Installation Guide

SECTION 1-Planning the Installation
The SME LD20-D Leak Tracker system has two basic components, an intelligent Detector Valve and a Remote
Controller. For maximum protection the Detector Valve must be installed in the cold water riser as close as
practical to the point where the riser enters the property after the water meter and main shut off valve but
before any branch line, in this way all water runs and point of use outlets within the property will be monitored.
The Leak Tracker Detector Valve must not be installed in the hot water branch line.
If your home is fitted with any of the following they must be considered in the installation:
Sprinkler System - If the cold water riser supplies a fire sprinkler system in the property the Leak Tracker
Detector Valve must be installed after this branch.
Water Softener - If a water softener is installed in your home water can flow depending on the make and
model for up to 60 minutes during the regeneration process. The Leak Tracker will consider this regeneration
flow as a normal condition and will set its-self accordingly if the auto set-up feature is used. This means
that whilst the “real” water use in a property may only be for a maximum of 15 minutes at any time the Leak
Tracker will operate on a reduced sensitivity based on the water softener requirements rather than the “real”
flow pattern for the home. This “unreal flow” can be eliminated by installing the Leak Tracker after the water
softener.
Irrigation System - Lawn and general irrigation systems present the same problem as water softeners and we
recommend that the irrigation branch run is taken off before the Leak Tracker
Climatic Conditions - Both the Leak Tracker Detector Valve and the Remote Controller must be installed in an
area that is protected from freezing temperatures, rain, snow and direct sunlight.
Old Steel Systems - If the Leak Tracker Detector Valve is to be fitted into an old galvanized iron system or if
debris is likely to be a problem in the system a Y- type filter of the appropriate size should be installed before
the Detector Valve in the riser. Valves will be required either side of the Y-type filter to allow the filter element
to be periodically cleaned.
Depending on the specification of the plumbing system in your home (copper, galvanized iron, CPVC or PB)
fittings will need to be purchased to fit the Leak Tracker Detector Valve into the existing pipe-work; fittings are
readily available through your local plumbing supply store. If you are unsure or have galvanised iron or PB
pipe work we would advise that you contact a professional plumber.
As the Detector Valve is battery operated (4 x AA cells: 1.5V not supplied) there is no restriction as to where
it can be installed relative to available power outlets.
Should the optional power pack be specified the Detector Valve must be installed within 6 feet of a 110-volt
alternating current wall mounted (not ceiling mounted) power outlet. Do not use a trailing lead if a power
outlet is not within 6 feet of the Detector Valve you must have one installed by a professional electrician in
compliance with building codes.
As the Remote Controller “talks to” the Detector Valve by radio frequency (RF) the Remote Controller may be
plugged in to any wall mounted (kitchen, hall, diner) 110-volt alternating current power outlet within the living
area of your home that is no more 100ft in a straight line from the Detector Valve.
Under certain circumstances the type of building materials used in your home may block the RF signal in a
specific location, if a signal cannot be received move the Remote Controller to a new location.
Both Detector Valve and the Optional Power Pack must only be used in
wall mounted 110 Volt alternating current power outlets.
The Detector Valve and the Remote Control are factory registered to each other in the same way as are
cordless telephones and will only work together; serial numbers are affixed to both parts for identification
should the parts become mixed.
Note: Before you start the installation ensure that you have all the fittings and expertise to complete the
project as once started the water to your home will be shut-off until the project is completed. If you are
uncertain about any aspect of the installation you may wish to hire a professional plumber to undertake the
installation of you Leak Tracker Detector Valve.

REMOTE CONTROLLER
1. Protective Button Cover Flap. To ensure no accidental control
inputs can be made to the system keep the protective flap closed during
normal use.
2. Valve Close Button. Use of this control will shut off the incoming
water supply. The valve must then be manually reset.
To ensure reliable service the valve must be tested once every month by
pressing this button. Failure to do this will invalidate the Guarantee
3. Manual / Auto Selector. When pressed, this button will alternately
select either manual or auto modes. The selected mode will be indicated
by an illuminated LED 15 or 11.
4. Manual Time Adjust. (Use in manual mode only) Pressing this button
repeatedly will select the desired water flow time on the time display (7).
This time is the time that water is allowed to flow continuously before the
alarm is sounded indicating a problem. The valve closes after a further 10
minutes if the reset button is not pressed cancelling the alarm. If during
this manual mode no flow occurs for 12 hr, the flow control time will
automatically set to the minimum time setting of 15 minutes. The initial
setting is then restored following the first usage of water.
