2.3 Installing the Wireless On/Off Switch
The Wireless On/O Switch can be installed up to 25 metres away from the Water Valve Control. The distance over which the wireless
signal will work will depend on a number of factors including building construction, position of the Water Valve Control and Wireless On/
O Switch and in some instances the eect of interference from other wireless or electronic devices.
Test the wireless signal between the Wireless On/O Switch and the Water Valve Control before installation by temporarily
positioning them in the location where they are intended and repeating the wireless signal test given in Section 1.5.4. All
components should be positioned as high as possible o the ground to maximise the wireless signal.
The Wireless On/O Switch can be screwed to a surface or a standard back box, or xed to the wall using the double-sided adhesive
xing pads supplied. The switch should be positioned with the LED light at the top. N.B. Screwing the switch to an uneven wall can result
in cracking the fixing plate.
2.1.1 Extended range system
Install the valve as described above. Locate and fix the Valve Driver within 1.5M of the valve and at the highest practicable point off the
floor to maximise the wireless signal. Plug the valve into the Valve Driver connection cable.
Position the Water Valve Control ensuring that it is within wireless range of the Valve Driver and any Wireless Leak Detection Transmitters
or Wireless On/Off Switches that are being installed.
2.2 Installing the Flow Sensor (if installed)
The Flow Sensor is usually installed after the Valve, but can be installed either before or after the valve depending on the available amount
of room on the pipe. If room permits the Flow Sensor can be connected directly to the valve as shown (Figure 7).
If space is limited the sensor can be located on the pipe separately to
the valve. However, it must be positioned before any tee o points and
its’ connecting cable must be able to reach the Water Valve Control.
It can be mounted horizontally or vertically.
THE FLOW SENSOR MUST BE ALIGNED SO THAT THE
FLOW IN THE PIPE IS IN THE SAME DIRECTION AS THE
ARROW ON THE SENSOR BODY.
Connect the Flow Switch to the input marked “F” on
the bottom of the Water Valve Control.
Figure 7.
2. INSTALLATION INSTRUCTIONS
2.1 Installing the Motorised Valve and Water Valve Control
Install the Motorised Valve as close to the incoming stopcock on the incoming water main as possible, on the property owner’s side.
LeakSafe recommend the use of compression joints when installing the Motorised Valve although soldered, speed t or similar couplings
can be used.
Install the valve with the blue actuator positioned for easy access to the manual operating button and a clear view of the window that
shows if the valve is open or closed (Figure 10). DO NOT hold or use the blue actuator when tightening any connections as this will
damage the valve assembly.
Locate the Water Valve Control at the highest practicable point o the oor to maintain a strong wireless signal.
Using the back plate of the Water Valve Control as a template, x two screws (not supplied) on which to hang the unit. Do not over tighten
the screws, It is important to be able to remove the Water Valve Control by lifting it o the screws.
Connect the valve to the input marked “V” on the bottom of the Water Valve Control.

2.5 Assembling Leak Detection tape and connecting cables:
Tools required:
Crimping plier suitable for securing red pre-insulated terminals (bullet
connectors).
NB. If lengths of leak detection tape are being daisy chained together
with interconnection cable between each length of tape, you will also
require:
•Red 0.5 - 1.5 mm² Insulated Male and Female Crimp Bullet
Connectors/Terminals with a copper sleeve and ared vinyl
insulation.
•2 core audio cable.
Assembly (see Figure 9)
1. To connect the 1.5M connection cable to a single length of leak
detection tape crimp the female bullet connectors at the end of
the connection cable into the male bullet connectors on the leak
detection tape.
Plug the connecting cable in to Input “L” on the Water Valve
Control or the cable on the bottom of the Wireless Leak Detection
Transmitter.
2.4 Installing a Wireless Leak Detector Transmitter and Leak Detection tape
A Wireless Leak Detector Transmitter and Leak Detection tape can be installed up to 25 metres away from the Water Valve Control. The
distance over which the wireless signal will work will depend on a number of factors including building construction, position of the Water
Valve Control and Wireless Transmitter and in some instances the eect of interference from other wireless or electronic devices.
Test the wireless signal between the Wireless Leak Detector Transmitter and the Water Valve Control by temporarily
positioning all the components in the location where they are intended and testing in those locations before installation
(Section 1.6). Position the transmitter as high as possible o the ground to maximise the wireless signal.
Installation
Fix using self-adhesive xing pads or Velcro. Ensure that the transmitter’s connection cable hangs vertically and the Leak Detection tape
can be positioned where needed.
Figure 8. – Leak detection tape components
2. To connect the 1.5M connection cable to two lengths of leak detection tape to make a longer length of tape, crimp the female bullet
connectors at the end of the cable into the male bullet connectors on the rst length of leak detection tape, then crimp the test pins
of that tape in to the female bullet connectors on the next length of tape. A maximum length of 30M of tape can be connected in this
way.
Connect to the wireless Leak Detection Transmitter or Water Valve Control as detailed above.

3. RESETTING AND OPENING THE VALVE AFTER A LEAK ALARM
The Water Valve Control will shut the valve on the incoming water main or pipe if a leak detection tape is in contact with water, or if the No
Flow or Continuous Flow set times are exceeded.
3.1 Resetting the system after a leak has been repaired or Continuous Flow limits are exceeded
1. Press the “WATER OFF” button on the Water Valve Control to mute the alarm – the valve remains closed. If the alarm continues, and
you have a detection tape directly connected to the Water Valve Control, disconnect the tape then press the “WATER OFF” button on
the Water Valve Control to mute the alarm.
2. Identify where in the property the leak has occurred.
3. If you have wireless leak detector transmitters installed the one that has instigated the alarm will be beeping. If none of the
Transmitters are beeping but you have a leak detection tape or tab directly connected to the Water Valve Control then this is where
the leak is.
4. Repair the leak and dry the leak detection tape. Tapes should be unplugged and dried either naturally, or with a hairdryer on a
medium setting held 1M away from the tape, or on a warm (not hot) radiator.
5. Reposition and reconnect the tape once dry.
6. Press “WATER ON” on the Water Valve Control to open the valve.
