General
• Observe all warnings that appear in this manual.
• Keep the unit in the upright position. Do not turn on side, upside down, or drop. Turning the
tank upside down or laying the tank on its side will cause media to enter the valve.
• Operating ambient temperature is between 35.6°F (2°C) and 120°F (49°C).
• Operating water temperature is between 39.2°F (4°C) and 100°F (38°C).
• Working water pressure range is 0.14 to 0.35 MPa (20 – 50 PSI).
• Use only salts designed for water softening. Do not use ice melting, block, or rock salts.
• This system is not intended to be used for treating water that is microbiologically unsafe or
of unknown quality without adequate disinfection before or after the system.
• Do not allow this water conditioning system to freeze. Damage from freezing will void this
water conditioning system’s warranty.
• The materials used will fade or discolor over time in direct sunlight. The integrity of the
materials will degrade to cause system failures.
• The carbon filter removes organic pollutants (such as oxygen demand and
trichloromethane), odor (chlorine smell, etc.) and particulate matters. It does not remove
salt or viruses. Hence the treated water is not recommended for direct drinking.
• Do not leave the filter system unused for an extended period. Please turn off the water
supply valve if the filter system is not used for an extended period. After an extended
period of non-usage, please rinse the filter system thoroughly before use.

4. INSTALLATION INSTRUCTIONS
________________________________________________________________________________________________________________________________________
4.1 Precautions
The following conditions are required for the installation of the carbon filter system:
• Installation and working space : Not less than 350x 350 mm, 170 cm high
• Distance between centers of inlet and outlet: 10.2cm
• Distance between power source and carbon filter: No greater than 2m.
• Level platform or floor.
• Constant electrical supply to operate the controller.
• Total minimum pipe run to water heater of ten feet (three meters) to prevent backup of hot
water into system.
• Local drain or tub for discharge as close as possible.
• Water line connections with shutoff or bypass valves.
• Must meet any local and state codes for site of installation.
• Valve is designed for minor plumbing misalignments. Do not support weight of system on
the plumbing.
• Be sure all soldered pipes are fully cooled before attaching plastic valve to the plumbing.
• Room to access equipment for maintenance and adding media to tank.
• After some maintenance work on pipe network, the initial effluent from the faucet often
contains a lot of rust and pollutants. Therefore, after each occasion of water supply
stoppage, please open the bypass valve or bypass pipe to drain out dirty water; or install a
filter before this filter system to ensure that only clean water will enter the water filtration
system. Generally, influent turbidity should be controlled at less than 5NTU.
• Generally, the carbon filter is installed after the water meter at the entrance of indoor tap
water; the water meter can then be used as a gauge for determining the amount of water
treated.
• Hot water can cause damage to the internal processing system of the carbon filter. Users
who connect hot water boiler or instant water heater after the carbon filter must install a
check valve between the carbon filter and their water heating system, and ensure that their
water heating system is equipped with temperature and pressure control safety devices.
• When installing carbon filter in newly renovated premises where water has not been
used before, first open the water faucet to discharge the water for at least 10 minutes to
completely flush away any construction debris, corrosion rust and dirt. This will prevent
dirt from entering the connected carbon filter during installation and cause damages to
internal filter materials.
• A manual valve should be installed just before the inlet and outlet respectively. A bypass
valve or bypass pipe should be installed between the inlet and outlet to facilitate normal
water usage during maintenance of the carbon filter, or to enable direct usage of non-
treated water when needed.
• It is recommended that a pre-filter be installed before the inlet to prevent contaminated
water from entering the carbon filter system, thus affecting its operation.
• As much as possible, reduce the length and curvature of the drain line. Always allow an
air gap between the drain line and the wastewater to prevent the possibility of wastewater
being back-siphoned into the carbon filter. No valve of any type should be installed along
the drain line.

_________________________________________________________________________________________________________________________________________
• All pipes must have their own support brackets, the weight or stress exerted by such pipes
must not be carried by the controllers of the carbon filter.
• Inlet or outlet pipes can be hard piping or flexible hose depending of the user’s specific
need and situation.
• The system comes with a power transformer; the user needs to provide a stable 220V/50Hz
AC power supply. The automatic control feature of this product requires a continuous and
stable power supply. In the event of power outage when the system is in use, the system’s
original setting will be maintained by data protection feature of the built-in electronic
controller, and the system can continue to operate for 8 hours. Information related to volume
processed will also be maintained for 8 hours. If power outage exceeds 8 hours, you will need
to reset the system time to enable it to operate in accordance with its original setting.
• It is recommended that the user operate the system below its rated system flowrate.
Exceeding the rated system flowrate will result in overloading. In no circumstances should
the system be operating beyond 1.5 times the rated system flowrate.
• If the carbon filter will not be used and is not connected to the power source for an
extended period of time (for more than one month), one should try to reconnect the power
and water supply every week (the shorter the better) to perform a backwash for several
hours. This is to ensure optimal performance of the filtration system when restarted.
• In the event of occasional water stoppage or power outage, one should turn off both the
inlet and outlet valves and disconnect the power supply.
• Under normal circumstances, it is recommended that KDF, granular activated carbon and
gravel be replaced when the rated system capacity for treatment of chlorinated city water
is reached. Please contact your local Pentair authorized distributor for replacement of
KDF, granular activated carbon and gravel.
Part Name Replacement Period (Recommended)
Granular Activated Carbon 6 months
Gravel 5 years
KDF 2 years
• After prolonged periods of non-use, it is recommended that the carbon filter system be
flushed for 5 minutes before it is used.
• It is recommended that the equipment be installed indoors. When the water conditioning
system must be installed outdoors, below conditions must be considered:
• Moisture —The system is not designed to withstand extreme humidity or water spray
from below. Examples are: constant heavy mist, near corrosive environment, upwards
spray from sprinkler.
• Direct Sunlight — The materials used will fade or discolor over time in direct sunlight.
The integrity of the materials will not degrade to cause system failures.
• Temperature — Extreme hot or cold temperatures may cause damage to the valve or
controller. Freezing temperatures will freeze the water in the valve. This will cause
physical damage to the internal parts as well as the plumbing.
• Keep the media tank in the upright position. Do not turn upside down or drop. Turning the
tank upside down or laying the tank on its side can cause media to enter the valve.

Equipment Installation
If you are also installing a water softener, the softener should be installed downstream of
this system.
Grounding the Plumbing
It is important that the plumbing system be electrically grounded. When a water treatment
system is installed a nonmetallic bypass valve may interrupt the grounding. To maintain
continuity, a grounding strap can be purchased at a hardware store. When it is installed the
strap will connect the plumbing into the system to the plumbing leaving the system.
Water Line and Bypass Connection
Once you have selected your location check the direction of the water flow in the main pipe.
A bypass valve system should be installed on all water conditioning systems. The bypass
valve system isolates the filter from the water supply and provides untreated water to service
during routine maintenance and servicing procedures.
Normal Operation
• Valves 1 and 3 open
• Valve 2 closed
Bypassed Position
• Valve 2 open
• Valves 1 and 3 closed
Connect the connector kit to the water supply system: Wrap the ends of the connector kit with
Teflon tape; attached the connector kit to the incoming pipe; the carbon filter system is then
connected to the other end of connector kit; the connection is secured with the supplied U-clip.

_________________________________________________________________________________________________________________________________________
Precaution before connecting the carbon filter system to the connector kit:
• Check to ensure that all O-rings are in perfect condition.
• Lubricate the O-rings and contact surfaces with 100% silicone grease.
When removing the securing clip:
• Turn off the water supply and relieve the internal pressure on the valve.
• Push the connector kit towards the control valve to help loosen the sealing ring which may
be seated tightly.
• Place a screwdriver under the top end of the U-clip to help lift and remove the clip.
Installation of drain pipe
Drain pipe connection and installation instruction are as shown in the figure below:
• Wrap the threaded end of the flow controller with Teflon tape.
• Tighten the two components of drain connector kit by hand.
• Insert the drain connector kit onto the drain opening of the carbon filter.
• Insert the drain connector clip to secure the connection.
• Cut a suitable length of ½” flexible hose and connect it to the drain secure it with a cable tie.
• Secure the discharge end of the drain line to prevent it from moving.
NOTE: Waste connections or drain outlet shall be designed and constructed to provide for
connection to the sanitary waste system through an air gap of two pipe diameters or one
inch (22 mm), whichever is larger.
WARNING: Never insert drain line directly into a drain, sewer line, or trap (Figure above
Drain Line Connection). Always allow an air gap between the drain line and the wastewater
to prevent the possibility of sewage being back-siphoned into the filter.

Programming is completed.
If no button is pressed within 5 seconds, the controller will commence normal operation.
In normal operation (operating mode), the display will show the current time and a flashing
colon sign; the display will change alternately to show the amount of water filtered.
Start up & Commissioning
Upon completion of the above initial power up steps, the carbon filter needs to be put into
operation. Please follow the following procedures strictly to perform commissioning. (This
process is to be performed by the Pentair authorized distributor):
• Set the “Time of Day”, “Backwash Duration” and “Cleaning Cycle Interval” in accordance
with actual requirements. The control panel will return to operating mode with alternating
display of current time and amount of water filtered. Confirm that the bypass valve is
turned off and other external devices (connectors, valves, faucets) are connected securely
and are in proper operating condition. This should avoid any inconvenience during use.
SYSTEM STARTUP
The system will now need to be placed into operation. Please review MANUALLY INITIATING
A CLEANING CYCLE before attempting startup.
1. With the supply water for the system still turned off, position the bypass valve to the “not
in bypass” (normal operation) position.
2. Press and hold the “Backflush” button on the controller for three seconds. This will
initiate a manual cleaning cycle, and cycle the valve to the backwash position.
3. Filling the media tank with water:
A. With the system in backwash, open the water supply valve very slowly to approximately
the 1/4 open position. Water will begin to enter the media tank. Air will begin to be
purged to drain as the media tank fills with water.
WARNING: If opened too rapidly or too far, media may be lost out of the tank into the valve
or the plumbing. In the 1/4 open position, you should hear air slowly escaping from the
valve drain line.
B. When all of the air has been purged from the media tank (water begins to flow steadily
from the drain line), open the main supply valve all of the way. This will purge any
remaining air from the tank.
C. Allow water to run to drain until the water runs clear from the drain line. This purges
any debris from the media bed.
D. Turn off the water supply and let the system stand for about five minutes to allow any
trapped air to escape from the media tank. Turn on the water supply after five minutes.
Check for leaks.
The system is now fully operational.
