Filter Cleaning - Unable to close the lid

[rkrgk]

Thanks Ben.
I had attached the picture with my previous reply(but for some reason, it looks as though you were not able to see it). And the manual you mentioned is the one that I referred to when taking apart the filter grid and putting back together. From the picture you posted, it is similar except that the pressure gauge is sort of protruding on top and the top lid is a bit more taller in my filter. Let me try to attach the picture again.

I *think* those are the same filters, but I'd suggest doing this:

1. Call Hayward support: 866-429-7665 for Arizona (I tried, I can't call that #)
2. Write down (or print, or have an email ready with) the link for this thread:

3. Ask the Hayward rep to LOOK at the picture in this link, and see what model it is.

Thanks for the number Ben!
I called at the number and spoke to a tech support. He told me that my unit is a DE6000.

[PoolDoc]

Were you able to find the matching manual?

[rkrgk]

Yes, He had to send fax me the manual, since the product is obsolete and replaced with DE6020.
But it seems as though most of the details in the manual that you mentioned matches this one except for the physical differences between the models.
I was able to put the filter back together, but when I started the pump, the pressure seems to be too high ~35psi. There might be something causing this high pressure. May be because I only replaced 3 of the 8 filter grids (and others I only cleaned with a garden hose and didnt use any chemicals). I still dont undertstand all the valves in my system, and I think my in floor cleaning system (caretaker 5 port valve) would need rebuilding/replacing.

[PoolDoc]

+ Gummed up DE grids can definitely cause a lot of back pressure, and poor filtration.
+ Caretaker systems waste enormous amounts of energy, and also cause a great deal of back pressure.
+ 35 psi on start up is WAY too high

[rkrgk]

Still the pressure is around 30 psi, so I kept it switched off for now. And turned my attention to the caretaker 99 pop up system. I took it apart to clean and check if the gears are worn out. The stainless steel net was kinda clogged, so I bought a replacement. The pistons seems to have lost a bit of strength, but I am just gonna try to clean everything and put it back to see if I can make it work.
But when I opened the gears inside the cam assembly, I was not that careful to note how they were placed against each other, and the whole gear system came apart. I searched how to find some information as to put all the gears back together at the right place, but seems there is no info available. Would you know how to put them back?
(I am talking about the plastic gears on the cam assembly). I could find rebuild kit instructions, but they all describe the cam assembly being held together with a rubber band and does not need to be assembled.
