of drinking water installations with compressed air, inert gas or water" (January
2011) of the German Central Association for Sanitary, Heating and Air Condi-
tioning (ZVSHK). All defaults for the test programs can be edited by the user
in the Settings menu and in the Flushing, Test with compressed air, Test with
water and Compressed Air Pump programs. Changes in the Settings menu are
saved, i.e. they reappear the next time the REMS Multi-Push is switched on.
If the defaults are only changed in one of the programs, the original defaults
appear again the next time the REMS Multi-Push is switched on. Reset resets
all defaults to factory settings and the language to German and the date, time,
units formats to DD.MM.YYYY, 24 h, m / bar.
Attention: The user is solely responsible for transferred or newly entered
test criteria (test sequences, pressures and times) or defaults in the
individual programs and the conclusions from the tests.
The respective national safety provisions, rules and regulations valid for
the application site must be considered and observed.
Before using the REMS Multi-Push, check whether the respective latest version
software is installed on the input and control unit. Select the Settings menu and
then Device data to display the version software. The latest version software
(Ver. Software) for the input and control unit is available by USB stick as a
download under www.rems.de → Downloads → Software. Compare the number
of the version software with the latest version software number and install the
latest version software on the input and control unit by means of a USB stick
if necessary. REMS Multi-Push must be switched off for this, switch off with the
On/Off button (Fig. 2 (4)) and pull out the mains plug if necessary. Insert the
USB stick with the latest version software into the USB port (Fig. 2 (33)). Plug
the mains plug into the socket. Press the Reset button (Fig. 1 (2)) of the PRCD
fault current circuit breaker (1). The control lamp (5) lights green. The latest
version software is installed. When a USB stick with LED is used, the LED
starts flashing. The installation is finished when the LED no longer flashes. If
the USB stick has no LED, you should wait about 1 minute after switching on
the PRCD. The latest version software is then installed on the input and control
unit. Pull out the USB stick.
Before starting up for the first time, the language, date and time should be set
in the Settings menu and the defaults for the individual programs checked and
changed if necessary.

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, REMS
Multi-Push must be connected to the water supply or the manifold of the instal-
lation (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 REMS 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).
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.
REMS therefore recommends disinfecting drinking water installations with
REMS Peroxi (hydrogen peroxide H
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 REMS Peroxi with 1.5 % hydrogen peroxide is not classified
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
sponding to 15 g/l H O recommended in the named rules. When diluted with
2 2
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 REMS is
also that the user gets a ready to use dosing solution which is not a hazardous
substance. Nevertheless, the safety data sheet for REMS Peroxi 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 flushed out completely at the end of
disinfection. The contents of a 1 l bottle of dosing solution suffices for disinfec-
tion 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 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
disinfection and cleaning unit (Fig. 7) with supply (Fig. 7 (16)) on the flushing
drain of the REMS Multi-Push (Fig. 4 (15)). Note the flow direction arrows. The
main line of the disinfection and cleaning unit consists of supply, pressure
limiting valve (17), non-return valve (18), drain to 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.
