minutes.
When the stop valve opens again after 3
minutes, the device veries whether water
continues to ow.
If the ow of water exceeds 250 ml, a leakage
problem is suspected → Message A8 is
displayed.
The 48 hours anti-leakage system is deactivated
in the standard setting.
6.2 Activating /deactivating
the 48 h-anti-leakage system
When the time-based leakage protection is
activated, the time set for the standard leakage
supervision is deactivated and replaced by this
time-based protection.
The set volume is not taken into consideration.
Example: When selecting the 600 liters setting,
a leakage problem would be suspected after 3
hours, even if the 600 liters volume has not been
reached.
However, if the time-based leakage supervision
is set to 8 hours, a leakage problem is only
suspected after 8 hours.
In this case, the maximum ow rate shall not
exceed 75 l (600 liters / 8 hours = 75 liters / h) →
Message A9 is displayed.
