6) PRESSURE SWITCH OPENS
As the compressor is still running while valves A and B are closed, the suction pressure will
gradually decrease until reaching to 0.10 PSI, thus causing the pressure switch to open and
cut off both compressor and condenser fan. The system will remain in this configuration
until one out of A or B valves will open again to claim refrigerant to its circuit, causing the
suction pressure to increase and the pressure switch to close again in order to engage
compressor and condenser fan.
