NOTES:
1 FCPS1 = Fan cycle pressure switch 1 cycles fan 3 in
response to condensing pressure.
2. FCPS2 = Fan cycle pressure switch 2 cycles fan 4 in
response to condensing pressure
3. FCPS3 = Fan cycle pressure switch 3 cycles fan 3 in
response to condensing pressure.
4. FCPS4 = Fan cycle pressure switch 4 cycles fan 4 in
response to condensing pressure
5 In the above applications where a fan is being shared by two
different refrigeration circuits, the FCPSs (FCPS1 and 3 or
FCPS2 and 4) are in parallel so that if either circuit needs the
fan to be on, it will be on
