11.1.3 Appliance handover
f Explain the appliance function to users and familiarise them
with its operation.
f Make the user aware of potential dangers, especially the risk
of scalding.
f Make users aware of critical environmental factors and re-
quirements concerning the installation site.
f Inform the user that enabling the "runtime-dependent rapid
heat-up" function results in higher power consumption. The
function should be deactivated during the summer and in
spring/autumn if at all possible to prevent excessive power
consumption. To avoid increased power consumption, only
reduce the factory-set time for runtime-dependent rapid
heat-up if necessary.
f Inform users that water may drip from the safety valve dur-
ing the heat-up process.
f Please note that the appliance is not protected against frost
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
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 before interrup-
tion of the power supply, this is reactivated 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
blocked by additional safety devices (motor overload relay
and high pressure switch). This block should lift after 1
to 10 minutes.
