Air-Cooled Units.
The condenser fan switch mounted to the frame (lower right side) (FIGURE 9-
5B) (CPS) is used to regulate the head pressure. This is an adjustable pressure switch located on the
right-hand front of machine. It controls the operation of the condenser fan motor(s) through a
contactor (FC) (FIGURE 6-2) located in the control panel. The switch is set to cycle the fan
motor(s) “On” at 210 psig and “Off” at 190 psig for R-22 and “On” at 250 psig and “Off” at 230
psig for R-404a. Higher settings may be necessary for 0
° F and below ambient conditions to assure
there is enough warm gas for ice harvesting.
