therefore forms no critical decomposition products and can be drained into
sewers without problems because of its rapid decomposition. Besides, the
concentration of REMS Peroxi with 1.5 % hydrogen peroxide is not classifi ed
as dangerous (not a hazardous substance).
REMS Peroxi consists of a watery solution hydrogen peroxide corresponding
to the application concentration of the dosing solution of 1.5 % H
to 15 g/l H O recommended in the named rules. When diluted with 100 l of
2 2
water a concentration of the disinfection solution of 150 mg H
The advantage of the concentration of the dosing solution chosen by REMS is
also that the user gets a ready to use dosing solution which is not a hazardous
substance. Nevertheless, the safety data sheets for REMS Peroxi and REMS
Color under www.rems.de → Downloads → Safety Data Sheets as well as other
local and national regulations must be observed. Every REMS Peroxi dosing
solution comes with a REMS 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 fl ushed out
completely at the end of disinfection. The contents of a 1 l bottle of dosing
solution suffi ces 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 REMS fi ne fi lter (Fig. 3 (12)) (Art. No. 115609) with fi lter cartridge 90 µm
after the house connection (water meter). Connect the suction/pressure hose
(Fig. 1 (13)) to the fl ushing supply (14) before or after the fi ne fi lter. Fit the
REMS V-Jet TW with supply (Fig. 7 (16)) disinfection unit for drinking water
installations to the fl ushing drain of REMS Multi-Push (Fig. 4 (15)). Observe
the direction of fl ow 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 fl ow
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 NOTICE
The REMS V-Jet TW disinfection unit must be removed from REMS Multi-Push
to fl ush drinking water pipes after disinfection. Suction/pressure hoses used
for disinfection should be fl ushed 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 concen-
tration of the dosing solution should be checked for effectiveness before every
disinfection. To do this, fi ll 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 REMS Peroxi 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
The built-in nozzles for automatic dosing by REMS V-Jet TW and REMS V-Jet
H are different and are adapted to the properties of the REMS ingredients to
be injected. Therefore please always observe the intended use.

water" (January 2011) of the German Central Association for Sanitary, Heating water" (January 2011) of the German Central Association for Sanitary, Heating
and Air Conditioning (ZVSHK) and Air Conditioning (ZVSHK) (REMS Multi-Push SL/SLW)
WARNING WARNING
For Germany Germany the information leafl et "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) defi nes 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 defi ned 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 fulfi lled."
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".
Connect the compressed air hose (Fig. 4 (23)) to the output Pressure test with
compressed air, Disinfection, Cleaning, Preservation, Compressed air pump
(22) and connect the compressed air hose (23) to the installation to be tested.

WARNING WARNING
The hydro-pneumatic water pump installed additionally in the REMS Multi-Push
SLW for this test is fed by the built-in compressor of the REMS Multi-Push. The
hydro-pneumatic water pump generates a water pressure of max. 1.8 MPa/18
bar/261 psi. Before conducting one of the tests with water according to method
A, B, C, it must be assessed whether the installation to be tested will withstand
the preset/selected test pressure "p refer".
Fit the REMS fi ne fi lter (12) (Art. No. 115609) with fi lter cartridge 90 µm after
the house connection (water meter) (Fig. 3). Connect the suction/pressure hose
(13) to the pressure test with water supply (Fig. 1 (24)) after the fi ne fi lter.
Connect the high-pressure hose (26) to the pressure test with water drain (Fig. 4
(25)) and connect to the installation to be tested. Feed the pressure relief water
drain (27) into a vessel (bucket).

WARNING WARNING
For Germany, the technical rule for gas installations "Technical Rule Worksheet
G 600 April 2018 DVGW-TRGI 2018" of the DVGW German Gas and Water
Association defi nes the following among other things:
"5.6.2 Safety measures during the tests": Safety measures may need to be
taken during the tests when carrying out the load test due to the compressibility
of gases. "The max. test pressure may not exceed the value of 3 bar. Every
sudden rise in pressure in the pipe system to be tested must be avoided."
"5.6.3 Test media": "The tests in accordance with ... can be carried out option-
ally with air or inert gas (e.g. nitrogen). ...The use of oxygen is not permitted."
(The test with inert gases cannot be carried out with REMS Multi-Push).
"5.6.4 Pipe systems with operating pressures up to and including 100 mbar ...
are subjected to the following tests:
a) Load test
b) Leak test
c) Usefulness test for systems in operation" (this cannot be carried out with
REMS Multi-Push).
"5.6.4.1 The load test must be carried out before the leak test ..." "The test
pressure is 1 bar and may not drop during the test time of 10 minutes." "The
measuring device must have a minimum resolution of 0.1 bar".
"5.6.4.2 The leak test must be carried out after the load test..." The test pres-
sure must be 150 mbar and may not drop for the duration of the test." The
measuring device must have a minimum resolution of 0.1 mbar. Table 11

2.7 Programs Ingredients \ Cleaning and preservation of heating systems
Before cleaning and preserving heating systems with REMS Multi-Push, safety
devices for the prevention of drinking water contamination by fl owback, e.g.
pipe network separator BA in accordance with EN 1717:2000 must be installed
to protect the drinking water against contamination.

µm. Connect the suction/pressure hose (Fig. 1 (13)) to the fl ushing supply (14)
after the fi ne fi lter. Fit the REMS V-Jet H (Fig. 7) cleaning and preservation unit
for heating systems with supply (Fig. 7 (16)) to the fl ushing drain of REMS Multi-
Push (Fig. 4 (15)). Observe the direction of fl ow arrows. The main line of the
cleaning and preservation unit consists of the supply, pressure limiting valve (17),
non-return valve (18), drain to the heating system (19). This is connected to the
heating system to be cleaned by the suction/pressure hose (Fig. 4 (13)). Part of
the supply is pushed through the fl ow head (Fig. 7 (20)) into the bottle (21)
