Operation
The heater switches on automatically straight after
reaching the flow rate over 2,5 l/min. The tempera-
ture control system selects an appropriate heating
power depending on the rate of flow, temperature
setting (set with the use of a knob on the front case)
and the temperature of water in the mains.
There are two indicators on the case:
- green – power supply “on”,
- red – heating “on”.
If the red indicator starts to flicker when heating is
being switched “on”, it means that the water flow is
too high for the temperature setting (the flow or the
temperature set should be reduced).
If the red indicator flickers, when there is no heating (no flow through the heater), it
means that a failure of the temperature sensor has occurred.
If the red indicator is on for about 1 sec. and off for the next 3 sec., it means that
the heater is blocked by NA entry.
Faults
Repairing the above is not covered by the warranty. If the heater breaks down (and
it is caused by none of the above reasons) you need to contact distributor/seller.
If the following signals of faulty work are noticed, check for possible reasons:
Fault Reason
if the indicators on the case
are off
the plug-in connector is not properly inserted [NAST],
there is a failure of power supplies,
if the heating is weak or it
does not heat at all
there is a failure of power supplies,
if the flow rate is not suf-
ficient
regulating valve has been incorrectly adjusted.
