6. Flushing must proceed per train of pipes, i.e. the train closest
to the cleaning compressor is to be flushed first, and so you
continue to the furthest train.
7. All taps are to be opened from the rear towards the front or
closed from the front to the back after the flushing process is
complete.
Example:
Open one after another
Close one after another
8. The flushing process is complete once there are no more particles in evidence. (If flushing to
DIN 1988. part 2, paragraph 11.2 (E), 2 minutes per outlet are sufficient.). We recommend
letting the draining water from the tapping points flow over a mesh of approx. 100 µ.
9. Close the water supply after flushing. Disconnect the cleaning automate from the mains.
NB! Compressor may not fill up. The filling process (8 bar) must be complete. The cleaning
automate must be separated from the test pipe, and all connections must be properly fitted,
after which a leakage test is required.
10. After the flushing process, issue a flushing report (certificate); customer keeps the original
and the copy is for the company doing the job.

3. Push program key 'flushing with disinfectant'.
Flow rate is indicated when stop valves are opened.
4. Open all taps one after another and take chlorine value.
Value must be between 0,6 and 0,8 mg/l. Now close all taps.

6. After a resting period of approx. 4 hours, open taps and let flushing water run via active
carbon filter into the sewage system.
