NOTICE
To flush drinking water pipes after disinfection, the disinfection unit must be
removed from the REMS Multi-Push.
The suction/pressure hose (Fig. 4 (13)) used for draining the disinfection solu-
tion to the installation (19) should no longer be used for flushing and pressure
testing of drinking water installations.
Only connect the disinfection or cleaning unit (Fig. 7) to the flushing drain of
REMS Multi-Push (Fig. 4 (15)). Never let disinfectants or cleaners flow through
the pipes/hoses of REMS Multi-Push.
Hydrogen peroxide decomposes in time and loses its effect. The best before
date on the REMS Peroxi Color bottle should be observed.
2.6. Testing programs
2.6.1. Leak and load testing with compressed air according to 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)
WARNING
For Germany 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) defines the
following for the national regulations under "3.1 General":
"Due to the compressibility of gases, the rules for the prevention of accidents
"Working on Gas Systems" and the "Technical Rules for Gas Installations
DVGW-TRGI" must be observed for physical and safety reasons when conducting
pressure tests with air Therefore, the test pressures have been defined as
maximum 0.3 MPa/3 bar/43.5 psi, the same as for load and leak tests for gas
pipes, in agreement with the responsible industrial liability insurance associa-
tion and based on these rules. The national regulations are thereby fulfilled."
The respective national safety provisions, rules and regulations valid for
the application site must be considered and observed.
Before conducting a test with compressed air, it must be assessed whether the
installation to be tested will withstand the preset / selected test pressure "p
refer".
Connect the compressed air hose (Fig. 4 (23)) to the output Pressure test with
compressed air, Disinfection, Cleaning, Preservation, Compressed air pump
(22) and connect the compressed air hose (23) to the installation to be tested.
2.6.2. Pressure and leak test with water in accordance with EN 806-4:2010
(REMS Multi-Push SLW)
WARNING
The hydro-pneumatic water pump installed additionally in the REMS Multi-Push
SLW for this test is fed by the built-in compressor of the REMS Multi-Push. The
hydro-pneumatic water pump generates a water pressure of max. 1.8 MPa/18
bar/261 psi. Before conducting one of the tests with water according to method
A, B, C, it must be assessed whether the installation to be tested will withstand
the preset/selected test pressure "p refer".
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. 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.
2.8. 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).
2.9. 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
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. 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, Technical Rules – Worksheet DVGW W
557 (A) October 2012 of the DVGW German Association of the Gas and Water
Industry e. V. and 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 drinking water used
for flushing must be filtered whereby particles ≥ 150 µm must be held back and
must be of perfect drinking water quality (use REMS fine filter with 90 µm filter
cartridge, Art. No. 115609). The system must be flushed 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 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
