After all of the screen sections and accessory pieces have been correctly positioned, slide 
them back as far as possible against the screen stops and secure with the screen hooks. 
The lips on all screens will always be facing down hill and should be lipped over the next 
screen.  
 
Then slid the ball trays into the ball tray rails below that screen set. This will keep the balls 
in place in the ball trays. The ball trays containing five balls per compartment do not have 
to be removed for screen changes on current model cleaners.  The balls should be 
checked periodically for wear.  If the ball diameters are less than 1-5/16 inches, or have 
lost some of their bounce they should be replaced.
