How the System Works
Flood sensors constantly monitor their selected areas
for accumulating moisture. When a leak is detected,
a sensor will send a radio frequency signal (RF) to the
WaterCop® Pro Water Control Panel, instructing it to
close the Brass Valve, shutting o the water supply to
the home. The WaterCop® Pro Valve will remain closed
until it is reset manually or through the Water Control
Panel. The wireless sensors are battery powered
devices, enabling them to be located anywhere a leak
is likely to occur, or where water might cause damage.
The WaterCop® Pro Actuator is powered through
the Water Control Panel, which requires household
electrical power (common 115 VAC, grounded outlet)
and will not operate during a power outage unless
receiving auxiliary power from a backup device such as
an Uninterruptible Power Supply unit (UPS). Additionally,
the use of a certified surge protection device is highly
recommended.
Operating the WaterCop®Pro
The normal position of the valve is open to allow full
flow throughout the plumbing system. The manual
override handle on the top of the WaterCop Pro®
Actuator will show the position of the valve (in-line with
the pipe means the valve is open; when the handle is
not in-line it is not fully open; when it is perpendicular to
the pipe, the valve is fully closed).
When leaking water comes into direct contact with a
flood sensor’s probe, an RF signal is transmitted to the
Water Control Panel and the valve closes, turning o
the water source to protect the building from additional
water damage. The red indicator light will signal that
the valve is now in the closed position. The valve will
remain closed until the unit is manually reset (through
the manual override handle or the OPEN button on the
Water Control Panel).After the plumbing problem is
fixed, reset the WaterCop Pro® by pressing the OPEN
(green circle) on the face of the Water Control Panel.
NOTE: If major repairs are needed to correct the
plumbing system, it is recommended that the main
shut-o valve upstream of the Actuator also be closed
during the repairs. Close the main water shut-o valve
and unplug the Water Control Panel before making
repairs on the plumbing system.
In case of a power failure, use the manual shut-o valve
to turn the water o in case of an emergency. When
power is restored, the WaterCop® Actuator will remain
in its last known position indicated by the red or green
lights on the face of the Water Control Panel.

To Power and Program
Wireless Sensors
WaterCop® Pro wireless sensors are addressable. This
means that the WaterCop® Pro Water Control Panel can
tell you the operational status of each wireless sensor. If
you have many wireless sensors, this feature will quickly
tell you where the leak is located or warn you if a sensor
requires service (low batteries). It is important that you
introduce each wireless sensor to the WaterCop® Pro
Water Control Panel and document the sensor (the
transmitter and the sensor probe together; not just
the probe) number on the transmitter. Once placed
in location, you will also note this information on the
Sensor Location Log (included).
Once the wireless sensors are programmed, you will be
able to place them in desired locations to monitor your
home or business for water intrusion.
Powering Wireless Sensors
WaterCop® Pro wireless sensors require power to
operate. Use either fresh AA alkaline batteries (not
included) and/or a WaterCop® Pro Sensor AC Adapter
(sold separately) to power. If both are used, batteries
will provide back-up power in the event AC power is
lost. Rechargeable batteries are not recommended.
To install batteries, remove the battery cover located
on the back of the sensor, and install batteries in
accordance with the (+ and -) placement guide. Reinstall
back plate. Instructions on how to connect AC adapters
are included in this manual.
It is important that you number each sensor (not each
sensor probe) for easy identification while programming.
The WaterCop® Pro System is capable of supporting as
many as 45 wireless sensors. Additional wireless sensors
can be added in the future by repeating the steps taken
in this section. Please contact your local dealer or
DynaQuip® Controls to inquire about additional sensors.
Once each sensor is powered and numbered, you
are ready to begin programming the sensors to the
WaterCop® Pro Water Control Panel.
Programming Hardwired Sensor Probes
for the Hardwired Water Control Panel
•First, while the power is o install all sensor probes.
•Connect the power to the Water Control Panel.
•Short each probe using a conductive metal surface
until the display reads “WIREPANEL SHT” and the
corresponding light on the side of the panel lights up.
•Repeat for all sensor probes.

7
Programming Wireless Sensors
Plug the WaterCop® Pro power supply into a nearby
115 VAC outlet.Depending upon the position of the
valve, the Actuator may initially turn the valve when
first powered. BE EXTREMELY CAREFUL TO KEEP
FINGERS AND OTHER ITEMS OUT OF THE VALVE.
The display will read WaterCop NORMAL.
•To add sensor #1, Press MODE twice (DEVICE ADD
will display on the LCD).
•Press CLOSE once (DEVICE #1 ID= will display on
the LCD).
•Short (using a conductive metal surface) one sensor
probe on each sensor by touching the leads with metal.
Do not get the sensor wet – it must be shorted. The
sensor will beep and the LCD will display SEN #2
SHORT 2, then remove the short and LCD will display
DEVICE STATUS SENSOR #1 OK!
•To add sensors #2 through #45:If time has passed,
the Water Control Panel LCD will revert to ready mode
displaying WaterCop NORMAL.To add more sensors,
you will need to return to program mode and repeat
steps used to add sensor #1. If LCD screen reads
SENSOR #1 OK!, push CLOSE to add the next
wireless sensor.
•Repeat above steps for all of your wireless sensors,
taking care to program them in the same order as
labeled. When finished, Press MODE three times to
return to the NORMAL mode.
To Remove Sensors
If you need to remove a wireless sensor for any reason,
follow these instructions:
•Press MODE three times (DEVICE REMOVE will
display on the LCD).
•Press CLOSE to cycle through the loaded sensors to
choose the sensor(s) you wish to remove.
•Press OPEN to remove the selected sensor from the
Water Control Panel’s memory.
•Press MODE one more time to return to the main
screen (WaterCop NORMAL).
•Hardwired sensors can be removed, however the unit
will need to be reset and all sensors reprogrammed.
Pre-Installation Testing of
WaterCop®Pro
Although each unit is pre-tested at the factory, it is
highly recommended that the unit be tested prior to
installation to ensure proper operation in your home.
Operating the valve before connecting it to the water
line will not damage it.
USE CAUTION! The valve closes with
enough force to cut o a finger. Be
extremely careful to keep fingers and
other items out of the valve.
Wiring Instructions
Water Control Panel
The WaterCop® Pro Actuator comes with a 25', 50'
or 75' cable for wiring into the Water Control Panel.
Following the color code in the wiring diagram, wire
each colored wire into the appropriate terminal.
To wire the Water Control Panel into an alarm system,
wire the two terminals titled ALARM into the security
system. The ALARM relay is a dry contact relay and
will only trip if water is detected or dead battery sensor
has turned the water o and the audial alarm turns on.
It will trip o when the valve is opened after water is no
longer detected. The TROUBLE relay will trip if there is
a short, low battery, or open situation.
If the power cord was removed from its terminals, the
positive wire is the one with the stripe on the insulation.
Do not reverse the polarity of the power cable.
Do not reverse the polarity if using optional adapter! The
positive lead is the one with the stripe on the insulation.
WARNING!

Screw
Installation of Sensor Probes
Follow the above wiring diagram to properly wire the non-polar wireless sensors. Be sure to completely wire the sensor
before power is applied; when power is applied, it searches for any and all attached sensor probes. If power is applied
before a sensor probe is added, it will not be recognized and will not be used until the power is reset. If more than one
sensor probe is wired to the sensor, the Water Control Panel will dierentiate between the two dierent probes with a
“1” or “2” after the status of the probe, e.g. SEN #1 WET 1 or SEN #1 WET 2.
Manually Testing the Valve
and Wireless Sensors
Manually Test the Valve
Check the Quick Start Guide for wiring and preliminary
testing of the Water Control Panel.To test your WaterCop®
Pro System, gently pull the safety plugs out from each end
of the valve. Check the position of the valve by looking
in either threaded end. In the open position, you will be
able to see through the valve; in the closed position, only
the shiny surface of the ball will be visible. Place the base
of the housing on a sturdy surface, as close as feasibly
possible to the location where it will be permanently
installed. Plug the WaterCop® Pro power supply into
a nearby 115 VAC outlet. The valve position indicator
lights should now correspond to the actual position you
noticed. Green = Open. Red = Closed. Grasp both sides
of the housing (not the valve) with the valve pointing
away from you for safety. Being very careful not to have
your fingers or other objects near the valve openings,
press the OPEN or CLOSE buttons; whichever has the
unlit light next to it. You will hear the motor change the
valve position. Again, look into the threaded end of the
valve to verify that the valve has changed position. If it
appears that the valve has not turned from one position
to the other, DO NOT try to reposition the valve yourself
by inserting any tool or fingers into the valve. Operate the
valve several more times from open to close, checking
each time for proper positioning. If you are experiencing
trouble getting the valve to open and shut, call the
installation help line listed on the back cover.
Manually Test the Wireless Sensors
WaterCop® Pro wireless sensors require power to
operate. Use either fresh AA alkaline batteries (not
included) and/or a WaterCop® Pro Sensor AC adapter
(sold separately) to power. If both are used, batteries
will provide back-up power in the event AC power is
lost. Rechargeable batteries are not recommended.
To install batteries, remove the battery cover located
on the back of the sensor and install batteries in
accordance with the (+ and -) placement guide.
Reinstall the back plate. Follow suggestions found in
the section titled “Placement of Wireless Sensors” for
recommendations where sensors should be placed.
Locate a wall near the area you choose to monitor.
8

9
Avoid high trac areas where the cord or sensor could
be stepped on or kicked. Mount the transmitter at a
convenient location on the wall, two to three feet above
the floor. This will help avoid damage to the sensor
body and provide a strong signal. Use the fasteners
included with the unit.
1. Following all safety precautions, make sure that
the Water Control Panel is plugged in and the
valve is in the open position. Leave the WaterCop®
Pro Actuator near your main water line, on a sturdy
surface. It is important that anyone who will be near
the valve is aware of the safety precautions, and
does not insert any object into the valve, or handle
the valve during the test.
2. At one of the locations you have chosen to monitor,
drop the sensor probe (not the mounted transmitter)
into a cup of water. Hold until you hear the sensor
transmit a signal to the Water Control Panel (about
5 seconds). This test simulates a leak and lets you
check for interference between the sensor and the
Water Control Panel.
3. Take the sensor out of the water and carefully dry o
the sensor probe’s prongs and hexagonal body.
4. Go back to your WaterCop® Pro Actuator and verify
that the valve has closed (the red indicator light
will be lit). The display will indicate which sensor
activated the valve.
5. Keeping all objects away from the valve, reset the
Water Control Panel by pushing the OPEN button.
6. Repeat steps 2 through 5 until you have tested each
sensor in the locations that you wish to monitor.
Troubleshooting
•If the wireless sensor does not close the valve, check
that the sensor has power and batteries and/or AC
adapter is installed correctly. Repeat test.
•If the batteries have power and the wireless sensor
still does not make the valve close, physically remove
it from its installed location and place it next to the
Water Control Panel. Repeat test. If the sensor operates
properly when it is closer to the Water Control Panel,
but not when it is installed at its remote location, try
moving the sensor to a dierent position or try a
dierent wireless sensor. Some possible causes of
signal reduction are steel construction, foil backed
insulation or other large metallic barriers.
You may also use a range enhancing repeater
(WPR – sold separately) to extend the eective
range of the wireless signals.
Installation of Wireless Sensor
Once testing is complete, finish installation of the
wireless sensors by unwinding the cord and placing
the sensor probe on the floor at the lowest point
(where water would naturally collect) in the area to be
monitored. Be sure that the sensor probe is placed
FLAT on the floor so water can be detected as soon
as it begins to accumulate. The sensor probe may be
secured to the floor with screws or adhesive tape,
taking care that the transmitter and wire are clear of
doors, drawers, sharp edges, or other hazards that may
cause damage. Unplug the Water Control Panel after
the testing is complete. The WaterCop® Pro can now
be installed into the plumbing system.
Prior to installation, read all warnings and precautions
carefully.
Placement of Wireless Sensors
Each WaterCop® can support up to 45 wireless flood
sensors. Additional sensors may be added at any time.
A sensor consists of a transmitter and a sensor probe
(see page 3). Wireless sensors should be placed in
locations where leaks are most likely to occur.
Suggested Locations
•Water Heaters •Dishwashers
•Toilets •Kitchen Sinks
•Bathroom Sinks •Ice Makers/Refrigerators
•Washing Machines •Pipes that are prone
•Automatic Humidifiers to freezing
Sensor probe can be placed under
dishwasher or near water lines
underneath the kitchen sink.

10
The transmitter in the wireless sensors and the receiver
in the Water Control Panel communicate by radio
frequency. The smaller the distance between them,
the stronger the signal will be. Transmission distance is
somewhat dependent upon the building layout and the
type of construction. The transmitter (the box attached
to the sensor probe) must be kept dry. It is NOT splash
proof. Sensors should never be placed outdoors.
The sensor probe detects the water from a leak and
is completely waterproof. Sensor probes should be
placed on the floor or in areas where water would tend
to accumulate rapidly in common leak or overflow
situations. Make sure that any water from a leak will
drain toward the sensor probe, not away from it.
Avoid high trac areas where the cord or sensor probe
could be stepped on or kicked and where children
or pets may disturb it. The sensor probe should be
placed FLAT on the floor so water can be detected
as soon as it begins to accumulate. The sensor
probe may be secured to the floor with screws. To
avoid damage to transmitters and to provide for the
strongest signal possible, the transmitter portion of
the flood sensor should be mounted in a convenient
location (on the wall, in a cabinet, closet, etc.) 2 to 3
feet above the floor (see illustration).
(See Installation section for details on sensor
installation.)
Wireless Sensor Battery Life
Fresh, high quality AA alkaline batteries are
recommended. Assuming the sensor has not detected
and transmitted a leak condition (standby mode); high
quality AA alkaline batteries should last between three
to five years. Each wireless sensor will communicate a
low battery condition to the Control Panel. In the event
the battery power reaches a critically low status, a
CLOSE signal will be transmitted to the WaterCop® valve
as a precaution. After replacing batteries, re-test each
unit in its regular location. Periodic testing of sensors is
required to monitor proper power and function.
Installation Procedure:
Indoor vs. Outdoor
Selection of WaterCop® Pro Valve
Installation Sites
The WaterCop®-ready Ball Valve should be installed
in the main water line just downstream from the main
shut-o valve in your home. The manual override
handle/position indicator should be easily accessible.
The installed WaterCop® Pro Actuator is completely
supported by the piping in your plumbing system.
The Actuator should NOT be used as a step or to
support heavy loads.
The shut-o valve must be installed:
•in the main water line;
•in place of or just downstream from the main water
shut-o valve;
•where it is accessible;
•where the case is protected from use as a step or
from other excessive loads;
•where it does not interfere with fire suppression
systems.
Local electrical and plumbing codes should be
consulted to ensure that the installation is in complete
compliance. (See Installation section for details.)
Review the Location and Type of Main Supply Line
The main supply line should enter the
house in either the basement or
a crawl space beneath the first floor.
The water main shut-o valve is
usually located near where the line
comes through the basement wall
or just after the water line enters
the living area from the crawl space.
In apartments, townhouses, and
manufactured housing constructions,
the water main shut-o valve can
usually be found in close proximity
to the water heater installation. The
WaterCop® Valve should be installed in
the main water line just downstream
from the main shut-o valve in your
home. The water supply must be
shut o prior to the installation of the
WaterCop® Valve.

NOTICE! Installation must be a minimum
of 18 inches downstream of a water meter,
if water meter is inside the premises.
The Water Control Panel should be placed in a
convenient indoor location to view the valve position
(open/closed) and be accessible for resetting after a
leak has been detected and corrected.
Additional Parts Requirements
Installation of WaterCop Pro® will require
additional parts. When the main supply line is cut
to accommodate the WaterCop® Valve, new fittings
will be needed to connect the ends of the piping
to the WaterCop® Valve.
The type of connecting fittings to use will be
determined by the type of existing piping, local
plumbing codes, and industry standard practices.
Compression Fittings
The unit can be installed with compression fittings using
common household tools and basic mechanical ability.
You will need:
•two fittings (male pipe thread x compression)
available at most local hardware or plumbing
supply stores;
•Teflon® tape or thread sealant;
•tubing cutter;
•ruler;
•pencil or marker;
•two large adjustable wrenches.
Measure the outside diameter of the copper tube and
note the valve size to be sure the proper size fittings
are purchased.
Steps of Installation using Compression Fittings
1. Remove nuts and sleeves from compression fittings
and install fittings into each end of the valve using
Teflon® tape or thread sealant to ensure a watertight
seal. Hold one wrench on flats of valve body and
use the other to tighten fittings.
2. Measure the distance from end to end of valve
assembly once fittings are secure. For ½" tube
(⁵/₈"outside diameter) subtract ½", for ¾" tube
(⁷/₈" outside diameter) subtract ¾" from your valve
assembly measurement. This is the length of the
section of tubing to be cut out of the existing line.
The piece of existing tubing is shorter than the
measured length so that the tube ends extend into
the compression fittings.
3. Select the location for the WaterCop® Valve and
Actuator. After cutting the section of tube out of
the line, you will need to shift the tube ends to be

Solder Fittings
An alternative method is to solder the unit into the
water line. This method requires a considerably higher
skill level to accomplish the installation properly and
safely. If you are not skilled in this area, it is strongly
recommended that you contact a professional plumber
to do this type of installation.
Electrical Connection
The Water Control Panel is supplied with a power
adapter. Consult local electrical codes as to the
necessity of ground fault protection. It is recommended
that the Water Control Panel not be plugged into an
extension cord. Review “Specification” current and
power requirements so as not to overload the circuit
supplying power.
Emergency Procedures
In the unlikely event that the WaterCop® Pro System
should shut o the main water supply and then become
inoperable due to a power outage or damage, it is
possible to manually operate the WaterCop® Pro to
return water service. Unplug the Water Control Panel
from its power source. The valve may be manually
operated by turning the manual override handle in the
direction indicated on the Actuator.
