I thought I would share some pictures of my new RJ60+ install - could be helpful to other folks who plan to switch to SWCG. For me it was an opportunity to also fix some unrelated issues:
Having everything in place and running on a bypass cell, I balanced the water and dissolved CYA using a sock hanging in front of returns. The K-1766 test kit showed that there was already 1000 ppm of salt, so based on the estimated pool volume, I added 10 bags of Solar Crystals from Lowes. The next day K-1766 showed 3000 ppm. Added 3 more bags. Currently, K-1766 shows 3600 ppm and the RJ60 controller displays an instantenous salinity oscilating between 3700 and 3800 ppm.
The advertised chlorine production of RJ60+ is an equivalent of 3.1 lbs of 100% abstract liquid chlorine at 100% duty cycle over 24 hours, so assuming my single speed pump is running only 6 hours a day, the following is true:
0.775 lbs of 100% chlorine at 100% duty cycle over 6 hours
7.750 lbs of 10% chlorine at 100% duty cycle over 6 hours
3.875 lbs of 10& chlorine at 50% duty cycle over 6 hours
That's about an equivalent of half a gallon of 10% liquid chlorine per day, which is the amount my New Jersey pool consumes on an average day. So as a starting point I set the duty cycle to 50% and dialed the following run times into Intermatic P1353 timer:
Main pump: 6:00am - 12:00pm
RJ60: 6:05am - 11:55am
That was the first attempt. By now I increased the running time to 7 hours and the duty cycle to 60%. Chlorine contents in the early morning is between 3 and 4 ppm with CYA 60 ppm, which is what I need. Maybe in the longer run chlorine will go up, so then I will adjust the parameters down a little bit.
I am very happy with RJ60+. Hopefully it will stay that way for years to come. Now to the photos.
This is the old setup, with a Stenner pump and a barrel of liquid chlorine:
Another photo of the old setup. The minipad is very crowded - the only option available for the SWG cell is a vertical mount... or a drastic redoing of the whole shebang, which I didn't look forward to. I reused the existing plumbing to the maximum.
And this is the new setup with Circupool RJ60+. Thanks @cowboycasey for your simple and elegant design of the stand: Do I need to shelter the panel? SWG Install questions.. I would never know those "OZ" posts are waiting for me at Lowes!
Electrical diagram - subpanel and Intermatic P1353:
Bonding wire continuity test:
- The old stand was small, rotten and placed too close to the equipment pad - there was not enough room to remove the filter's clamp ring for cleaning. (Remedy: built a new stand.)
- The electrical subpanel was all rusted and a sore to the eyes - it didn't inspire confidence in the pool safety. (Remedy: wired a new subpanel.)
- The pool has a 120V / 300W underwater halogen installed 33 years ago by the previous owner. I'm just scared to swim in a pool with a submerged old, high-voltage lamp. (Remedy: permanently removed power from the lamp. Perhaps some time in the future I will replace the halogen with a low voltage LED and reconnect it back.)
- Improve the safety and bring the pool to comply with the current NEC. (Remedy: installed GFCI circuit breakers in the subpanel.)
