b)
Where the drain line is elevated above the valve
and exceeds 20' in length, a 3/4" I.D. drain line is
recommended. Elbows or other ttings in the drain line
must be kept to a bare minimum. Installation should never
allow for rinsing of brine through water supply lines.

BRINE LINE CONNECTIONS
On all units, 3/8” O.D. x 1/4” I.D. brine line tubing must be
assembled at both the system control valve and the brine valve as
shown. The tubing is included in the brine tank.
Make sure the nylon insert is inside the ends of the plastic tube
when making the connection. Tighten up the compression nuts
rmly (tapered edge faces towards valve).
OVERFLOW CONNECTION
Install 1/2” I.D. tubing (not provided) to the brine tank overow tting
located on the side of the tank and run it to the drain. The brine
overow is provided in case a situation should arise causing too
much water to be added to the brine tank. This drain connection will
carry the excess to the drain and prevent ooding of the oor. No
liability will or can be assumed by the manufacturer of the Reionator
Pro Ultra™ system should ooding occur (See Figure 5).
Install the brine overow tubing even if the brine tank used with
your Reionator Pro Ultra™ includes a safety brine valve as a product
feature.

FUNCTION AND CYCLES OF OPERATION
This glass-lled Noryl1 fully automatic control valve is designed as the primary control center to direct and regulate all cycles
of a water softener or lter. When the Triton is set up as a softener, the Triton can be set to perform down ow or up ow
regeneration. When the Triton is set up as a lter, the Triton can be set to perform down ow regeneration or simply backwash.
The Triton can be set to regenerate on demand (consumption of a predetermined amount of water) and/or as a time clock (passage
of a particular number of days). The Triton can be set so that a softener can meet the NSF International efciency rating.
The Triton is compatible with a variety of regenerants and resin cleaners. The Triton is capable of routing the ow of water
in the necessary paths to regenerate or backwash water treatment systems. The injector regulates the ow of brine or other
regenerants. The Triton regulates the ow rates for backwashing, rinsing, and the replenishing of treated water into a regenerant
tank, when applicable.
The Triton is designed to deliver high service (27 gpm @ 15 psig) and backwash (27 gpm @ 25 psig) ow rates when the bypass
has straight ttings. The Triton uses no traditional fasteners (e.g. screws), instead clips, threaded caps and nuts and snap type
latches are used. Caps and nuts only need to be rmly hand tightened because radial seals are used. Tools required to service the
valve include one small blade screw driver, one large blade screw driver, pliers and a pair of hands. A plastic wrench is available
which eliminates the need for screwdrivers and pliers. Disassembly for servicing takes much less time than comparable products
currently on the market. Triton installation is made easy because the distributor tube can be cut ½” above to ½” below the top
of tank thread. The distributor tube is held in place by an o-ring seal and the Triton also has a bayonet lock feature for upper
distributor baskets.
The transformer power pack comes with a 15 foot power cord and is designed for use with the Triton. The transformer power pack
is for dry location use only. The Triton remembers all settings for two hours if the power goes out. After two hours, the only item
that needs to be reset is the time of day, all other values are permanently stored in the nonvolatile memory. The Triton does not
need batteries.
Table 2 shows the order of the cycles when the valve is set up as a softener. When the Triton is used as a down ow softener,
two backwashes always occur.

FLUSHING, CONDITIONING AND SANITIZATION
Step 1. Make sure the system is in the “Bypass” position before turning the main water back on (see gure 12a above).
Make sure the drain line is connected securely to the control valve and is properly located over a drain.
Make sure the drain line is connected to the overow elbow (see gure 6, page 7) and is properly located over a drain.
Make sure the brine line is connected to both the air check in the brine well and the control valve. (see gure 7, page 7)
Make sure the control valve is plugged into an operating outlet with the correct voltage and is properly grounded.
Step 2: Press and Hold the REGEN button on the Triton until you hear the motor engage. This will initiate an immediate manual regeneration
of the system. Refer to the table on page 10 for Triton cycles of operation. Turn the bypass valve to Normal Operation (gure 12b
above) (you should hear water entering the system.) Wait a few minutes to ensure the control valve can draw water and does not
leak. If everything is working, press and release the REGEN button. You will hear the motor engage and move the piston into the
“Brine Dn” position. Check the brine line for leaks or suction. You should hear the valve drawing brine. Continue to skip cycles by
pressing and releasing the REGEN button (wait for the motor to stop before pressing REGEN) until you reach the “Brine Fill” position.
This ensures that water will go to the brine tank. Fill tank 3” to 4” above salt grid. Make sure enough water is in the brine tank to
dissolve the correct amount of salt for regeneration (1 gallon of water will dissolve 3 lbs. of sodium chloride). Allow the brine tank to
ll with water to air check level. If the system needs 6 lbs. of salt to regenerate, then at least 2-1/2 gallons of water must be in the
brine tank above air check in the brine well. The extra 1/2 gallon is an additional measure for evaporation or loss. (6 ÷ 3 = 2 gallons of
water plus 1/2 gallon). Fill the brine tank with salt. (We recommend potassium chloride (KCl) instead of rock salt.) Once the brine tank
is lled to this level, press REGEN once more to return the valve to service. You should hear the motor engage for a short period and
then a long period.

Step 3: To ensure sanitary conditions in the mineral and brine tanks, place 1.5 ounces common household bleach into the brine tank. Press and
hold the REGEN button for 3 seconds to move the control valve into “1st Backwash” position. Once the motor stops, press and hold the
REGEN button to move the control valve to the “Brine Dn” position. This cycle normally takes about 60 minutes, however 10 minutes
should be sufcient to pull the chlorine from the brine tank. After 10 minutes, press and hold the REGEN button to move the control valve
to the “2nd Backwash” position. Let the valve complete this cycle and also the “Brine Rinse” and “Brine Fill” cycles which will come
next. Once the valve has completed the “Brine Fill” cycle it will automatically return to service. In step 5 you will set the valve to “Regen
Today” so that it will regen tonight at the specied time. If there is any residual chlorine, it should be removed tonight.
Step 4: Make sure that the bypass valve is completely set in the “Normal Operation” position. Let the water in the taps of the building run for
several minutes to purge the unconditioned water out of the pipes. After several minutes, take a water sample and test for hardness
from the running tap. If a hardness test reads “soft” water then the installation is correct
Step 5: Press and release the REGEN button. You should see “Regen Today” appear on the LCD screen. This will instruct the control valve to
regenerate tonight at the specied time (usually after everyone is asleep).
Step 6: Drain hot water heater and let it rell with conditioned water. We suggest draining the hot water by turning on the hot water taps in
the house. We recommend doing this just prior to bedtime.

14
Step 1. To set the hardness on your Triton control valve, press the NEXT and buttons simultaneously. You
will see the display change from the time of day to the “Set HARDNESS” screen as above. Simply press
the or to change the grains per gallon of hardness.
SETTING HARDNESS, REGENERATION DAY AND REGENERATION TIME
The Triton control valve on your Reionator Pro Ultra™ comes pre-set from the factory to perform as a typical softener
valve. However, there are certain settings that are specic to the customer’s water situation that cannot be set at
the factory. This section will guide you through these settings.
Setting Up The Triton Valve
IMPORTANT: Please be sure you know your water hardness before setting this screen. A hardness setting that is too low will result in depleted capacity
and water that is not softened. A hardness setting that is too high will result in more frequent regeneration and increased salt usage.

Step 3. From the “Set REGEN DAY” screen, press the NEXT button. You should now see the “Set REGEN TIME” screen
(shown above). Simply press the or button to change the time of day, on the regeneration day set in the
previous step you wish your REIONATOR™ to regenerate. Normally 2:00 AM is appropriate for most situations.
Step 2. From the “Set HARDNESS” screen, press the NEXT button. You should now see the “Set REGEN DAY” screen
(shown above). Simply press the or button to change the day override.
IMPORTANT: This screen is used
to set the day override to force
regeneration on the specied number of
days since last regeneration regardless
of water usage. Changing this setting is
usually not necessary.
IMPORTANT: During regeneration,
hard (raw) water will exit the system.
Be sure that the regeneration time is
set during the night when NO water
is used.

GENERAL SERVICE HINTS FOR METER CONTROL
Problem: Softener delivers hard water
Hard water delivered from the Reionator Pro Ultra™ may indicate that the unit has exceeded it’s reserve capacity.
Correction: Check your water hardness and make sure that you have set the hardness correctly. Hardness set too low will cause
your Reionator Pro Ultra™ not to regenerate often enough.
Correction: Check to ensure a good connection from the meter to the PC board on the Triton. Check for loose or broken wires
and reconnect to the PC board if necessary.
Correction: Check the meter turbine to ensure that it rotates freely. Check for foreign matter in the meter shaft. Replace meter
if necessary.
Correction: From the time of day screen on the Triton, press the NEXT button to see the softener usage. If there is a tap or hose bib nearby
that is connected to the system, place a 5-gallon bucket underneath and ll it. Check the capacity remaining to see if it has
decreased by 5 gallons. If not, replace the meter. If replacing the meter does not solve the problem, replace the PC board.
