The following must be observed for Germany
the disinfectant at all tapping points measured at the transition point (usually
the water meter) is reached or dropped below again.
To be observed for disposal: "If the water used for disinfection of an installation
is to be drained into a drain pipe or sewer, the responsible department must be
informed and the water may only be drained when the responsible department
has granted its permission." "Because of the rapid decomposition, the disposal
of hydrogen peroxide by draining into the sewer system is unproblematical."
and Commissioning of Drinking Water Installations" (August 2014) of the German
Central Association for Sanitary, Heating and Air Conditioning (ZVSHK). For
this length a volume of approx. 20 l is required for a ½" galvanised steel pipe
and a volume of approx. 100 l disinfectant for a 1 ¼" pipe (see Fig. 6: Volume
in l/m of different pipes).
Depending on the volume of the individual pipe sections, several pipe sections
can be disinfected with one bottle of REMS Peroxi Color dosing solution (see
Accessories 1.2 Article Numbers). However, it is recommended not to use an
opened bottle for longer than one day because the dosing solution loses in
concentration. 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 disin-
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 meas-
ured with the test strip (Art. No. 091072) according to the instructions printed
Open the bottle (21), remove the locking ring from the bottle cap and pour the
delivered dye (20 ml bottle) into the bottle (21) immediately before the disin-
fection process. Close the bottle and shake it so that the dye mixes evenly with
the hydrogen peroxide.

nozzles installed in REMS V-Jet TW and REMS V-Jet H for automatic dosing
of dosing solution, cleaner and corrosion protection are different sizes and
adapted to the properties of the REMS ingredients to be injected. Therefore
make absolutely sure that REMS V-Jet TW is connected for disinfection of
drinking water pipes. Select program Ingredients \ disinfection DW. During the

fection 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 REMS Multi-Push and the drain to the
drinking water installation must be shut off at the end of the disinfection process.

Additionally, peroxide test strips can be used if necessary to check the concen-

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".
The ambient temperature, the temperature of the test medium and the atmo-
measured pressures. Changes in these parameters must be considered, if
necessary, in the evaluation of the test results.
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 REMS Multi-Push
with compressed air, inert gas or water" (January 2011) of the German Central
Association for Sanitary, Heating and Air Conditioning (ZVSHK). Future changes
for the application site must be considered and changed test criteria (test
sequences, pressures and times) must be corrected in the defaults.

between 147 and 153 mbar or when setting p refer = 3 bar between 2.9 and
3.1 bar. This tolerance is safe because, in the pressure test with compressed
air, the relative pressure change of pressure p refer is decisive. If ENTER is
pressed, the value p actual is taken over as p refer. So the test can also be
begun at a p refer of 153 mbar for example.
