Preface Thank you for choosing this Hankscraft Runxin water softening system for your water treatment needs. Please read this manual carefully before attempting to use the system for the first time, and ALWAYS adhere to all safety and operating instructions. Doing so will protect your warranty and help keep your system running and operating safely and effectively.

***Before installing, read through this manual thoroughly. Failure to use this product

within the described conditions may void the warranty***

All plumbing and electrical work should be performed by an accredited professional to ensure all local, municipal, state, and federal guidelines are met.

Do not use the control valve with water that is unsafe or of unknown quality. This system does not sanitize or disinfect.

Do not use the brine tube, injector body, or other connectors on the RevV valve as a handle to carry the system.

Ensure there is salt in the brine tank at all times when this valve is used for softening. The brine tank should contain clean water and pellet softening salt only, at least 99.5% pure. The use of small grain or solar salt is not recommended.

When there is moderate to high turbidity, a filter should be installed before the water softening system on the inlet side.

If the water pressure exceeds 120psi, a pressure reducing valve must be installed before the water inlet. If the water pressure exceeds 80 psi, installing a pressure reducing valve before the water inlet is highly recommended. If the water pressure is under 21psi, a booster pump must be installed before the water inlet.

Replacement parts for the RevV valve should only be purchased through Hankscraft resellers. Electrical components such as transformers are specific to the RevV valve from Hankscraft.

Regular interval monitoring of the water quality and work environment is recommended to insure proper operation of the valve and system.

1. Product Overview 1.1. Main Application & Applicability

1.2. Product Characteristics

Overview The advanced design incorporates a microcomputer control that analyzes real-world operating

conditions and performs regeneration automatically. This unique control valve features highly polished, patented ceramic discs. The design incorporates one fixed and one moving disc, which rotates through positions to align channels creating five different fluid pathways. These five pathways, or stages, are: Service, Backwash, Brine & Slow Rinse, Brine Refill, and Fast Rinse. Two Installation Options

Use side-mounted connector to change the valve from a top-mounted to side-mounted system.

Brine Refill Controlled By Electronic Ball Valve During service, electronic ball valve will trigger during the brine refill.

Manual Function Regeneration can be prompted by pressing at any time.

Extended Power Outage If there is a power outage of more than 72 hours (3 days), the time of day indicator “” will

flash to remind the end user to reset the current time of day. The other set parameters do not need to be reset. The system will resume working after power is restored. LED Dynamic Screen Display Moving (green) display bar indicates the control valve is in service, otherwise, it is in the

regeneration cycle. Buttons Lock If the display board is not in use for more than 1 minute the buttons will lock. A light indicating

this will appear. Before operating again press and hold the “ ” and “ ” buttons for 5 seconds to unlock. This function can deter unintended operation.

Program Model Selection Press and hold “ ” and “ ” buttons for 2 seconds, all the icons will light up, indicating access

to the model setting interface. Press “ ” or “ ” to navigate to specific model, then press to save the setting chosen, after reconnecting the power, the model will be visible on the display board. Interlock Function The interlock function is designed to have only one valve in regeneration, at a time, while

multiple other valves are in service in a parallel valve system. In multi-step treatment systems such as RO pre-treatment, when several valves are in series, there is only one valve in regeneration or washing to ensure product water at all times.(Application refer to Figure 3-9)

All Parameters Can Be Modified Depending on the water quality and usage, the parameters in the system can be adjusted.

Signal Output There is a signal output connector on the main control board. This connector is designed to

control external devices (Refer to Figure from Figure3-1 to Figure 3-8).

b-01 and b-02 output modes: b-01: a signal that is sent through the entire duration of cycles during regeneration. In this mode, the signal can be sent once per cycle; b-02 Mode: the signal is sent at the end of one cycle and at the beginning of another. In this mode, the signal is sent five times per one complete cycle.

Remote Handling Connector This valve has a remote handling connector. An external device can determine when water

quality is below desirable levels. When this occurs, the valve has the capability to respond to a remote signal and regenerate. (Application refer to Figure3-11)

Pressure Relief Output The valve will cut off feed water to the drain line when it switches in regeneration cycles (Same

as signal output b-02). Some water treatment system, e.g. Deep Well, one booster pump is installed on the inlet to increase the system feed water pressure; this cut-off will prevent pressure on inlet from rising too quickly, potentially preventing damage to the valve. Pressure Relief Output can be used to avoid this problem. (For application refer to Figure3-10) Meter type(s) that can be selected (RevV 20) Model Name Instruction

A-01 Meter Delayed Regeneration happens when the capacity reaches zero and the preset time of regeneration is reached.

A-02 Meter Immediate Regeneration happens when the capacity reaches zero.

A-03 Intelligent Meter Delayed

Meter Delayed Regeneration type, but by setting Resin Volume, Feed Water Hardness, Regeneration Factor, the controller will calculate the System Capacity. Regeneration mode is the same as A-01.

A-04 Intelligent Meter Immediate

Meter Immediately Regeneration Type, but by setting Resin Volume, Feed Water Hardness, Regeneration Factor, the controller will calculate the System Capacity.

Maximum Interval Regeneration Days System will automatically regenerate even if the water capacity was not reached in the time

allotted. (Set on site)

B. Device Location ① The filter or softener should be located close to the drain. ② Ensure that the unit is installed with enough space for operation and maintenance. ③ Brine tank needs to be close to the softener. ④ The unit should be kept away from heat, and should not be exposed to the elements. Sunshine or rain will cause the system damage. ⑤ Avoid introducing the system to Acid/Alkaline feed water or Magnetism/vibration, as this may cause the system to malfunction. ⑥ Do not install the filter, softener, or drain pipeline in areas where temperature may drop below 5℃, or rise above 50℃. (41F~122F) ⑦ Install the system in a location where the risk of loss for the customer is minimal, in case of water leaking. C. Pipeline installation (RevV 20-A top-mounted as an example: Figure 1-3)

① Install Control Valve a. As the Figure 1-1 shows, select a riser pipe that is 50mm OD, glue the riser pipe to the bottom strainer and put it into the mineral tank, cut the excessive tube off that is coming out the top opening of the pressure tank. Plug the riser tube to prevent unwanted minerals. b. Fill the mineral tank with resin, height according to the design code. c. Attach the top distributor basket to the valve. d. Insert and fasten the riser tube into the control valve. Note: ●The length of riser tube should not be higher than 2mm nor lower than 5mm from the tank’s top opening height, and its top end should be rounded to avoid damage of the O-ring inside the valve. ●Avoid dropping the O-ring from inside the control valve while rotating it on the tank.

② Install Flow Meter

As below figure shows, put the sealing ring into the nut of the flow meter, and attach it to the water outlet; insert sensor (probe wire) into the flow meter.


9

③ Pipeline Connection a. As Figure1-3 shows, installation of a pressure gauge on water inlet. b. Install sampling valves to inlet, outlet, and pipeline A.B.C.D. c. Inlet pipeline should be parallel to outlet pipeline. Fasten the inlet and outlet pipeline(s) with a fixed holders.

Note: ● If making a soldered copper installation, do all sweat soldering before connecting pipes to the valve. Torch heat will damage plastic parts. ●When turning threaded pipe fittings onto plastic fitting, be sure not to cross thread. ●If the valve is a time clock type, skip step ②. ④ Install Drain Pipeline

Glue the drain outlet with UPVC (DN40). Put drain outlet pipe to sewer as shown in the Figure 1-4.

Note: ● Control valve should be higher than the drain outlet, and should be separated from the drain hose by at least 2 inches. ● Be sure not to connect the drain line directly to the sewer to avoid wastewater contamination.

⑤ Connect Brine Tube

a. As Figure1-5 shows, use 3/4” brine tube hose connector over the end of the brine tube. b. Insert the tube bushing into the end of the brine tube. c. Tighten the brine draw hose connector to the brine line connector. d. Connect the other end of the brine line hose to the brine tank.

Note: Keep brine line short and smooth. Line should not be bent or plugged.

C. Working Process: Service→ Backwash→ Brine & Slow Rinse→ Brine Refill→ Fast Rinse→ Service. D. Usage

After installation is completed, parameters are set, and a trial run is completed, the valve is ready to be put into use. In order to ensure the quality of outlet water, the user should complete the steps below:

① Ensure that there is solid salt at all times in the brine tank when the valve is used for softening. The brine tank should use softening salts only, 99.5% pure.

② Test the product water and raw water hardness on a regular basis. When the outlet water hardness is at an undesired level, press the button; the valve will temporary regenerate (It will not affect the original set operation cycle.)

③ When the feed water hardness changes, you can adjust the water treatment capacity as follows:

Press and hold both and for 5 seconds to lift the lock status. Press , and the light turns on, then press , the display shows the control mode. If it shows A-01 or A-02, press

two times, and the display will show the given water treatment capacity (If the control mode shows A-03 or A-04, then press three times, the display will show the feed water hardness); Press again, on display will flash. Press or to change the capacity value (Or water hardness). Press a confirmation beep will sound finishing the adjustment. Press to exit and return to service status.

To calculate the water treatment capacity, refer to the manufacturer’s specifications. Selecting A-03 or A-04 intelligent control mode, the control will automatically calculate the water treatment capacity by setting resin volume, feed water hardness, and regeneration factors.


14

④ For A-01 or A-03 control mode (Delayed regeneration type), ensure the time is set correctly. If the time is not correct, you can adjust as follow: After lifting the lock status, press , the buttons and light will turn on. Then press , the buttons and hour value will flash. Press or to change the hour value; Press again, and minute value will flash. Press or to change the minute value; Press a confirmation beep will sound finishing the adjustment. Press to exit and return to service status.

The regeneration parameters have been set when the control valve left the factory to default settings or set up on initial installation. Generally, there is no need for it to be reset.

3.2. The Function and Connection of PC Board

Open the front cover of the control valve, you will see the main control board and connection port as seen below:

Functions on PC board:

Function Application Explanation

Signal output connector b-01

Outlet solenoid valve

If the system requires no hard water to flow from outlet or if controlling the liquid level in water tank.

Inlet pump Increase pressure for regeneration or washing. Use the liquid level controller to control inlet pump, ensuring there is water in tank.

Signal output connector b-02

Inlet solenoid valve or inlet pump

Used when inlet pressure is high, closes water inlet when valve is rotating to protect motor.

Pressure relief connector

Control the inlet bypass to release pressure

When valve is rotating, pressure relief connector opens to prevent pressure from increasing rapidly.

Interlock connector

To ensure only one control valve is in regeneration at a time in a system.

Used in RO Pre-treatment, water is supplied simultaneously but regenerate in turn. Also, used in second grade ion exchange equipment, etc.

Remote handling connector

Signal triggers the control to rotate to the next cycle.

It is used for on-line inspection systems, PC connections, and automatic or remote controlling valve.


16

A. Signal Output Connector 1） Control Solenoid Valve (Set b-01) ① Solenoid valve on the outlet controls the water level in brine tank. Instruction: If the system requires there to be no hard water flow from the outlet in regeneration cycle (Mainly for no hard water flow out when valve is switching or valve is in backwash or brine drawing positions), a solenoid valve could be installed on outlet, for wiring refer to Figure 3-1.

Function: When valve is in service status, if soft water tank is short of water, solenoid valve is open to

supply soft water, but if water tank has enough water, solenoid valve is closed, and no soft water is supplied. When the valve is in backwash status, there is no signal output. Therefore, the solenoid valve

is closed, and no water flows into soft water tank. ② Solenoid valve on inlet (Set b-02) Instruction: When inlet pressure exceeds (0.6MPa~87psi), install a solenoid valve on inlet. Control mode is b-02. Pressure is relieved when valve is switching to prevent damage, for wiring refer to Figure 3-2. As Figure 3-3 shows, it can also use the pressure relief port to work.

Instruction:

When inlet pressure is high, install a solenoid valve on inlet to ensure the valve can switch properly. When valve is in position for Service, Backwash, Brine & Slow Rinse, Brine Refill and Fast Rinse, solenoid valve is open. When valve is switching between cycles, the solenoid valve


17

is closed, ensuring no water can flow to the valve protecting it from damage during transition. This can prevent water bleed through or water hammering.

Use interlock cables to daisy chain valves in parallel, or series, in the same system which is suited for RO pretreatment system or second grade Na+ system. For wiring refer to Figure 3-4:

2） Liquid Level Controller Controls Inlet Pump (Two-phase motor) ( Set b-01) Instruction: For a system using well or middle-tank supplying water, liquid level controller and valve, together, control pump opening or closing. For wiring refer to Figure 3-5:

Function: When the valve is in service, if the water tank is short of water, it starts the pump, but if the

tank has enough water, the switch of liquid level controller is closed, so the pump will not be in operation. When valve is in regeneration, inlet always has water no matter the condition(s) in the water

tank. Valve does not pass water through the outlet in regeneration cycle, ensuring no water drains into the brine tank.

3） Liquid Level Switch in Water Tank Controls Inlet pump (Three-phase) (Set b-01)


18

4） Control Inlet Booster Pump (Set b-01 or b-02) Instruction:

If inlet water pressure is less than (0.2MPa~29psi), which makes drawing difficult, a booster pump is suggested to be installed on the inlet. Control mode b-01. When the system is in regeneration, booster pump is open, for wiring refer to Figure 3-7. If the booster pump current is higher than 5A, system needs to have a contactor installed. For wiring refer to Figure 3-8 below.

B. Interlock Instruction:

In a parallel water treatment system, to ensure only one valve in regeneration or washing cycle and (n-1) valves in service, that is, that the function of supplying water simultaneously and regenerating individually, for wiring refer to Figure 3-9.

Note: Use Interlock Cable to connect CN8 to CN7 on next valve in the loop.

In a system with several valves, if the interlock cable is disconnected, the system will be divided into two individual systems.


19

C. Pressure Relief Output

Valve will cut off feed water to the drain line when there is a switch in regeneration cycles. In some water treatment system, e.g. Deep Well, one booster pump was installed on the inlet to increase the system water feed pressure. This cut-off will prevent pressure on the inlet from rising too fast, protecting the valve. Pressure Relief Output can be used to avoid this problem. For wiring refer to Figure 3-10.

D. Remote Handling Connector

Online TDS meter can monitor treated water rather than a flow meter, or PLC controlling

the regeneration time. When the controller receives a contact closure from above instruments, regeneration begins. For wiring refers to Figure 3-11:

E. Interlock System

For 2 or more valves that are interlocked, connected in one system, and when all valves are in service but regenerate individually. For wiring refer to Figure 3-12.


20

F. Series System

This is a 2 or more valve system, all in service, with one flow meter for the entire system. For

the time type valve, the regeneration time should be set and adjusted to the Max; for the volume type valve, connect its signal output connector with the remote handle connector of the time-type valve. This provides the function of supplying water simultaneously and regenerating in order. For wiring refer to Figure 3-13:

3.4. Parameter Settlement ① Service Time T1 Water treatment capacity:

Q=VR×K÷YD (m3) Hardness of inlet water (mmol/L)

Exchange factor (mmol/L) 400~1000. Down-flow regeneration, take 400~750. Up-flow regeneration, take 450~1000. If the inlet water hardness is higher, the factor is smaller.

Resin volume (m3)


22

By hours: T1=Q÷Qh (Hour)

Water treatment capacity per hour (m3/h) Water treatment capacity (m3)

By days: T1=Q÷Qd (Day) Water treatment capacity per day (m3/d)

Water treatment capacity (m3)

② Backwash Time T2 It is subject to the turbidity of inlet water. Generally, It is suggested to be set to 10~15

minutes. The higher the turbidity is, the longer backwash time can be set. However, if the turbidity is more than 5 FTU, it would be better to install a filter before the exchanger.

③ Brine & Slow Rinse Time T3

T3= (40~50) × HR (min.) Generally, T3=45HR (min.)

In this formula, HR——the height of resin in exchange tank (m.) ④ Brine Refill Time T4

Down-flow regeneration：T4＝0.45×VR÷Brine refill speed (min.) Up-flow regeneration：T4＝0.34×VR÷Brine refill speed (min.)

In this formula, VR—— Resin volume (m3) The Brine refill speed is related to inlet water pressure. It is suggested to increase by 1~2

minutes of calculated brine refilling time to make sure there is enough water in tank. (The condition is that there is a level controller installed in the brine tank).

⑤ Fast Rinse Time T5

T5=12×HR (min.) Generally, the water for fast rinse is 3~6 times of resin volume. It is suggested to be set

10~16 minutes, but subject to the outlet water reaching the requirement.

⑥ Exchange Factor Exchange factor =E / (k×1000) In this formula, E——Resin working exchange capability (mmol/m3), it is related to the

quality of resin. Down-flow regeneration, take 800~900. Up-flow regeneration, take 900~1200. K——Security factor, always take 1.2~2. It is related to the hardness of inlet water: the higher the hardness is, the bigger the K is. ⑦ Regeneration Time The whole cycle for regeneration is about two hours. Please try to set up the regeneration time

when you don’t need water according to the actual situation. The calculation of parameters for each step is only for reference, the actual time will be

determined/adjusted by the water softener supplier. This calculation procedure of softener is only for industrial application; it is not suitable for small softeners in residential applications.

Fill the brine tank with the planned amount of water and adjust the air check valve. Then add solid salt to the tank dissolving the salt as much as possible.

C. Turn on power. Press and go in the Backwash position; when light is on (For floating bed, switch valve to Fast Rinse), slowly open the inlet valve B to 1/4 position, making the water flow into the resin tank; you should hear the sound of air-out from the drain pipeline. After all of the air is out of the pipeline, open inlet valve B completely to clean the foreign material out of the resin tank until the outlet water is clean. It will take 8~10 minutes to finish the whole process depending on media. D. Press , advancing the position from Backwash to Brine & Slow Rinse; when light is on it indicates the valve is entering Brine & Slow Rinse. The air check valve closes when control valve finishes drawing brine; slow rinse starts. About 60~65 minute process.

E. Press to get to Fast rinse position. Light turns on. It takes about 10~15 minutes. Remove some outlet water for testing: if the water hardness reaches the desired requirement, and the chlorides in the water are almost the same level compared with the inlet water, then proceed to the next step. F. Press to Brine refill position. When the light is on it indicates the brine tank is


27

being refilled with water to the required level. It takes about 5~6 minutes, then add solid salt to the brine tank.

G. Press , this forces the control valve to advance to “In Service” status; light turns on and valve will start running. Note: When the control valve enters into the regeneration status, all programs will be finished automatically according to the setting time; if you want one of the steps to terminate early, press

. If the water inflow is too fast, the media in tank will be damaged. When water inflow is too slow, there is a sound of air emptying from the drain pipeline. After changing resin, empty air that is in the resin according to the above Step C.

In the process of trial running, ensure there are no leakages in any cycle. The time for Backwash, Brine & Slow Rinse, Brine Refill and Fast Rinse position can be set and carried out according to the calculation in the formula or suggestions from the control valve suppliers.
