Having problems with your Northstar Professional Series Pressure Washer 4000 PSI ?

I recently purchased a northstar 4000 psi pressure washer. I had the same series pressure washer for the past 6 years and used a downstream chemical unloader quick connect to pull chemical. I attached it to the pressure washer and it is not pulling. I havent modified anything and I dont want to pull chemical through my machine.
