The tightness check acc. to DIN EN 806-4 at drinking
water pipes is registered as a control pragram in the

menu "Drinking water / Drinking water plant dry"
to the menu point „Tightness check dry". Activate
the menu point with <Enter>.
2. Check if necessary the values of stabilisation time,
measurement time and test pressure with <F1>
(back with <ESC>).
3. Lock the gas pipe with a suitable adapter (test
stopple, high pressure stopple or one-pipe counter
cap).
4. Connect the components as described in
chapter 3.
5. Start the control program with <Enter> (the pump

sure).
6. Wait for stabilisation time (if the pressure remains
in the range „test pressure +/- 10%" during stabilisa-
tion time, so the measurement time will start). If nec-
