2.4. Flushing programs
To flush pipe systems with water, with water/air mixture with intermittent
compressed air and with water/air mixture with constant compressed air,
ROLLER'S Multi-Control must be connected to the water supply or the manifold
of the installation (Fig. 3) or to the heating system (Fig. 5) as follows:
To flush drinking water pipes after the house connection (water meter) (Fig. 3),
fit the ROLLER'S fine filter (12) (Art. No. 115609) with filter cartridge 90 µm.
Connect the suction/pressure hose (13) to the flushing supply (14) after the
fine filter. Fit the second suction/pressure hose (13) to the flushing drain (Fig.
4 (15)) and connect to the installation to be flushed. Suction/pressure hoses
used for drinking water should not be used for disinfection or for heating.
Proceed accordingly to flush heating systems (Fig. 5). Proceed accordingly for
flushing heating systems (Fig. 5).
To flush drinking water pipes, a fine filter (12) must be available after the house
connection (water meter) (Fig. 3). If not, fit ROLLER'S fine filter (Art. No.
115609) with filter cartridge 90 μm between the suction/pressure hose (13) and
the flushing supply (14). Fit the second suction/pressure hose (13) to the flushing
drain (Fig. 4 (15)) and connect to the installation to be flushed.
Proceed accordingly to flush heating systems (Fig. 5). However, it is necessary
to fit a system separator in accordance with EN 1717:2000 after the house
connection (water meter) (Fig. 5) to prevent contamination of drinking water by
flowback. Do not use suction/pressure hoses for drinking water lines any more
after they have been used for heating systems.
2.5. Program "Disinfection"
WARNING
The European standard EN 806-4: 2010 prescribes the following for the
"Selection of disinfectants":
"Drinking water installations may be disinfected after flushing if this is prescribed
by a responsible person or authority."
"All chemicals that are used for the disinfection of drinking water installations
must meet the requirements for chemicals for water treatment which are spec-
ified in European standards or, if European standards are not applicable, in
national standards and technical rules." Moreover:
"Disinfectants must be used and applied in agreement with the appropriate EC
directives and all local or national regulations."
"Transport, storage, handling and use of all these disinfectants can be dangerous,
therefore health and safety regulations must be strictly observed."
In Germany the Technical Rules – Worksheet DVGW W 557 (A) October
2012 of the DVGW German Association of the Gas and Water Industry e.
V. and the information leaflet "Flushing, disinfection and commissioning
of drinking water installations" (August 2014) of the German Central
Association for Sanitary, Heating and Air Conditioning (ZVSHK) recom-
mends hydrogen peroxide H
dioxide ClO for the disinfection of drinking water installations.
2
User friendliness, work protection and environmental protection etc. must be
considered in the choice of disinfection chemicals. It should be noted that, when
using oxidants containing chlorine (sodium hypochlorite NaOCl and chlorine
dioxide ClO ), for example, chlorine organic compounds may form which are
2
to be considered harmful to the environment.
ROLLER'S therefore recommends disinfecting drinking water installations with
ROLLER'S Plus TW-D (hydrogen peroxide H
the better alternative with regard to use friendliness, work protection and
environmental protection because it decomposes into hydrogen and water
when used and therefore forms no critical decomposition products and can be
drained into sewers without problems because of its rapid decomposition.
Besides, the concentration of ROLLER'S Plus TW-D with 1.5 % hydrogen
peroxide is not classified as dangerous (not a hazardous substance).
ROLLER'S Plus TW-D consists of a watery solution hydrogen peroxide corre-
sponding to the application concentration of the dosing solution of 1.5 % H
corresponding to 15 g/l H
with 100 l of water a concentration of the disinfection solution of 150 mg H
results.
The advantage of the concentration of the dosing solution chosen by ROLLER'S
is also that the user gets a ready to use dosing solution which is not a hazardous
substance. Nevertheless, the safety data sheets for ROLLER'S Plus TW-D and
ROLLER'S Color under www.albert-roller.de → Downloads → Safety data
sheets as well as other local and national regulations must be observed. Every
ROLLER'S Plus TW-D dosing solution comes with a ROLLER'S Color dye that
is not harmful to the health which is mixed with the dosing solution immediately

before the disinfection process and dyes this. This enables a simple check
whether the disinfection solution has entered the drinking water installation and
whether it has been flushed out completely at the end of disinfection. The
contents of a 1 l bottle of dosing solution suffices for disinfection of a section
with a volume of approx. 100 l.
We advise against buying disinfectants, e.g. hydrogen peroxideH
concentrations which the user then has to dilute to the recommended concen-
tration of the dosing solution. Such actions are dangerous due to the higher
concentrations of the disinfectants so that hazardous substance and chemical
prohibition directives and possibly other national laws must be observed. In
addition, errors in the preparation of the self-mixed dosing solution can cause
harm to persons and damage to the drinking water installation.
Fit the ROLLER'S fine filter (Fig. 3 (12)) (Art. No. 115609) with filter cartridge
90 µm after the house connection (water meter). Connect the suction/pressure
hose (Fig. 1 (13)) to the flushing supply (14) before or after the fine filter. Fit
the ROLLER'S Inject TW with supply (Fig. 7 (16)) disinfection unit for drinking
water installations to the flushing drain of ROLLER'S Multi-Control (Fig. 4 (15)).
Observe the direction of flow arrows. The main line of the disinfection unit
consists of the supply, pressure limiting valve (17), non-return valve (18), drain
to the installation (19). This is connected to the installation to be infected by
the suction/pressure hose (Fig. 4 (13)). Part of the supply is pressed by the
flow head (Fig. 7 (20)) into the bottle (21) which contains the dosing solution.
This is fed to the drinking water installation to be disinfected.
NOTICE
The ROLLER'S Inject TW disinfection unit must be removed from ROLLER'S
Multi-Control to flush drinking water pipes after disinfection. Suction/pressure
hoses used for disinfection should be flushed thoroughly before using for
pressure testing of drinking water pipes. Hydrogen peroxide decomposes in
time and loses its effect depending on the environment in which it is stored.
Therefore the concentration of the dosing solution should be checked for
effectiveness before 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 concen-
tration 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 O .
2 2
The built-in nozzles for automatic dosing by ROLLER'S Inject TW and ROLL-
ER'S Inject H are different and are adapted to the properties of the ingredients
to be injected. Therefore please always observe the intended use.
Only connect the cleaning and preservation unit (Fig. 7) to the flushing drain
of ROLLER'S Multi-Control (Fig. 4 (15)). Never allow cleaner or corrosion
protection agent to flow though the pipes of ROLLER'S Multi-Control.
2.6. Testing programs
2.6.1. Leak and load testing with compressed air according to 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)
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 associa-
tion 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".
