Fit the REMS fine filter (12) (Art. No. 115609) with filter cartridge 90 µm after
the house connection (water meter). Connect the suction/pressure hose (13)
to the pressure test with water supply (Fig. 1 (24)) after the fine filter. Connect
the high-pressure hose (26) to the pressure test with water drain (Fig. 4 (25))
and connect to the installation to be tested. Feed the pressure relief water drain
(27) into a vessel (bucket).
2.7. Cleaning and preservation of heating systems
Before cleaning and preserving heating systems with REMS Multi-Push, safety
devices for the prevention of drinking water contamination by flowback, e.g.
pipe network separator BA in accordance with EN 1717:2000 must be installed
to protect the drinking water against contamination.
Then fit the REMS fine filter (Fig. 3 (12)) (Art. No. 115609) with filter cartridge
90 µm. Connect the suction/pressure hose (Fig. 1 (13)) to the flushing supply
(14) after the fine filter. Fit the REMS V-Jet H (Fig. 7) cleaning and preservation
unit for heating systems with supply (Fig. 7 (16)) to the flushing drain of REMS
Multi-Push (Fig. 4 (15)). Observe the direction of flow arrows. The main line of
the cleaning and preservation unit consists of the supply, pressure limiting valve
(17), non-return valve (18), drain to the heating system (19). This is connected
to the heating system to be cleaned by the suction/pressure hose (Fig. 4 (13)).
Part of the supply is pushed through the flow head (Fig. 7 (20)) into the bottle
(21) which contains the cleaner or corrosion protection for heating systems.
These are fed into the heating system to be cleaned or protected against
corrosion.
NOTICE
Never allow cleaner or corrosion protection agent to flow 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.
2.8. Compressed air pump program
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, Disinfection,
Cleaning, Preservation, Compressed air pump (Fig. 4 (22)) and connect it to
the vessel to be pumped up, e.g. expansion vessel, tyre. The default is displayed
as 0.02 MPa/0, 2 bar/3 psi.
2.9. Memory Manager program (data transfer)
The results of the flushing 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 3.6).
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 (available as an accessory).
3. Operation
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 file
2. Unpack the ZIP file
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 leaflet "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 confirm 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 files (logs). A soon as a
program has been selected from the Start menu and the selected data have
been confirmed with Enter, a new file no. is created automatically even if the
program is then abortede.g. with Esc. If the 40th memory location is occupied,
the message "Last file no. available". After completing this process, all files
should be copied to a USB stick via the USB port (Fig. 2 (33)). The oldest file
no. in the memory is then overwritten when further files 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 leaflet "Flushing, disinfection
and commissioning of drinking water installations" (August 2014) of the German
Central Association for Sanitary, Heating and Air Conditioning (ZVSHK) the
flushing methods "flushing with water" and "Flushing with water/air mixture with
pressure surges" are described. REMS Multi-Push additionally offers the flushing
program "flushing with water/air mixture with constant compressed air".
Excerpt from EN 806-4:2010, 6.2.1. "The drinking water installation must be
flushed with drinking water after installation and pressure testing as well as
immediately before commissioning." "If a system is not put into operation
immediately after commissioning, it must be flushed at regular intervals (up to
7 days)."
3.1.1. Flushing with water program (without air supply)
In accordance with EN 806-4:2010 and for Germany additionally in accordance
with the Technical Rule – Worksheet DVGW W 557 (A) October 2012 of the
DVGW German Gas and Water Association and the information leaflet "Flushing,
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 flushing must be filtered whereby particles
≥ 150 µm must be held back and must be suitable for perfect drinking water
quality (use REMS fine filter and filter cartridge 90 µm, Art. No. 115609). The
system must be flushed section for section depending on the size of the instal-
lation and the arrangement and lay of the pipes. Flushing must be start on the
bottom floor of the building and continue upwards in lines, within a line floor by
floor, i.e. from the nearest to the furthest line and floor. The minimum flow
velocity when flushing the installation must be 2 m/s and the water in the system
must be replaced at least 20 times during flushing.
Within the floor and single lines, at least as many tapping points as listed in the
following table as a recommended value for a flushing section will be fully
opened for at least 5 minutes floor by floor.
Greatest rated width of the pipe in the
flushed section, DN
Greatest rated width of the pipe in the flushed
section, in inches
Minimum number of tapping points to be
opened DN 15 (½")
Table 1: Recommended value for the minimum number of tapping points to be
opened related to the greatest rated width of the distribution line" (single tapping
rate at least 10l/20 s) (Information leaflet "Flushing, disinfection and commis-
sioning of drinking water installations" (August 2014) of the German Central
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 flush greater rated widths.
REMS Multi-Push displays the achieved flow velocity and the achieved water
change on the screen among other things.
