REMS NoCor is suffi cient for a volume of approx. 100 l. REMS CleanH is dyed
green in order to be able to check fi lling and washout, REMS NoCor is dyed
blue to check fi lling. The safety data sheets for REMS CleanH and REMS
NoCor under www.rems.de → Downloads → Safety Data Sheets as well as
other local and national regulations must be observed.
NOTICE
NOTICE
Never allow cleaner or corrosion protection agent to fl ow though the pipes of
REMS Multi-Push.
Do not use suction/pressure hoses for drinking water lines any more after they
have been used for heating systems.
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.
2.8 Compressed air pump program (REMS Multi-Push SL/SLW)
Vessels of all types can be pumped up with this program. Connect the compressed
air hose (23) to the output Pressure test with compressed air, Compressed air
pump (Fig. 4 (22)) and connect it to the vessel to be pumped up, e.g. expansion
vessel, tyre. The value 0.02 MPa / 0.2 bar / 3 psi is preset.
2.9 Memory Manager program (data transfer)
The results of the fl ushing and test programs are saved with date, time and log
number in the selected language and can be transferred to a USB stick or
printer (accessory part no. 115604) (neither of which is included in the scope
of supply) for documentation (see 3.8).
2.10 Compressed air tools connection
Unlike the described "Compressed Air Pump" program in which the values are
controlled by the electronic control, compressed air tools up to a max. air
requirement of 230 Nl/min can be operated directly from the compressed air
vessel at the compressed air tools connection (Fig. 4 (28)). A compressed air
hose with quick couplings NW 7.2 must be used (accessory part no. 115621).
3 Operation
NOTICE
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. For REMS Multi-Push S the
use of software version as of "03.40, Date 2020-04-08" is permitted. 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 soft-
ware if necessary.
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.

The defaults for the different test criteria (test sequences, pressures and times)
in the settings menu of the REMS Multi-Push SL/SLW 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 SL/SLW 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 SL/SLW 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.

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)."

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
of the building and continue upwards in lines, within a line fl oor by fl oor, i.e.
from the nearest to the furthest line and fl oor. The minimum fl ow velocity when
fl ushing the installation must be 2 m/s and the water in the system must be
replaced at least 20 times during fl ushing.
Within the fl oor and single lines, at least as many tapping points as listed in the
following table as a recommended value for a fl ushing section will be fully
opened for at least 5 minutes fl oor by fl oor.
