Cut and paste:

The no. 2 fan cycles in response to changes in liquid pressure. The switch cycles the fan off at 160 ± 10 psig (1103 ± 69 kPa) as pressure decreases, and cycles it back on at 255 ± 10 psig (1758 ± 69 kPa).


Pressurestat (psig)
High Cutout 426 ± 7
Cut-in 320 ± 20
Low Cutout 27 ± 4
Cut-in 67 ± 7
