As per my pump manual, the suction cleaner and vacuum plate should be connected only after the pump is primed.
Connect cleaner plate and hose to skimmer/wall suction only after all air has been purged from the top ofthe hair and lint pot of your Viron Pump.
I understood cleaner plate means vacuum plate in the above statement and am confused how I can connect a vacuum plate when pool is at prime (high speed). When pool pump is running, I wont be able to place the vacuum plate and lock it in place. The vacuum plate I have looks like this
Have I misunderstood what the manual says? Or is there a technique I am missing?
