Special Instructions For Rinsing Tap Water Pipes - Rothenberger ROPULS 1000000145 Instrucciones De Uso

6. The maximum rinsing line length must not exceed 100 m.
7. To protect sensitive fittings; a pressure regulator must always be installed ahead of the ROPULS.
8. All installed water lines should be checked for leaks.
9. After each use: Completely empty the hoses and the rinse compressor. Prevent water from
remaining in the hoses and rinse compressor. Store everything in a dry place.

4.2 Special instructions for rinsing tap water pipes

According to DIN 1988-2 / EN 806-4 all newly installed tap water pipes must be rinsed before first
use, and the results of this rinse are improved by a mixture of water and pulsating air.
This rinse compressor must be designed with an internal diameter of 2" for pipe cleaning.
For decontaminating systems contaminated with legionella, cleaning with a pulsating air/water
mixture is recommended before the disinfection.
Before connecting the tap water system, make sure that the rinse compressor and all accessory
components (such as hoses, pressure regulators, etc.) are completely sanitary.
The following points must always be observed when rinsing according to DIN 1988 Part 2:
1. The construction manager or the designer should be present during rinsing. After rinsing is
complete, an appropriate rinsing log should be made out.
2. The tap water used for rinsing must be filtered (according to DIN 1988 / DIN 50930).
3. The rinse water must maintain a minimum flow speed of 0.5 m/s in the largest pipe. To reach
this flow speed, a minimum number of DN 15 tapping points must be opened (see chart). If
the volume flow (the required flow speed) is not reached, the speed must be adjusted using a
reservoir and a pump.
Minimum volume flow and minimum number of tapping points to be opened for rinsing at a
minimum flow speed of 0.5 m/s.
Max. nominal diameter of
distribution pipe DN
Min. volume flow with full
distribution pipes Q at l/min
Min. no. of taps DN 15 to
be opened
4. Cold and hot water pipes must be rinsed separately. Pipe systems are rinsed in sections. As a
rule, each rising pipe is considered a rinsing section. The line length per rinsing section should
not exceed 100 m. Begin with the rising pipe that is closest to the rinse compressor.
If an individual rising line is too small to guarantee the minimum volume flow in the
distribution pipe, several lines must be combined into one rinsing section.
5. In each rinsing section, the tapping points are opened level by level, from bottom to top. For
each level, the tapping point that is the farthest from the rising pipe is opened first.
Then open all the others in the same sequence, from bottom to top, and from the farthest
from the rising line to the nearest (see chart).
6. The rinsing time per metre of running pipe must not exceed 15 seconds. Furthermore, each
tapping point must be rinsed for 2 minutes. Once the last tapping point opened has reached
the required rinsing time, close the tapping points in the opposite sequence from which they
were opened.
7. After the rinse, the water supply and the rinse compressor must be turned off.
Then disconnect the device from the power supply. Attention! The rinse compressor must not
be in the process of filling the container. The rinse compressor must be disconnected from
