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 fl ashing. The
installation is fi nished when the LED no longer fl ashes. 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

To fl ush 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 fl ush drinking water pipes after the house connection (water meter) (Fig. 3),
fi t the REMS fi ne fi lter (12) (Art. No. 115609) with fi lter cartridge 90 µm. Connect
the suction/pressure hose (13) to the fl ushing supply (14) after the fi ne fi lter.
Fit the second suction/pressure hose (13) to the fl ushing drain (Fig. 4 (15)) and
connect to the installation to be fl ushed.
Proceed accordingly to fl ush heating systems (Fig. 5). However, it is necessary
to fi t a system separator in accordance with EN 1717:2000 after the house
connection (water meter) (Fig. 5) to prevent contamination of drinking water by
fl owback. Do not use suction/pressure hoses for drinking water lines any more
after they have been used for heating systems.
2.5 Program Ingredients/Disinfection
The European standard EN 806-4:2010
prescribes the following for the
“Selection of disinfectants”:
“Drinking water installations may be disinfected after fl ushing 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-
ifi ed in European standards or, if European standards are not applicable, in
national standards and technical rules.”
“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 th
ese disinfectants can be dangerous,
therefore health and safety regulations must be

User friendliness, work protection a

REMS therefore recommends di
sinfecting drinking water installations with
REMS Peroxi (hydrogen peroxide H
). Hydrogen peroxide offers 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 REMS Peroxi with 1.5 % hydrogen peroxide is not classifi ed
as dangerous (not a hazardous substan

is mixed with the dosing solution immediately before the disinfection process
