Operating Procedure

General
Pump Function
The pump has a built-in float switch which starts the pump automatically when the greywater level rises to a preset level and stops the pump when the level falls below a set level.

Manual H2grO
The greywater in the manual H2grO is redirected to waste (sewer) or to the garden by a ball valve. The operator must remove the lid and turn the valve handle as displayed on the valve handle.

Automatic H2grO
Controller Switch Functions
The up or down button controls two functions.
They control the position of the cursor ">" on the display screen (when visible) or adjust selected number valves up or down.
Push either button once to move the cursor to the next line or the number to the next value.
The "MENU" button scrolls through the various display screens programmed into the controller. Press once to change the display to the next screen display.

Manual Mode
Check the screen display and ensure the valve is diverted to the garden. If not, divert to garden by pressing the "OK" button.
Press the "MENU" button until the screen (figure 1) displays. You have the option to redirect greywater to either of the four garden outlets.
The cursor ">" will point to one of the garden outlets. Press the "OK" button to accept the marked garden outlet or press the down button until the cursor ">" aligns with the desired garden then press the "OK" button.
The valve will move to redirect greywater (unless the valve is already aligned with this outlet) to the selected outlet and the controller screen will typically display as figure 2.
N.B. The actual garden number will vary depending on the outlet number set by the operator.
In figure 2 the cursor ">" points to "GO TO WASTE" so that the operator can quickly redirect the valve to the sewer by pressing the "OK" button. Press the "OK" button to return to the screen as in figure 2.
In figure 2 the other option given to the operator is on the bottom line where the controller can be switched to "AUTO" mode. Press the down button until the cursor points to "GO TO AUTO", then press the "OK" button and the "AUTO" screen (similar to figure 4) will display.
To change back to manual mode press the "MENU" button and the screen (figure 1) will display. Press the down button until the cursor points to the desired garden outlet number, then press the "OK" button.
N.B. Once the controller is set to a selected outlet (in manual mode) greywater will only be directed to this outlet until this setting is reprogrammed.

Auto Mode
Press the "MENU" button until the screen (figure 4 or 2) displays. If figure 2 displays, press the down button until the cursor aligns with the "GO TO AUTO" and press the "OK" button. The screen (figure 4) should display. Once the display (figure 4) appears, press the "MENU" button until the screen display (figure 3) appears.
You have the option to redirect greywater to any of the four garden outlets.
Based on your specific subsurface irrigation installation you can programme the quantity of greywater to be pumped to each outlet.
A "0 LITRES" setting means no greywater will be directed to this outlet in case an
outlet is not connected. The maximum value can be set to an outlet is "980 LITRES".
Press the "OK" button to activate ">060 LITRES TO G1" then press the up or down button and the quantity will vary in 20 litre amounts until the desired quantity is displayed. Press the "OK" button to accept the quantity on screen and the cursor ">" will move to the line (000 LITRES TO G2). Press the "OK" button to adjust the quantity to G2 and repeat until all the outlets are programmed. Press the "OK" button if there is a flashing square next to the cursor ">" to accept the final entry.
Press the "MENU" button once complete and the screen in figure 6 will display. Press the "MENU" button again and the valve will move to garden outlet 1 (unless the valve is already aligned with outlet 1) and the controller screen will typically display as in figure 4.
While configured to operate automatically the controller screen will typically display "AUTO TO GARDEN 1".
N.B. The down button will not change the valve if "000 LITRES" is displayed.
N.B. The actual garden number will vary depending on which garden outlet is currently open.
N.B. In "AUTO" mode the cycle will progress from garden outlet 1 through to 4 (after diverting the set amount of litres to each outlet) then start again from 1 continuing indefinitely as a cycle.
N.B. In "AUTO" mode do not divert greywater to an outlet which is blocked or blanked off as this will cause permanent damage to the pump.
In figure 4 and 5 the middle line on the display shows a graph of what percentage of the total amount of greywater (programmed to the outlet) has been redirected to the garden outlet. White squareas appear and move from 0% on the left (as shown in figure 4) to 100% on the far right of the screen.
When the pump is operating a "P" will flash on the right hand side of the white squares.
When the white squares fill the line (100%) the valve will move to the next garden outlet automatically and the bar graph will start at 0% again.
In figure 4 and 5 the bottom line of the display shows the cursor ">" pointing to "GO TO WASTE" so that the operator can quickly redirect the valve to the waste (sewer) by pressing the "OK" button. Press the "OK" button again to redirect the valve back to the garden.

Data Recording
The controller also records the amount of greywater sent to each outlet in a day and resets to zero at midnight.
To access this information, press the "MENU" button until the screen (figure 6) displays.
N.B. The default setting for a day is from midnight to midnight Eastern Australian Time. If required, specialist technicians can adjust the controller to suit specific time zones.
