Is the Regulator valve (secondary cut off) open all the way? If in the Closed or Off
position, or not fully open (straight down), then there is not proper air pressure coming
out of the regulator. If gauge shows proper pressure, and the secondary valve is all the
way in the open position, problem may be in the coupler.
*Hint – Red air hose will feel harder when under pressure than when there is no air
pressure.
Check to see if there is pressure to the coupler by pulling
out the pressure release valve. If there is pressure going
to the valve, there will be a hiss as the release valve
purges the air pressure. If no air hisses out, shut off the
air at the CO2 cylinder and the regulator, and unscrew
the red air hose from the coupler to inspect the ‘check
valve assembly’. Make sure all the parts are in proper
positions as seen in the image below. Also check that the
check valve itself is facing in the right direction, with the
tapered end facing into the the coupler, and make sure it has a slit in the tapered end.
You can see the slit if you squeeze the sides of the tapered end, as seen in the lower right
picture. If the valve does not have the slit, one can be made by just poking a hole at the
end of the tapered side of the check valve.
Can I Use Keg Cooler for Import Kegs?
As long as the keg is within the dimensions listed above, it should physically fit within
the unit. The coupler in this unit will not fit import beers. Other styles of couplers can be
purchased through
www.bannerbeer.com , or can most likely be found locally at stores that deal
in beer brewing or restaurant supply.
