Rinsing During Domestic Insulation - Rothenberger ROPULS eDM Serie Instrucciones De Uso

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 ad-
justed using a reservoir and a pump.
Minimum volume flow and minimum number of tapping points to be opened for rinsing at a min-
imum 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 distribu-
tion 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.
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 discon-
nect 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 the rinsed
pipe. Then a new leak test is necessary. The final pipe installation must be completed pro-
fessionally.
8. 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.

Rinsing during domestic insulation

1. Set the switch to rinse.
2. Press the ON/OFF
cally.
When filling the compressed air reservoir, do not pull the electrical plug when the com-
pressor is running.
3. Open the water feed.
4. Press the program button "Water + Air (pulsing)"
5. Read the minimum flow speed and compare it to the standards chart (see 6.2, section No.
3).
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.
