Closing Polaris pool cleaner line

[74shark]

Thanks, I have a Polaris 180 with a booster pump. The booster pump has a line with a closing valve coming from the filter, and then a line from the booster pump underground into the pool which connects to the Polaris when in use. I have blown out the skimmer and the two pressure lines, but not the cleaner line. I removed the plug from the front of the booster pump closed the valve coming from the filter and tried blowing that line through there but I did not get any air in the pool.

Can anyone provide any guidance?
