Information for use
Corrosion
Overground pipelines and fittings in rooms do not normally require external corrosion protection.
There are exceptions in the following cases:
Contact with aggressive building materials such as nitrite or materials containing ammonium
in aggressive surroundings
INFO!
The one-piece Easytop extraction valve made of gunmetal/silicon bronze can be used for all types of potable water.
The chloride concentration in the medium must not exceed a maximum value of 250 mg/l.
This chloride is not a disinfectant, but in fact pertains to the content in sea and table salt (sodium chloride).
Required accessories
An adapter nipple (model 2223.5) is required for the mounting of the model with a G⅜ internal thread.
Handling
Assembly information

The positioning of the extraction valve should take place in accordance with the recommendations of the applicable directives; existing testing or drainage openings on fittings can be used, see Standards and regulations .
The extraction valve can be mounted on various axes of rotation in nearly all positions of a system:
360° rotatable outlet pipe
Base unit rotatable through 360° on the actuation unit
Checking system components
INFO!
Do not remove the model from the packaging until immediately before use.
System components may, in some cases, become damaged through transportation and storage.
Check all parts.
Replace damaged components.
Do not repair damaged components.
Contaminated components may not be installed.
Required tools
The following tools are required for mounting the model:
Allen key (size 5) for drain plug on the Easytop fittings
Open-end spanner (size 17) and if required (size 19) for adapter nipple
Assembly
Mounting the extraction valve
Mount extraction valve in a G ¼ internal thread
INFO!
A leakage and functionality test must be carried out after mounting.
Before fitting the extraction valve, check that the system has been depressurised.
-
Unscrew the drain plug with an Allen key (SW 5).
-
Screw in the extraction valve with a fork spanner (SW 17).
INFO!The handwheel can be removed in the case of reduced accessibility. By doing that, an additional key surface (size 14) is made available.
Mounting extraction valve in a G ⅜ internal thread
INFO!
Carry out a leak test and a function test on completion of initial fitting.
Before fitting the extraction valve, check that the system has been depressurised.
-
Unscrew the drain plug with an Allen key (SW 5).
-
Screw in the adapter nipple with a fork spanner (SW 19).
INFO!Screw in the Teflon® seal as far as it will go.
-
Screw in the extraction valve with a fork spanner (SW 17).
INFO!The handwheel can be removed in the case of reduced accessibility. By doing that, an additional key surface (size 14) is made available.
Leakage test
The installer must perform a leakage test before commissioning.
Carry out this test on a system that is finished but not covered yet.
Comply with the general rules of engineering and the applicable directives, see Regulations from section: Leakage test .
Document the result.
Control
Sample extraction
Disinfect outlet pipe
INFO!
Disinfect or sterilise the outlet pipe every time prior to sampling.
The extraction valve can also be operated using a bleeding key when the handwheel is removed.
-
Thermally or chemically disinfect or sterilise the outlet pipe, e.g. using flame treatment.
In the following, thermal disinfection is explained by way of example using the sampling valve on a circulation control valve.
You might need to remove the handwheel in difficult installation situations prior to flame treatment.
Direct contact of the flame with the electronic circulation control valve and the insulation shell will cause damage.
Do not point the flame in the direction of the valve.
-
Turn the outlet pipe away from the electronic circulation control valve and the insulation shell.
-
Carefully heat the outlet tube with a standard burner (butane / propane burner / soldering flame).
Danger of burns from flame and hot surfaces.
Do not touch hot surfaces or naked flames or come into contact with flammable objects.
-
For even heating of the outlet tube, pass the flame between the tube bend and the outlet in both directions.
-
Heat the tube evenly. If the outlet pipe is heated evenly and the flame is guided carefully, there is no danger of damaging the valve.
-
The outlet pipe should reach a temperature of approx. 80 °C. If the flame is guided evenly along the tube, a temperature of approx. 80 °C is reached after approx. 20‑30 seconds with a standard burner.
-
Immediately after flaming and opening the sampling valve, a hissing sound should be audible.
Sample
-
Open the valve using the handwheel and extract a water sample.
-
After extracting the sample, close the valve using the handwheel.
Mounting the signage
INFO!
Sampling points must be labelled in such a way as to avoid confusion and in compliance with applicable guidelines, see Standards and regulations .
The signage (writeable) can be mounted behind the handwheel.
-
Remove the handwheel from the actuation unit.
-
Attach the signage.
-
Re-attach the handwheel.
Disposal
Separate the product and packaging materials (e. g. paper, metal, plastic or non-ferrous metals) and dispose of in accordance with valid national legal requirements.
