ELECTRICAL INSTALLATION
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.
If the power cable is damaged it must
be replaced by the manufacturer, its
authorised service agent or another
qualified person, in order to prevent
a hazard.
The water heater is supplied with a power cable with
earthed plug for 1 phase installation (1 kW). 1 phase in-
stallation provides the best service life for the immersion
heater.
The lowest point of the power cable should be below
the power socket when you connect the water heater
to the socket. This prevents any drops of water from
being led into the socket.
If 3 kW is required, the water heater must be connected
as a permanent installation (2x400V). For permanent in-
stallation, the water heater is preceded by an isolator
(preferably with a signal lamp) with at least 3 mm
breaker gap. The existing power cable can be used if
the plug is cut off.

(FD1 )
Immersion heater (EB1 )
Setting thermostat
For best operating conditions, we recommend a setting
of 60 °C (max approx. 80 °C).
DEALING WITH MALFUNCTIONS
Check the installation's fuses as well as the thermostat
and mixer valve settings.
Wait a few hours without hot water usage and then
check whether the temperature level has risen. If there
is still no hot water, contact the installation engineer.
Resetting the temperature limiter
If the temperature limiter (FD1) tripped, the water
heater must cool for at least one hour before it can be
reset.
• Turn off the power to the water heater
• Remove the plastic cover (QQ3).
• Press the button on the temperature limiter lightly,
max 15 N (approx. 1.5 kg).
Reconnecting sensors
If the immersion heater has been replaced, the sensors
for the thermostat and temperature limiter must be re-
installed in the order shown in the image.
Service
NOTE
Servicing should only be carried out by persons
with the necessary expertise.
When replacing components on Eminent only
replacement parts from NIBE may be used.
