Leckage-Protection Offline for Gate Valves

SKU: KFRFLO01
Version: 1.0

1. Product Description

The offline leakage protection system 'KFRFLO' detects water leaks using multiple water sensors distributed throughout the house and shuts off the water supply in the event of a leak. The unique feature of this system is that it does not require an app, internet, or Wi-Fi.

The retrofit motor is installed in place of the handwheel on the main shut-off valve. The product bundle includes three battery-operated water sensors that are paired with the motor and distributed around the house.

Communication between the sensors and the motor uses the highly reliable, standardized LoRa wireless technology, specifically designed for such applications. No additional equipment like a gateway is needed. All sensors communicate directly with the motor in case of an alarm, making the system installation very straightforward.

In the event of an alarm, the affected sensor emits a loud audible signal and flashes red. The motor shuts off the water, also emitting an audible signal and flashing red. The alarm can be cleared, and the water turned back on by pressing the button on the motor.

3. Installation of the motor


3.1. Mounting the motor on the valve

The motorized actuator can be used with all commercially available angle seat valves. However, due to the variety of mechanics, certain adaptations must be made. For installation, leave the valve open or rotate it to the open position. Plumbers recommend that the valve is fully opened first and then lightly closed by turning it clockwise approximately 2 turns.

  1. Remove the center screw from the hand wheel. Some manufacturers do not use the typical green handwheel. However, the metal stem is always hidden under the plastic. Keep the screw for future use.
  2. Remove the handwheel.
  3. Select one of the 4 adapters (A1...A4) for wrench size M17, M22, M27, or M30 that fits snugly on the bottom of the valve bonnet (hexagonal or rectangular shape). If none of the supplied adapters fit the valve, please take a picture, and send it to support@aqua-scope.com. This helps us to develop and manufacture adapters for valves we don't know yet. In the meantime, there is a solution to the problem. See section 'Make an adapter if no adapter fits' below for instructions.
  4. Select the correct ball bearing seat (W1 ... W3) and place it on the stem. If your stem is larger than the 8x8 mm required by the largest bearing seat, the KFR cannot be used on your valve. If your stem is even smaller than the smallest ball bearing seat of 6x6 mm, you can solve the problem in the same way as for the adapter. See instructions below.
  5. Tighten the ball bearing seat with the screw from step 1.
  6. Depending on the size of the valve bonnet and stem, you may need additional distance rings (D1, D2) on top of the adapter ring. If the inner coupling (K) cannot be pushed all the way into the main body (G) without sitting on the valve body, or if the main body cannot be connected to the adapter ring already installed, a distance ring (D1 or D2) must be placed between the adapter ring (Ax) and the main body (G). This is usually the case with rising stem valves. The spacers are 12 or 24 mm, and they can be combined. Use the spare handwheel to open and close the valve for verification.
  7. Place the housing on top of the adapter or distance ring.
  8. Place the inner coupling in the housing. It must pass over the ball bearings in both the open and closed positions. The housing is clear to check this. If it does not fit, use other distance rings in step 6. Please use the spare handwheel to open and close the valve to check.
  9. The bracket is required to hold the entire assembly in place if the valve is not installed in an upright position. It is recommended that the bracket be used in any case. Tighten around the pipe using the two zip ties provided. You can remove the zip ties at any time.
  10. Finally, place the motor on top of the housing. You may need to turn the inner coupling a little if the motor does not fit right away.


3.2. Detecting the endpositions of the valve

Each time the motor is disconnected from power, it will determine its current position. It briefly moves in the 'Close' direction. If this is not possible, the motor defines the current position as the 'Open' position. The next 'Close' command will fully close the valve. On the following 'Open' command, the motor will move to the previously defined 'Open' position. This allows you to set the 'Open' position of the valve yourself by only opening the valve as far as necessary and then reconnecting the power, making this self-chosen position the 'Open' position.

If the motor detects a closed valve when power is connected, it will open to the valve's full-open position on the next opening command and then close it back by two turns, as currently recommended by plumbing professionals. The factory setting allows a maximum of 10 turns between 'Open' and 'Close.' This value can be adjusted if necessary via configuration parameter 9.


3.3. Make an adapter if no adapter fits

The product is supplied with a portion of epoxy. This is a two-part mixture. Mix the two components by kneading until the mass has a similar color. Select an adapter ring that just fits over the base structure of the valve bonnet and fill the gaps with the prepared epoxy. Allow the epoxy to cure. Note that the epoxy will adhere to the metal body. If you do not want the epoxy to stick, coat the metal body with some oil to allow easy removal of the epoxy filled adapter.

In the same way, you can put epoxy in one of the bearing seats if your stem is smaller than the is smaller than the 6x6mm of the smallest seat. Make sure the stem is positioned right in the centre of the ball bearing seat.


3.4. Valves from Wilhelm Ewe GmbH and Co. KG

This company's valves have a very special design. You must insert the split ring (E1+E2) into the 24 mm distance ring (D1) instead of using one of the adapters A1 ... A4. No further distance ring is needed but a small ring DE must be placed below the ball bearing seat to hold down the large fat chamber.


4. External wired Flood Sensor

The unit allows an optional wired flood sensor to be attached. There is a connector on the power cord next to the motor. Remove the blue protective pad and plug in the sensor. Please use some force to push the connector to ensure a waterproof connection. If the sensor head detects water, a flood alarm will sound, the valve will close, and the alarm will be indicated by a buzzer and LEDs. Once the sensor head is free of water, you can clear the alarm by pressing the button for 2 seconds. It is also possible to clear the alarm with a wireless LORA command. In both cases, an Alarm Clear report is sent uplink to the LORA network.


5. Manually Operating the motor

You can open or close the valve by briefly pressing the button. If you press the button while the motor is running, the motor stops moving and will reverse direction with next push.

The unit must be calibrated to recognize the end positions of the valve. Once these end positions are known, the motor will stop softly at that position and not "slam into the wall" to protect the mechanics and ensure long life and reliable operation. After power up, the unit will make some short movements to determine if the last position was open or close. The first open or close operation is used to perform calibration for both end points. No special user interaction is required for calibration.


6. LEDs

The unit has a two-color LED with the following meaning


7. Installation and Pairing of the Flood Sensors

The system comes with three water sensors by default, but additional sensors (product code FLOLWE02) can be ordered from the Aqua-Scope shop.

The first step is to insert the CR123 battery. Turn the top of the sensor housing counterclockwise to open the housing. Inside you will see the functional components of the unit:

  1. CR123 battery holder. Be sure to insert the battery with the correct polarity. Inserting the battery the wrong way will not damage the electronics, but will drain the battery without any function.
  2. Button
  3. Dual Color LED
  4. Buzzer Sound
  5. Computing/Communication Module

After inserting the battery (resp. removing the isolating slip), the device is ready for operation. You can check the function by hitting the button. You will hear a beep and the LED goes on

  1. Press the pairing button: Hold the button while inserting the battery. The red and green LEDs will blink simultaneously.
  2. Click the motor button twice: This will generate a long tone from the motor, and the two LEDs on the sensor will turn off, indicating a successful pairing.
  3. Repeat this process for all water sensors you want to pair. You can connect an unlimited number of sensors to the motor.

When water is detected an alarm packet is sent out, the LED turns red and the device continues beeping.

Close the housing by turning the top of the housing 1/8 turn clockwise.


7.1. Recommended places to position the sensors:

The sensors can either be placed directly on the floor or mounted on the wall using the provided bracket. For wall mounting, the sensor cable needs to be plugged into the bracket, with the socket ideally pointing downwards.
