every disinfection. To do this, fill a clean, sealable container with 100 ml of water
and draw 1 ml of dosing solution from the bottle using the pipette provided with
every carton of ROLLER'S Plus TW-D Color and add it to the container (ratio
1:100). Seal the container and shake well. The concentration of the container
contents is measured with the test strip (Art. No. 091072) according to the
instructions printed on the test strip package. This should be ≥ 150 mg/l H
Open the bottle (21) and pour the enclosed dye (20 ml bottle) into the bottle
immediately before the disinfection process. Close the bottle then shake so
that the dye is mixed evenly with the hydrogen peroxide.
CAUTION
The dye is not harmful to the health but very intensive and is very difficult to
remove from the skin or clothing. Therefore pour the dye into the bottle carefully.
Fit bottle to the disinfection unit ROLLER'S Inject TW as shown in Fig. 7 (21).
The nozzles installed in ROLLER'S Inject TW and ROLLER'S Inject H for
automatic dosing of dosing solution, cleaner and corrosion protection are
different sizes and adapted to the properties of the ingredients to be injected.
Therefore make absolutely sure that ROLLER'S Inject TW is connected for
disinfection of drinking water pipes. Program 3.1.1. Select flush with water
(without air supply). During the filling process, all tapping points on the drinking
water installation must be opened one after another, starting with the furthest
away, until the dyed disinfection solution emerges at the respective tapping
point. If the tapping point is in a dark environment it is helpful to hold a white
background (e.g. a sheet of paper) behind the outlet in order to be able to see
the disinfection solution better.
The supply to the disinfection unit before ROLLER'S Multi-Control and the drain
to the drinking water installation must be shut off at the end of the disinfection
process. Then the bottle (21) must be removed slowly so that excess pressure
can escape.
After 24 hours exposure (recommendation of the German Central Association
for Sanitary, Heating and Air Conditioning (ZVSHK) and recommendation of
the German Association of the Gas and Water Industry (DVGW), the disinfec-
tion solution must be flushed out of the drinking water installation with ROLLER'S
Multi-Control. To do this, all tapping points must be opened again one after
another, starting with the nearest, until there is no longer any trace of the dyed
disinfection solution.
Additionally, peroxide test strips can be used if necessary to check the concen-
tration (accessories, see 1.2. Article numbers).
NOTICE
Hoses used for disinfection/cleaning should no longer be used for pressure
testing with water and for flushing drinking water pipes.
3.3. Testing drinking water installations with compressed air program
WARNING
For Germany the information leaflet "Leak Tests of Drinking Water Installations
with Compressed Air, Inert Gas or Water" (January 2011) of the German Central
Association for Sanitary, Heating and Air Conditioning (ZVSHK) defines the
following for the national regulations under "3.1 General":
"Due to the compressibility of gases, the rules for the prevention of accidents
"Working on Gas Systems" and the "Technical Rules for Gas Installations
DVGW-TRGI" must be observed for physical and safety reasons when
conducting pressure tests with air Therefore, the test pressures have been
defined as maximum 0.3 MPa/3 bar/43.5 psi, the same as for load and leak
tests for gas pipes, in agreement with the responsible industrial liability
insurance association and based on these rules. The national regulations are
thereby fulfilled."
The respective national safety provisions, rules and regulations valid for
the application site must be considered and observed.
Before conducting a test with compressed air, it must be assessed whether the
installation to be tested will withstand the preset / selected test pressure "p
refer".
Section 6. of EN 806-4:2010 defines among other things that: "Installations
inside buildings must be subjected to pressure testing. This can be done either
with water or, if national regulations allow, oil-free, clean air with low pressure
or inert gases may be used. The possible risk from high gas or air pressure in
the system must be considered." However, apart from this note, the standard
EN 806-4:2010 contains no test criteria whatsoever for testing with compressed
air.
The tests described below and the defaults stored in the ROLLER'S Multi-Con-
trol correspond to the information leaflet "Leak tests of drinking water installa-
tions with compressed air, inert gas or water" (January 2011) of the German
Central Association for Sanitary, Heating and Air Conditioning (ZVSHK). Future
changes to this information leaflet or the respective valid provisions, rules and
regulations for the application site must be considered and changed test criteria
(test sequences, pressures and times) must be corrected in the defaults.
The programs can be aborted at any time with the Esc button (10). Then all
the valves open and the pressure in the installation is released. The tests are
saved but "Cancel" is shown in the file.

3.4. Testing drinking water installations with water programs (ROLLER'S
Multi-Control SLW)
Section 6.1 of EN 806-4:2010 offers 3 test methods A, B, C for hydrostatic
pressure testing depending on the material and size of the installed pipes. The
test methods differ in different test sequences, pressures and times.
For Germany, the information leaflet "Leak Tests of Drinking Water Installations
with Compressed Air, Inert Gas or Water" (January 2011) of the German Central
Association for Sanitary, Heating and Air Conditioning (ZVSHK), the following
is defined with regard to the test methods A, B, C for pressure testing with water
offered in section 6.1 of EN 806-4:2010: "For reasons of practicability on the
building site, a modified method based on practical tests which can be used
for all materials and combinations of materials was chosen. The test time has
been extended in relation to the time specified in the standard to allow even
the slightest leaks to be detected. Test method B in accordance with DIN EN
806-4 is the basis for conducting the leak test with water for all materials." The
following is defined:
Leak testing with water can be conducted when
● changing of the water can be ensured at regular intervals, after seven days
at the latest, from the time of the leak test to commissioning of the drinking
water installation. Additionally when
● it is ensured that the house or building water connection is flushed and
therefore released for connection and operation,
● the pipe system is filled using totally hygienic components,
● the system remains full from the leak test to commissioning and partial
filling can be avoided.
WARNING
The hydro-pneumatic water pump installed additionally in the ROLLER'S
Multi-Control SLW for these tests is fed by the built-in compressor of the
ROLLER'S Multi-Control. The hydro-pneumatic pump generates a water pres-
sure of max. 1.8 MPa/18 bar/261 psi. Before conducting one of the tests with
water A, B, C, it must be assessed whether the installation to be tested will
withstand the preset/selected test pressure "p refer".
CAUTION
Before disconnecting the high-pressure hose (26) from the pressure test with
water drain (25) or from the drinking water installation, make sure that the
pressure has been totally relieved.
The programs can be aborted at any time with the Esc button (10). Then all
the valves open and the pressure in the installation is released. The tests are
saved but "Cancel" is shown in the file.
