How a Duplex Water Softener Works

Hard water flows down through the resin in both tanks and the hardness minerals are trapped. The softener tracks how much water is treated and displays the amount of water each tank can still treat. For example, the left- hand tank can treat 1m3 of water, while the right-hand tank can treat 0.4m3 of water. When one tank has trapped as much hardness as it can, salt is used to flush the tank out while the other tank continues to supply softened water.

Product Usage Instructions

• Step 1: Installation
  Follow the installation guide provided in the user manual to set up your water softener. Ensure that the softener is placed in an appropriate location and connected to the water supply according to the instructions.

• Step 2: Setup
  Once the softener is installed, follow the setup instructions to configure the settings. This may include setting the water hardness level, adjusting the flow rate, and programming any additional features or preferences.

• Step 3: Operation
  After the installation and setup are complete, the water softener will automatically start treating the incoming water. The softener will track the amount of water treated and display the remaining capacity of each tank. When one tank reaches its capacity, the softener will initiate a regeneration cycle using salt to flush out the trapped minerals while the other tank continues to supply softened water.

Planning Your Installation.

• Please observe the regulations concerning the installation of your water softener. For guidance check out the water regulations advisory service web site (www.wras.co.uk) Check that you only have one rising main, that you have allowed space for access to the unit for possible future maintenance and salt replenishment. Check the water pressure; locate the rising main (stop cock) a drain facility and a power supply.
• Unless you are replacing an existing water softener, this installation will require you to carry out plumbing work and may require an electrical outlet to be fitted near the softener. You should only attempt this if you have the necessary skills.

Positioning the Softener.

Where possible the softener should be placed close to the rising main. Take care to allow hard water take off points for a drinking water facility and /or an outside tap. The distance between the drain and the Softener should be as short as possible. Ensure that both the drain and overflow will not freeze or reach a temperature above 40°C. If putting the Softener within a cupboard ensure that the base is adequately supported. If the Softener is being installed within your loft etc it is recommended to house the Softener within a tank capable of storing at least 100 Litres with an overflow fitted. The overflow on the tank should be below the Softener overflow and be a minimum of ¾” in size.

A single Check Valve

A suitable check valve should be fitted. This will usually be in the installation kit that can be ordered separately.

Check List

Before you start the installation make sure that you have all the necessary fittings. The purchase of one of our standard installation kits will normally ensure that you have everything that you need for a typical installation.

Water Pressure Test

It is important that a pressure test is carried out. High and low water pressure can result in either damage to or failure of the Softener. Although the Softener is tested to a pressure of 8 bar (120psi), we recommend the fitting of a pressure limiter should your pressure exceed 5 bar (70 psi). The minimum working pressure is 1.4 bar (20 psi)

Before starting the installation of the valves ensure that the stop cock is in the closed position.

Connecting the Softener

Once you have completed the installation of the valves set the valves as follows:

• Softener Inlet and Outlet valve CLOSED, Bypass valve OPEN
  You can now safely return the stop cock to the open position. Using the hoses provided (if installation kit ordered) connect the straight end of the hose having first inserted the washer provided to the softener inlet and outlet valves. Connect the angled end of the hose to the Softener. The Softener inlets and outlets and drain are marked on the softener.

• Close the BYPASS and slowly OPEN the inlet and outlet****

Waste Pipe Installation.

Run the waste hose to either an up stand or outside drain, a minimum air gap of 20mm must exist at the end of the drain line. Softened water will have no adverse effect on a septic tank. Should you need to extend the drain hose this can be for a maximum run of 8 meters with a minimum daytime pressure of 40 psi. Ensure that the drain hose is not kinked or obstructed in any way as this will lead to an overflow of the softener. The drain pipe can run uphill to a maximum of 1 Meter with a minimum water pressure of 40 psi.

Overflow Connection.

The overflow connection is the white ½” hose spigot on the rear or side of the cabinet. The overflow must be run downhill through an outside wall without kinks or restrictions. It is recommended the overflow hose be visible when it exits the outside wall.

Preparing the Softener to go into service.

Ensure turbine cable is clipped into outlet pipework (see picture previous page)

• Put approximately 5 litres of water into the brine tank.
• You may also at this point put a quantity of salt into the tank. Do not allow the salt level in the brine tank to exceed the height of the overflow. You should keep the salt level above the water level and check the salt level on a regular basis until a usage pattern has been established.

Softener Controller

• If the version of the softener you have bought comes with a remote controller insert the batteries. The controller allows for remote control over the softener. To link the remote controller, on the controller press “up” and “down” button for 3 seconds, then press “down” to find SETID. At this time, connect the power on the softener. Press the confirm button on the remote controller and wait to hear “Di” sound, it means the connection is successful.
• The display shows information on the remaining capacity of the left and right tanks, the current flow rate from the softener and the time.
• You can use the controller to begin a manual regeneration or to adjust the time and hardness settings.
• This is done in the same manner as on the softener. See programming and commissioning softener section.

Quick Start

Programming the Valve
When plugging in the softener initially it will display the valve model information then go to the main screen showing the Time, Right and left tank capacities and whether each unit is in service or regeneration.

Commissioning the Softener

Introduction.
With the softener fully plumbed and the valve programmed commissioning can start.

Regeneration.

• When the softener is fully functional the regenerations will happen as automatically.
• To initiate an immediate regeneration press the Manual button until the valve motor starts to turn.
• If during a regeneration cycle you need to skip through the cycle this can be done in the following way.
• To skip to the next stage quickly press the Manual button and this will take it to the next stage of the regeneration, this can be repeated to get to the end of the regeneration cycle.

Service.

• Water flows into the valve at the top, down through the resin and then up through the ‘riser’ tube in the middle of the vessel. As the water travels through the resin the ion exchange takes place. The controllers are set to automatically regenerate on capacity.
• The display on the control will show the following; In service and the remaining capacity.

Routine Maintenance.

• Check the salt level (this may need to be done more regularly dependent on consumption)
• The salt level should always be above the water level.
• Check there is no sign of damage or leaks.

Programming the Valve (in case of memory loss).

Should the programming have been lost in transit the following instructions in conjunction with the setting sheet will allow you to re set it. For time, date and hardness settings see the quick start section on page 4. The settings below should not be altered without good reason.
