Commissioning

The inverter power feed is usually located at a central distribution
point (e.g. in the main fuse box).

10.5 Assembling the appliance

Note
Refit the appliance cover after completing your work. See
chapter "Maintenance and cleaning / Fitting the appliance
cover").
11. Commissioning
WARNING Electrocution
Never operate the appliance when the casing is open or
without a cover.

11.1 Initial start-up

Note
Fill the DHW cylinder before switching on the power sup-
ply to the appliance.
The appliance is equipped with boil-dry protection to
prevent operation with an empty DHW cylinder.
Note
Following an interruption of the power supply, the
compressor operation remains blocked for at least one
minute. The PCB delays electronic starting by a minute,
during which the appliance goes through its initialising
process. If the compressor subsequently fails to start, it
may be locked out by additional safety devices (motor
overload relay or high pressure switch). This block should
lift after 1 to 10 minutes.
11.1.1 Filling the DHW cylinder
Fill the DHW cylinder and vent the pipework by following the
procedure below:
f Close the drain valve. f
f Open all DHW draw-off points and the shut-off valve in the f
cold water supply.
f Close the DHW draw-off points as soon as water starts to f
emerge from them.
f Check the safety valve by leaving it open until water runs out. f
11.1.2 Settings / function check
f Switch the power supply ON. f
f Check the appliance function. f
f Check the function of the safety assembly. f
Following function check completion, reduce the set DHW temper-
ature for more energy-conscious appliance operation.
f Establish the customer's comfort requirements and adjust f
the set DHW temperature accordingly. For hygiene reasons,
never set the DHW temperature below 50 °C.

11.1.3 Appliance handover

f Explain the appliance function to users and familiarise them f
with its operation.
f Make the user aware of potential dangers, especially the risk f
of scalding.
f Make users aware of critical environmental factors and re- f
quirements concerning the installation site.
f Inform users that water may drip from the safety valve dur- f
ing the heat-up process.
f Please note that the appliance is not protected against frost f
and corrosion when it is disconnected from the power sup-
ply. If voltage is supplied to the impressed current anode and
the PCB separately, the appliance remains protected against
corrosion.
f Hand over these operating and installation instructions to f
users for safekeeping.

11.2 Recommissioning

If the appliance is switched off due to an interruption to the power
supply, no specific measures for restarting are required once the
power supply has been restored. The appliance has saved the
parameters most recently set and continues operating with these.
If the "rapid/comfort heating" function was active prior to power
supply interruption, this is re-enabled with a set temperature of
65 °C once the power supply has been restored.
Emergency mode is not reactivated after an interruption of the
power supply.
Note
Following an interruption of the power supply, the
compressor operation remains blocked for at least one
minute. The PCB delays electronic starting by a minute,
during which the appliance goes through its initialising
process.
If the compressor subsequently fails to start, it may be
locked out by additional safety devices (motor overload
relay or high pressure switch). This block should lift after
1 to 10 minutes.
