Could be a DE -- the imagery on Haywardnet was sparse. I've always avoided Hayward's filters, so my experience is limited. But, Sta-Rite has a single shell (System3) they use for DE, sand & cartridge. Hayward may be copying them.

The "Emerson 1081" is just the motor info, not the pump. The pump is a Hayward Super (not Super II) -- those I know. Likewise, the "automatic feeder) is just Hayward's standard feeder with the tiny orifice that ALL the pool water has to get through. Also, has an adjustment valve that rarely works -- your choice, but you'd be best served by getting rid of it. If you want a tablet chlorinator get a Rainboy 320 (Pentair product, now).

Posting pictures for the parts will get you lots of posts, but it won't get you ready to re-assemble the stuff. Hire it done; find out when they're coming; watch and make notes . . . and then DIY *next* year.
