User Manual
Operation
The electronically regulated continuous-fow water heater with automatic
temperature adjustment keeps the outflow temperature constant.
The device has touch key “ ” to switch it on and off, and / keys to adjust
the heating.
: Decrease the outlet setting temperature;
: Increase the outlet setting temperature.
Adjust the temperature settings as desired.
If the selected outfow temperature is not reached when the tap is fully opened,
then the water fow through the device exceeds the capacity of the device. In
this case, the fow should be reduced with the hot water valve. There is a
danger of scalding at outfow temperatures exceeding 108°F.
Mixer taps and thermostatic mixer taps should be of a design compatible with
devices with flow control.
If used with shower heads, the shower heads must be with a low pressure
loss.
Fittings for open-outlet water heaters should not be used!
Only fttings for close-outlet water heaters can be used!
Suggestion: To ensure that the minimum flow (switch-on flow 0.26GPM) of a
water-pressure operated device is reached.
Without a temperature limiter, high temperatures may be reached at
draw-off points. Keep children away from the draw-off points. Danger of
scalding!
The appliance should be disconnected from the electrical mains supply
when working on the water supply. After service work is complete, proceed as
during the frst-time appliance start-up.

If the water supply is interrupted, e.g. due to maintenance on the mains
water supply, then the following steps should be undertaken before returning
the device to operation:
1. Remove the fuses or isolate the device in another way.
2. Open a hot water valve connected to the device until the air is vented from
both the device and the cold-water supply pipe.
3. Reconnect the supply.
First aid
• Check the leakage protection switch and the fuses.
• Check if any fttings or shower head are affected by the build-up of lime scale
or dirt.
• See also “Troubleshooting by users”.

Problem
Water heater is not
heating at all (water is
fowing but the unit is not
heating - the outgoing
water temperature is the
same as the cold water
supply) - the digital
display does NOT
light up.
No power or incorrect
wiring. Make sure the breakers at main electrical panel
are ON. You may have a
faulty breaker or unit
may be wired incorrectly.
Flow rate is too low Something was blocked
in the filter mat / Pipe
was blocked.
Check and clean the
filter mat inside the inlet
connector.
Water heater is not

display DOES light up,
but no temperature
display.
Flow rate is too low /
water pressure is too
low.
The air bubbles in the
water heater have not
been purged out.
Make sure the breakers
at main electrical panel
are ON, turn on the unit
and open the hot water
tap for about 20s.
Your water heater has
an activation flow rate of
approximately 0.26GPM.
If your water fow rate is
less than this level, your
unit will not activate.
Increase the flow rate or
check the filter mat inside
the inlet connector.

Water heater is heating,
but the water
temperature is not hot
enough.
User temperature
setting too low. Increase the temperature setting on the unit.
Depending on your
incoming water
temperature and the kW
of your heater, your water
flow rate may exceed the
physical heating capacity
of your water heater.
Reduce the flow rate by
installing a Flow
Regulator.
It’s a new installation,
have your electrician
double check the wiring.
It's possible that the
wiring is incorrect.
The heating elements on
your water heater are
design for 240 volts.
When used with a lower
voltage, they produce
less heating power. You
may need to upgrade to
a larger input heater
You do not need to mix
as much cold water with
your tankless water
heater compared to
when you use a
conventional water
heater. You may also
have an anti-scald
feature on your faucet
that is mixing cold water.
These types of faucets
can usually be adjusted
to reduce the amount of
cold water mixed.
Flow rate is too high.
Crossed wires.
Voltage less than 240
volts.
Mixing too much cold
water.
