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
(only 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. 115323) with filter cartridge 50 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 (neither of which is included in the scope of supply) for documentation.
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 T 82-2011 of the German Central Association for
Sanitary, Heating and Air Conditioning. 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
The flushing methods "flushing with water" and "flushing with water/air mixture
with pressure pulses" are described in EN 806-4:2010 and for Germany addi-
tionally in information leaflet T 84-2004 "Flushing, Disinfection and Commissioning
of Drinking Water Installations" of the German Central Association for Sanitary,
Heating and Air Conditioning. 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 information leaflet T 84-2004 of the
German Central Association for Sanitary, Heating and Air Conditioning, the
drinking water used for flushing must be filtrated whereby particles ≥ 150 µm
must be held back and the water must be perfectly fit for drinking (REMS fine
filter with filter cartridge 50 µm, Art. No. 115323). The system must be flushed
section for section depending on the size of the installation and the arrangement
and lay of the pipes. 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.
For Germany the following is prescribed additionally among other things in the
information leaflet T 84-2004 of the German Central Association for Sanitary,
Heating and Air Conditioning: "Flushing will take place floor by floor from the
end of the rise pipe. Within the floor and single lines, at least as many tapping
points as listed in Table 1 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" (Information
leaflet T 84-2004 of the German Central Association for Sanitary, Heating and
Air Conditioning, lines in italics added, limiting to DN 50)
REMS Multi-Push displays the achieved flow velocity and the achieved water
change on the screen among other things.

3.1.2. Flush with water/air mixture with intermittent compressed air program
The cleaning effect by flushing can be reinforced by adding compressed air. In
accordance with EN 806-4:2010 and information leaflet T 84-2004 of the German
Central Association for Sanitary, Heating and Air Conditioning, the drinking
water used for flushing must be filtrated whereby particles ≥ 150 µm must be
held back and the water must be perfectly fit for drinking (REMS fine filter with
filter cartridge 50 µm, Art. No. 115323). "The pipe system can be flushed under
pressure with a drinking water/air mixture intermittently with a minimum flow
velocity in every pipe section of 0.5 m/s. A certain minimum number of tap
fittings must be opened for this. If the minimum volume flow is not reached with
full filling of the distribution pipe in a section of the pipe system to be flushed,
a storage tank and a pump must be used for flushing." "The system must be
flushed section by section depending on the size of the installation and the lay
of the pipes. No flushing section may exceed a pipe section length of 100 m."
