NOTICE
REMS Multi-Push is not intended/suitable for permanent connection to the
installation. Disconnect all hoses from the installation after completing the work.
REMS Multi-Push may not be operated unattended.
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: www.rems.de → Downloads → Software → REMS Multi-Push →
Download. Compare the number of the version software of the unit with the
latest version software number and install the latest version software if neces-
sary.
Download procedure:
1. Download fi le
2. Unpack the ZIP fi le
3. Save "update.bin" on USB stick
4. Plug the USB stick into the USB port of the REMS Multi-Push
See 2.3 for the further procedure.
NOTICE
The defaults for the different test criteria (test sequences, pressures and times)
in the settings menu of the REMS Multi-Push are taken from EN 806-4:2010
or 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). 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
(deu) 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. Especially, the
user must decide whether a prescribed stabilisation/wit time is ended
and must confi rm this by \Enter.
The respective national safety provisions, rules and regulations valid for
the application site must be considered and observed.
The electronic memory of REMS Multi-Push holds 40 fi les (logs). A soon as a
program has been selected from the Start menu and the selected data have
been confi rmed with Enter, a new fi le no. is created automatically even if the
program is then aborted e.g. with Esc. If the 40th memory location is occupied,
the message "Last fi le no. available". After completing this process, all fi les
should be copied to a USB stick via the USB port (Fig. 2 (33)). The oldest fi le
no. in the memory is then overwritten when further fi les are saved.

3.1 Flushing of drinking water installations programs
In EN 806-4:2010 and for Germany additionally in Technical Rules – Worksheet
DVGW W 557 (A) October 2012 of the DVGW German Association of the Gas
and Water Industry e.V. and in the information leafl et "Flushing, disinfection
and commissioning of drinking water installations" (August 2014) of the German
Central Association for Sanitary, Heating and Air Conditioning (ZVSHK) the
fl ushing methods "fl ushing with water" and "Flushing with water/air mixture with
pressure surges" are described. REMS Multi-Push additionally offers the fl ushing
program "fl ushing with water/air mixture with constant compressed air".
Excerpt from EN 806-4:2010, 6.2.1 "The drinking water installation must be
fl ushed with drinking water after installation and pressure testing as well as
immediately before commissioning." "If a system is not put into operation imme-
diately after commissioning, it must be fl ushed at regular intervals (up to 7 days)."
3.1.1 Flushing with water program (without air supply) 3.1.1 Flushing with water program (without air supply)
In accordance with EN 806-4:2010 and for Germany
with the Technical Rule – Worksheet DVGW W 557 (A) October 2012 of the

disinfection and commissioning of drinking water installations" (August 2014)
of the Central Association for Sanitary, Heating, Air Conditioning (ZVSHK),
Germany, the drinking water used for fl ushing must be fi ltered and must be of
perfect drinking water quality. Filters must hold back particles ≥ 150 µm (Use
REMS fi ne fi lter with fi lter cartridge 90 µm, Art. No. 115609). The system must
be fl ushed section for section depending on the size of the installation and the
arrangement and lay of the pipes. Flushing must be start on the bottom fl oor

opened for at least 5 minutes fl oor by fl oor.

Association for Sanitary, Heating and Air Conditioning, lines in italics added,
limiting to DN 50). Two or more REMS Multi-Push can be connected in parallel
to fl ush greater rated widths.

3.1.2 Flush with water/air mixture with intermittent compressed air program 3.1.2 Flush with water/air mixture with intermittent compressed air program
The cleaning effect by fl ushing can be reinforced by adding compressed air. In
accordance with EN 806-4:2010 and information leafl et "Flushing, disinfection
and commissioning of drinking water installations" (August 2014) of the German
Central Association for Sanitary, Heating and Air Conditioning (ZVSHK), the
drinking water used for fl ushing must be fi ltrated whereby particles ≥ 150 µm
must be held back and the water must be perfectly fi t for drinking (REMS fi ne
fi lter with fi lter cartridge 90 µm, Art. No. 115609). "The pipe system can be fl ushed
under pressure with a drinking water/air mixture intermittently with a minimum
fl ow velocity in every pipe section of 0.5 m/s. A certain minimum number of tap
fi ttings must be opened for this. If the minimum volume fl ow is not reached with
full fi lling of the distribution pipe in a section of the pipe system to be fl ushed, a
storage tank and a pump must be used for fl ushing." "The system must be fl ushed
section by section depending on the size of the installation and the lay of the
pipes. No fl ushing section may exceed a pipe section length of 100 m."

REMS Multi-Push can be connected in parallel to fl ush greater rated widths.
The manual actuation of the setting fi ttings for the supply of intermittent
compressed air described in EN 806-4:2010 and in the information leafl et
"Flushing, Disinfection and Commissioning of Drinking Water Installations"
(August 2014) of the German Central Association for Sanitary, Heating and Air
Conditioning (ZVSHK) takes place automatically in REMS Multi-Push. The
compressed air is fed with an excess pressure of 0.5 bar above the measured
water pressure. The compressed air supply lasts 5 s, the stagnation phase
(without compressed air) lasts 2 s.
REMS Multi-Push displays the achieved fl ow velocity and the achieved volume
fl ow on the screen among other things.
