Sun Tap Water Systems

MAIN COMPONENTS
Your water treatment system is a point of entry (POE) system composed of three components:
A. The control valve and computer assembly
B. The fiberglass tank assembly including the water treatment medium
C. The brine tank assembly including brine valve
Each of these assemblies has a specific function as described below:
Control Valve Assembly…Automatically monitors water usage patterns, initiates regeneration
and moves the valve through the steps of regeneration.
Media Tank Assembly… A fiberglass vessel, which contains the water softening media, in the
proper diameter and depth of the media and evenly distributes the feed water throughout
the media tank assembly.
Brine Tank Assembly…A polyethylene vessel, which is used to dissolve salt and to hold the
proper amount of brine for the next regeneration. A brine valve keeps the control valve
from drawing air into the system.
STEPS OF OPERATION
Service…Hard water flows downward through the water softening resin where the hardness minerals,
calcium and magnesium, as well as dissolved iron, are removed from the water and are collected
on the resin. The amount of resin and the salt dosage gives resin a certain capacity for hardness
and iron removal.
Backwash 1 …During the cycle the water flows upward through the resin bed and washes collected
sediment or other foreign material to the drain.
Brine and Rinse…The brine solution is drawn from the brine tank and slowly flows downward through
the resin collecting the hardness and iron as it goes. The brine carries the hardness and iron with it
and rinses them to the drain.
Backwash 2 …Same as backwash 1 above but of slightly shorter duration.
Fast Rinse…Water flows downward through the resin and to the drain carrying with it the remaining traces
of brine.
Brine Tank Refill…A predetermined volume of water flows into the brine tank and dissolves a calculated
amount of salt creating brine for the next generation. This occurs at the onset of the next Service
cycle. Be sure that there is always undissolved salt remaining. Since the frequency of regeneration
is reasonably consistent, a regular addition of salt should be scheduled. Approximately 6"-8" of
salt must be in brine tank. In some cases the installation technician may decide a pre-brine refill
may be appropriate. If so brine refill will occur 2 hours prior to regeneration and will result in
minimal water in the brine tank assembly during service position.
Total Regeneration Time (Backwash 1 through Fast Rinse) can be anywhere between 57 and 107 minutes
depending on setting made for certain water conditions.
NORMAL OPERATING DISPLAYS
GENERAL OPERATION
When the system is operating one of two displays will be shown.
Pressing NEXT will alternate between displays. One of the displays is the
current time of day. Depending on the system’s configurations, the second
display is one of the following: days remaining or gallons remaining. Days
remaining is the amount of days left before the system goes through a
regeneration cycle. Capacity remaining is the number of gallons that will
be treated before the system goes through a regeneration cycle. The user
can scroll between the displays using NEXT.
If the system has called for a regeneration that day, regeneration will
occur at the preset time of regeneration, the words REGEN TODAY will
appear on the display.
When water is being treated (i.e. water is flowing through the
system) the word “Softening” or “Filtering” flashes on the display.
REGEN TODAY will
show if a regeneration
is expected “Tonight”.

GENERAL CARE AND MAINTENANCE INFORMATION
The following guidelines are recommended for you to obtain maximum efficiency from your water
treatment system:
1. Control Valve… Try to keep free of dirt and debris both on valve body and under cover. No
lubrication is required.
2. Brine Tank … A major cleaning is recommended every two years. This interval may need to be
adjusted depending on the amount of insoluble material in the salt being used.
A. Allow salt level to become very low so there is little to remove. Scoop out undissolved salt.
B. Disconnect and remove brine valve. There is no pressure or suction on this line except during
a regeneration.
C. Remove internal parts of brine tank, if any.
D. Clean brine tank interior with a mild cleaning agent (dish soap) and rinse thoroughly.
E. Replace brine valve and internal parts.
F. Pour five gallons of water (softened if available) into the tank (Add only two gallons if pre-
brine refill option is used).
G. Add salt.
H. Replace cover.
I. Allow two hours for concentrated brine to be made before next regeneration.
J. It is recommended that… a manually initiated regeneration should be started now. See
Manual Regeneration.
3. Salt / Potassium Supply…For continuous treated water, the brine tank must have an adequate
supply of salt at all times. This requires checking and refilling at regular intervals, to at least keep
between 6" – 8" of salt and 12" of potassium in the tank. Although your system is designed to
work with all types of salt, recommend pellet salt for outside installations. If usage is less than 50
lbs. a month, do not fill over half full of salt or potassium.
4. Resin Cleaning… All water contains contaminants which depending on their specific nature and
on the amount of water used, will adhere to the spherical resin beads, thereby reducing the
available surface area and the resin’s effectiveness to soften water. This is particularly true if iron
is present in the water. Without a periodic cleaning, the life expectancy and performance of the
resin may be reduced. Therefore it is recommended that a resin-cleaning agent be used once per
year unless the water is a city supply with no iron. If the iron level is very high, the resin may
require an automatic resin cleaning solution to be dispensed to brine solution and will need to be
checked and maintained during monitoring of salt usage. See directions on refill solution or
dispenser in brine tank.

5. Vacations…Your water softener regenerates after a preset volume of water is used or after fourteen
days have passed. Unless you are going on an extended trip, it’s best to allow the regeneration to
take place after fourteen days. If water will not be used for an extended period of time or if there is
a concern about having the system regenerate in your absence, then place the handles of the
bypass valve in the “BYPASS OPERATION” mode as shown below. Also use this mode When
Untreated Water is Desired. It is not necessary to unplug water conditioner when water is turned
off or on bypass.
(Can be used as soft water turn-off during
extended periods when the home is not
being occupied.)

6. Protection from Weather…Water inside your control valve, resin tank, or brine tank must not
freeze. Like any other part of your plumbing system, these pipes, tubes or valves can burst and
leak if allowed to freeze. Electronics should be protected from any sunlight with the optional
cover, which should be provided if necessary by installer.
7. Power Failure…If there is power failure or if the system is unplugged for less than two hours, all
settings including the time of day will be retained in the system memory. If there is a power
outage or the wall transformer are disrupted for greater than two hours, the time of day will flash
and requires resetting. The nonvolatile EEPROM memory will retain all other factory, dealer and
installer settings.
8. Set Time of Day…
TIME OF DAY
Time of day should only need to be set after extended power
outages or when daylight saving times begins or ends. If an
extended power outage occurs, the time of day will flash on
and off indicating that the time should be reset.
STEP 1- Press SET CLOCK
STEP 2- Current Time (hour): Set the hour of day using ∇
or ∆buttons. AM/PM toggles after 12. Press NEXT to go to
step 3.
STEP 3- Current time (minutes): Set the minutes using ∇or
∆buttons. Press NEXT to exit Set Clock. Press REGEN to
return to previous step.
9. Manual Regeneration…Sometimes there is a need for regeneration before the control valve calls
for it usually referred to as “manual regeneration”. This is needed when a period of heavy water
usage is anticipated or when the system has been operated without salt.
- To initiate a manual regeneration at the present
delayed regeneration time (usually around 2:00
a.m.), press and release “REGEN”. The
words “REGEN TODAY” will flash on the
display to indicate that the system will regen-
erate at the present delayed regeneration time.
- If you pressed the “REGEN” button in error,
pressing the button again will cancel the command.
- To initiate a manual regeneration immediately, press and hold the
“REGEN” button for three seconds.
The system will begin to regenerate immediately. This command cannot be canceled.
10. Error Display…If the word “ERROR” and a code number for instant: (Example 1003) appears in the
display, contact the dealer or manufacturer for help. This indicates that the control valve is not able to
function properly and the code number 1003 is the general nature of the problem. Contact your dealer for
service.
11. Drain Line…Any crimping, freezing, or blocking of this line will cause a malfunction of your water
treatment system. Check occasionally.
REGEN TODAY will
show if a regeneration
is expected “Tonight”.

GENERAL INSTALLATION & SERVICE CAUTIONS
The control valve, fittings, and/or bypass are designed to accommodate minor plumbing
misalignments they are not designed to support the weight of a system or the plumbing.
Do not use Vaseline, oils, other hydrocarbon lubricants, or silicone spray anywhere. Do not use
silicone on red or clear lip seals.
Do not use pipe dope or other sealant on threads. Teflon tape must be used on the threads of
the 1" NPT elbow, its ¼" NPT connections, and on the threads for the drain line connection.
Teflon tape is not used on the nut connections or caps because o-ring seals are used. The nuts and
caps are designed to be unscrewed or tightened by hand or with the special plastic Service
Wrench, CLV-V3193. If necessary, pliers can be used to unscrew the nut or cap. Do not use a
pipe wrench to tighten nuts or caps. Do not place screwdriver in slots, on caps, and/or tap with
a hammer.
SITE REQUIREMENTS
-Water Pressure, 20-125 psi -Current draw is 0.25 amperes
-Water Temperature, 40º-110º F -A 15 ft. power cord is furnished
-The tank should be on a firm level surface -The plug-in transformer is for dry locations
-Electrical: Use a 115/120V, 60Hz uninterrupted only.
outlet. -Batteries are not used.
1. The distance between the drain and the water conditioner should be as short as possible.
2. Since salt must be periodically added to the brine tank, the tank should be located where it is easily
accessible.
3. Do not install any water conditioner with less than 10 feet of piping between its outlet and the inlet of a
water heater.
4. Do not locate unit where it or its connections (including the drain and overflow lines) will be subjected
to temperatures at or below 34ºF.

WHAT TO DO BEFORE CALLING FOR A REPAIR
If you suspect that your water treatment system is not working properly, the following routine check should
be made before calling for repair. This may save you time and possibly the cost of a service call.
1. Check for softness with the test kit given to you at time of installation.
2. Brine Tank…If not enough salt, add salt or call for a salt delivery. If dirty, clean as described under
GENERAL CARE & SELF-SERVICE information.
3. Electrical Connection…Be sure that the plug-in wall transformer is securely plugged into a wall
receptacle which is NOT controlled by a switch which may be turned off at times. If the display screen
is blank, power is currently off. The system’s computer retains information in memory for two hours
during an outage and then redisplays the information when power is restored. Thus, you may not know
the power was off during that short period. If time of day is flashing, power was out for more than two
hours. Reset time. Check fuses, circuit breakers, plug-in transformer, etc. Since you may not know how
long the power was out, start a manual regeneration at this time to restore capacity to the system and
manually cycle once a day for 3 continuos days.
4. Bypass Valve…See bypass valve diagrams under “Vacation” to be sure that the system is not being
bypassed with untreated water. The valve handles should be in the NORMAL OPERATION position.
5. Unit is in Regeneration…If water is running to the drain the unit may be regenerating, in which case it
will deliver untreated water to the building. If regeneration is underway, water flow should cease within
2 hours and treated water will be available. The above condition indicates that the time of day is set
incorrectly. Reset time of day. If time of day is correct, then the time of regeneration may be set
incorrectly. Call dealer to reset this setting. If water does not stop flowing to the drain within 2 hours,
then there is an internal leak and a service technician must be called.
6. Exhausted Capacity…If none of the above system checks identify the problem, start a manual
regeneration. Call for service if the manual regeneration does not produce or maintain treated water.
