SET UP PROCEDURE
CISTERN FLUSHING SYSTEM
The next step is programming the ES50. In cistern mode, (the most popular in UK) the set up process
involves timing how long it takes to fill your urinal flushing cistern with water, because every site will be
different due to cistern size and water pressure differences.
Firstly remove the ES50 from its packaging, and carefully lift the rubber gasket (D) over the 3 metal valve
connectors, to reveal the battery tray (IMPORTANT ensure cistern is empty before commencing with
cistern fill time settings). Carefully fit the battery (B) observing the correct battery polarity and replace
the rubber gasket, then immediately (within 20 seconds) fit the ES50 (A) to the solenoid valve head (H).
Attach the M3 securing screw (I) and lightly tighten. Replace the screw cover (J).
You will notice if the battery has been fitted correctly a letter “C” will be displayed on the front of the ES50 which
means it is ready to be set up for use with a cistern fed urinal.
Ensuring your cistern is still empty and the letter “C” is being displayed on the front of the ES50, press the “F”
button so the screen displays “F-S”, meaning the system is ready to start filling. Press “F” again which will then
open the valve and water will flow into the cistern, (while the cistern is filling a small dot will flash on the front of
the ES50 to indicate the cistern fill time is being recorded). Once the cistern has filled, the flush will start at which
point you simply press the “F” button again to record the total cistern fill time. The fill time is now set into the
ES50’s memory.
ADJUSTING THE FLUSH CYCLE (CISTERN FLUSH SYSTEM)
The ES50 will now display “ T - 0 - 0”. As an example, T - 0 - 4 would mean 4 flushes per day, attained by pressing the
“T” button 4 times. T - 1 - 2 would mean 12 flushes per day.
After you have selected the desired amount of flushes wait 20 seconds and the display will extinguish after a “beep”
and this confirms the setting has been accepted. Your ES50 is now set up and will flush your urinals to the desired
rate per day until the battery expires, in approximately 2 years OR when ‘battery low’ alarm sounds.
If you fail to set-up the ES50 correctly, a factory default setting will be automatically selected
(6 minutes fill time, 4 flushes per day).
DIRECT FLUSHING SYSTEM
If you wish to set the ES50 for use with a Direct Flush System hold any button down while connecting the battery
and it will display a letter “D” now you have selected the Direct Flushing mode, you are ready to set up the ES50.
Ensuring the letter “D” is being displayed on the front of the ES50 press the “F” button so the screen displays “F-
S”, meaning the system is ready to start filling. Press “F” again which will then open the valve and water will flow
into the cistern. Press the “F” button again which will then open the valve and start to flush the urinal,( while the
urinal is flushing with water a small dot will flash on the front of the ES50 to indicate the timing is in progress) after about 5-10 seconds
you simply press the “F” button again to record the total urinal flush time.
Important In Direct mode “D” it is only normally recommended to flush a urinal for about 5 – 10 seconds duration.
For Direct Flushing Systems you will require a larger orifice valve (ES50.6) (please seek advise from the manufacturer).
ADJUSTING THE FLUSH CYCLE (DIRECT FLUSH SYSTEM)
The ES50 will now display “ T - 0 - 0” (where T12 would mean 12 flushes per day) and this is attained by pressing the “T” button 12
times, after you have selected the desired amount of flushes wait 20 seconds and the display will extinguish after a “beep” and this
confirms the setting has been accepted.
Important; In Direct mode “D” it is only normally recommended to flush a urinal with more frequency than with a cistern due to the
lower flush volumes.
If you fail to set-up the ES50 correctly, a factory default setting will be automatically selected (12 x 5 second flushes per day).
CARE AND MAINTENANCE
* Only fit and use prime quality batteries such as ‘Energizer’ or ‘Duracell’
* Replace the battery every 2 years OR when ‘battery low alarm’ sounds, to ensure the product functions correctly.
* Ensure the device is always kept clean and and away from the elements, as the ES50 is not designed for exterior applications.
* To check the current cistern FLUSH TIMING frequency press “T”
* For the number of FLUSHES since installation press “F”
* To RESET remove the battery and leave for approx. 10 minutes for current to drain and memory to reset or you can remove the
battery and place your fingers across the contacts whilst holding one of the buttons down for approx. 10 seconds to drain the
current.
* If a TEST FLUSH is required press and keep holding “T” then at the same time press and hold the “F”, keep both buttons pressed whilst
the display goes through its software version, once it displays “UER” let go of both buttons and a test flush will be performed after
which the ES50 will revert back to your previous programming.
