I must say electronics on carpet like that with the risk of static shock when touching the unit would kind of worry me. Id place an anti static mat under those personally if they had to be ran on carpet or a rug like that.
you are correct if you look at tv set shelf in the picture there is a grounding bar just at top center
I ground myself on it before I touch units.
I moved unit into garage for testing over the week end.
I did a you tube video.
it is not ready uploads are slow.

Your video will be live at:
https://youtu.be/auakWENgP8wyou will note unit is laying on fiberglass welding blanket in a sound proof setup for the testing it is shock protected.
Sound meter failed at end of video so I will do another one later today.
the gear works very well in garage and I certainly could run it
without pissing off my wife.
1625 watts and 27200 gh = 59.7 watts a th
so if all s15's do 1625 watts and 27.2 th
and my m10's do 2200 watts and 31.2 th
both on full speed it will be a hard call as to which to pick.
s15's cost me a lot more then m10's
maybe 1650 with trump tax. 1285 without tax
m10's are under 900 without the trump tax.
So far My math shows me the s15 has to net to 1000usd to equal an m10 at 875.00 usd
So If I expand I still favor m10's with the pricing I get.
m10 at 875 no tax
s15 at 1285 no tax
note running on mmpool there is no asdic boost
so the 1625 watts could be better on pool.ckpool.org
will make a new video on SAT testing other pool
