Installation of 6 kW immersion heater
Output selector (6 kW)
Set the water heater's output selector to the desired
output. Because the immersion heater receives the
lowest surface output at 3 kW, this position should be
used first. When a higher output is required, for example
during economy rates, set the output selector to 6 kW.

Setting thermostat
For the optimum operating conditions and to prevent
bacterial growth, we recommend a setting of 60 °C
(230V 1-phase and 400V 2-phase max approx. 75 °C and
400V 3-phase 6kW max approx. 85 °C).
Approx. 60 °C
DEALING WITH MALFUNCTIONS
NOTE
Electrical installation and service must be car-
ried out under the supervision of a qualified
electrician, and in accordance with applicable
electrical safety regulations.
Check the installation's fuses as well as the thermostat
and mixer valve settings.

RESETTING THE TEMPERATURE LIMITER
If the temperature limiter (FQ10) tripped, the water
heater must cool for at least one hour before it can be
reset.
• Remove the plastic cover (QQ3).
• Give the button on the temperature limiter a light
press, max. 15 N (approx. 1,5 kg), applies in the event
of 2-phase installation, or max. 40 N (approx. 4 kg),
applies in the event of 3-phase installation.
