Swabbie for ATB 840v2

[Fishie]

Hi ...I need a swabbie for an ATB 840v2

 

it measures 7" across the outer part of the top lid which is A on your site.

 

some websites said go 8" but i was confused whats needed for me

Go with your personal measurements- ATB is notorious for changing the dimensions of their skimmer collection cups on nearly every revision of skimmer.  There are definitely a few different versions of the 840 "v2".  I know we have people who have used 7" Swabbies on ATB 840 series skimmers, so if yours measures 7", then that is what you need.

[Fishie]

ok ill go with 7 then..

 

can the 7" increase little more if needed 

[ctenophore]

Yes it fits up to about 7.75"

what is the circumference of the motor housing on the swabbie ?

I have placed my order through ERC and wanted to make a hole wide enough on my lift up wooden lid where the skimmer is to allow the motor housing to come out.

 

I also noticed on the site that there is a swabbie conversion kit available. I am guessing this isn't needed on new orders since they would already have an upgraded motor. Are these new housings black in color ?

3.75" diameter. Circumference would be pi×diameter or 11.78.

 

The conversion kits are only for old swabbies, about 2 years old or more.

awesome thx for understanding what i should have asked and correcting me :-)

so its been little over a week since I've had mine going and i see a brown layer around the top 25% part of my neck...should it be clean or there can be a light layer ..

also the top of the wiper is collecting a good amount of gunk

 

which way should the wiper face when running...im trying to set it to drag since its flexible to get more contact...but it doesn't get a clean sweep everywhere

[ctenophore]

You can tighten it down against the neck a little more. The wiper is designed to be flexible like that. Bump it out about a millimeter, then tighten down the stainless steel nut to keep it from sliding back in.

[ctenophore]

Doesn't matter which way the wiper faces. It's bidirectional.

does the swabbie need to be on port 4 or 8 of the apex aqua controller...i was testing my adjustment for the wiper and noticed that it isn't shutting off 

 

is this one of the things that needs to be on the low voltage relay ports of the apex aqua controller?

[ctenophore]

It only draws about 2-3 watts, so very possible. I'm not sure what outlet mine are in.

[Fishie]

yea i moved it over to 8 and it worked fine...oddly enough it was working ok in the non relay ports initially but i guess those aren't always predictable for such a low voltage draw...all good now tho ty
