(Fig. 1 (13)) to the fl ushing supply (14) before or after the fi ne fi lter. Fit the
REMS V-Jet TW with supply (Fig. 7 (16)) disinfection unit for drinking water
installations to the fl ushing drain of REMS Multi-Push (Fig. 4 (15)). Observe
the direction of fl ow arrows. The main line of the disinfection unit consists of
the supply, pressure limiting valve (17), non-return valve (18), drain to the
installation (19). This is connected to the installation to be infected by the
suction/pressure hose (Fig. 4 (13)). Part of the supply is pressed by the fl ow
head (Fig. 7 (20)) into the bottle (21) which contains the dosing solution. This
is fed to the drinking water installation to be disinfected.
NOTICE
The REMS V-Jet TW disinfection unit must be removed from REMS Multi-Push
to fl ush drinking water pipes after disinfection. Suction/pressure hoses used
for disinfection should be fl ushed thoroughly before using for pressure testing
of drinking water pipes. Hydrogen peroxide decomposes in time and loses its
effect depending on the environment in which it is stored. Therefore the concen-
tration of the dosing solution should be checked for effectiveness before every
disinfection. To do this, fi ll a clean, sealable container with 100 ml of water and
draw 1 ml of dosing solution from the bottle using the pipette provided with
every carton of REMS Peroxi Color and add it to the container (ratio 1:100).
Seal the container and shake well. The concentration of the container contents
is measured with the test strip (Art. No. 091072) according to the instructions
printed on the test strip package. This should be ≥ 150 mg/l H
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 ingredients to be injected.
Therefore please always observe the intended use.
Only connect the cleaning and preservation unit (Fig. 7) to the fl ushing drain
of REMS Multi-Push (Fig. 4 (15)). Never allow cleaner or corrosion protection
agent to fl ow though the pipes of REMS Multi-Push.

"Leak tests of drinking water installations with compressed air, inert gas or "Leak tests of drinking water installations with compressed air, inert gas or
water" (January 2011) of the German Central Association for Sanitary, Heating water" (January 2011) of the German Central Association for Sanitary, Heating
and Air Conditioning (ZVSHK) and Air Conditioning (ZVSHK)
WARNING
For Germany Germany 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) defi nes 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 defi ned 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 fulfi lled."
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 testing of drinking water installations with water in 2.6.2 Pressure and leak testing of drinking water installations with water in
accordance with EN 806-4:2010 (REMS Multi-Push SLW) accordance with EN 806-4:2010 (REMS Multi-Pus
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 fi ne fi lter (12) (Art. No. 115609) with fi lter cartridge 90 µm after
the house connection (water meter) (Fig. 3). Connect the suction/pressure hose
(13) to the pressure test with water supply (Fig. 1 (24)) after the fi ne fi lter.
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).

WARNING
For Germany, the technical rule for gas installations "Technical Rule Worksheet
G 600 April 2008 DVGW-TRGI 2008" of the DVGW German Gas and Water
Association defi nes the following among other things:
"5.6.2 Safety measures during the tests": Safety measures may need to be
taken during the tests when carrying out the load test due to the compressibility
of gases. "The max. test pressure may not exceed the value of 3 bar. Every
sudden rise in pressure in the pipe system to be tested must be avoided."

REMS Multi-Push).
"5.6.4.1 The load test must be carried out before the leak test ..." "The test
pressure is 1 bar and may not drop during the test time of 10 minutes." "The
measuring device must have a minimum resolution of 0.1 bar".
"5.6.4.2 The leak test must be carried out after the load test..." The test pres-
sure must be 150 mbar and may not drop for the duration of the test." The

This rule of the legal German accident insurance must also be observed for
Germany. "Operation of work equipment", BGR 500, April 2008, chap. 2.31,
Work on gas pipes, industrial liability insurance association rule.
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, Compressed air pump (22) and connect the compressed air
hose (23) to the installation to be tested.
Before cleaning and preserving heating systems with REMS Multi-Push, safety
devices for the prevention of drinking water contamination by fl owback, e.g.
pipe network separator BA in accordance with EN 1717:2000 must be installed
to protect the drinking water against contamination.
Then fi t the REMS fi ne fi lter (Fig. 3 (12)) (Art. No. 115609) with fi lter cartridge 90
µm. Connect the suction/pressure hose (Fig. 1 (13)) to the fl ushing supply (14)
after the fi ne fi lter. Fit the REMS V-Jet H (Fig. 7) cleaning and preservation unit
for heating systems with supply (Fig. 7 (16)) to the fl ushing drain of REMS Multi-
Push (Fig. 4 (15)). Observe the direction of fl 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 fl 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 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.
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 value
0.02 MPa / 0.2 bar / 3 psi is preset.
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).
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).
