Welcome to our forum.
Look in the middle of a double ended 125sq. ft. filter. There is a wall close to one side. That section was used to handel the small circulation pump. That wall is why you cannot use that filter.
Straight from the manual:Your Sundance hot tub is equipped a high-efficiency MicroClean II filter cartridge under the filter lid (Figures G-J, Page 18-21). Debris is filtered by the circulation pump drawing water through this cartridge 24-hours a day, 7 days a week (unless programmed otherwise.) To ensure optimumperformance, replace this cartridge every 6 months or as needed. This filter cannot be cleaned and reused and MUST be thrown out after use.ALSO from the manual:Replacement MicroClean II filter cartridges may be purchased from your Sundance dealer. An optional pleated filter cartridge is also available from your Sundance dealer. This filter can be cleaned and reused for up to two years but does not maintain the same water quality and clarity as the standard MicroClean II cartridge.
I wonder if you choose to not replace the microclean II filter and just let the regular filter do the work?
The MicroClean II is the ONLY filter on the 880 series tubs.
Anne, I believe they are refering to the 125 sq. ft. traditional pleated filter that Sundance used in the past. They are the same size as the Microclean II, so they do fit. They are not reccomended.
The tubs weren't designed for them. That should be enough for you, but I have a feeling it's not.
The pleated filter was designed with 2 parts. 1 section for the ciirculation pump, and one for the 2 speed pump. The new filter has only 1 pump pulling through it because the filtration is totally separated from the main pump system. That pump will pull unevenly through the filter because of how it is seaparated. That is why it is not reccomended.
I'm sure that Noblewinds knows more about Sundance spas than the people that design/build them. I already said that it will "fit".
This is why the filter will not work. The filter that "fits" was designed as a 2 part filter. 1 section for the small circ pump, 1 section for the main pump. The 2 part filter will replace the microclean 1, but not the microclean II.
The double ended 125 sq. ft. filter will work for the microclean I filter setup. They both separate the ciculation pump from the main pump. If there is a double ended 125 sq. ft. filter with no wall, then I don't see why that wouldn't work.
Straight from the manual:Replacement MicroClean II filter cartridges may be purchased from your Sundance dealer. An optional pleated filter cartridge is also available from your Sundance dealer. This filter can be cleaned and reused for up to two years but does not maintain the same water quality and clarity as the standard MicroClean II cartridge.
If I'm a newbie looking at this discussion, I'm totally lost. Now someone quotes the manual and SURPRISE, it says something else.Why is THAT?Drewski
