INTRODUCING THE WATER WITCH
Thank you for purchasing a Water Witch electronic water
leveller. The Water Witch has been Australia’s most trusted
auto leveller for more than 20 years and is a product close to
our heart – it gave rise to our business and established our
reputaon for outstanding quality.
The Water Witch began life during the 1980s as the Neptune’s Mate
automac water leveller. As a pool builder I was frustrated with the poor
quality and reliability of levellers available at the me. Neptune’s Mate
prototypes were developed and tested in my shed at home unl we had a
suitable producon model. Aer a few years of producon, further tweaks
and improvements were decided upon. The Water Witch was born.
For the same reasons I developed the Water Witch, my industry friends
began installing them into their pools and water projects. Its popularity has
since soared and Cooke Industries has evolved from its Cookes Pools & Spas
heritage to become a strong, independent business.
The Water Witch proudly remains Australian made to ensure we control
producon quality and deliver the very best product to you. Thank you
for your support and we trust your Water Witch will deliver many years of
reliable service.

PRODUCT APPLICATIONS AND WARNINGS
The Water Witch is used in many dierent applicaons and projects to maintain a minimum
water level. Some of the most popular applicaons include:
• Swimming pools and spas •
Balance tanks
• Water features and ponds • Innity edge troughs
• Water / Splash parks • Commercial pools
• Irrigaon projects • Water tanks
Given the many suitable applicaons for the Water Witch, a quality installaon is required
to ensure performance is not aected by site condions or any other factor.
•
The Water Witch is manufactured
and tested to the highest
internaonal standards. Wear
and onsite condions, however,
may cause component failure. All
installaons must include sucient
overow provisions to ensure a
ooding event does not occur.
• Indoor pools and enclosed projects
must also feature sucient overow
provisions to avoid a potenal
ooding event.
• The Water Witch may not be
suitable for installaons where the
water source is connected to a
pressure pump. Conrm high and
low pressure readings at your site
to ensure the water supply pressure
is always within the unit’s required
operang pressure.
• Contact your local water authority
to conrm whether your proposed
Water Witch supply side installaon
complies with the relevant water
regulaons.
• Individual components may need
to be replaced in the future. All
installaons should incorporate
provisions for easy part replacement.
• The Water Witch includes wearing
components that may fail or be
aected by onsite condions. A
visual inspecon of all components
is required at least every month to
ensure the unit is operang correctly.
•
The power supply must always be
turned o and the Water Witch
power lead removed from the power
supply if the control box cover is
being removed.
Please note the following important project consideraons:

04
PRODUCT COMPONENTS AND PART NUMBERS
The reliability and durability of the Water Witch is founded on its simplicity – there
are just three main components and the unit will work well if all components are
funconing correctly and site condions are suitable.

05
The Control Box is the brain of the operaon. A circuit board within the Control Box
connually receives signals from the Sensor to conrm whether the body of water is at
the required level or if water needs to be added to the project.
CONTROL BOX INSTALLATION
• Posion the mounng bracket at
least 1.2m above ground level and
ensure a consistent power source
is within reach of the Control Box
power lead.
• The Control Box is approved for
indoor and outdoor use. However,
locang the Control Box so it is
protected from the weather will
extend its serviceable life.
• Secure the mounng bracket to the
desired posion on a wall or post
with appropriate screws for the
backing material.
INSTALLATION PROCESS AND CONSIDERATIONS:
• Clip the Control Box into the bracket
where it will be held in place.

06
SENSOR INSTALLATION
The Sensor sits in a balance line, tank or trough to monitor the project’s water level. A ball
oat inside the Sensor lowers as the water level drops, in turn connecng a light beam
between two LED lights in the top of the Sensor. These lights complete an electrical circuit
and the Control Box opens the Solenoid to add water to the project.
As water is added to the project, the water level rises and the ball oat is pushed to
the top of the Sensor. As the ball intersects the light beam at the top of the Sensor,
the Control Box recognises the full water level. Instead of stopping the ow immediately,
the TIME DELAY MODE then overlls the project for a set period as dictated by the
parcular seng.
The Water Witch Sensor is available in standard lengths of 5m, 20m, 30m, 40m, 50m
and 60m. Special order sensors can be manufactured up to 250m long.

INSTALLATION PROCESS AND CONSIDERATIONS:
• Two 50mm class 9 or class 12 PVC pipes are required as balance lines from the project’s
wall to the pump and lter area. One pipe is for the sensor and the second is required
for the ll line back to the pool. ALWAYS USE 50MM PIPE FOR THE SENSOR
HOUSING TO ENABLE ADEQUATE FLOW AROUND THE SENSOR AND FUTURE
SERVICABILITY.
• THESE PIPES MUST BE PLACED AT LEAST 300MM BELOW WATER LEVEL and can
be dressed with push-in eyeballs to match the project’s other wall ngs.
• The pipes are usually run along the sucon and return trench and elbowed up within
the equipment area. THESE PIPES MUST BE LEVEL TO AVOID AIR LOCKS which will
aect ow and performance.
• A 50mm cap is provided to cover the sensor pipe housing and protect the Sensor
from dust, debris, pests and foreign materials. The cap ts neatly onto the 50mm
sensor pipe housing.
• DO NOT GLUE THE CAP TO THE SENSOR HOUSING PIPE.
• If the Sensor is to be located away from the equipment area, ALWAYS RUN THE LEAD
THROUGH ADEQUATELY SIZED CONDUIT THAT WILL ENABLE THE COMPLETE
SENSOR TO BE REPLACED AT A LATER DATE.
• NEVER CUT EXCESS SENSOR CABLE. Roll excess cable and bind together with the
Velcro straps provided.
• INSERT THE SENSOR PLUG
INTO THE CORRECT PORT
ON THE CONTROL BOX AS
INDICATED ON THE LABEL.

08
SOLENOID INSTALLATION
The Solenoid is regulated by the Control Box. When the water level is low the Control
Box sends a 22V DC current to open the Solenoid so water ows in to the project.
The Solenoid will close when the water level is restored to the correct level.
Solenoid cables up to 100m long are available by special order.
INSTALLATION PROCESS AND CONSIDERATIONS:
• The Solenoid ow is one direconal
ENSURE THE SOLENOID
FLOW DIRECTIONAL ARROW
IS POINTED IN THE SAME
DIRECTION AS THE WATER FLOW.
• The Solenoid has a 20mm male
thread on each end. Connect to
PCV or copper couplings and pipe
on the water supply line.

• The solenoid requires an operang pressure range of 29-116 PSI (200-800 kPa).
ENSURE THE ONSITE PRESSURE IS SUITABLE FOR CORRECT OPERATION OF
THE SOLENOID. Install a pressure liming valve on the water supply line if the onsite
pressure is greater than 116 PSI (800 kPa).
•A TAP OR TWO-WAY VALVE MUST BE
PLACED BEFORE THE SOLENOID TO
ENABLE THE WATER SOURCE TO BE
TURNED OFF AT ANY TIME.
• Standard installaon posions the supply line
20mm above the ll balance line without a hard
connecon (An air gap is required to ensure the
water from the project cannot contaminate the
water source). THE FILL FLOW RATE MUST
NOT EXCEED THE RATE THE BALNCE LINE
TRANSFERS WATER INTO THE PROJECT.
• If approved in your local area, the ll line can
be plumbed into the ltraon return line.
If installing in this manner, A BACKFLOW
PREVENTER MUST BE INSTALLED
BETWEEN THE SOLENOID AND THE
WATER SOURCE TAP.
• INSERT THE SOLENOID PLUG
INTO THE CORRECT PORT
ON THE CONTROL BOX AS
INDICATED ON THE LABEL.

The solenoid is a wearing
component with an indenite
operang life. Your project
should include suitable overow
provision in case of possible
solenoid failure.

ALTERNATIVE INSTALLATION OPTIONS
BALANCE TANK
The Water Witch is the most
eecve auto leveller for
balance tank installaons.
Maintaining a minimum
water level in the balance
tank will ensure the pump
and pool equipment is
protected whilst also
allowing for the high water level
uctuaons caused by bather
acvity and excess rainwater.
INSTALLATION CONSIDERATIONS:
• The Sensor should be housed inside 50mm class 9 or class 12 PVC pipe aached to
the wall of the balance tank. Fasten the pipe to the wall with brackets, ensuring there
is enough clearance at the top to aach the Sensor end cap.
• Run the Sensor cable through appropriately-sized conduit to ensure the Sensor can
be accessed for serviceability and replaced if required.
• Small debris capable of aecng sensor performance can build up inside balance
tanks. It is advisable to protect the sensor from small debris by covering it with a
silt sock or stocking. Alternavely, cover the base of the sensor pipe housing with
gauze so debris is blocked while water can sll move freely.
• An overow provision will need to be installed at the maximum water height
inside the balance tank.

INFINITY EDGE TROUGH
An innity edge provides pool projects with addional design exibility and creavity.
However, such designs pose addional challenges to ensure the pool operates
eecvely and equipment is protected.
There are two crucial design factors to consider in relaon to the required water level
within an innity edge trough:
• A minimum water depth must be maintained within the trough to ensure enough
water is available to ll the pool and generate an overow into the trough before the
trough runs dry. Failure to do so will most likely result in severe pump, equipment
and site damage.
• The water level in the trough may increase dramacally during a signicant rainfall
event or heavy bather load. The trough capacity above the minimum water level
must suciently allow for this increase.
INSTALLATION OPTIONS:
• This diagram represents the
recommended installaon
layout. Note that onsite
limitaons may not make
this conguraon possible.
• A second opon is to use
the balance tank layout
on Page 10 for installaon
within an innity edge
trough.

It’s now me to start your Water Witch. Complete the following process to test your unit
and conrm all components are operang correctly:
STEP 1: Ensure the project is lled to the required water level.
STEP 2: Ensure the sensor and solenoid plugs are connected to the correct ports
of the Control Box (Sensor on the le and Solenoid on the right).
STEP 3: Turn the power and water supplies on and ensure the solenoid ow
direconal arrow is poinng in the same direcon as the water ow.
STEP 4: Li the Sensor from the balance line and hold it upside down to simulate
full water level. The ON and SENSE lights should ash in unison every
2-4 seconds.
STEP 5: Turn the Sensor around the right way up to simulate low water level. The
ON light should connue to ash every 2-4 seconds and the FILL light
should be solid. The Solenoid should also open and add water to the project.
STEP 6: Repeat steps 4 & 5 a few mes to conrm the unit turns on and
o correctly.
STEP 7: Aach the sensor end cap to the sensor balance line and hold the sensor
cable while you loosen the cable gland. Slowly lower the Sensor unl the
water ow stops and the ON and SENSE lights ash every 2-4 seconds.
Re-ghten the cable gland to set the sensor level.
THE SENSOR IS NOW SET AT THE CORRECT LEVEL. COMPLETE STEPS 8-10
ON THE FOLLOWING PAGE TO SET THE CORRECT TIME DELAY MODE.

TEST AND TIME DELAY MODES
The Water Witch features four me delay sengs
that control the length of the FILL cycle. The me
delay slightly lls the pool with addional water to
prevent the Water Witch from connually engaging
and disengaging the FILL cycle. The four me delay
sengs are controlled by the posion of dip switches
inside the boom right corner of the Control Box.
STEP 8: TURN THE POWER SUPPLY OFF AND UNPLUG THE
WATER WITCH POWER LEAD.
STEP 9: Remove the Water Witch Control Box cover and set the Dip Switches to
the correct mode as per the table above.
STEP 10: Replace the Water Witch Control Box cover, plug in the power lead and
turn the power on.
THE WATER WITCH IS NOW SET TO THE CORRECT WATER LEVEL AND TIME
DELAY MODE.
Refer to the following table for the appropriate me delay seng for your project:
If you need to test the Water Witch or any of its
components you must always return the unit to
TEST MODE as per the correct dip switch seng.

14
OPERATION OF INDICATOR LIGHTS
Signal lights on the Control Box conrm its operaonal status and illuminate as per the
following three sequences:
• ON and SENSE lights are ashing in unison every 2-4 seconds – The Water Witch is
sensing the water level and believes it is at the correct height.
• ON light is ashing every 2-4 seconds and the FILL light is solid – The Water Witch is in
TEST MODE and is adding water because it believes the water level is low.
.• ON and FILL lights are solid – The Water Witch is in one of the TIME DELAY MODES
and is adding water because it believes the water level is low. BOTH LIGHTS WILL
REMAIN ILLUMINATED DURING THE TIME DELAY FILL SEQUENCE AND WILL
ONLY RETURN TO SENSE MODE AFTER THE ADDITIONAL WATER HAS BEEN
ADDED.
