The PSU 15B acts as a high-pressure cut-out (HP cut-out). It monitors the discharge pressure from the compressor. If the pressure exceeds a safe setpoint (due to a condenser fan failure, blocked coil, or overcharge of refrigerant), the switch trips and shuts down the compressor to prevent catastrophic failure or rupture.
The manual specifies that the switch should be mounted vertically on a wall or bracket. While the unit can function in other orientations, vertical mounting ensures that condensation or oil residue does not accumulate inside the switch housing, which could damage the electrical contacts or the bellows mechanism.
Use an open-ended wrench on the die-cast aluminium hex body flange. Do not twist the plastic casing to tighten the assembly.
