DIN477 Connection

(EU standard CO2cylinders with fitted gas control valve)

Instructions for Use

CO2is supplied in a compressed gas cylinder that is pressurised to a high pressure of

approx. 60 bar (900psi). In order to use this gas in an aquarium system the flow of gas has

to be reduced to more manageable levels. The adjustable V2Pressure Regulator

reduces the flow of CO2from the cylinder and allows the accurate adjustment and dosage

of CO2into the aquarium.

1. Ensure that the V2Pressure Regulator is compatible with your chosen CO2cylinder.

2. Before connecting theV2Pressure Regulator to the CO2cylinder ensure that the

pressure adjustment knob (see Photo 1 above) on the pressure regulator is rotated

clockwise to the fully closed position.

3. Place your CO2cylinder in a stable position on a level surface and connect the regulator

securely to the CO2cylinder by turning the connecting lock nut (see Photo 1 above)

clockwise until it is fully hand tightened. Then, using a 28mm spanner or similar tool,

secure the connection. Caution: For safety, it is good practice when attaching a

regulator to any compressed gas cylinder to point the regulator dial away from you.

4. The V2Pressure Regulator has an outlet hosetail designed for standard 6mm (1/4”)

flexible tubing with a hosetail locking nut for added safety (see Photo 1 above).

5. Unscrew the hosetail locking nut (see Photo 2) and then thread one end of your chosen

flexible tubing through the hole in the end of the locking nut, and attach this same end to

the outlet hosetail (see Photo 3).

6. Re-attach and secure the hosetail locking nut.

Please note: We strongly advise that a non return valve is installed in the flexible tubing

between the CO2regulator and your calcium reactor or other chosen piece of equipment to

prevent water flowing back into the regulator.

7. Connect and secure the other end of your flexible tubing to your calcium reactor or other

chosen piece of equipment.

8. Double check that all connections have been made correctly and are secure.

9. You are now ready to open the gas control valve on the CO2cylinder. As soon as you

have opened the valve on the CO2cylinder the dial on the pressure regulator should

indicate a reading. If the connection to the CO2cylinder has been made correctly

there will be no escaping gas (and no hissing sound will be heard). However, if gas is

escaping (and a hissing sound is heard) please close the gas control valve on the CO2

cylinder and then reconnect and tighten the regulator as described in 3 above.

10. You are now ready to open the pressure adjustment knob (see Photo 1) on theV2

Pressure Regulator by turning it anti-clockwise, and to start dosing CO2according to your

application and equipment requirements.

CAUTION

• The adjustment on the V2Pressure Regulator is very precise and the pressure adjustment

knob must be turned slowly and carefully to avoid any problems with dosing.

• Do not apply any lubrication to any parts of the regulator.

• Do not attempt to modify or change any parts of the CO2regulator.

• The V2Pressure Regulator cannot be used in conjunction with a solenoid valve.

• Keep all CO2cylinders away from heat.

When to Replace the CO2Cylinder

During normal operation the pressure inside the CO2cylinder will remain fairly constant until

the CO2cylinder is almost empty. Therefore the easiest way to determine when the CO2

cylinder needs replacing is to note the pressure reading on the V2Pressure Regulator dial (see

Photo 1) when the CO2regulator is first connected to a full CO2cylinder. A significant drop in

the pressure reading should indicate that the cylinder is almost empty and should be replaced as

soon as possible. Please note: The total gas output from a CO2cylinder will be dependent on

both the temperature at which the cylinder is filled and the ambient temperature it is used at.

Disconnecting/Replacing the CO2Cylinder

1. Ensure that the gas control valve on the CO2cylinder is fully closed.

2. Undo the hosetail locking nut on the outlet hosetail (see Photo 1) and remove the flexible

tubing from the outlet hosetail. Any CO2trapped inside the tubing will be released and a

hissing sound from escaping gas may be heard.

3. Turn the pressure adjustment knob on theV2Pressure Regulator clockwise to the fully closed position.

4. Carefully disconnect the V2Pressure Regulator from the CO2cylinder by undoing the

securing nut on theV2Pressure Regulator with a 28mm spanner or similar tool.

5. Reconnect as described above.
