I had a power outage last night that caused my return pump (which also feeds the chiller) to freeze. While trying to make it work, I cut the flow to the chiller. When I put everything back together I forgot to turn the flow back to the chiller. I woke up this morning and realize that. .. The chiller must ave kicked on for a few hours without flow in it. I turned the flow back on but nothing is coming out... did the water left inside the chiller froze? what do I do?
