2. Valve Operation
3. Valve Installation
EasyflushEVO is a siphonic flushing valve. When a flush is activated the spill over level is lowered below the
water line initiating a siphon and flushing the cistern.
Before commencing installation, isolate mains power supply and water supply.
Idle position
Fit Cistern (Cistern supplied with
EVO CISTERN only). Ensure
cistern is mounted level.
Flush position
Install Outlet fitting into Cistern.
Fit EasyFlushEVO Flush Valve
to Outlet in cistern. Secure by
rotating clockwise.
water level: 6 litre
The flush is activated by the IR Sensor unit. This can be configured to flush on a wave (default) or flush
when the user walks away:
Wave (default):
Walk Away:
To Flush
1 sec Wave = Half Flush
2 sec Wave = Full Flush
Auto Flush
Presence <45 sec = Half Flush
✗
✗
✔
✔
Presence >45 sec = Full Flush
Memory Flush:
If a flush is activated while the cistern is refilling, the sensor will remember the flush request and only
activate when the cistern is full (to set refill time see page 12).
This is indicated by three rising green LEDs.
WARNING:
Cistern must be level!

4. EasyflushEVO Valve Set up
5. Sensor Positioning
Ensure the fill valve is adjusted so the water shuts off at the indicated water level on the flush valve. This is
your full flush volume.
EasyflushEVO can be operated by Wave activation (default) or Walkaway activation. The installed position of
the sensor will depend on your flush activation setting (see below).
The height of the EasyflushEVO flush valve water level and the filling valve float level must be at the
same height.
Wave activation is the default setting and the WC will flush when the user’s hand is placed in front of the sensor.
Alternatively, with the Walkaway activation setting, the WC will automatically flush when the user leaves the cubicle.
See Config in section 12 to change the sensor activation from Wave to Walkaway.
To adjust EasyflushEVO Fill Valve rotate

7. Testing and Commissioning
8. Maintenance
Ensure flush valve and fill valve are set to the same height level (see page 6) so the water level is at the
mark on the Flush valve.
Fill valve (supplied with EVO CISTERN only): Periodically rinse the inlet filter and valve diaphragm. If the
diaphragm is damaged contact Cistermiser for a replacement.
Ensure cistern is level and check for leaks.
You may rinse the filter or the membrane to maintain your fill valve.
Activate flush via sensor or manual override to verify operation.
If the membrane is damaged, you need to replace it.
Lift override lever to
activate flush
Ensure lever is returned
to lower reset position

Refer to section 7 Testing and Commissioning for normal
sensor function indicators after user activation
WC flushes when in use
Working as normal otherwise
No water is entering the cistern
No obvious indicator
Ensure that the water supply is connected and the fill valve is operating
correctly. Check filters for blockages.
The sensor is covered
Anti-vandal mode has been triggered. The object/debris needs to be
removed from the sensor and the valve will resume normal functionality.
Flush valve not activating
The sensor light does
not flash when a hand is
placed in front of it.
Sensor is flashing single
top red LED slowly, or
not at all when a hand is
placed in front of it.
Ensure the power supply is connected. If mains power is being used
through the mains adaptor check that the mains adaptor is working
by reverting to the battery pack. Remove the mains adaptor when
using batteries.
Low or no battery power; change batteries. If operated by mains
power, check wiring then contact Cistermiser.
Ensure that the sensor is mounted in the correct position. Refer to the
Sensor positioning (section 5).
Ensure the sensor range is correctly configured. Refer to the
advanced setting guide (section 11).
Other issues
Sensor flashing red middle
LED 4 times per second
Sensor uncalibrated. Call Cistermiser for advise.
Sensor flashing single red
top LEDs
Low or no battery power. Change batteries. If operated by mains
power, check wiring then contact Cistermiser.
Sensor flashing triple red
LEDs
Sensor covered or heavily scratched. Uncover or polish out
scratches.
Sensor flashing double red
top LEDs
Servo motor obstruction or wiring fault - Call Cistermiser for advice.
Check fill valve and flush valve are aligned with water level
Sensor LEDs OK
Ensure cistern is level
Check manual activation lever is down (neutral position)
Flush volume is too low
Ensure full flush time is correct (default 3 seconds), so all water is flushed
from the cistern. Refer to EasyflushEVO Valve set up (section 4).
Adjust flush valve and fill valve height to change full flush volume.
Continuous flow into the pan from the cistern
No obvious indicator
Water flowing through the overflow; ensure that the water entering the
cistern is being shut off by adjusting the float accordingly. If the float
is set too high, water will continuously flow into the cistern and out of
the overflow.
