7.9. Restarting

After long periods of downtime:
• I f this downtime was planned or scheduled, turn
OFF the control unit and close off the lockshield
valves to the system and the isolating valve to the
top-up line. After that decompress and then drain
the water area. We recommend you carry out
maintenance before restarting (see Maintenance
section).
• Use the commissioning records for restarting and
check especially for system changes that can lead
to other operating conditions of the expansion
automat (e.g. system pressure).
If the power supply has failed:
• T he target parameters and default settings
for pressure, aeration and top-up will remain

unchanged, meaning automatic operation will
resume automatically when power is restored
(control unit ON). Extraordinary system operat-
ing conditions (e.g. cooling to below the default
setting) may fall outside the permitted settings of
the expansion vessel.
Caution: please ensure that when the system
cools down or warms up, the minimum or max-
imum system pressure does not exceed or fall
below the permitted operating pressure. Under-
and over-pressure safety for operation of heating
or cooling systems are not within the standard
scope of supply of the Wilo-Sinum.
Check the automat's operation once power
supply has been restored and, if necessary, set
the actual date and time values (overview menu
options).
