advise against buying disinfectants, e.g. hydrogen peroxideH

, with higher

concentrations which the user then has to dilute to the recommended concen-

tration of the dosing solution. Such actions are dangerous due to the higher

concentrations of the disinfectants so that hazardous substance and chemical

prohibition directives and possibly other national laws must be observed. In

addition, errors in the preparation of the self-mixed dosing solution can cause

harm to persons and damage to the drinking water installati

on.

Preparing for installation

t the REMS ﬁ ne ﬁ lter (Fig. 3 (12)) (Art. No. 115609) with ﬁ lter cartridge 90 µm

after the house connection (water meter). Connect the suction/pressure hose

(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 REMS ingredients to

be injected. Therefore please always observe the intended use.

pipe network separator BA in accordance with EN 1717:2000 must be installed

to protect the drinking water against contamination.

Fit 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 REMS CleanH cleaner or REMS NoCor corrosion protection

for heating systems. These are fed into the heating system to be cleaned or

protected against corrosion. The contents of the 1 l bottle of REMS CleanH or

REMS NoCor is sufﬁ cient for a volume of approx. 100 l. REMS CleanH is dyed

green in order to be able to check ﬁ lling and washout, REMS NoCor is dyed

blue to check ﬁ lling. The safety data sheets for REMS CleanH and REMS

NoCor under www.rems.de → Downloads → Safety Data Sheets as well as

other local and national regulations must be observed.

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.
