Upon arrival checked motors, electrical components, and pressures on 2 rheem split closet systems. AH 1 AND 2 both upstairs. Upstairs IV bulb still on but needs replaced. Replaced UV bulb on larger rheem unit AH (both AH next to each other). Cleared draon line and DeltaT excellent. Recommend Surge protectors for both units. Added existing equipment and left systems in good operating condition.
