If the minimum flow speed of 0.5 m/sec. is not reached, rinse by using the storage tank and
pump.
6. The rinsing time per metre of running pipe must not exceed 15 seconds. Furthermore, each
tapping point must be rinsed for 2 minutes.
7. The rinsing process is over when no more discharges are visible. (When rinsing according to
DIN 1988, part 2, paragraph 11.2 (E), 2 minutes per outlet is enough.) For this it is recom-
mended that the water escaping from the tapping points be allowed to flow through a mesh
with a width of about 100 μl.
8. After the rinse, the rinse compressor must be turned off. The compressor must not fill. The
filling process (8 bar) must be completed.
9. Then close the water feed.
10. Then disconnect the ROPULS from the power supply.
11. The rinsing machine must be separated from the test pipe, and all connections must be
properly installed. Then a leak test is necessary.
12. After the rinsing process, a rinsing log (certificate) must be made out. The original copy must
remain with the customer and the carbon copy with the company performing the work.

Disinfecting with ROCLEAN during domestic installation
For disinfection with a ROCLEAN injector, see the ROCLEAN injector operating manual.
6.5
Rinsing with disinfectant during domestic installation
Select the program "Water and disinfectant"
dosing-pump.
Only officially approved disinfectants may be used to rinse the installation. According
to DIN EN 1717, if necessary, a suitable pipe separator or system separator must be
installed ahead of the rinse compressor to the tap water fuse.
1. The ends of the outlet hoses must be connected to activated carbon filters.
2. Connect the dosing pump hose to the "Disinfection" connector.
3. Connect the pulsation output plug on the ROPULS electronics to the electronics of the dos-
ing pump. This will adjust the dosing to the rinse compressor pulse.
4. Press the "ON/OFF"
ically.
5. Press the program button "Water with disinfectant"
When the installed stop valves are opened, the flow rate is displayed.
6. Open the taps on the system to be cleaned and check the disinfectant concentration. Here
also follow the information in DVGW worksheet W 291.
7. After testing the concentration, close the taps again and, in compliance with worksheet W
291, wait until the system has been disinfected.
8. Remove the rinse compressor and reinstall the connections.
9. After an appropriate delay, open the taps again and let the rinse water flow out through an
activated carbon filter into the public sewer or, if necessary, catch it in a supplementary tank.

Rinsing floor-heating systems
1. The water supply must be disconnected from the water heater.
2. According to DIN EN 1717, a suitable pipe separator or system separator must be installed
ahead of the rinse compressor to the tap water fuse.
3. Disconnect or close the return pipe and attach a drain hose. Additionally, the hose must lead
to a drain of sufficient dimensions and be fastened.
4. When water pressure is low, rinse the heating system section by section.
