Hi folks - We had a new pool finished last fall, including a Glacier chiller. I'm just now trying the chiller, since the heat is picking up and I'm pretty sure it's not plumbed correctly. My equipment pictures are attached, but here is a diagram of how it appears to be set up:
As you can see, there are no check valves preventing back flow and also no dedicated return line. Given that the chiller was in the original plans, I believe the chiller should have had it's own dedicated return line. The way mine is currently plumbed, it looks like water will just bypass or cavitate in the chiller, since the chiller outlet will have back pressure from the bypass.
The guide also says you set the valves at 2 o'clock or so and leave them there all season and to only use the chiller with one variable pump speed. If that's the case, I would need to go move these valves every time we turn on the hot tub, because the filter pump runs at a much higher speed and will overflow the chillers. Their diagrams show either being able to bypass the chiller when running the hot tub or the dedicated return line.
I also read through this old thread which seems to confirm my setup is atypical.
Thoughts?
Kurt
