You can reduce the operating pressure when gas is extracted. Turn the hand-wheel to the left until
the required pressure has been reached. If you are only extracting small amounts of gas, this pressure
reduction may take some time.
notiCe! The red mark on the pressure gauge marks the permissible outlet pressure. The limitation
of the outlet pressure set in the factory ensures that the max. permissible operating pressure is not
exceeded!
6.2.3 additional equipment for r 40/r 12
Danger! Before starting assembly, de-pressurize the gas supply system. Depending on the type of gas,
remaining gases in the tubes must be removed. Danger of ignition, explosion or poisoning!
On the outlet pressure side of the point of use regulator, the following additional equipment can be
mounted:
Regulating valve V 50, flame arrestors, flow meter, pressure gauge, compression fitting, hose nipples,
protection plugs (male). There are three available mounting positions. The are on the circumference of
the regulator on top, on the right and on the bottom. They are each 90° apart respectively.
Mounting additional equipment
When mounting additional equipment a difference is made between those with a fixed mounting
position (pressure gauge, flow meter and regulating valve) and those without a fixed mounting position
(flame arrestor, compression fitting and hose nipple). The pressure gauge is usually mounted on top, the
regulating valve on the right (or at the bottom), the flow meter on the right. The compression fitting, the
flame arrestor and the hose nipple are usually mounted at the bottom. The gas escape drilled holes which
are not being used must be sealed with a protection plug G 1/4".
To mount to various additional equipment you will need the following tools: Fork spanners: SW 14, SW
19, SW 22, Allan key: SW 7.
Mounting the compression fitting or the hose nipple
Remove the protection plug from the intended mount of the point of use regulator. Insert a gasket
G
1/4" – 11.2 x 5.5 x 1.5 mm in this port on the regulator and screw the compression fitting or the hose
nipple in by hand. Tighten the compression fitting or the hose nipple using the fork spanner (approx. 1/4
turn). Close the open port of the regulator with a gasket and a G 1/4" protection plug, screw gas tight.
Mounting the protection plug
Close the open port of the regulator with a gasket G 1/4" – 11.2 x 5.5 x 1.5 mm and a G 1/4" protection
plug, screw gas tight
6.3 Mounting and operating the shut-off valve V 40
Install the diaphragm shut-off valve as a preliminary shut-off device between the wall adapter and the
point of use regulator.
Danger! Before starting assembly, de-pressurize the gas supply system. Depending on the type of gas,
remaining gases in the tubes must be removed. Danger of ignition, explosion or poisoning!
6.3.1 Mounting on the wall adapter with g 3/8" male thread
Tools: Fork spanner SW 36 parts: seal 14 x 9 x 2 mm. Center the gasket with the aid of the spigot on
the male thread connector. Put the gasket on the spigot. Screw the R 40/R 12 by hand onto the thread
connection. Hold the regulator at 45° in front of the required position while tightening the swivel nut
quick coupling with the fork spanner. Please only use the fork spanner SW 36 which can be obtained as
an accessory. With increasing torque, the regulator is turned as well. Tighten the quick coupling until the
regulator has reached the desired position. Thus you will have a gas tight connection.
Danger! With C
H
only use wall adapter made of stainless steel!

6.3.2 Operating the shut-off valve V 40
Open and close the valve by turning the operating lever. Turn the lever by 90° respectively. The lever
easily clicks into place in the open and shut position.
6.4 Mounting and operating the regulating valve V 50
The regulating valve V 50 has a 6 mm outlet compression fitting. Should you require a different size,
you can obtain the correct size with a reducing fitting. Please pay attention to the permissible nominal
pressure of the valve.
Danger! Before starting assembly, de-pressurize the gas supply system. Depending on the type of gas,
remaining gases in the tubes must be removed. Danger of ignition, explosion or poisoning!
