Quick Start Guide:
For your convenience operating instructions are also included on the side of the receiver.
Transmitter Operating Instructions:
1. Remove protective caps from transmitter
2. Connect transmitter to nearest water outlet using kit supplied with transmitter
3. Turn on water and loosen adjustment lock nut near T-handle
4. Turn T-handle clockwise until water flows
5. Turn T-handle counter-clockwise until water pulses several times per second; tighten lock nut
Receiver Operating Instructions:
1. Turn ON/OFF knob clockwise to activate.
2. Initial meter reading indicates battery condition.
3. To replace battery, loosen battery release button, move housing upward to expose battery.
4. Begin initial tracing about 2 meters from transmitter or any other area where pipe location is
known.
5. Push spike of receiver into ground near known pipe location and turn ON/OFF knob clockwise for
mid-range meter reading. Starting with the headphone volume sensitivity at a low level, adjust the
controls for comfortable listening level. Each earpiece has its own adjustment.
6. To pinpoint pipe position, use receiver to probe ground until you find peak (maximum) meter
reading. You will also hear the pulsing sound (similar to a heartbeat) grow louder.
7. Trace the pipe by establishing the direction of pipe route by probing every one to two meters to
locate a peak meter reading. Adjust the ON/OFF knob to maintain a mid-range meter reading.
Notes and Precautions:
•The RD500 is for use on water pipes only.
•It works best on water pressures in the range of 3 to 7 bar, (44 to 100psi); maximum pressure 10
bar, (145psi).
•The Transmitter pulsating effect causes pipe movement. If used for extended periods or on
substandard plumbing systems, leaks may result.
•RD500 readings do not indicate depth and the RD500 does not detect buried electrical power
lines, gas lines or other hazardous underground objects, so always dig carefully in the proximity of
buried pipes or cables.
•Use caution while wearing headphones and be alert to traffic or other hazards that are normally
heard outdoors.
•Always stand clear of all transmitters, adapter kits and hoses while they are connected to water
systems and operating. Ensure the drain hose is secured with a heavy object.
•On all hose bib applications, within 15 meters (50 feet) of a building, the proper low-power
transmitter (GREEN) and faucet damper MUST be used.

Transmitter Application Techniques:
Transmitters are connected at sprinkler heads, hose bibs, water meter bases, fire hydrants and clean-
outs. Supplied transmitter adapter kits are illustrated later in this manual. Always flush any connection
site until the water that flows is clear of all rust, silt, sealing compounds and foreign materials before
connecting a transmitter to the water line.
All adapter kits are supplied with a 3 meter (10 foot) high-pressure drain hose that must be connected to
the outlet of the transmitter in order for the device to work properly. Always use a weight on the hose or
tie the hose down to prevent the hose from whipping.
Check the water pressure before attempting to locate the water line and make sure that it is in the
operating range of the transmitter, which is 3 to 10 bar (40 to 140 psi).
The transmitters are color-coded to identify their intended usage: A color-coded ty-wrap is used along
with a small square area that is painted on the side of the transmitter to indicate the colour. Green is the
lowest power transmitter and is intended for use on sprinkler and hose bib pipes that typically range in
diameter between 1.3cm and 5cm (0.5 inches and 2 inches). Green transmitters may be may be used on
larger diameter pipes where reduced operating range is acceptable. Yellow transmitters are intended for
use on water mains that range in diameter between 5cm and 15cm (2 inches and 6 inches). They are
typically connected at a water meter connection. Yellow transmitters should never be used on smaller
diameter pipes, but they may be used on larger diameter pipes. Red transmitters are intended for use
only on water mains that are 15cm (6 inches) in diameter or larger. The typical connection is via a fire
hydrant.
Always start your adjustments by turning the T-handle clockwise until full water flow is attained at the
transmitter outlet. Then, slowly turn the T-handle counter-clockwise until the transmitter begins to pulse.
Once the pulsing begins, turn the handle very slowly in each direction to fine tune the pulse to a regular
beat of about two to five times per second. This adjustment range varies between less than one turn to
several turns depending on the operating conditions. If you turn the T-handle too far in the clockwise
direction, water will flow continuously without pulsing, and if you turn the T-handle too far in the counter-
clockwise direction, water flow will stop completely.
The best results are obtained with the slowest pulse possible. Range and signal strength are greatly
improved with low pulse rates of a few pulses per second. Higher water pressures typically cause faster
pulse rates. Pulse rates above 10 pulses per second are difficult to use and cause reduced location
range.
The transmitter contains a locking collar located directly below the T-handle. Tighten the hex-shaped
collar to prevent the T-handle from moving (walking) while pulsating.

Receiver Application Techniques:
Two devices are provided for probing the surface with the RD500 receiver. A 14cm (5.5 inch) ground
spike is supplied for soft surfaces and a brass hard surface plate is included for hard surfaces such as
concrete or tarmac (asphalt). The hard surface plate has concentric recessed channels in its surface that
allow it to be positioned such that it lays flat against surfaces.
The RD500 is supplied with high quality headphones that have independent volume adjustments on each
ear piece. Using non-standard headphones may reduce system performance, create oscillation in the
audio output and cause mechanical damage to the headphone jack.
Pinpointing pipe location is difficult without using the meter to measure signal level. It is very difficult for
the average person to discern slight variations in audio signal levels. Always adjust the sensitivity so as
to maintain a mid-scale meter reading while locating. Typical location accuracy is plus or minus one pipe
diameter. Always probe or expose the pipe to confirm the exact location before performing any
excavation.
Best location results are obtained by beginning the trace at least 3 meters (10 feet) from the location
where the transmitter is connected. The signal levels are normally too strong in the area immediately
surrounding the transmitter. Alternately, tracing may begin at a known pipe location that is not more than
75 meters (250 feet) down the pipe from the transmitter.
The preferred method for tracing pipes is to locate at least two known pipe locations that indicate the
heading or direction that the pipe is laid. Readings should be taken along an imaginary line that runs
perpendicular to the pipeline. Confirm a peak signal reading by taking additional readings that are equal
distances from the peak location. These readings should be lower than the peak reading and
approximately equal.
Once the pipe direction is determined, it is possible to quickly trace the pipe along this heading and
confirm any changes in direction by periodically taking readings.
Always transport and store your receiver in the carrying case to protect it from damage. If the receiver is
allowed to fall over and strike a hard surface it may permanently damage the meter.

Safety Information
To prevent injuries to yourself and others or damage to your device, it is important that you read all safety
warnings, cautions and notes before use.
WARNING
Warnings alert you to possible personal injury.
You are responsible for determining whether the conditions are suitable for using the RD500. Always
carry out a risk assessment of the site to be inspected.
Subsurface utilities: Before inserting the RD500 into the ground ensure there are no shallow cables or
services that could be damaged by the spike.
This equipment is NOT approved for use in areas where potentially explosive (or otherwise hazardous)
gases, vapors, liquids or solids may be present.
Headphone use: you need to remain alert to traffic and other hazards that are normally heard outdoors.
Always turn the volume down before plugging headphones into an audio source and use only the
minimum level necessary to take your measurements. Excessive exposure to loud sounds can cause
hearing damage.
Do NOT carry out any measurements on components carrying live voltages.
The RD500 does not indicate the depth of the pipe. Additionally, it does not detect buried electrical power lines,
gas lines or other hazardous underground objects. If you intend to uncover the pipe by digging, you must follow
your company, region and country’s codes of practice for excavation.
Always use a weight on the draining hose or tie the hose down to prevent the hose from whipping.
Stand clear of all transmitters, adapter kits and hoses while they are connected to water systems and
operating.
