converting to SWCG - existing equipment compatability

[GregN]

Hi Folks - contemplating converting my 24' Round Matrix AGP (all resin) to salt-water. With the cost of pool bleach going up, and me getting older and tiring of manual chlorination, I'm really interested in going this route. Trying to determine if my existing pump is compatible with the Circupool RJ-30, and how to modify my set-up to go salt. Any feedback would be greatly appreciated as my knowledge about SWCG is limited to what I have been able to gleem from this forum.

1) My current pump is the Hayward Matrix 1 HP 2-speed model -SP15922S (speed is selected manually with switch on pump). Is there a minimum flow rate required to run the SWCG? I presently run this pump 8 hours a day on the LOW setting. Can I run the pump on LOW with the RJ-30 - is there enough flow to work with the salt cell?
2) My pump power cord terminates in a 3 prong plug that gets plugged into a dedicated GFCI outlet (110v). From what I have understand, I will probably want to install an intermatic timer that the SWCG and pump will connect to so the pump and SWCG go on/off simultaneously. Can I convert my pump from a plug to hardwire installation to connect with the timer?
3)Is my dedicated 20 amp breaker/110 line sufficient to power the pump and SWCG?
4) Is there a particular model of intermatic timer best suited for this application?
5) Is there a better way to go about this? Am I on the right track with supplying power to timer, and then pump and SWCG are wired to timer?
6) is there anything else I need to consider for this install?

Thanks,
Greg

Most SWCG need about 20 GPM to function so your pump should be able to do that.

Yes but you also could take the power feed to the receptacle and have it controlled by the timer. The timer would act as a switch to the receptacle.

3)Is my dedicated 20 amp breaker/110 line sufficient to power the pump and SWCG?

Yes 20 amp is good for both

4) Is there a particular model of intermatic timer best suited for this application?

The T101 is a basic timer. Just ensure it is 120V for your system

It is always best to cut power to the SWCG when the pump is off so yes - you are on the right track.

Thanks for the response Herman. Installing the timer before the receptacle, and having it serve as a switch, certainly simplifies the install. That was a good tip!
