INSTALLATION INSTRUCTIONS
The Smart Water SW900 system is very simple to install. However, it is important that the installation
instructions are followed in the specified step by step sequence as illustrated below. This will ensure the
correct function of the product and long term reliable service.
Not following these instructions could cause the system to function incorrectly, or not function at all.
Step 1 – Tank Sender:
Plug the water sensor cable into the Tank Sender connector. The cable should be aligned as shown below
and the water sensor connector should be locked into position by turning the “thumb lock” on the body of
the connector. Take care plugging the water sensor in as damage can occur to the electrical pins. Turn the
connector thumb-lock clockwise until it clicks firmly into the locked position. It is important that the
connector is locked as this provides the required weather/water resistance. The Tank Sender LED will flash
GREEN until it has successfully booted up.
** If the Tank Sender LED flashes RED please refer to the “Fault-Finding” section at the rear of this manual.
Attach the blue antenna onto the Gold SMA connector on top of the Tank Sender. Turn the antenna in a
clockwise direction until it is “finger tight”. Do not over-tighten.
RECOMMENDED PROCEDURE:Prior to installation connect the 12VDC power supply to the DC jack
on the base of the Tank Sender. The Tank Sender should be charged for approximately 3-4 hours to
ensure a maximum charge level of the Lithium-ion battery prior to installation.

Step 2 – Desk Mount and Wall Mount WiFi LCD Keypad:
**go to step 4 if you have purchased a WiFi Gateway
Plug in the USB power adaptor to an AC mains power supply and connect the USB cable to the rear of the
Desk Mount WiFi LCD Keypad. You will hear an audible “beep”, and the LCD will display the Smart Water
logo and then the “Add Device” screen. The status LED on the rear of the LCD Keypad will be flashing
ORANGE.
If you have a Wall Mount WiFi LCD Keypad, connect the power adaptor to an AC mains power source and
carefully plug in the 3-pin JST connector to the white 3-pin connector on the LCD PCB (Printed Circuit
Board). Do not touch the components on the PCB as this could cause damage to the circuitry. Smart Water
strongly recommends that the Wall Mount WiFi LCD Keypad is installed by a certified electrician.
Attach the black hinged antenna onto the Gold SMD antenna connector on the back of the product. Turn
the antenna in a clockwise direction until it is “finger-tight”. Do not over-tighten.
Desk Mount WiFi LCD Keypad
After the LCD Keypad has booted up it will automatically show the ADD DEVICE screen on the display. If this
screen is not shown it can also be accessed manually by pressing the MENU icon on the main screen and
then MENU -> ADD DEVICE
Add Device
Add Device Screen

Step 3 – Connecting the Tank Sender to the LCD Keypad:
The sensor must NOT be in the tank. The sensor should be connected to the Tank Sender, but not in fluid of
any type. If the sensor is submerged, it will NOT connect to the LCD Keypad.
Confirm the LCD Keypad “ADD DEVICE” screen is showing “WAITING…”, then press and hold the blue
circular push button on the base of the Tank Sender as shown below. The LED will illuminate BLUE for two
seconds, followed by two short WHITE flashes. This confirms that the Tank Sender has successfully
connected to LCD Keypad and passed software test criteria.
The LCD Keypad will beep and the message “TANK ADDED”will be displayed on the LCD.
** If the Tank Sender LED flashes RED please refer to the “Fault-Finding” section at the rear of this manual.
If additional Tank Senders need to be connected to the system (your Smart Water system can monitor up
to twelve different Tank Senders) simply repeat the above procedure prior to proceeding to Step 5.
Your Tank Sender is now connected to the system. Do not put the sensor in your tank, please proceed to
Step 5 to continue the installation process.

Page |11
Step 4 – Tank Settings:
Smart Water recommends entering the approximate height of your tank before final installation. Set the
tank height of your water tank through the MENU screen. After touching the MENU icon on the main
screen, go to the SETTINGS -> TANK SETTINGS -> TANK HEIGHT screen.
SETTINGS TANK SETTINGS TANK HEIGHT
The system has a default tank height set to 2.0metres (2.0M). Set your tank height approximately 10%
lower than the actual height of your tank. For example, if your tank height is 2.2M, then set your tank
height to 2.0M. Once your tank fills to its maximum level the system will automatically re-calibrate to the
exact 100% level (maximum tank level) for each individual tank. If the tank height menu is re-visited at a
later stage, the height displayed will be the exact height (100%) that your tank has reached. This figure may
not be the number you originally entered; however, this is normal operation and indicates that the system
is operating at optimum performance. Please note, if the tank height has changed do not change it back to
the original manual setting entered during installation.
To change the tank height manually, touch the up/down icons to customize your settings. Touch and hold
the up/down button for faster setting (scrolling).
DOWN UP
CAUTION: If the tank height is not set correctly the system may not perform accurately. Smart
Water strongly recommends that the tank height be set slightly lower than the actual height of your
tank. This process gives the system the opportunity to automatically calibrate to a precise 100%
level when your tank fills to its maximum level.

Step 5 Tank Sender Installation:
Take the Tank Sender and the Stainless Steel Sensor to your tank and lower the sensor to the bottom.
Please ensure that the sensor is located at the very base of the tank and away from the main water outflow
(draw-off position) on your tank. Any excess cable can be lowered into the tank also (it is not necessary to
“hang” the sensor in the tank).
Stainless Steel Tank Sensor Tank Sender Installed
CAUTION: The sensor is a delicate measurement instrument. Please always take great care in the
handling of the sensor. Dropping or knocking the sensor can damage it and will void the warranty.
The Tank Sender should be positioned on top of the tank with maximum exposure to sunlight. Battery
charging performance will be enhanced if the solar panel is positioned as per the “Solar Panel Set-Up Guide”
at the rear of this manual. Your system is also provided with an AC main powered option. Simply connect
the 12V power supply to the DC jack on the base of the Tank Sender if required for continuous power.
Included with the Smart Water product is a mounting kit consisting of four 10mm x 25mm self-tapping
Stainless Steel screws. These can be used to mount the Tank Sender to the top of your tank. The Tank
Sender does not need to be screwed onto your tank, but Smart Water does recommend this step as part of
a good installation. Glue and other attachment methods can be used as an alternative for fixing the Tank
Sender to the tank. If using glue DO NOT cover up the venting drains around the perimeter of the Tank
Sender base.
RECOMMENDED PROCEDURE: If the sensor cable is required to enter the tank beneath the Tank
Sender, manually bend/shape the cable prior to connecting the sensor cable. If the cable is
bent/shaped once connected to the Tank Sender, the waterproof connector may be damaged.
RECOMMENDED PROCEDURE:When mounting the Tank Sender ensure that the three venting
grooves around the base are positioned to allow water to drain away freely from underneath. If
water accumulates or floods around the black water sensor connector this could cause the Tank
Sender to operate intermittently or possibly fail.

WiFi Gateway Instructions
Once the antenna is fitted connect the
12VDC power pack to mains power and then
connect it to the DC jack on the base of the
WiFi Gateway.
Firstly, connect the antenna to the gold SMA
connector on top of the WiFi Gateway. Turn the
antenna clockwise until it is gently tightened.
The “STATUS” LED should now be
flashing ORANGE in preparation for the
“Blink Up” procedure. Once connected to
WiFi, the WiFi Gateway can be mounted
on a wall, or any convenient position.

ICON DEFINITIONS
Menu
Touch this icon to access the full set of system settings and menus that are available.
System Status
Touch this icon to see the system status and any system notifications or alerts. By touching this icon, you
will be taken into the system status screen. When the status icon is “green” the status of the system is
normal, and the status screen will show the text “Normal Operation”. When it is “red” there is an issue that
the system wants to notify the user about. The status screen will show a list of the problems detected. For
example, an abnormal usage alert could be generated by a leak in your water tank plumbing, a toilet
constantly flushing or simply a tap left on. Other alerts include low Tank Sender battery, low signal strength
and Pump Controller warnings. By pressing the status icon, the alert is cleared, and the icon will return to
green, however the alert will remain in the status screen until the alert condition is rectified.
Days to Empty
56 Days
This icon displays the estimated “time to empty” that is available before your tank supply will run out
(based on your current water usage and rainfall). If for example you were getting low on water and
subsequently became more efficient with your water usage, the estimated “time to empty” would increase.
The maximum “time to empty” is displayed as 100+ days. When Smart Water is first installed the status
button will default to 200+ days once your water usage has been learned and stored into memory by the
system the time to empty will update to a new value.

Page |18
Tank Number
1
The tank number shows which tank is currently displayed on the LCD Keypad. If only one tank is connected
to the system, this number will default to 1. If more than one tank is connected, the tank number icon will
show the number of the tank that is currently displayed. Touch the tank number to allow selection of a
different tank via the device selection matrix. Please note that this function is only applicable if you have
more than one tank connected to the system.
Other tanks can also be selected by touching the tank selection icons (shown above). These allow the user
to scroll left and right through the tanks connected to the system. Please note that this function is only
applicable if you have more than one tank connected to the system.
A maximum of twelve (12) tanks can be connected to a single Smart Water WiFi LCD Keypad or WiFi
Gateway.
Tank Percentage
67%
This percentage figure is an accurate representation of how full your tank is referenced to the maximum
recorded level of 100%. This value will change as the level in your tank rises and falls. The maximum level of
100% will auto-calibrate when your tank reaches it maximum level. Further accuracy can be obtained by
setting the tank outflow height.
Tank Level
A simple “one glance” indication showing the current level of water in your
tank. This indication represents the last reported level of water in the
selected tank (see “tank number” and “tank name”).
The water level in this icon will rise and fall as the level in your tank changes.
Touching the centre of the tank level icon on the screen will take you to the
“History” graph, showing your tank level trend over the past 30 days (see
above).

Page |19
Trend Indicator
A simple “one glance” indication showing if the level of water in the tank is increasing or decreasing. If the
trend indicator is not displayed, this means that there has been no change in tank level over the last two
tank level reports.
Tank Signal Strength
The tank signal strength indicator displays the signal strength being received by the WiFi LCD Keypad from
the Tank Sender, in the form of a rising “bar graph”. If only one bar is shown (highlighted in red), consider
moving the Tank Sender or WiFi LCD Keypad/WiFi Gateway to a position with better reception.
Alternatively consider fitting an external high-power antenna (a range of antenna options are available
from Smart Water to suit most installation requirements). If two bars only are shown this is still adequate
for reliable operation.
Please contact Smart Water or your local retailer for further installation assistance on maximizing wireless
performance.
Battery Level
Indicates the level of charge in the Tank Sender battery. The battery level will change according to which
Tank Sender is selected on the main screen (if multiple tanks are connected to the system). If the icon
shows only one bar (in red) this indicates that the Li-ion rechargeable battery in the Tank Sender has a low
state of charge, consider plugging in the battery charger to increase the battery charge.
If multiple tanks are connected to the system, touch the battery low icon to display a list of tanks and their
respective battery levels.
