Overflow box pipes: Make sure that that the O-rings are in position on
the threaded connectors before assembly. To ensure correct assembly,
firmly hold the threaded connectors from inside the cabinet and tighten
well by hand. Do not use tools. Avoid unscrewing the pipes from the
overflow box once assembled as the locking mechanism that prevents
counter-rotation will be less effective.
Sump pipes: Make sure that that the O-rings are in position on the
connectors before assembly. After assembly check that the pipes are
vertical and the securing nut is holding the pipe in position. Do not use
tools and do not overtighten.
Overflow Box Cover: The overflow box cover reduces noise from the
water fall of the surface skimmer. If you wish to use the rear wall of
the overflow box for mounting equipment such as lighting, break out
the section of the cover as shown in the graphic manual. After breaking
out the removable section, smooth the remaining edge with a file or
sandpaper.
