[a] CO2 GAS CYLINDER
WARNING
Handle the regulator with care to have no impact on it, or the pressure gauge may not read accurately.
Stand the CO2 gas cylinder upright, and fix it securely with the accessory chain.
Keep the CO2 gas cylinder away from direct sunlight or temperatures above 40°C.
1) Open the main valve of the new CO2 gas cylinder for a second to blow dirt and
dust off the joint.
Note: Keep your face away from the cylinder.
2) Check the regulator gasket. If it is out of position or damaged, gas may leak
out.
3) Install the regulator on the CO2 gas cylinder. Tighten the nut securely to a
torque of 8 Nm so that the level gauge will be upright.
4) Open the main valve, and check the nut for gas leak (sound). If gas is leaking,
retighten the nut.
5) After finishing the connections, turn the adjust dial to ensure proper pressure
as listed below.
[b] PRESSURE RANGE
Adjust the CO2 gas pressure to the following range (reference).
Beer Keg Temperature Gas Pressure
10°C 0.15 - 0.20 MPa (Scale 1.5 - 2.0)
20°C 0.22 - 0.25 MPa (Scale 2.2 - 2.5)
30°C 0.32 - 0.35 MPa (Scale 3.2 - 3.5)
The appropriate keg pressure depends on the type and temperature of beer. Adjust the gas pressure according to the beer
company’s instructions. Insufficient pressure may result in excessive foaming.
[c] EXTERNAL CO2 GAS LINE
NOTICE
Cut the gas hose with a specialized tool such as hose cutter. Do not use scissors, or the gas hose may be crushed to cause
gas leaks.
Do not disconnect and reinsert the gas hose. Cut it about 20 mm before reuse.
Cut the hose end vertically, insert it securely into the quick joints, and check for gas leaks.
1) Determine the positions of the CO2 gas cylinder and beer keg to make the gas hose length within 1.4 m.
2) Cut the gas hose to have a vertical cutting plane.
3) Insert the gas hose into the quick joints on the keg coupler and regulator. Pull the hose hard to check for tight connections.
4) Use the adjust dial to check for gas leaks.
Quick Gas Hose Joint
1) To insert the gas hose into the quick joint, push it all the way in.
2) To disconnect the gas hose from the quick joint, push it with fingers as shown and
pull it out.
