Then t the REMS ne lter (Fig. 3 (12)) (Art. No. 115609) with lter cartridge
90 µm. Connect the suction/pressure hose (Fig. 1 (13)) to the ushing supply
(14) after the ne lter. Fit the REMS V-Jet H (Fig. 7) cleaning and preservation
unit for heating systems with supply (Fig. 7 (16)) to the ushing drain of REMS
Multi-Push (Fig. 4 (15)). Observe the direction of ow 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 ow 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 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.
2.8. Compressedairpumpprogram
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. MemoryManagerprogram(datatransfer)
The results of the 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 3.6).
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
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 le
2. Unpack the ZIP 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 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.

The electronic memory of REMS Multi-Push holds 40 les (logs). A soon as a
program has been selected from the Start menu and the selected data have
been conrmed with Enter, a new le no. is created automatically even if the
program is then abortede.g. with Esc. If the 40th memory location is occupied,
the message "Last le no. available". After completing this process, all les

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 leaet "Flushing, disinfection
and commissioning of drinking water installations" (August 2014) of the German
Central Association for Sanitary, Heating and Air Conditioning (ZVSHK) the
ushing methods "ushing with water" and "Flushing with water/air mixture with
pressure surges" are described. REMS Multi-Push additionally offers the ushing
program "ushing with water/air mixture with constant compressed air".
Excerpt from EN 806-4:2010, 6.2.1. "The drinking water installation must be
ushed 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 ushed 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 leaet "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 ushing must be ltered whereby particles
≥ 150 µm must be held back and must be suitable for perfect drinking water
quality (use REMS ne lter and lter cartridge 90 µm, Art. No. 115609). The
system must be ushed 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 oor of the building and continue upwards in lines, within a line oor by
oor, i.e. from the nearest to the furthest line and oor. The minimum ow
velocity when ushing the installation must be 2 m/s and the water in the system
must be replaced at least 20 times during ushing.
Within the oor and single lines, at least as many tapping points as listed in the
following table as a recommended value for a ushing section will be fully
opened for at least 5 minutes oor by oor.

3.1.2. Flush with water/air mixture with intermittent compressed air program
The cleaning effect by ushing can be reinforced by adding compressed air. In
accordance with EN 806-4:2010 and information leaet "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 ushing must be ltrated whereby particles ≥ 150 µm
must be held back and the water must be perfectly t for drinking (REMS ne
lter with lter cartridge 90 µm, Art. No. 115609). "The pipe system can be ushed
under pressure with a drinking water/air mixture intermittently with a minimum
ow velocity in every pipe section of 0.5 m/s. A certain minimum number of tap
