INTERVENTIONS PLUMBING.

Thank you for your trust in BWT by purchasing this softener.

IMPORTANT: before any hydraulic or electrical connection, commissioning, use or mainte- nance, please read carefully this manual. The non-compliance with its instructions may void warranty.

REQUIREMENTS FOR USE USE This device is not designed for treating non- drinking water. Therefore, if it delivers drinking water, it must exclusively be connected to a water supply already in compliance with the requirements set by the applicable standards.

UNPACKING Check that the device and its packing have not been damaged during transportation. Do not use the device in case of any visible damage, and contact the vendor.

LOCATION The device location shall be:

+ flat, clean, dry, properly ventilated and not accessible to unauthorized persons.

+ protected from bad weather, heat sources and chemical product vapors.

INTERVENTIONS The owner of the appliance holds the responsi- bility for making sure that any installation, care or maintenance work is carried out by a duly authorized person, with proper skills and tools, and fully aware of this manual content.

The work shall be performed according to the state of art and the standards applicable in the room where the device is installed, especially regarding plumbing, electricity and handling of chemical products (see here-below).

PLUMBING It is especially important to fit efficient water- hammer arresters if the softener input and/ or output are connected to devices likely to generate water-hammer effects (for example, solenoid valves).

ELECTRICAL CONNECTION Avoid any intermediate connecting device {extension cord, power strip) between the device

and the wall outlet. Check the circuit compliance towards all appli- cable electricity standards, especially regarding electrical grounding as well as electrical safety. Do not try to connect the device if its power supply wire is damaged. Please contact the vendor in order to get a new complete set of wire + transformer.

Before plugging the device to the wall outlet, cut off the power on this outlet by using the concerned circuit breaker or by removing the concerned fuse.

Ifthe device is installed close to any equipment with high electromagnetic parasites emissions {such as a high power transformer) it is neces- sary to reinforce its standard protection towards usual parasites by the proper parasite arrester system and a shielded wire.

Do not open the electrical controller of the device without the proper qualification. Elec- trocution hazard.

CHEMICAL PRODUCTS HANDLING Chemicals may be necessary for certain servicing operations. The user shall be fully aware of any hazard involved in those and use the proper personal or collective protective equipment accordingly.

It is under the installer’s responsibility to make sure that the installation does not generate any water hammer which could damage the proper work of the softener.

Our softeners are equipped with a check valve on the water inlet connection flange. The check valve may exit the flange under extreme operating and mounting conditions. To avoid this phenomenon, it is mandatory to connect the softener with flexible hoses (according to

diagram here below). Hose check valve

Progressively open the bypass tap (or the upstream cutting valve of the installation).

Purge the remaining air by using the purging screw upon the filter (unscrew it, then screw it back once the air is purged). Plug the softener to the electricity outlet.

SETTING Atits first start-up, the device displays after a few seconds the message SERV, first step of the setting, which uses 5 keys:

Key Name Function Activates the menu with a long press (5 seconds)

> Right + Move from left to right digits (example: hours to minutes) + Enter into a menu + Setting validation

+ A long press (5 seconds) triggers a manual regeneration. During this process, a brief press forces the trigger of the next step.

The following steps are necessary and sufficient to set the softener. You just need to knowthe hardness ofthe raw water (concentration in lime scale), measured before or known from the public water distribution network. First press 3 seconds on the key M, until the message LANG appears on the display.

OPERATION SALT REFILL The device uses regenerating salt, dedicated to softening. The salt tank bottom shall always be covered by solid salt over its whole surface. Please refer to the Scope of Delivey sheet in order to know the salt storage capacity of vour softener, and to the chapter TECHNICAL FEATURES to know its salt consumption per regeneration.

Concerning the softeners with salt level follow- up by smartphone app:

After every salt refill, enter the salt level so that the app may follow it up.

+ Check the salt level once the refill is done, on the scale inside the salt tank

+ Press 5 seconds the > key to see LEVEL on the display

+ Select the salt level with Ÿ and # keys

+ Confirm with OK E AUTOMATIC DISPLAYED MESSAGES The displays shows: © an upper information line © a lower information line © a bargraph with 10 segments, showing the remaining autonomy of the softener before the next regeneration, by steps of 10%.

TROUBLE SHOOTING Root causes

The displays shows alternative CHECK

and SALT There is not enough salt left in the tank OR The device detects a regeneration flaw.

Refill the tank with salt.

If it does not look to need refill, contact the tech- nical service.

The time on the display is not correct

The seasonal time change has not been done OR

À power cut occurred and the data recovery did not work (battery KO).

Reset the timing (see chapter SETTING).

Ifthe problem comes up again, contactthe technical service.

The power is off oR There is an electric or electronic failure.

Checkthe power outlet where the device is plugged.

If the power outlet works, contact the technical service.

Water flow through the evacuation tube (8)

The device is regenerating (which means that there is no problem)

OR The internal components meet a failure.

Check that the device displays REGE 1, REGE 2 or REGE 3.

If not, contact the technical service.

Water overflow from the salt tank (10)

The brining chain does not properly close or leaks.

Check the connection between the bring tube (9) and the brine valve (5). Ifthe problem remains, contact the technical service.

The water delivered by the device does no longer look softened (lime scale coming back, etc.)

Many possible root causes. Step through all the checks on next column

Measure the residual hardness once first, then after each of the following steps until the result is OK. Check that the bypass is open to direct the water to the softener. If not, change its position.

Check that there is still salt in the tank. Ifnot, refil it. Check if the type of salt is well selected in the programming.

Check that the filter element is not clogged. If so replace it.

Go again through the blending procedure (see chapter COMMISSIONING)

Ifthe problem remains, contact the technical service.
