Typical Piping Arrangements

Typical Installation with Cistern Feed

Typical Installation with Direct Feed

NOTE: Multiple water outlets may require a form of water balancing to achieve uniform flushing.

Installation

Solenoid (Cistern & Direct Feed)

1. Isolate water supply. An isolating valve must be installed in accordance with AS/NZ 3500.1
2. Identify a suitable position for the solenoid assembly. Position in an upright position (preferably). If cistern, position solenoid as close to cistern as possible.
3. Cut the water supply pipe and flush thoroughly to purge the swarf and debris. Failure to perform this step may cause the solenoid to become blocked and it will not close.
4. Ensure solenoid valve orientation is correct (flow direction is marked on the body of the valve with an arrow).
5. Fix appropriately to the wall or in the ceiling cavity.
6. If direct feed urinal, fit air break at the top of the urinal spurge pipe.
7. Turn the water on and check for leaks.

IMPORTANT:

• If water pressure exceeds 500 or 5 bar, install a flow restrictor valve (not supplied). A flow restrictor valve must be installed between the isolating valve and the solenoid valve.
• If any water hammering is present, install a hammering arrestor (not supplied).
• Continued hammering may cause the solenoid to fail and bounce open.
• If the solenoid is blocked due to debris and cannot close, check and clean the filter.
• If water quality is poor, additional filter protection may be required.
• Cistern – ensure a flush triggering level of the auto siphon is below the water inlet – Fig 1. an air gap must be present between the cistern water level and the water inlet pipe to prevent back-flow – Fig 1.

Sensor (Surface Mounted)

1. The sensor can be ceiling (preferable) or wall-mounted. For optimal performance, sensor should be positioned 1 – 1.5m from the urinal (allow traffic to pass through versus standing under)
2. For single-stall urinal position sensor above the center of stall.
3. For double or triple urinal position in the center of stalls.
4. If more than 3 urinals, use additional sensors.
5. When a suitable location has been found, remove the mounting plate from the sensor unit (magnetic) and fix to the ceiling (or wall) using the appropriate fixing for the substrate. Take note of sensor slot orientation – Fig 3 & Fig 4.

NOTES:

• If mounting on the wall ensure the sensor slot is orientated North / South. It can also be tilted to capture a greater range of heights – Fig 4.
• Avoid locating sensors near heat sources (hot pipes, radiators, heat emitting lights, or where direct sunlight encroaches on the sensor lens).
• Additional flex (cable between sensor and solenoid) can be supplied upon request. DO NOT cut and join as polarity is critical to operation.

IMPORTANT:

• Never connect the battery or power pack directly to the solenoid valve or until all plumbing connections are completed. Power must be connected last.

Connect Solenoid Valve to Sensor

1. Run the latching valve cable to the sensor. Ideally, this will be within the wall, ceiling cavity, or in conduit.
2. Do not extend the cable as this will affect correct operation (we can provide more flex if required).
3. Once the power is connected, the system operates in default factory settings.

Connect Mains Power Supply (optional)

1. Locate the battery holder and battery supplied with the system. If connected, remove the battery.
2. Carefully align the power pack outlet cable plug to the power inlet plug attached to the printed circuit board.
3. Connect the power pack to 220-240V 50/60Hz AC power supply (do not turn on).

Set up

1. Turn the water on and inspect all connections. Start with isolating the valve half open.
2. Separate the two halves of the sensor assembly by removing the 4 x self-tapping screws.
3. Affix the battery pack (or power pack if mains) to the back cover and pass the solenoid lead through the hole.
4. Connect the solenoid lead and battery to the printed circuit board (PCB) – Fig 5.
5. Program flush cycle. See page 9 for further details.
6. Reassemble the controller.
7. Attach to ceiling plate via back plate magnets.

Programming Flush Cycles

Direct Feed Urinals

1. Set the pre-flush to “2” (jumpers hard left) – See page 10.
2. Select time delay before flush. We suggest 1 minute.
3. Select janitor flush time (either 6 or 12 hours).
4. PUSH & RELEASE the learn button to start the flow of water (green LED flash).
5. When sufficient water has flowed to clear the urinal PUSH & RELEASE the learn button again to stop the water flowing (red LED flash).
6. Your flush cycle is now set.
   • IMPORTANT: The flushing volume of water should not exceed the volume the sparge pipe (and urinal) can flush to avoid flooding during faults and/or blockages.

Cistern Feed Urinals
It has been assumed that the cistern will be fitted with an auto siphon.

1. Set the pre-flush to “0” (jumpers hard right) – See page 10.
2. Select a time delay before flush. Options range from 25 sec to 15 min.
3. Select janitor flush time (either 6 or 12 hours).
4. With the cistern empty, PUSH & RELEASE the learn button to start the flow of water (green LED flash).
5. Continue filling until the auto siphon system starts to flush. Count 1001, 1002,1003 then PUSH & RELEASE the learn button again to stop the water flow (red LED flash). The fill cycle should over-run the flush by a few seconds to allow for pressure fluctuations.
6. Your flush cycle is now set.

IMPORTANT:

• You should not have a volume of water entering the cistern greater than the sparge pipe (and urinal) can flush. This is to safeguard against a possible overflow of the cistern under fault conditions.
• With a cistern set up, the sensor will not flash on detection and will flash once the chosen delay period has passed and the solenoid opens.
• The maximum available flush time is 7 minutes.

Advanced Problem Solving

• When the learn button is pushed and released (to open and close the valve) the LED’s at the sensor and the solenoid valve should flash simultaneously.
• If both LEDs flash and you can hear the solenoid trying to shut or click – ensure there is water at the source and the solenoid is clear of debris. If this fails to resolve – replace the solenoid valve.
• If the LED flashes at the sensor, but not the solenoid valve – check the connection and cable between the sensor and solenoid, including polarity. If this fails to resolve – replace the solenoid valve.
• If there is no LED flash at the sensor – ensure there is power, all connections are correct, and no signs of corrosion. If this fails to resolve – replace the printed circuit board (PCB).
