01/21 FlowTimer+ Set 26
8.2 Checking thetightness
After installation and safe venting, the entire system should be
tested for leaks (test duration approx. 5 minutes).
In normal operation, this test is performed autonomously,
but requires several hours (see also Intended use chapter
3).
To measure the tightness, all water tapping points must be
closed.
Now switch the FlowTimer+ to test mode.
To do this, keep the Set / Reset key (8) pressed (max. 10 sec.)
until the status display flashes green/yellow and the Check
display flashes yellow. The system is now in test mode (see also
chapter 9.1.4).
Observe whether the status display after the green/yellow
Flashing (after max. 5 minutes) then shows green.
If the status display shows green, the system is tight. Please
press the reset key once briefly to return to normal
operation.
Now do the test and simulate a leak (see next chapter 8.3)!
If the status display shows permanent yellow, the
system is not properly sealed!
Make sure that all lines are vented!
Continue with chapter 10.2.2 Status display permanent
yellow.
