easyflush
installation guide
1
Introduction the easyflush valve provides electronic flushing and filling of the WC.
There are two versions to suit different applications: easyflush wave is operated by the user bringing their hand towards the infrared sensor. The dual flush is standard.
A part flush is triggered by a quick hand pass (under 1 second) and a full flush is triggered by a slightly longer hand pass (over 1 second).
easyflush walkaway is activated when the user stands up or leaves the cubicle, but it can also be activated by the user bringing their hand toward the sensor; this function can be disabled by the installer. The dual flush is standard. A part flush is triggered by short user occupancy (under 45 seconds) and a full flush by long user occupancy (over 45 seconds).

NOTE:
For chemical water treatment.
If the water system has been treated with chemical dosing, ensure the system is thoroughly flushed before fitting any
Cistermiser products. Concentrated chemicals in dead legs can damage the product and result in failure. If the water is treated with Chlorine Dioxide (ClO2), ensure concentration levels are maintained below 5ppm.

Power connections
NOTE:
Only one power source should be connected at any time, either mains or batteries.
It is not possible to connect both simultaneously.
If using the battery case, open it and fit 4 Alkaline
AA (LR-6) batteries as indicated. Reseal and fasten into place on panel using screws (22) or with the sticky pads (24). If used in an exposed installation the battery case can be hung inside the cistern by hooking it over the edge.
If using the mains adaptor, fasten into place on panel in a dry location using screws (22) or with the sticky pads (24) and connect the unterminated mains cable to a 50Hz 230V AC single phase supply via a 1A fused spur (not supplied).
electrical connection
As shown below, connect the spade connectors from the sensor unit to the solenoid prongs taking care to connect the wires according to the colour coding on the label. If these are not long enough they can be extended up to 1 metre.
Connect the power connector from the sensor to the mains adaptor, or in the case of a battery powered installation, the battery case.
NOTE:
Remove the lens protection label from the sensor BEFORE connecting to the power.
When the power is first connected the LED in the sensor flashes amber. This is normal and lasts only a few seconds.
Colour conventions are brown for positive and grey for negative.

Testing and commissioning
Restore the water supply and check all joints and connections for leaks. The cistern will begin filling until the float rises sufficiently to close the water inlet valve.
Check the water level to ensure the cistern fills to the required full flush volume – typically six litres is sufficient – adjust the position of the float if necessary to allow more or less water in for a full flush.
testing operation refill duration setting
It may be necessary for it to be increased or decreased depending on the supply water pressure. The refill duration should be matched to the time it takes the cistern to complete its refill.
Follow the Advanced Configuration instructions in section 9.
NOTE:
During installation it is not uncommon for an unexpected flush to occur as a result of a sensor being unintentionally activated during the refill time delay. To check that operation is correct it is important to take the refill time into account.
the system
When installing the easyflush for the first time air may be trapped in the valve and supply line.
This will cause the valve to fluctuate repeatedly between the open and closed positions. To expel air from the system activate the valve by placing a hand in front of the sensor whilst the valve is in this repeating cycle. It may be necessary to do this several times before the action ceases and the valve operates normally.
wave version:
Test the installation by placing a hand within 10cm of the sensor for 1 second.
The easyflush should enter a part flush, lasting
2 seconds (configurable, see section 9 Advanced setting guide). Place a hand within 10cm of the sensor for more than 2 seconds to activate a full flush, lasting 8 seconds. After operating, the easyflush will not flush again until the cistern is full, but the easyflush does ‘remember’ attempts to flush. This is called a memory flush.
walkaway version:
Same as above to operate wave or sit on WC for 6 seconds to activate a part flush, lasting 2 seconds and for more than 45 seconds to activate a full flush, lasting 8 seconds.
explanation of the memory flush
(rapid green flashing)
If a second flush is requested whilst the cistern is refilling, the easyflush will not flush immediately but will ‘remember’ the request. The sensor will show a rapid green flashing during this time. After the refill duration (see below) the easyflush will flush, completing either a part or full flush as requested.
additional configuration
Additional configuration is possible with an Infrared
Configuration Unit (ICU) remote control.
(Not supplied; contact Cistermiser). See section 10 for further details.
NOTE:
For grey water/rain water harvesting.
Ensure adequate filtering is fitted, a 10µm filter is recommended.
NOTE:
For chemical water treatment.
If the water system has been treated with chemical dosing, ensure the system is thoroughly flushed before fitting any
Cistermiser products. Concentrated chemicals in dead legs can damage the product and result in failure. If the water is treated with
Chlorine Dioxide (ClO2), ensure concentration levels are maintained below 5ppm.

Maximum working pressure:
0.5 bar dynamic

NOTE:
The easyflush is a flush and fill type valve. It uses the incoming water pressure to lift the flush mechanism. At pressures below 0.5 bar dynamic, the valve will not perform as intended.
