FLOW TIME ADJUSTMENT
adJustment leVels
the flow time is programmable on site. If necessary, the default flow time of 2 minutes
can be adjusted to any value between 5 to 2600 seconds. the adjustment mechanism is
composed of 3 adjustment levels for changing the flow time. an indicator light (led) will
guide you from one level to the other.
the following table shows the number of steps in each level, the duration in each step
and how to recognize the adjusting level you are in.

24 hs antI-legIonella / antI freeze dutY flush cYcle optIon
this anti-legionella / anti freeze feature provides an automatic duty flush cycle for
30 seconds if the shower has not been used in the previous 24 hours.
this feature is optional and is ideal for buildings such as schools where the shower
installations are often vacant for long periods. the duty flush cycle maximizes hy-
giene, and prevents frozen pipes during the cold winter months.
In order to activate this option proceed as follows:
1) disconnect the power supply (batteries or transformer).
2) Wait ten seconds.
3) reconnect the power supply.
4) the indicator light (led) on the back of the piezo button will start blinking. after a
few blinks the led will give a steady red light. touch the designated area at the piezo
button when the steady red light is still on to enter into adjusting mode.
note: If you will not press the indicated area, the previous settings will remain.
5) to enable the automatic duty flush option you need to reach adjustment level 4
directly (please see the adjustment levels table at page 23).
once you have entered into the adjusting mode, wait until the led blinks 2 times,
then 3 times and 4 times. Immediately after the led blinks 4 times touch the piezo
button once. this will enable the hygiene flush option. to exit the adjusting mode
wait until the led blinks 5 times. now this option is activated. If the shower will not
be used for 24 hours, a single 30 seconds hygiene flush will take place.
WarnIng! a safe hot water temperature control is needed
this anti-legionella / anti freeze feature is automatic and is intended to be used
with cold or premixed water only. a thermostatic mixing valve (tmV) must be used to
provide safe hot water temperatures and prevent scalding.
