Easyflush WC Flush Control Valve
The Easyflush (EF) no touch dual flush WC cistern valve is a
replacement of the previous Easyflush Flush & Fill products
(EF1C, EF2C, EF1E, EF2E and the Capacitance {electric field}
version).
What is the minimum and maximum working pressure?
The Easyflush valve will safely operate between 0.5 and 6 bar
inlet pressure. However the most effective operation flushing is
obtained between 2-4 bar.
Can the lens be repaired if it is vandalised?
Yes, it may be possible to polish out the scratches depending on
the level of damage. Using a very lightly abrasive polishing fluid,
such as Brasso the lens can be brought back to a smooth finish.
How do I know if the sensor activation range is suitable and
how do I adjust it?
In order to find the activation range,move your hand very slowly
towards the sensor lens. When the sensor detects your presence
the WC will flush. If you feel that the range is not correct you
have two options for changing it: either manually or via the
remote control Infrared Configuration Unit (ICU) which comes
with user instructions.
Manual adjustment is as follows: disconnect the power supply
for 5 seconds and reconnect. Tip: make sure that the sensor is
not pointing at any close objects when the power supply is
reconnected.
When the sensor flashes amber place your hand 10cm from the
sensor, (the amber flashing changes to a green flashing) keep
your hand there until the sensor shows a constant green then
remove your hand. The unit has now entered Configuration
Mode. Now when the sensor shows a Single red flashing, place
your hand in front of the sensor. A slow green flashing will be
seen. Move your hand to the distance from the sensor to where
you would like to set the maximum range, please bear in mind
that a light coloured hand is more easily seen than a dark
coloured one. Wait at this position for 8 seconds until the LED
glows a constant green. Move your hand away from the sensor
and wait for all flashing to stop.
How do I know if my refill time is suitable and how do I adjust
it?
To check the refill time. First trigger a full flush by holding your
hand in front of the sensor for less than 1 second. When the valve
has flushed and started to refill, place your hand in front of the
sensor again. The sensor will show a green triple flash
indicating that it has recorded a flush request. If the refill time is
correct, the valve should re-flush once the cistern has completely
refilled. You may wish to change the refill time if either, it
attempts to flush before the cistern is completely refilled, or if
after refilling there is a long wait before you can flush.
If you feel that the refill time is not correct you have two options
for changing it: either manually or via the remote control Infrared
Configuration Unit (ICU) which comes with user instructions.
Manual adjustment is as follows: disconnect the power supply
for 5 seconds and reconnect. Tip: make sure that the sensor is
not pointing at any close objects when the power supply is
reconnected.
How do I know if my run-on time is suitable and how do I
adjust it?
As water will flow whilst a hand is under the spout, a minimal
run-on time is normally sufficient for good operation and will
ensure maximum water savings. However, if it is felt that the runon
time is not correct you have two options for changing it:
either manually or via the remote control Infrared Configuration
Unit (ICU) which comes with user instructions.
Manual adjustment is as follows: disconnect the power supply
for 5 seconds and reconnect. Tip:make sure that the sensor is
not pointing at any close objects when the power supply is
reconnected.
When the sensor flashes amber place your hand 10cm from the
sensor, (the amber flashing changes to a green flashing) keep
your hand there until the sensor shows a constant green. The
unit has now entered Configuration Mode. Now wait until the
sensor shows a double red flashing, and place your hand in
front of the sensor. This will trigger a flush and a green flashing will be seen – remove your hand. Wait until the flush has
completed and the cistern has completely refilled. At this point,
place your hand back in front of the sensor; the refill time will be
set. Step away from the sensor and wait for all flashing to stop.
How do I know if my part flush time is suitable and how do I
adjust it?
In general, to ensure maximum water savings, the part flush
should deliver half the volume of the full flush or less if possible.
If you feel that the part flush time is not correct you have two
options for changing it: either manually or via the remote control
Infrared Configuration Unit (ICU) which comes with user
instructions.
Manual adjustment is as follows: disconnect the power supply
for 5 seconds and reconnect. Tip:make sure that the sensor is
not pointing at any close objects when the power supply is
reconnected.
When the sensor flashes amber place your hand 10cm from the
sensor, (the amber flashing changes to a green flashing) keep
your hand there until the sensor shows a constant green. The
unit has now entered Configuration Mode. Now wait until the
sensor shows a triple red flashing, and place your hand in front
of the sensor. The WC will start to flush and a green flashing will
be seen. When the water has run for the desired part flush time,
move your hand out of the line of sight of the sensor. The water
will cease to flow, and the flush time will be set. Step away from
the sensor and wait for all flashing to stop.
The valve seems to be leaking, what is wrong?
If the WC flushes normally with interaction with the sensor it is
possible that there is debris preventing the valve from closing
securely. However, if you stand in the sensing area and the
sensor is flashing red slowly or not at all place your hand in front
of the sensor to check if your batteries are dead and need to be
replaced.
What happens if the WC is not used for long period? Will it
not smell?
The Easyflush can be configured to deliver a 12hr hygiene flush
function which triggers a flush every 12hrs of non-use. This
keeps the u-bend replenished in long periods. This requires
activation via the optional ICU remote control or factory setting.
The valve is not working, what is wrong?
If the sensor is flashing red slowly or not at all when you place
your hand in front of the sensor it is likely that your batteries are
dead and need to be replaced. If the sensor shows normal
operation (one flash every 3 seconds when you stand in the
sensing area) there may be something wrong with the valve or
your water supply. Ensure that all stop cocks are on and that you
have good pressure at the valve.
If the sensor shows normal operation but you are experiencing a
shuddering noise from the valve, there is air in the system. Flush
the valve repeatedly in the normal way to purge the system.
Other Alarms
Constant red flashing: faulty wiring or solenoid coil.
Red flash twice every 3 seconds: sensor covered or heavily
scratched.
