Safety instructions

  • The water treatment device can only be supplied with 12 V and 1500 mA. Observe all safety precautions in connection with the operation of electrical appliances during operation and maintenance.
  • If the mains cable of the water treatment device is damaged, it must be repaired by a qualified electrician.
  • The water treatment device is only suitable for filtering pre-treated tap water. It cannot be used to filter water with an unknown level of contamination or an unknown proportion of harmful organisms.
  • The water treatment liquid cannot be drunk directly. Do not drink it directly.
  • Do not block the overflow pipe and the drain pipe of the water treatment device.
  • Do not place any objects on the water treatment device.
  • Do not immerse the water treatment device in water.
  • Do not use the water treatment device outdoors or in direct sunlight.
  • The temperature of the water entering the treatment device must not exceed 38℃.
  • After the water treatment device has been shut off for more than a week, the water must be drained during 5 min before water coming from the device can be used for food purposes.
  • The power supply must not be interrupted while the water treatment device is in use in order to avoid timing errors, which would affect the originally set backwash start time.
  • As hot water can severely damage the internal treatment system, it should be ensured that there is a connecting pipe of at least 3 m in length between the outlet of the treatment device and the inlet of the hot water boiler. If the 3-m connection line cannot be assured, it is recommended to install a non-return valve between the water treatment device and the hot water boiler.
  • The permissible ambient temperature of the system is 5–40℃. If in doubt, take suitable frost protection measures so that the resin is not affected.

Functions and features

Automatic operation
The built-in time control has a 24-hour time control with which the running days and the backwash time can be set (the factory-set time is 2 a.m.).
Programme cycle functions

  • Operation: After the raw water has flowed through the water purifier at a certain pressure and flow rate, the impurities and colloids suspended in the water are captured; at the same time, the coconut shell activated carbon filters chlorine, organic  substances, turbidity, odours, etc. out of the water.
  • Backwashing: Backwashing with tap water from bottom to top through the water at the bottom of the machine, which causes the filter material to move and collide, serves to remove colloids from the surface of the activated carbon, and prevents subsequent contamination by bacteria settling on the carbon. The absorption capacity of the activated carbon is restored and the carbon is loosened. This does not affect the water pressure.
  • Fast rinse: The filter material is quickly rinsed through, the activated carbon layer is compressed, and the filter material regains its best filter properties.

Installation and maintenance

Installation notes
To avoid installation errors, please read the following instructions carefully.

  • As the control components are controlled by electronic circuits, a three-day power failure (72 hours) or an intermittent power supply may cause the time shown on the control valve display panel to result in an incorrect backwashing time for the water treatment device (check the time shown on the control valve panel and the actual time after continuous operation of approximately 3 months). After restoring the power supply, check whether the time displayed on the control panel is correct. If this is not the case, refer to the instructions to find out how to set the water treatment device clock.
  • If the water pressure of the water treatment device is lower than the specified operating pressure, install a booster pump, which should be installed at the front of the water inlet of the water treatment device. At the same time, the outlet pressure of the booster pump must not exceed 4.5 bar, otherwise a pressure-reducing valve must be installed between the booster pump and the water treatment device. WilTec GmbH is not responsible for detrimental effects and damage caused by an excessively high outlet pressure of the booster pump on the water treatment device.
  • If the main water supply is interrupted, the main valve of the supply line should be closed immediately or the bypass valve of the water treatment device should be switched to the bypass state to prevent the water treatment device from being damaged by the negative pressure in the pipework caused by the municipal water supply.
  • When the main water supply is restored, a large number of pollutants in the water pipe contaminate the treatment device. Therefore, first switch the bypass valve of the treatment device to the bypass station, open the tap in the house, and drain the water from the dirty water supply station.
  • The water treatment device must not be tilted or laid on its side during transport, installation or use.
  • The floor on which the water treatment device is installed should be level and have a loadbearing capacity of more than 300 kg ⁄m. In addition, an AC power supply, a water inlet and outlet interface, a waste-water pipe, and a floor drain should be available.
  • Installation area:
    • CF-M1-C: 380 × 440 × 595 mm (L×W×H)
    • CF-M1: 380 × 440 × 640 mm (L×W×H)
    • CF-M2: 380 × 440 × 1140 mm (L×W×H)
  • Do not install the treatment device near acidic and alkaline substances or near gases to avoid corrosion on the treatment device.
  • The water treatment device must be installed indoors. Measures must be taken to insulate the housing and pipework, in particular to protect against frost and solar radiation and for sealing.
  • It is forbidden to install the treatment device on a water pipe with a water pressure of more than 4.5 bar. If the water inlet pressure exceeds 4.5 bar, a pressure-reducing valve must be installed (to be purchased separately), otherwise the company accepts no responsibility for consequences such as impairment or damage to the water treatment device due to excessive water inlet pressure and any resulting damage.
  • The water treatment device should be installed and used in a room with a floor drain and smooth drainage. If the drain pipe or floor drain is blocked and the drain pump cannot drain normally due to a power failure or other malfunction, please close the building’s main water inlet valve immediately. At the installation site, it must be ensured that objects in the neighbouring area or in the part of the building below are not damaged or flooded if water escapes from the water treatment device or the connection pipe. WilTec GmbH is not responsible for detrimental effects and damage caused by a fault of the drain or a wrong installation.
  • As shown in the illustration below, the drain pipe and the overflow pipe must be secured with ring clamps to prevent leakage during water drainage.naturewater 63920 Water Treatment Device - Wall fastening
  • Before connecting the water supply pipe, remove any dirt and dust remaining in the pipe. Then close the main valve before connecting the system.
  • The overflow and drain pipe must be provided with a free pipe guide. The length of the pipe may not be increased, and the pipe diameter may not be reduced without authorisation.
  • For the pipe connection, the pipe should be as close to the wall as possible, the pipe should run straight, and the angles should be free. After installation, the pipe should be fixed to the wall with a ring clamp. Pay attention to the height and placement angle of the pipe when it is connected. There should be no obvious stresses after connecting the pipe to avoid water pipe bursts and water leakage from the treatment device or pipework due to stresses in the pipework during long-term use.
  • It is forbidden to combine the overflow and drain pipes in one pipe and insert it into the wastewater outlet.
  • If the waste-water pipe or floor drain is blocked, the water treatment device must not be used.
  • After installation, check whether water is leaking from the connection nozzles, the connection between the control valve and GRP tank (glass fibre plastic) and the bypass connection.
  • Seals are usually installed when connecting threaded parts. It is therefore not advisable to apply too much force, as this can easily lead to the thread slipping and cracking.
  • The waste-water pipe must be level and there must be an air gap between the waste-water pipe (overflow pipe) and the waste-water outlet.
  • The waste-water pipe (overflow pipe) must not be connected to the sewage system in a sealed manner, as otherwise the machine can no longer work normally or the waste water can no longer flow back to the machine due to the negative pressure.

Installation

The water treatment device must be installed, tested, and put into operation for the first time by a specialist.
The following installation steps are only intended as a guide (using a PPR pipe as an example).

  1. Install the water-inlet and -outlet pipes on the wall according to the actual height of the product above the floor (sold separately). naturewater 63920 Water Treatment Device - floor

  2. Treatment of bypass valves in special cases: In the event of a failure of the device or other special circumstances, the bypass valve of the machine can be set to the bypass state (push the pull rod to the operating position as shown in Fig. 2). You can temporarily use the municipal water supply directly. Once the fault or problem has been rectified, set the bypass valve to the operating position (push the pull rod to the position shown in Fig. 1) to restore the clean-water supply.
  3. The general installation scheme is divided into two installation methods (as shown in the figures below).
    naturewater 63920 Water Treatment Device - divided | Name| | Name
    ---|---|---|---
    1| Adaptor| 2| Clamp

If an operating room is available, it is recommended to use the installation method shown in Figure 3. Otherwise, the drain pipe can only be inserted into the floor drain. As shown in Figure 4, make sure that the two pipes are fixed to the wall to prevent the pipe from being flushed out of the floor drain when emptying. This can have detrimental effects and lead to damage.
Install connections

  • The connection and laying of the pipe system is carried out in accordance with the provisions of the construction standards for water supply and drainage pipes. The inlet and outlet interfaces of the water treatment device and the water pipe interfaces are connected by a ¾″ PPR inner pipe or a corrugated pipe and must be installed on the same axis (see installation plan). The inlet and outlet points must not be installed in reverse.
  • Connect the water inlet and outlet pipes, the drain pipes, and the overflow pipes in sequence to ensure that all connections are tight and that there are no leaks. It is recommended to use flexible pipes to connect the water treatment device inlets and outlets, the drain, and the overflow (note: 304 stainless steel, alloy forged steel, high-strength engineering plastics, and other materials are to be used for the connection of pipe fittings and valves; valves and pipe fittings made of iron are strictly prohibited).

Installing the drain and overflow pipes

  • First loosen the clamp and insert it into the pre-fixed pipe, then insert the pipe into the drain connection to the floor, and finally turn the clamp onto the connection of the pipe and drain connection and tighten it firmly. The drain pipe must be secured with a clamp. ( Note! This procedure is intended to ensure that the hose is not pushed away or pushed out of the sewer if the flat is connected to the sewer or the water pressure of the floor drain is high).
  • The position of the control valve must be higher than the floor drain and the length of the drain pipe must not exceed 2 m. The installation of shut-off devices in the drain pipe is strictly prohibited. The sealing of the pipe fittings may only be made of PTFE.

Instructions for first use

  1. Initial settings of the operating system
    When the treatment device is switched on for the first time, the system indicates that water is being added. Press the button to access the operating system and set the current time and rinse time.

  2. First water supply for water purifiers
    Before the first water supply, close the water inlet valve of the building and switch the valve to the “water supply” operating mode. Unlock the system, press the button to start backwashing; “system is backwashing” appears on the display panel. Open the water inlet valve slowly to ¼ (opening it quickly can damage the appliance and lead to loss of activated carbon). At the beginning, the sound of slowly escaping air should be heard in the drain pipe. After the air in the GFK tank has escaped (i.e., when the water in the drain pipe flows out evenly), the water inlet valve should be fully opened.

Attention! If the water inlet valve is fully opened directly, the water will flow into the purifier too quickly, causing the activated carbon in the tank to be stirred up, which will easily cause damages. It is therefore necessary to open the water inlet valve slowly ¼ to allow the water to flow slowly into the tank, release the air in the tank and fill the tank with tap water. During backwashing, the water flowing out of the outlet pipe must be checked several times until it is really clean. The backwash time should not be less than 5 min.

Maintenance

  • Regularly check the water treatment device to control if there is a water leak in the water treatment pipe or if water is seeping through – if this is the case, contact a specialist.
  • The recommended service life of the activated carbon is 1–2 years. It should be  eplaced regularly according to the local water quality and actual water consumption.
  • As the product is updated regularly, the actual product may differ from the instructions.

Note! As the pressure in the water pipe fluctuates (the water pressure is generally higher at night than during the day), it is advisable to check the individual connections for leaks two days before installing and commissioning the appliance.
Function and meaning of the control panel
The functions and parameters of the water treatment device are set both in the foreground and in the background. The foreground mode is intended for users. Only the current time, the regeneration time, the raw water hardness, and other parameters can be set.
